Abstract

PROBLEM TO BE SOLVED: To green barren land of deserts to make them become croplands where plants such as crops, fruits, vegetables, and trees can be cultivated.SOLUTION: Water solution is dispersed from underground by using a bucket-shaped object 1, an expanded polystyrene box 1, or an expanded polylactic acid farming box 1, and sucked up by capillarity up to the surface, the cortex, of a desert. The bucket-shaped object 1 is buried underground such that nothing exists, except the sands of the desert, between the bucket-shaped object 1 and the cortex of the desert. The moisture contained in the sands of the desert supplies enough moisture to plants to culture, raise, and grow the plants such as crops, fruits, vegetables, and trees.

Description

An object of the present invention is to grow fruit trees, vegetables, and trees in the desert with a very small amount of water evaporation for watering the desert.

In addition, the present invention provides contamination to cesium, which is radioactivity or radiation (hereinafter abbreviated as radioactivity) such as cesium, plutonium, or other radioactive substances (hereinafter abbreviated as cesium). Paddy fields, fields, and other soils (hereinafter abbreviated as arable land, or soil) reduce the radiation dose of radioactive materials in cultivated land contaminated with radioactive materials such as cesium The purpose is to provide a cultivated land that can grow and grow safe plants that do not affect the human body.
Further, the present invention provides contamination to cesium, which is radioactivity or radiation (hereinafter abbreviated as radioactivity), for example, cesium, plutonium, or other radioactive substances (hereinafter abbreviated as cesium). Radiation of radioactive materials from a playground contaminated with radioactive substances such as cesium, where the playground (hereinafter referred to as the "playground" for short) is a kindergarten, elementary school, junior high school, high school, or other school The purpose is to provide a safe athletic field where the radiation dose of radioactive materials such as cesium is reduced below the reference value, which does not affect the human body by reducing the dose.

Further, using a polystyrene foam plate (1) or a polystyrene foam box (1) formed by mixing activated carbon or zeolite, which can efficiently absorb radioactivity such as cesium, cesium For the purpose of removing radioactivity, such as underground, which is contaminated with radioactivity, for example, made of polystyrene foam, the thickness is about 3 cm, or 5 cm, or about 10 cm in length and width, 45 cm × 45 cm or around 1 m of coconut shell activated carbon, Bacus activated carbon, carbon black, ketjen black, carbon nanotube, graphene, or zeolite (hereinafter, abbreviated as activated carbon or zeolite), Mixing and mixing the inside of the raw material for molding the expanded polystyrene, activated carbon or zeolite, the expanded polystyrene raw material Made of polystyrene foam, molded using the raw materials mixed in the material, cut polystyrene foam plates (1) or foam polystyrene boxes (1) in series and in parallel, then made of polystyrene foam From the top of the box (1), the soil (4) that has not been contaminated by radioactivity is embanked, and the embankment or embankment (hereinafter abbreviated as embankment) in which the foamed polystyrene box (1) is buried. ) Is used to remove radioactivity such as cesium contained in playground or cultivated land.

In the desert, the daytime temperature rises to over 50 degrees Celsius and the surface temperature of the desert surface (10) rises to around 80 degrees Celsius, so fruit trees grown in the desert, Even if water is sprayed from the surface of the desert to the vegetables and trees (hereinafter abbreviated as fruit trees or plants), the water will instantly evaporate, so fruit trees in the desert It is said that plants such as vegetables and trees cannot be cultivated.

In addition, due to an accident at a nuclear power plant in Fukushima Prefecture, the soil of many school playgrounds or the surrounding paddy fields, fields, cultivated land, etc. were contaminated with radioactive substances such as cesium, And in growing plants, areas that are above radiation doses that affect the human body and plants, such as school playgrounds or cultivated land, are occurring in a wide range of areas.

The biggest reason that plants, grains, fruits, vegetables, and trees cannot grow and grow in the desert is that the salinity of salt contained in the desert sand (4) is There are about 1000PPM. The salinity of the human body is about 300PPM. The salinity contained in the desert sand (4) is, for example, higher in the desert 2m than in the desert 1m. Furthermore, the phenomenon of desert time is that the salinity is much higher in 3m underground than in 2m underground. When an aqueous solution is sprinkled from the surface of the desert surface layer (10) onto the desert sand (4) having a high salinity, the salinity contained in the desert sand (4) is removed from the desert surface layer (10). The more water is sprayed, the more transpiration or evaporation (hereinafter abbreviated to transpiration), the surface of the desert (10), the surface of the desert, the salinity from the desert basement. As the water rises, on the surface of the desert, which is the desert surface layer (10), for example, if the salinity is 5000 PPM to 10,000 PPM and the surface of the desert surface layer (10) is sprinkled, The main reason is that the high salt concentration prevents the plant grains, fruit trees, vegetables and trees from growing and growing in the desert. Date palm is the most salt-tolerant plant on the earth. This date palm can grow and grow even in a desert with a salinity of 1000 PPM. Furthermore, Satsuma mushrooms can grow and grow even at about 800 PPM to 1000 PPM. The salt concentration contained in the sand (4) of the desert surface layer (10) is 1000 PPM. In order to prevent the salinity contained in this desert sand (4) from exceeding 1000PPM, water must be sprayed from the surface of the desert surface (10), and the desert surface (10) The salinity contained in the sand (4) on the surface will be maintained at 1000 PPM. As means for solving this problem, the cocoon-shaped object (1), the foamed polystyrene box (1), or the polylactic acid foamed agricultural box (1) (hereinafter abbreviated, cocoon-shaped) is described below. Using the object (1)), the aqueous solution is sprinkled from the underground, and when the aqueous solution is sucked up to the surface of the desert, which is the surface layer (10) of the desert, by a capillary phenomenon, the bowl-shaped object (1) And only the desert sand (4) that exists in the middle of the desert surface layer (10), and has buried the ridge-shaped object (1), for example, at a point 1m underground in the desert If you want to bury the dredged object (1) and sprinkle the aqueous solution, it will be deeper than the dredged object (1) that is buried 1m underground in the desert, deeper than 1m in the desert, Desert where the sand (4) contains salinity is the desert surface (10) From the raised to the surface, and inventions and discoveries to be able to blocking at the point that embedded trough-shaped object (1). Through this invention and discovery, research and development of agricultural technology that can prevent salt damage with high salinity contained in desert sand (4), the desert can become a granary in the very near future. It has sex. The purpose and problem of embedding the bowl-shaped object (1) will be described below.

Grains, fruit trees, vegetables grown in the desert where the daytime temperature rises above 50 degrees Celsius and the surface temperature of the desert surface (10) rises around 80 degrees Celsius, and A pipe made of vinyl chloride resin (1), or a pipe (1) (hereinafter abbreviated) cut vertically in one place, which is a pipe that sends water into the ground to plants such as trees. ) Or buried in the basement around 1m below the ground, and the desert sand (4) flows into the interior of the cocoon-shaped object (1). Install the water spray pipe (2) attached to the tip of the prevention valve (3) to prevent it inside the bowl-shaped object (1), and pass the water pipe (2) inside the bowl-shaped object (1). A field that is a cultivated land with a structure in which water is sprinkled and water is supplied to the sand (4) contained in the ridge-shaped object (1). Unlike the case where water is sprayed from the surface of the desert, the sand (4) in the interior of the cocoon-shaped object (1) is always moistened by adopting a structure in which the cocoon-shaped object (1) is buried underground. It can be made into the state which contains water. Furthermore, the moisture contained in the desert sand (4) has a high temperature of about 80 degrees Celsius on the desert surface (10), and the humidity is about 0%. The moisture contained in the desert sand (4) rises upward and upward, which is the direction of the desert surface layer (10), by capillary action. As a result, it is invented that the total amount of the water solution sprinkled through the desert underground, for example, the underground water pipe (2) around 1 m, rises by capillary action toward the desert surface (10). I made a discovery. The moisture contained in the desert sand (4) evaporates when it rises in the desert surface layer (10), thereby depriving the underground temperature. It will decrease to around 35 degrees Celsius, and it will be the optimum temperature condition for plant growth and growth. Further, by setting the humidity inside the desert sand (4) to 60% or more, or 70% or more (hereinafter, abbreviated to 65% or more), the plants are grains, fruit trees, vegetables, And plants such as trees absorb water that the desert sand (4) is hydrated, and the desert sand (4) that has a humidity of 65% or more absorbs moisture, and the plants grow and grow. It will be possible to do. It is a plant that uses very little water, even in dry deserts, with the goal of maintaining the moisture content of the desert sand (4) at 65% or higher. Grains, fruit trees, vegetables and trees can be grown.

Further, the cocoon-shaped object (1) is a plant that is buried in a basement around 1 m underground in the desert, and an aqueous solution is supplied to the interior of the cocoon-shaped object (1) via a water spray pipe (2). When plants such as cereals, fruit trees, vegetables, and trees are cultivated, the desert exists between the point about 1 m underground where the cocoon-shaped object (1) is buried and the surface of the desert (10) Grain, fruit trees, vegetables, and trees, which are the salt contained in the sand (4) of the plant, absorbs the salt every year and transpires by transpiration, so that the cocoon-shaped object (1) and the desert The salinity contained in the desert sand (4), which exists in the middle of the surface layer (10), decreases year by year. Moreover, there is an advantage that sugar content increases when plants such as Satsuma persimmon, tomato, corn, carrot, pumpkin, pineapple, and mango are cultivated using desert sand (4) having a high salinity as cultivated land.

Also, since the salinity of the salt contained in the desert sand (4) is high, in the desert, for example, the salinity contained in the desert sand (4) is as high as around 1000 PPM. Since the salinity concentration is high, it is the current state of the desert surface layer (10) that only plants of date palm can be cultivated at most. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) in which the plant cannot absorb salt from the desert basement by transpiration, the basement of the desert surface layer (10) is dug down, for example, about 30cm to 1m The purpose of digging the desert basement to form a cultivated land (7) in the desert basement by arranging styrofoam boxes (1) 30 cm high, 45 cm long and 45 cm wide in series and in parallel After burying foam filling (17) on all areas of the area to be cultivated land (7) in the basement of the desert, embedding by embedding (17), the surface of the foam foam box (1) The purpose is to form arable land (7) on top.

Furthermore, since the salinity of the salinity contained in the desert sand (4) is high, in the desert, for example, the salinity contained in the desert sand (4) is as high as around 1000 PPM. Since the salinity concentration is high, it is the current state of the desert surface layer (10) that only plants of date palm can be cultivated at most. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) where the plant cannot absorb salt from the desert basement by transpiration, the surface of the desert surface layer (10) is leveled, for example, the height is Cultivation on the surface of the desert surface layer (10) for the purpose of forming cultivated land (7) by arranging styrofoam boxes (1) of 30 cm in length and 45 cm in width and 45 cm in width in series and in parallel After arranging the polystyrene foam boxes (1) over the entire area of the ground (7), the upper part of the polystyrene foam box (1) is filled with, for example, a height of about 30 cm to 1 m (17) The purpose is to form cultivated land (7) on the surface of the foamed polystyrene box (1).

In addition, about 25% of the land on the earth is a barren desert. By making this barren desert desert green and making it a farmland that can cultivate plant grains, fruit trees, vegetables, trees, etc., the population will grow on the earth in the future and food The purpose is to eliminate the situation of shortage.

When cultivating crops in the desert, if the structure of the field, which is a cultivated land that does not release the sprinkled water, can be constructed, the desert can be easily leveled, creating a large-scale farmland There is an effect that can be.

In addition, a saddle-shaped object (1) made of vinyl chloride resin or the like is buried in the basement around 25 cm below the desert, and the interior of the saddle-shaped object (1) is routed through a sprinkling pipe (2). By making the structure in which water is sprinkled and water is supplied to the sand (4) contained in the bowl-shaped object (1), when water is sprinkled from the surface of the desert, the water instantly evaporates. However, if water is sprayed through the sprinkler pipe (2) inside the trapezoidal object (1) installed in the basement around 25cm below the desert, the sprinkled water will evaporate. Since the moisture does not escape, it has water retention, and the desert basement always contains moisture, so plants such as fruit trees, vegetables, and trees grow and grow in the desert. There is an effect that becomes an environment that can be.

Furthermore, using the water spray pipe (2), the fertilizer and agricultural chemicals required by plants such as cereals, fruit trees, vegetables, and trees are dissolved in the aqueous solution of the plant growing the aqueous solution. Since the fertilizer and the pesticide can be sprayed directly to the root using the sprinkler pipe (2), there is an effect that the fertilizer and the pesticide can be sprayed together with the aqueous solution efficiently.

In addition, from a basement of about 30 cm below the desert to the ground, a cardboard box (1) or a polylactic foamed agricultural box (1) (hereinafter abbreviated to a cardboard box or a polylactic foamed agricultural box) And a film (5) made of biodegradable plastic as a raw material was placed on the inner side surface of the cardboard box (1), and water was sprayed inside the cardboard box (1). By cultivating plants such as cereals, fruit trees, vegetables, and trees on a cultivated land with a structure in which a water spray pipe (2) is installed inside a corrugated cardboard box (1) that has a structure in which an aqueous solution is accumulated. A cultivated land with a structure where water can be stored inside the cardboard box (1) inside the cardboard box (1) at a low cost. Forming in the desert It makes a certain grain, fruit, vegetables, and the effect of that is possible to grow plants such as trees in the barren earth.

Further, from the basement around 30 cm underground in the desert to the ground, the cardboard box (1) or the polylactic acid foaming agricultural box (1) (hereinafter abbreviated as cardboard box or polylactic acid foaming agricultural box) In addition, an aqueous solution in which a film (5) made of biodegradable plastic as a raw material is placed on the inner side surface of the cardboard box (1) and water is sprayed inside the cardboard box (1). By cultivating plants such as cereals, fruit trees, vegetables, and trees inside the cardboard box (1) with a structure that accumulates water, water was sprayed inside the cardboard box (1) at a very low cost. By forming a cultivated land in the barren desert where the aqueous solution can be stored inside the cardboard box (1), planting grains, fruit trees, vegetables and trees in the barren land There is an effect that can be cultivated.

In addition, the corrugated cardboard box (1) has a structure that prevents the aqueous solution from leaking from the basement about 30cm below the desert to the ground. Polylactic acid foamed agricultural boxes made from biodegradable plastics (1), or containers made from other raw materials (1) (hereinafter abbreviated cardboard) The box (1) or the polylactic acid foaming agricultural box (1) is used as a cultivated land, for example. Grain, fruit trees, vegetables, and trees inside the polylactic acid foaming agricultural box (1), which has a structure in which water sprayed water is stored inside the buried polylactic acid foaming agricultural box (1). Na Cultivate plants by forming a cultivated land in a barren land desert, with a structure that allows water sprayed water to accumulate inside the polylactic acid agricultural box (1) Thus, there is an effect that plants such as cereals, fruit trees, vegetables and trees can be cultivated in barren land.

In addition, a polylactic acid foaming agricultural box (1) made by biodegradable plastics, which was made from corn derived from shells, developed by Cargill of the United States, was buried in the cultivated land. In the inside of the polylactic acid foaming agricultural box (1), which is a cultivated land where water sprayed water is stored, the cereals, fruit trees, The greatest advantage of cultivating plants such as vegetables and trees is that the cultivated land where the cultivation of plants and other plants has been completed is pulverized using a tractor together with the soil and the polylactic acid foaming agricultural box (1). And using a tractor to dig up the soil to soften the soil and cultivate the soil, a polylactic acid foaming agricultural box made from biodegradable plastic (1), and Biodegradable plastic The film (5) which is made as a material, using at the destination for storing the aqueous solution in the ground cereals, fruit trees, vegetables, and the effect of it is able to grow plants such as trees.

10 and 11 are made of biodegradable plastic as a raw material. For example, using a foamed agricultural box made of polylactic acid (1), the temporary name is made of polylactic acid. When an aqueous solution is stored in the bottom portion of the box (1) and plants such as cereals, fruit trees, vegetables, and trees are cultivated, the roots of the plants rot. For the purpose of preventing the root of this plant from decaying, a hole (6) is formed on the side of the polylactic acid foaming agricultural box (1) shown in FIGS. 10 and 11, Via this hole (6), the root of the plant can enter the inside of the soil surrounding the outer periphery of the polylactic acid foaming agricultural box (1), so that the polylactic acid foaming agricultural box ( By forming the hole (6) on the side surface of 1), there is an effect that can prevent the root decay of the plant.

Furthermore, the biodegradable plastic raw material is made of polylactic acid, which can be decomposed by microorganisms existing in the soil. In the box (1), microorganisms decompose in the soil, and the microorganisms exhale water and carbon dioxide. In addition, in the case of microorganisms that work in the absence of air, the microorganisms expel carbon dioxide and methane gas, etc., so that plants such as cereals, fruit trees, vegetables, and trees can be removed using polylactic acid foaming agricultural boxes (1). As a disposal method of the foamed agricultural box made of polylactic acid (1) remaining in the ground after cultivating, using a tractor, pulverize it with the soil that is the cultivated land using a tractor. It has the effect of digging up the soil and softening it.

Also, for the purpose of greening the desert, the raw material described above is different, but the raw material of expanded polystyrene is made of polystyrene. Just like expanded polystyrene, made of polylactic acid, made of expanded polystyrene. A foamed agricultural box made of polylactic acid (1) manufactured in exactly the same way as the container manufacturing method (1) is used as a cultivated land. For example, a groove having a depth of 30 cm and a width of 50 cm is used as a cultivated land. In a field, a groove having a depth of 30 cm and a width of 50 cm is formed immediately below the ridge, and the height of the groove formed in the area directly below the ridge is, for example, height Is a polylactic acid foamed agricultural box (1) with a width of 30 cm, a width of 50 cm, a length of 1 m, and a wall thickness of 2 cm. (1) 畝 just below the heel And parallel buried for, and internal watering aqueous solutions can be accumulated the configuration of embedded polylactic acid made of expanded agricultural box (1). Thereby, it becomes the effect similar to the effect of a pond.

Sprinkling water from the surface of the desert sand (4), depositing inside the polylactic acid foaming agricultural box (1), and depositing inside the polylactic acid foaming agricultural box (1) The moisture contained in the desert sand (4) is present on the surface of the desert, on the surface of the desert by capillary action, and then in the inside of the polylactic acid foaming agricultural box (1). Moisture contained in the sand (4) is increased by capillarity in the upward and upward directions, so that the polylactic acid foaming agricultural box (1 ) And the desert surface (4), which contains water from the desert sand (4), is a plant grain, fruit tree, vegetable, and Cultivation of plants such as trees, growth, and sufficient moisture to cause the growth there is an effect that it can be fed to the plant.

In addition, for the purpose of greening the desert and cultivating plants such as cereals, fruit trees, vegetables, and trees, the soil (7) is, for example, 50 cm, 1 m, or 2 m (hereinafter abbreviated from the ground surface). (1), a bowl-shaped object (1), or chloride made of vinyl chloride resin or other resin (hereinafter abbreviated as vinyl chloride resin) at a depth from the surface of the earth before and after Made of vinyl resin, for example, a pipe with a diameter of 30 cm is cut in half, a bowl-shaped object (1) with a diameter of 30 cm, or a corrugated cardboard box (1), or a cardboard box with water resistance (1) Or a polystyrene foam box (1) made of polystyrene, a polylactic acid foamed agricultural box (1), a box made of other materials (1), or a container made of other materials ( 1) (hereinafter abbreviated Then, bury a saddle-shaped object (1) or a pipe, box, or container (1) obtained by cutting a part of the pipe in the longitudinal direction at a depth of about 1 m from the ground surface. The aqueous solution supplied through the prevention valve (3) that prevents the inflow of sand (4) from the ground surface through the water spray pipe (2) is supplied to the polylactic acid foaming agricultural box (1). Desert sand (4) deposited in the inside of the polylactic acid foaming agricultural box (1) by watering an aqueous solution sprinkled from the ground surface to the desert sand (4) deposited inside Next, the aqueous solution is supplied from the ground surface via the water spray pipe (2), and the desert sand (4) deposited inside the polylactic acid foaming agricultural box (1) is hydrated. The water content of this desert sand (4) containing water increases to about 80 degrees Celsius during the day, so the water content of the sand (4) on the desert surface is close to 0%. State. When the desert surface sand (4) is in a state where the moisture content of the desert surface sand (4) is close to 0%, and the desert sand (4) is dry, it is buried about 1 m from the surface. The sand (4) flows into the desert sand (4), which is deposited inside the foamed agricultural box made of polylactic acid (1), from the ground via the water pipe (2). In the aqueous solution that has passed through the prevention valve (3) that prevents water from flowing, the desert sand (4) that accumulates inside the foamed agricultural box (1) made of polylactic acid is hydrated. The aqueous solution containing water from the desert sand is present on the surface of the desert, on the surface of the desert, and then inside the foamed agricultural box made of polylactic acid (1). Since the moisture contained in the sand (4) rises upward and upward due to capillary action, the polylactic acid foaming agricultural box (1) embedded in the ground and The water that the sand of the desert (4) contains in the middle of the desert surface cultivates, grows, and grows plants such as grains, fruit trees, vegetables, and trees. There is an effect that it is possible to supply the plant with sufficient water to make it go.

Furthermore, for the purpose of greening the desert and cultivating plants such as cereals, fruit trees, vegetables, trees, etc., inside the soil (7), for example, 50 cm, 1 m, or 2 m (hereinafter abbreviated) from the ground surface. (1), a bowl-shaped object (1), or chloride made of vinyl chloride resin or other resin (hereinafter abbreviated as vinyl chloride resin) at a depth from the surface of the earth before and after Made of vinyl resin, for example, a pipe with a diameter of 30 cm is cut in half, a bowl-shaped object (1) with a diameter of 30 cm, or a cardboard box (1), or a cardboard box with water resistance (1) Or a polystyrene foam box (1) made of polystyrene, a polylactic acid foamed agricultural box (1), a box made of other materials (1), or a container made of other materials ( 1) (Hereafter, Then, bury a saddle-shaped object (1) or a pipe, box, or container (1) obtained by cutting a part of the pipe in the vertical direction at a depth of about 1 m from the ground surface. The water solution supplied from the ground via the water spray pipe (2) and the prevention valve (3) for preventing the sand (4) from flowing into the polylactic acid foaming agricultural box (1) The desert sand (4) deposited inside is fed with an aqueous solution sprinkled from the ground surface, and the desert sand (4) deposited inside the polylactic acid foaming agricultural box (1) ) Is supplied with an aqueous solution from the ground via the water spray pipe (2), and the aqueous solution is added to the desert sand (4) deposited inside the polylactic acid foaming agricultural box (1). The water content of this desert sand (4) containing water increases to about 80 degrees Celsius during the day, so the water content of the sand (4) on the desert surface is close to 0%. State. When the desert surface sand (4) is in a state where the moisture content of the desert surface sand (4) is close to 0%, and the desert sand (4) is dry, it is buried about 1 m from the surface. The sand (4) flows into the desert sand (4), which is deposited inside the foamed agricultural box made of polylactic acid (1), from the ground via the water pipe (2). In the aqueous solution that has passed through the prevention valve (3) that prevents water from flowing, the desert sand (4) that accumulates inside the foamed agricultural box (1) made of polylactic acid is hydrated. The aqueous solution containing water from the desert sand is present on the surface of the desert, on the surface of the desert, and then inside the foamed agricultural box made of polylactic acid (1). Since the moisture contained in the sand (4) rises upward and upward due to capillary action, the polylactic acid foaming agricultural box (1) embedded in the ground and The water that the sand of the desert (4) contains in the middle of the desert surface cultivates, grows, and grows plants such as grains, fruit trees, vegetables, and trees. There is an effect that it is possible to supply the plant with sufficient water to make it go.

Also, for example, a saddle-shaped object (1) having a diameter of about 30 cm is embedded at a depth of about 1 m underground in a desert, and an aqueous solution is valved inside the concave shape of the embedded saddle-shaped object (1). By flowing an aqueous solution via (8), a waterway or a water vein (hereinafter abbreviated as a water vein) of a population is artificially formed around 1 m underground in the desert. When water is sprinkled from the surface of the desert, the aqueous solution evaporates instantaneously, but the aqueous solution is injected to the place around 1 m below the desert via the valve (8) shown in FIG. In this case, since the aqueous solution does not evaporate, the aqueous solution can be supplied to the sand of the desert at about 1 m underground. This aqueous solution containing water from the desert 1m below the desert has a high temperature on the desert surface of around 80 degrees Celsius and is dry, so it is about 1m deep in the desert. The aqueous solution flowing inside the cocoon-shaped object (1) that is buried rises to the surface of the desert, which is the upper direction, by capillary action. When the aqueous solution flowing inside the cocoon-shaped body (1) rises on the surface of the desert due to capillarity, the water vaporizes and the temperature in the desert is high. Will be taken away. Even if the surface temperature of the desert has risen to around 80 degrees Celsius, the underground temperature in the desert will remain at around 35 degrees Celsius. As described above, a very small amount of an aqueous solution is allowed to flow around 1 m below the desert, thereby lowering the temperature of the desert ground and supplying moisture to the desert underground. As a result, we have invented and discovered that even in the desert, it is an optimal land for cultivating crops such as cereals, fruit trees, vegetables and trees. Thereby, there exists an effect which can grow corn, Satsuma mushroom, carrot, Japanese radish, Chinese cabbage, cabbage, tomato, grape, yam, pineapple, raccoon, garlic, onion, burdock, eucalyptus, and the like.

Further, for example, a saddle-shaped object (1) having a diameter of about 30 cm is embedded at a depth of about 1 m underground in a desert, and an aqueous solution is valved inside the concave shape of the embedded saddle-shaped object (1). By flowing an aqueous solution via (8), a waterway or a water vein (hereinafter abbreviated as a water vein) of a population is artificially formed around 1 m underground in the desert. When water is sprinkled from the surface of the desert, the aqueous solution evaporates instantaneously, but the aqueous solution is injected to the place around 1 m below the desert via the valve (8) shown in FIG. In this case, since the aqueous solution does not evaporate, the aqueous solution can be supplied to the sand of the desert at about 1 m underground. This aqueous solution containing water from the desert 1m below the desert has a high temperature on the desert surface of around 80 degrees Celsius and is dry, so it is about 1m deep in the desert. The aqueous solution flowing inside the cocoon-shaped object (1) that is buried rises to the surface of the desert, which is the upper direction, by capillary action. When the aqueous solution flowing inside the cocoon-shaped body (1) rises on the surface of the desert due to capillarity, the water vaporizes and the temperature in the desert is high. Will be taken away. Even if the surface temperature of the desert has risen to around 80 degrees Celsius, the underground temperature in the desert will remain at around 35 degrees Celsius. As described above, a very small amount of an aqueous solution is allowed to flow around 1 m below the desert, thereby lowering the temperature of the desert ground and supplying moisture to the desert underground. As a result, we have invented and discovered that even in the desert, it is an optimal land for cultivating crops such as cereals, fruit trees, vegetables and trees. This has the effect of cultivating watermelon, corn, potato, carrot, Japanese radish, Chinese cabbage, cabbage, tomato, grape, yam, pineapple, raccoon, garlic, onion, burdock, and eucalyptus.

In addition, for the purpose of enabling rice cultivation in the desert, the vine (11) is formed after forming the ridge (11) on the surface of the desert surface layer (10) after leveling on the surface of the desert. ) On the surface of polyethylene film (12) or paper black multi (12), or green plastic multi film (12) made of biodegradable plastic, or other film (12) ( In the following, a film-shaped object is formed on the surface of the film (12) covering the surface of the bag (11) after the surface of the bag (11) is covered using the film 12). (1) is installed, and further, a sprinkler pipe (2) is piped inside the ridge-shaped object (1), and then, for example, desert sand (4) is laid on the surface of the ridge-shaped object (1). On the surface of the shaped object (1), heaped sand with a height of around 30 cm (4) Then, the bowl-shaped object (1), the film (12), and the sprinkling pipe (2) are embedded, and the inside of the bowl-shaped object (1) is passed through the valve (9) and the sprinkling pipe (2). The water solution needed to grow, grow, and grow plants such as grains, fruits, vegetables, and trees by sprinkling the aqueous solution on the ground will not leak and escape into the desert basement. Cover the entire area of the cultivated land (13) using a film (12) around 30cm underground, and the water sprayed through the water pipe (2) will not leak into the desert basement When configured, at the same time, a waterproof wall (14) is formed on the outer peripheral side wall of the cultivated land (13), and the aqueous solution is poured into the cultivated land (13) in a full state to enable rice cultivation. For the purpose of rice cultivation in the desert paddy field.

In addition, the most important reason is that the plant grains, fruits, vegetables and trees cannot grow and grow in the desert. The main reason is that the salinity of salt contained in the desert sand (4) However, there are about 1000 PPM. The salinity of the human body is about 300PPM. The salinity contained in the desert sand (4) is, for example, higher in the desert 2m than in the desert 1m. Furthermore, the phenomenon of desert time is that the salinity is much higher in 3m underground than in 2m underground. When an aqueous solution is sprinkled from the surface of the desert surface layer (10) onto the desert sand (4) having a high salinity, the salinity contained in the desert sand (4) is removed from the desert surface layer (10). The more water is sprayed, the more transpiration or evaporation (hereinafter abbreviated to transpiration), the surface of the desert (10), the surface of the desert, the salinity from the desert basement. As the water rises, on the surface of the desert, which is the desert surface layer (10), for example, if the salinity is 5000 PPM to 10,000 PPM and the surface of the desert surface layer (10) is sprinkled, The main reason is that the high salt concentration prevents the plant grains, fruit trees, vegetables and trees from growing and growing in the desert. Date palm is the most salt-tolerant plant on the earth. This date palm can grow and grow even in a desert with a salinity of 1000 PPM. Furthermore, Satsuma mushrooms can grow and grow even at about 800 PPM to 1000 PPM. The salt concentration contained in the sand (4) of the desert surface layer (10) is 1000 PPM. In order to prevent the salinity contained in this desert sand (4) from exceeding 1000PPM, water must be sprayed from the surface of the desert surface (10), and the desert surface (10) The salinity contained in the sand (4) on the surface will be maintained at 1000 PPM. As means for solving this problem, the cocoon-shaped object (1), the foamed polystyrene box (1), or the polylactic acid foamed agricultural box (1) (hereinafter abbreviated, cocoon-shaped) is described below. Using the object (1)), the aqueous solution is sprinkled from the underground, and when the aqueous solution is sucked up to the surface of the desert, which is the surface layer (10) of the desert, by a capillary phenomenon, the bowl-shaped object (1) And only the desert sand (4) that exists in the middle of the desert surface layer (10), and has buried the ridge-shaped object (1), for example, at a point 1m underground in the desert If you want to bury the dredged object (1) and sprinkle the aqueous solution, it will be deeper than the dredged object (1) that is buried 1m underground in the desert, deeper than 1m in the desert, Desert where the sand (4) contains salinity is the desert surface (10) From the raised to the surface, and inventions and discoveries to be able to blocking at the point that embedded trough-shaped object (1). Through this invention and discovery, research and development of agricultural technology that can prevent salt damage with high salinity contained in desert sand (4), the desert can become a granary in the very near future. There is a hidden effect.

Further, the cocoon-shaped object (1) is a plant that is buried in a basement around 1 m underground in the desert, and an aqueous solution is supplied to the interior of the cocoon-shaped object (1) via a sprinkling pipe (2). When plants such as cereals, fruit trees, vegetables, and trees are cultivated, the desert exists between the point about 1 m underground where the cocoon-shaped object (1) is buried and the surface of the desert (10) Grain, fruit trees, vegetables, and trees, which are the salt contained in the sand (4) of the plant, absorbs the salt every year and transpires by transpiration, so that the cocoon-shaped object (1) and the desert The salinity contained in the desert sand (4), which exists in the middle of the surface layer (10), decreases year by year. In addition, cultivation of plants such as Satsuma persimmons, tomatoes, corn, carrots, pumpkins, pineapples, and mangos using desert sand (4) having a high salinity as an cultivated land has the effect of increasing sugar content.

Furthermore, since the salinity of the salinity contained in the desert sand (4) is high, in the desert, for example, the salinity contained in the desert sand (4) is as high as around 1000 PPM. Since the salinity concentration is high, it is the current state of the desert surface layer (10) that only plants of date palm can be cultivated at most. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) in which the plant cannot absorb salt from the desert basement by transpiration, the basement of the desert surface layer (10) is dug down, for example, about 30cm to 1m The purpose of digging the desert basement to form a cultivated land (7) in the desert basement by arranging styrofoam boxes (1) 30 cm high, 45 cm long and 45 cm wide in series and in parallel After burying foam filling (17) on all areas of the area to be cultivated land (7) in the basement of the desert, embedding by embedding (17), the surface of the foam foam box (1) There exists an effect which can form a cultivated land (7) on it.

Also, since the salinity of the salt contained in the desert sand (4) is high, in the desert, for example, the salinity contained in the desert sand (4) is as high as around 1000 PPM. Since the salinity concentration is high, it is the current state of the desert surface layer (10) that only plants of date palm can be cultivated at most. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) where the plant cannot absorb salt from the desert basement by transpiration, the surface of the desert surface layer (10) is leveled, for example, the height is Cultivation on the surface of the desert surface layer (10) for the purpose of forming cultivated land (7) by arranging styrofoam boxes (1) of 30 cm in length and 45 cm in width and 45 cm in width in series and in parallel After arranging the polystyrene foam boxes (1) over the entire area of the ground (7), the upper part of the polystyrene foam box (1) is filled with, for example, a height of about 30 cm to 1 m (17) The cultivated land (7) can be formed on the surface of the expanded polystyrene box (1).

Furthermore, the polystyrene foam box (1) having a height of 30 cm, a vertical width of 45 cm, and a horizontal width of 45 cm as described in FIGS. 27, 28, 29, and 30, or polylactic acid foaming agriculture When a box (1) or a water-resistant cardboard box (1) (hereinafter abbreviated as a foamed polystyrene box (1)) is laid in the ground of the cultivated land (7), for example, 1 tsubo is 1.8 m Since the length is 1.8 m, four foamed polystyrene boxes (1) per square meter (4) are required in the vertical direction and four horizontal boxes (16). Since one side which is a field of the cultivated land (7) is 300 tsubo, the number of boxes required for the foamed polystyrene box (1) per one side is 4800. Further, the volume of the polystyrene foam box (1) is 30 × 45 × 45 = 60.75 m ³ because the height is 30 cm, the vertical width is 45 cm, and the horizontal width is 45 cm. Since the internal volume of the foamed polystyrene box (1) is about 60.75 m ³ , an aqueous solution of about 60.75 Liters (liters) can be placed inside the foamed polystyrene box (1). When converted to counter hit, 4800 foamed polystyrene boxes (1) per counter can be spread, so the amount of water in the aqueous solution is 4800 times that of about 60.75 Liters per liter. 4800 times the aqueous solution of about 60.75 Liter (liter) is about 288 tons. This means that about 288 tons of aqueous solution can be stored in the basement of the desert cultivated land (7) in the area per one piece. Furthermore, for example, when the height of the foamed polystyrene box (1) is doubled from 30 cm to 60 cm, the volume of the foamed polystyrene box (1) is 60 cm in height, 45 cm in length, and 45 cm in width. Therefore, the volume of the Styrofoam box (1) is about 121.5 m ³ , so the 576 ton aqueous solution of about 288 tons, which is twice as large as described above, is used as the cultivated land in the desert. As a result, a pond of about 576 tons is formed in the basement of the cultivated land in the desert (7). Give the water solution necessary for growing and growing plants such as cereals, fruit trees, vegetables, and trees to the field that is the cultivated land in the desert (7), and ensure sufficient water as the aqueous solution. There is an effect that can be.

The purpose is to remove the radioactivity such as cesium contained in the playground or cultivated land.
A radioactive substance such as cesium contained in the athletic field (19) or the cultivated land (19) contaminated with this radioactivity is planted on the surface of the athletic field (19) or the cultivated land (19). Growing plants such as cereals, fruit trees, vegetables, and trees, the plants from the underground contaminated by radiation by transpiration, the plant sucks up radioactive substances such as cesium one after another, Since radioactive materials such as cesium are scattered on the surface of the playground (19) or the cultivated land (19) by transpiration, the radioactive material such as cesium on the surface of the cultivated land (19) contaminated by radioactivity As the value of the radiation dose of a substance grows, the concentration of radioactive substances such as cesium on the surface of the playground (19) or the cultivated land (19) becomes higher. In order to avoid this problem, the polystyrene layer (1) is laid down in the ground of the playground (19) or the cultivated land (19) to cultivate the surface layer of the cultivated land (19) and plants, etc. And transpiration of radioactive substances such as cesium from the ground of the playground (19) or the cultivated land (19) by the transpiration action on the surface of the playground (19) or the cultivated land (19).

The aqueous solution containing water from the desert sand is present on the surface of the desert, on the surface of the desert, and then inside the foamed agricultural box made of polylactic acid (1). Since the moisture contained in the sand (4) rises upward and upward due to capillary action, the polylactic acid foaming agricultural box (1) embedded in the ground and The water that the sand of the desert (4) contains in the middle of the desert surface cultivates, grows, and grows plants such as grains, fruit trees, vegetables, and trees. It is assumed that Example 14 can supply the plant with sufficient water to cause the damage.

For the purpose of greening the desert and cultivating plants such as cereals, fruit trees, vegetables, and trees, 50 cm, or 1 m, or 2 m (hereinafter abbreviated as 1 m, for example) from the ground surface inside the soil (7) ) Shaped object (1) made of vinyl chloride resin or other resin (hereinafter abbreviated as vinyl chloride resin), or vinyl chloride resin at a depth from the ground surface before and after For example, a pipe having a diameter of 30 cm is cut in half, a bowl-shaped object (1) having a diameter of 30 cm, or a corrugated cardboard box (1), or a corrugated cardboard box (1) subjected to water-resistant processing, or A polystyrene foam box made of polystyrene (1), a polylactic acid foamed agricultural box (1), a box made of other materials (1), or a container made of other materials (1) (Hereafter, abbreviated Embed a shaped object (1), or a pipe, box, or container (1) obtained by cutting a part of the pipe in the vertical direction at a depth of about 1 m from the ground surface.

The water content of this desert sand (4) containing water increases to about 80 degrees Celsius during the day, so the water content of the sand (4) on the desert surface is close to 0%. State. When the desert surface sand (4) is in a state where the moisture content of the desert surface sand (4) is close to 0%, and the desert sand (4) is dry, it is buried about 1 m from the surface. The sand (4) flows into the desert sand (4), which is deposited inside the foamed agricultural box made of polylactic acid (1), from the ground via the water pipe (2). In the aqueous solution that has passed through the prevention valve (3) that prevents water from flowing, the desert sand (4) that accumulates inside the foamed agricultural box (1) made of polylactic acid is hydrated.

For example, a saddle-shaped object (1) having a diameter of about 30 cm is embedded at a depth of about 1 m underground in a desert, and a solution (8 ), An artificial waterway or water vein (hereinafter abbreviated as a water vein) is artificially formed around 1 m underground in the desert. When water is sprinkled from the surface of the desert, the aqueous solution evaporates instantaneously, but the aqueous solution is injected to the place around 1 m below the desert via the valve (8) shown in FIG. In this case, since the aqueous solution does not evaporate, the aqueous solution can be supplied to the sand of the desert at about 1 m underground. This aqueous solution containing water from the desert 1m below the desert has a high temperature on the desert surface of around 80 degrees Celsius and is dry, so it is about 1m deep in the desert. The aqueous solution flowing inside the cocoon-shaped object (1) that is buried rises to the surface of the desert, which is the upper direction, by capillary action. When the aqueous solution flowing inside the cocoon-shaped body (1) rises on the surface of the desert due to capillarity, the water vaporizes and the temperature in the desert is high. Will be taken away. Even if the surface temperature of the desert has risen to around 80 degrees Celsius, the underground temperature in the desert will remain at around 35 degrees Celsius. As described above, a very small amount of an aqueous solution is allowed to flow around 1 m below the desert, thereby lowering the temperature of the desert ground and supplying moisture to the desert underground. As a result, we have invented and discovered that even in the desert, it is an optimal land for cultivating crops such as cereals, fruit trees, vegetables and trees. As Example 16, it is possible to cultivate corn, potato, carrot, radish, Chinese cabbage, cabbage, tomato, grape, yam, pineapple, raccoon, garlic, onion, burdock, eucalyptus, and the like.

As a result, we have invented and discovered that even in the desert, it is an optimal land for cultivating crops such as cereals, fruit trees, vegetables and trees. Thus, Example 17 can cultivate watermelon, corn, potato, carrot, Japanese radish, Chinese cabbage, cabbage, tomato, grape, yam, pineapple, raccoon, garlic, onion, burdock, and eucalyptus. .

For the purpose of enabling rice cultivation in the desert, after leveling on the surface of the desert in a flat state, the ridge (11) after forming the ridge (11) on the surface of the desert surface (10) On the surface, a film made of polyethylene (12), or a paper black mulch (12), or a green plastic mulch film (12) made of biodegradable plastic, or other film (12) (hereinafter, Using the film 12 for short, the ridge-shaped object (1) is formed on the surface of the film (12) covering the surface of the ridge (11) after covering the surface of the ridge (11). ), And a sprinkler pipe (2) is installed inside the cocoon-shaped object (1), and then, for example, desert sand (4) is applied to the surface of the cocoon-shaped object (1). On the surface of (1), pile up sand (4) with a height of around 30 cm Embed the bowl-shaped object (1), the film (12), and the sprinkling pipe (2), and pass the aqueous solution into the bowl-shaped body (1) through the valve (9) and the sprinkling pipe (2). Water solution required to cultivate, grow, and grow plants such as grains, fruit trees, vegetables, and trees, which are watered, leaks into the desert basement and does not escape. Using a film (12) at the front and back, covering the entire area of the cultivated land (13), and the water solution sprayed through the water spray pipe (2) leaks into the desert basement and does not leak. At the same time, the purpose is to enable rice cultivation by forming a waterproof wall (14) on the outer peripheral side wall of the cultivated land (13) and pouring the aqueous solution into the cultivated land (13) in a full state. Example 18 is rice cultivation in a desert paddy field.

The biggest reason that plants, grains, fruits, vegetables, and trees cannot grow and grow in the desert is that the salinity of salt contained in the desert sand (4) is There are about 1000PPM. The salinity of the human body is about 300PPM. The salinity contained in the desert sand (4) is, for example, higher in the desert 2m than in the desert 1m. Furthermore, the phenomenon of desert time is that the salinity is much higher in 3m underground than in 2m underground. When an aqueous solution is sprinkled from the surface of the desert surface layer (10) onto the desert sand (4) having a high salinity, the salinity contained in the desert sand (4) is removed from the desert surface layer (10). The more water is sprayed, the more transpiration or evaporation (hereinafter abbreviated to transpiration), the surface of the desert (10), the surface of the desert, the salinity from the desert basement. As the water rises, on the surface of the desert, which is the desert surface layer (10), for example, if the salinity is 5000 PPM to 10,000 PPM and the surface of the desert surface layer (10) is sprinkled, The main reason is that the high salt concentration prevents the plant grains, fruit trees, vegetables and trees from growing and growing in the desert. Date palm is the most salt-tolerant plant on the earth. This date palm can grow and grow even in a desert with a salinity of 1000 PPM. Furthermore, Satsuma mushrooms can grow and grow even at about 800 PPM to 1000 PPM. The salt concentration contained in the sand (4) of the desert surface layer (10) is 1000 PPM. In order to prevent the salinity contained in this desert sand (4) from exceeding 1000PPM, water must be sprayed from the surface of the desert surface (10), and the desert surface (10) The salinity contained in the sand (4) on the surface will be maintained at 1000 PPM. As means for solving this problem, the cocoon-shaped object (1), the foamed polystyrene box (1), or the polylactic acid foamed agricultural box (1) (hereinafter abbreviated, cocoon-shaped) is described below. Using the object (1)), the aqueous solution is sprinkled from the underground, and when the aqueous solution is sucked up to the surface of the desert, which is the surface layer (10) of the desert, by a capillary phenomenon, the bowl-shaped object (1) And only the desert sand (4) that exists in the middle of the desert surface layer (10), and has buried the ridge-shaped object (1), for example, at a point 1m underground in the desert If you want to bury the dredged object (1) and sprinkle the aqueous solution, it will be deeper than the dredged object (1) that is buried 1m underground in the desert, deeper than 1m in the desert, Desert where the sand (4) contains salinity is the desert surface (10) From the raised to the surface, and inventions and discoveries to be able to blocking at the point that embedded trough-shaped object (1). Through this invention and discovery, research and development of agricultural technology that can prevent salt damage with high salinity contained in desert sand (4), the desert can become a granary in the very near future. It is assumed that Example 19 has hidden characteristics.

Grain that is a plant by burying a cocoon-shaped object (1) in the basement around 1 m below the desert and supplying an aqueous solution to the interior of the cocoon-shaped object (1) via a sprinkler pipe (2), When cultivating plants such as fruit trees, vegetables, and trees, desert sand exists between the point about 1 m underground where the cocoon-shaped object (1) is buried and the surface of the desert (10) Grain, fruit trees, vegetables and trees, which are plants containing the salt contained in (4), absorb the salt every year and transpire by transpiration. The salt concentration contained in the desert sand (4), which exists in the middle of (10), decreases year by year. Further, Example 20 shows that there is an advantage that sugar content increases when plants such as Satsuma persimmon, tomato, corn, carrot, pumpkin, pineapple, and mango are cultivated using desert sand (4) having a high salinity as cultivated land. .

Because of the high salinity of the salinity contained in the desert sand (4), for example, in the desert, the salinity contained in the desert sand (4) is as high as around 1000PPM. Because of the salinity, it is the current state of the desert surface layer (10) that only plants as long as date palm can be cultivated and grown as plants. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) in which the plant cannot absorb salt from the desert basement by transpiration, the basement of the desert surface layer (10) is dug down, for example, about 30cm to 1m The purpose of forming a cultivated land (7) by digging the desert basement and arranging the styrofoam boxes (1) of 30cm in height, 45cm in length and 45cm in width in series and in parallel in the desert basement After burying foam filling (17) on all areas of the area to be cultivated land (7) in the basement of the desert, embedding by embedding (17), the surface of the foam foam box (1) A cultivated land (7) can be formed thereon as Example 21.

Because of the high salinity of the salinity contained in the desert sand (4), for example, in the desert, the salinity contained in the desert sand (4) is as high as around 1000PPM. Because of the salinity, it is the current state of the desert surface layer (10) that only plants as long as date palm can be cultivated and grown as plants. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) where the plant cannot absorb salt from the desert basement by transpiration, the surface of the desert surface layer (10) is leveled, for example, the height is Cultivation on the surface of the desert surface layer (10) for the purpose of forming cultivated land (7) by arranging styrofoam boxes (1) of 30 cm in length and 45 cm in width and 45 cm in width in series and in parallel After arranging the polystyrene foam boxes (1) over the entire area of the ground (7), the upper part of the polystyrene foam box (1) is filled with, for example, a height of about 30 cm to 1 m (17) Example 22 shows that the cultivated land (7) can be formed on the surface of the foamed polystyrene box (1).

The purpose is to remove the radioactivity such as cesium contained in the playground or cultivated land.
A radioactive substance such as cesium contained in the athletic field (19) or the cultivated land (19) contaminated with this radioactivity is planted on the surface of the athletic field (19) or the cultivated land (19). Growing plants such as cereals, fruit trees, vegetables, and trees, the plants from the underground contaminated by radiation by transpiration, the plant sucks up radioactive substances such as cesium one after another, Since radioactive materials such as cesium are scattered on the surface of the playground (19) or the cultivated land (19) by transpiration, the radioactive material such as cesium on the surface of the cultivated land (19) contaminated by radioactivity As the value of the radiation dose of a substance grows, the concentration of radioactive substances such as cesium on the surface of the playground (19) or the cultivated land (19) becomes higher. In order to avoid this problem, the polystyrene layer (1) is laid down in the ground of the playground (19) or the cultivated land (19) to cultivate the surface layer of the cultivated land (19) and plants, etc. And transpiration of radioactive substances such as cesium from the ground of the playground (19) or the cultivated land (19) by the transpiration action on the surface of the playground (19) or the cultivated land (19). An object is to provide an athletic field (19) or a cultivated land (19) having a structure that cannot be sucked up on the surface of the athletic field (19) or the cultivated land (19). For the purpose of providing a cultivated land (19) having a structure in which radioactive substances such as cesium cannot be sucked up by the transpiration of the plant from the ground of this playground (19) or the cultivated land (19), for example, a playground (19), or underground of cultivated land (19), 30 cm to 50 cm, digging underground, underground of playground (19) or cultivated land (19), made of polystyrene foam, 3 cm thick, Or a cut plate (1) of a foamed polystyrene plate made of a polystyrene foam having a length x width of around 45 cm x 45 cm, or around 1 m x 1 m, or a height of 10 cm or 30 cm.

A method and apparatus for greening a desert, characterized in that the plant can be supplied with sufficient moisture to allow the plant to grow. For example, a saddle-shaped object (1) having a diameter of about 30 cm is embedded at a depth of about 1 m underground in a desert, and a solution (8 ), An artificial waterway or water vein (hereinafter abbreviated as a water vein) is artificially formed around 1 m underground in the desert. When water is sprinkled from the surface of the desert, the aqueous solution evaporates instantaneously, but the aqueous solution is injected to the place around 1 m below the desert via the valve (8) shown in FIG. In this case, since the aqueous solution does not evaporate, the aqueous solution can be supplied to the sand of the desert at about 1 m underground. This aqueous solution containing water from the desert 1m below the desert has a high temperature on the desert surface of around 80 degrees Celsius and is dry, so it is about 1m deep in the desert. The aqueous solution flowing inside the cocoon-shaped object (1) that is buried rises to the surface of the desert, which is the upper direction, by capillary action. When the aqueous solution flowing inside the cocoon-shaped body (1) rises on the surface of the desert due to capillarity, the water vaporizes and the temperature in the desert is high. Will be taken away. Even if the surface temperature of the desert has risen to around 80 degrees Celsius, the underground temperature in the desert will remain at around 35 degrees Celsius. As described above, a very small amount of an aqueous solution is allowed to flow around 1 m below the desert, thereby lowering the temperature of the desert ground and supplying moisture to the desert underground. As a result, we have invented and discovered that even in the desert, it is an optimal land for cultivating crops such as cereals, fruit trees, vegetables and trees. This greens the desert, characterized by the ability to grow corn, satsuma mushrooms, carrots, radish, Chinese cabbage, cabbage, tomatoes, grapes, yam, pineapple, raccoon, garlic, onion, burdock, and eucalyptus Method and apparatus thereof. For example, a saddle-shaped object (1) having a diameter of about 30 cm is embedded at a depth of about 1 m underground in a desert, and a solution (8 ), An artificial waterway or water vein (hereinafter abbreviated as a water vein) is artificially formed around 1 m underground in the desert. When water is sprinkled from the surface of the desert, the aqueous solution evaporates instantaneously, but the aqueous solution is injected to the place around 1 m below the desert via the valve (8) shown in FIG. In this case, since the aqueous solution does not evaporate, the aqueous solution can be supplied to the sand of the desert at about 1 m underground. This aqueous solution containing water from the desert 1m below the desert has a high temperature on the desert surface of around 80 degrees Celsius and is dry, so it is about 1m deep in the desert. The aqueous solution flowing inside the cocoon-shaped object (1) that is buried rises to the surface of the desert, which is the upper direction, by capillary action. When the aqueous solution flowing inside the cocoon-shaped body (1) rises on the surface of the desert due to capillarity, the water vaporizes and the temperature in the desert is high. Will be taken away. Even if the surface temperature of the desert has risen to around 80 degrees Celsius, the underground temperature in the desert will remain at around 35 degrees Celsius. As described above, a very small amount of an aqueous solution is allowed to flow around 1 m below the desert, thereby lowering the temperature of the desert ground and supplying moisture to the desert underground. As a result, we have invented and discovered that even in the desert, it is an optimal land for cultivating crops such as cereals, fruit trees, vegetables and trees. A desert characterized by its ability to grow watermelon, corn, potato, carrot, Japanese radish, Chinese cabbage, cabbage, tomato, grape, yam, pineapple, raccoon, garlic, onion, burdock, and eucalyptus. Method and apparatus for greening. For the purpose of enabling rice cultivation in the desert, after leveling on the surface of the desert in a flat state, the ridge (11) after forming the ridge (11) on the surface of the desert surface (10) On the surface, a film made of polyethylene (12), or a paper black mulch (12), or a green plastic mulch film (12) made of biodegradable plastic, or other film (12) (hereinafter, Using the film 12 for short, the ridge-shaped object (1) is formed on the surface of the film (12) covering the surface of the ridge (11) after covering the surface of the ridge (11). ), And a sprinkler pipe (2) is installed inside the cocoon-shaped object (1), and then, for example, desert sand (4) is applied to the surface of the cocoon-shaped object (1). On the surface of (1), pile up sand (4) with a height of around 30 cm Embed the bowl-shaped object (1), the film (12), and the sprinkling pipe (2), and pass the aqueous solution into the bowl-shaped body (1) through the valve (9) and the sprinkling pipe (2). Water solution required to cultivate, grow, and grow plants such as grains, fruit trees, vegetables, and trees, which are watered, leaks into the desert basement and does not escape. Using a film (12) at the front and back, covering the entire area of the cultivated land (13), and the water solution sprayed through the water spray pipe (2) leaks into the desert basement and does not leak. At the same time, the purpose is to enable rice cultivation by forming a waterproof wall (14) on the outer peripheral side wall of the cultivated land (13) and pouring the aqueous solution into the cultivated land (13) in a full state. Rice farming in the desert, characterized by rice farming in desert paddy fields Method of enabling, and an apparatus. The biggest reason that plants, grains, fruits, vegetables, and trees cannot grow and grow in the desert is that the salinity of salt contained in the desert sand (4) is There are about 1000PPM. The salinity of the human body is about 300PPM. The salinity contained in the desert sand (4) is, for example, higher in the desert 2m than in the desert 1m. Furthermore, the phenomenon of desert time is that the salinity is much higher in 3m underground than in 2m underground. When an aqueous solution is sprinkled from the surface of the desert surface layer (10) onto the desert sand (4) having a high salinity, the salinity contained in the desert sand (4) is removed from the desert surface layer (10). The more water is sprayed, the more transpiration or evaporation (hereinafter abbreviated to transpiration), the surface of the desert (10), the surface of the desert, the salinity from the desert basement. As the water rises, on the surface of the desert, which is the desert surface layer (10), for example, if the salinity is 5000 PPM to 10,000 PPM and the surface of the desert surface layer (10) is sprinkled, The main reason is that the high salt concentration prevents the plant grains, fruit trees, vegetables and trees from growing and growing in the desert. Date palm is the most salt-tolerant plant on the earth. This date palm can grow and grow even in a desert with a salinity of 1000 PPM. Furthermore, Satsuma mushrooms can grow and grow even at about 800 PPM to 1000 PPM. The salt concentration contained in the sand (4) of the desert surface layer (10) is 1000 PPM. In order to prevent the salinity contained in this desert sand (4) from exceeding 1000PPM, water must be sprayed from the surface of the desert surface (10), and the desert surface (10) The salinity contained in the sand (4) on the surface will be maintained at 1000 PPM. As means for solving this problem, the cocoon-shaped object (1), the foamed polystyrene box (1), or the polylactic acid foamed agricultural box (1) (hereinafter abbreviated, cocoon-shaped) is described below. Using the object (1)), the aqueous solution is sprinkled from the underground, and when the aqueous solution is sucked up to the surface of the desert, which is the surface layer (10) of the desert, by a capillary phenomenon, the bowl-shaped object (1) And only the desert sand (4) that exists in the middle of the desert surface layer (10), and has buried the ridge-shaped object (1), for example, at a point 1m underground in the desert If you want to bury the dredged object (1) and sprinkle the aqueous solution, it will be deeper than the dredged object (1) that is buried 1m underground in the desert, deeper than 1m in the desert, Desert where the sand (4) contains salinity is the desert surface (10) From the raised to the surface, and inventions and discoveries to be able to blocking at the point that embedded trough-shaped object (1). Through this invention and discovery, research and development of agricultural technology that can prevent salt damage with high salinity contained in desert sand (4), the desert can become a granary in the very near future. A method and apparatus for allowing rice cultivation in a desert characterized by having a sexiness. Grain that is a plant by burying a cocoon-shaped object (1) in the basement around 1 m below the desert and supplying an aqueous solution to the interior of the cocoon-shaped object (1) via a sprinkler pipe (2), When cultivating plants such as fruit trees, vegetables, and trees, desert sand exists between the point about 1 m underground where the cocoon-shaped object (1) is buried and the surface of the desert (10) Grain, fruit trees, vegetables and trees, which are plants containing the salt contained in (4), absorb the salt every year and transpire by transpiration. The salt concentration contained in the desert sand (4), which exists in the middle of (10), decreases year by year. In addition, the desert is characterized by having high sugar content when cultivating plants such as Satsuma mash, tomato, corn, carrot, pumpkin, pineapple, and mango using arable land of desert sand (4) as a cultivated land Method and apparatus for enabling rice cultivation in Japan. Because of the high salinity of the salinity contained in the desert sand (4), for example, in the desert, the salinity contained in the desert sand (4) is as high as around 1000PPM. Because of the salinity, it is the current state of the desert surface layer (10) that only plants as long as date palm can be cultivated and grown as plants. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10). The purpose is to provide a cultivated land (7) with no structure. For the purpose of providing a cultivated land (7) in which the plant cannot absorb salt from the desert basement by transpiration, the basement of the desert surface layer (10) is dug down, for example, about 30cm to 1m The purpose of forming a cultivated land (7) by digging the desert basement and arranging the styrofoam boxes (1) of 30cm in height, 45cm in length and 45cm in width in series and in parallel in the desert basement After burying foam filling (17) on all areas of the area to be cultivated land (7) in the basement of the desert, embedding by embedding (17), the surface of the foam foam box (1) A method and apparatus for allowing rice cultivation in a desert, characterized in that a cultivated land (7) can be formed thereon. Because of the high salinity of the salinity contained in the desert sand (4), for example, in the desert, the salinity contained in the desert sand (4) is as high as around 1000PPM. Because of the salinity, it is the current state of the desert surface layer (10) that only plants as long as date palm can be cultivated and grown as plants. Grains, fruit trees, vegetables, which are plants on the surface of the desert surface layer (10), which contains the salt content of the desert sand (4), and the desert sand (4) When plants such as trees are cultivated, the plants are transpirationed, the plants suck up salt from the desert basement, and then scatter the salt on the surface of the desert surface (10) by transpiration. The salinity on the surface of the desert surface (10) increases as the plant grows, so the salinity on the surface of the desert surface (10) becomes higher and higher. On the surface of 10), the inability to grow plants is the biggest disadvantage of the desert. In order to avoid the influence of the salt contained in this desert sand (4), styrofoam boxes (1) are spread on the surface of the desert surface layer (10), and the desert underground and plants are By cultivating the cultivated land (7), which is the desert surface layer (10), the plant can absorb salt from the desert basement by transpiration on the surface of the desert surface layer (10).
