Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for improving the germicidal and insecticidal properties of soil, using natural materials that are friendly to the global environment, and using no chemical pesticides, using smoke and smoke generated when burning charcoal. Things.

[0002]

2. Description of the Related Art Conventionally, modern agricultural methods have been developed in the field of horticultural agriculture, and mass production of agricultural products has been possible. At present, scientific farming methods have been studied and succeeded, but chemical fertilizers,
It is said to be the result of using large amounts of chemical agents such as chemical insecticides. Examples of chemical agents include DDT and B
Pesticides such as HC, methyl bromides, and emulsions such as DDVP have been used. Some of these are already banned or planned to be banned due to toxicity. The reason for this ban is, of course, the obvious toxic one, but in recent years the use of environmental hormones of interest has been banned. Furthermore, it is becoming clear that toxicity is manifested as complex contamination when mixed with even a small amount of a drug contained in a chemical agent. There are some harmless alternatives to the use of toxic chemicals for sterilization and insecticide, albeit with some differences. For example, there is steam disinfection as a means of disinfecting soil, which involves injecting high-temperature and high-pressure steam into the soil, or covering the soil with a sheet or the like, and injecting high-temperature and high-pressure steam between the soil and the sheet. It eliminates various bacteria and pests. In addition, there is a method of sterilization, which utilizes the strong sterilizing power of strongly acidic water among the strongly electrolyzed water generated by electrolyzing salt water obtained by adding salt to water, and is used not only in the agricultural field but also in the medical field. Have been. other,
Bamboo vinegar and bamboo bitumen taken from bamboo charcoal, as well as wood vinegar and wood bitumen taken from bamboo charcoal are called smoke liquor, and are known to have bactericidal and insecticidal properties and also have an effect of promoting crop growth.
There is also an environmentally friendly farming method using plant extracts, enzymes and microorganisms. On the other hand, there is another farming method using charcoal. The method of using charcoal buried in the soil or sprinkling it on the soil has proven to be effective. It has been well-known that a stock solution or a diluent solution can be sprayed to promote germicidal insecticidal and crop growth.

[0003]

As in the prior art described above, a large amount of chemical agents are currently used for sterilization and insecticide. The background of the widespread use of this chemical agent is to cope with mass consumption and to increase and decrease the age of farmers, which is increasing the use of chemical agents along with mechanization. In the current industrial structure, mechanized farming uses a large amount of chemical fertilizers, and some point out that farming is far from natural farming. On the other hand, consumers have been enthusiastic about buying crops that look better than insect-eating crops, which is one of the factors that allows the use of chemical pesticides. Fortunately, however, chemicals such as pesticides that have been used for some time have been banned in recent years as soon as they were determined to be toxic. Furthermore, it has been confirmed that not only the toxicity of the chemical agent but also the endocrine disrupter is contained therein, and suddenly the danger of the chemical agent has been declared by groups and consumers more than before.
As a result, based on the philosophy of protecting your own health,
An increasing number of consumers are looking for pesticide-free vegetables, and in response, pesticide-free cultivation has reached a certain level. As an example,
Consumers have signed a contract with a farmer, and the movement to purchase the pesticide-free crops grown there has been spreading nationwide. However, there are still few pesticide-free crops, and many consumers acknowledge that pesticide-free crops are safe, but that pesticide-free vegetables are expensive and affordable, or a small amount of poison is acceptable. At present, they are still eating high-concentration pesticide vegetables from simple thinking. At present, completely pesticide-free cultivation is very difficult, so we should look for ways to reduce pesticide cultivation as much as possible. Well, the steam sterilization method for soil has recently emerged as an alternative to methyl bromide, which has been completely banned. Since this is a means of sterilizing and killing with high-temperature and high-pressure steam, it is safe without using any chemicals. However, it has been pointed out that this steam sterilizer is a large-scale device, is not inexpensive, and has a problem whether or not it is widely used. This is also the case for strongly acidic water. Strongly acidic water is sterile water having a strong sterilizing power, and although its sterilizing effect is recognized, its production cost is very low, but its complete set is expensive, so it has not been widely used. In view of the above, the emergence of fungicides and insecticides that are environmentally friendly because they can be mass-produced inexpensively without using chemical agents that have a negative effect on human bodies or the environment or that may be a concern. Therefore, he focused on the charcoal that has been used for a long time, and also focused on the smoked liquid that can be formed when the charcoal is burned. This is because bamboo vinegar and bamboo bitumen (chikuleki) collected from bamboo, and wood vinegar and wood bitumen collected from wood have been spotlighted as environmentally friendly fungicides that do not use any chemical agents. However, each liquid has a drawback that only a small amount can be collected from bamboo or wood, and it cannot be supplied in a sufficient amount for large-scale farming. Here, the bamboo vinegar (wood vinegar) liquid is a liquid obtained by cooling smoke generated when burning charcoal, and the bamboo bitumen is a liquid that accumulates at the bottom of a kiln that is discharged when burning bamboo charcoal. It has been found that various substances can be extracted from charcoal, whether bamboo or wood. In the present invention, bamboo bitumen, which has not been noticed until now, has the same bactericidal activity as bamboo vinegar when speaking of bamboo,
In China, it has been widely used as an internal medicine or topical medicine for illness since 3,000 years ago. Therefore, it is important to actively use this tabasheer together with wood bite. It is also important to develop new means of using the smoke itself. In the past, smoke was either untreated and released into the atmosphere, or at best used only to extract bamboo vinegar and wood vinegar from smoke. Even without effective use of smoke, it is considered problematic to emit untreated smoke from the viewpoint of air quality conservation. Since smoke contains many components similar to the smoke liquid, it has been a problem to effectively use the smoke itself.

[0004]

Means for Solving the Problems In order to solve the above problems, smoke emitted from a charcoal kiln contains components and minerals having bactericidal and insecticidal properties. , And soil improvement. In the soil, it does not immediately penetrate into the soil, so it is necessary to continue spraying for a long time to obtain an effect. In a closed state, the effect is faster, so that it is sufficient to cover the soil with a sheet or the like and steam the smoke. Even when smoking a crop or plant, the effect is fast if it is a closed space, but if it is not possible, smoke should be applied so that the smoke is directly applied. By doing so, the fungicidal insect repellent and growth promoting effects appear on crops and plants, and various types can recover from the disease, and grow vigorously, so that the color and luster are improved and, in fact, the quality is actually high. Spraying the undiluted solution or the smoked liquid as a diluting solution on soil or crops exerts effects such as sterilizing insects, improving soil, and promoting crop growth. However, in liquid form, it is effective only on surfaces that are sprayed and wet with the liquid. Since the effect is limited in liquid,
Use by vaporizing. When the smoke liquid is vaporized, the vapor of the vaporized smoke liquid flows to the rear surface, so that the medicinal component can be spread over the entire surface.

[0005]

1 is an overall view of a charcoal kiln according to an embodiment. A canopy (2) having a curved surface is placed and fixed on a metal body (1) to form a highly sealed exterior, and the interior is treated with a castable (43) as a heat-insulating material. Then, an outlet (3) for charging the raw material into the body (1) and discharging coal, and a firing port (4) at the upper part are provided. The heating port (4) may have a structure in which hot air is blown horizontally. However, since the canopy (2) has a curved surface, the hot air flows well along the curved surface. Therefore, the heating port (4) is inclined. In addition, an inclined flame guide portion (5) is provided at the heating port (4) to guide the flame or hot air of the burner (6) attached to the tip to the heating port (4). An air blower (7) for control is provided. A smoke outlet (8) is provided at the lowermost part of the body (1). The position of the smoke outlet (8) is for collecting the liquid from the lower liquid sampling port (9) provided near the smoke exhaust port (8) because bamboo bitumen and wood bitumen accumulate at the bottom. However, if an independent lower sampling port (9) is provided without using the smoke outlet (8), the smoke outlet (8) does not need to be at the bottom, but from the viewpoint of combustion efficiency, The mouth (8) must be at the bottom. A lower smoke stack (10) extending upward from the smoke stack (8) is attached to the smoke stack (8), and the atmosphere is temporarily opened at the outlet. Then, a smoke collecting section (11) having a large opening area is connected to an upper portion of the outlet of the lower smoke stack (10), and an upper smoke stack (12) connected to the smoke collecting section (11). A cooling device (13) for cooling smoke is provided in the middle of the upper smoke stack (12). The cooling device (13) may be air-cooled, water-cooled, or another type. The smoke collecting section (11) is provided with a bend (14) for receiving bamboo vinegar (wood vinegar) liquid from the cooled smoke, and further provided with an upper liquid sampling port (15) for collecting the liquid. When the cooled or cooling device (13) is not used, the smoke removing device (1) that quickly exhausts the uncooled smoke is used.
9) An exhaust blower (16) is provided. The smoke discharged from the exhaust blower (16) reaches a branch (17). The smoke is directed on the one hand to a smoke outlet (18) and on the other hand to a cooling device (13). As described above, the reason why the smoke emitted from the smoke outlet (8) is once released to the atmosphere at the outlet of the lower smoke stack (10) is that the smoke emitted from the smoke outlet (8) is hot. For primary cooling and when the smoke outlet (8) is directly connected to the exhaust blower (16), the exhaust blower (16)
This is because the combustion becomes unstable due to the negative pressure due to, and it is desired to suction at atmospheric pressure. The above is the structure of the charcoal kiln (20). The smoke from the smoke outlet (18) is used for smoking, and the collected bamboo vinegar (wood vinegar) liquid and bamboo (wood) bitumen are sprayed or vaporized to smoke. Smoke.

[0006]

FIG. 2 shows a first embodiment of the present invention. In this embodiment, smoke (21) emitted from a charcoal kiln (20) is discharged into a horticultural house (22) to sterilize and kill soil in the soil and improve the soil. Smoke outlet of charcoal kiln (20) (1
8) Connect a smoke pipe (24) and a smoke hose (25) to
Smoke (21) inside garden house (22) which is an enclosed space
Release. If the horticultural house (22) is in a completely closed state, the smoke (21) does not enter with a balance of the atmospheric pressure inside and outside the horticultural house (22), so it is preferable to provide a small exhaust hole to adjust the pressure. However, since there is always a gap in the horticultural house (22) at the site, it may not actually be necessary. The smoke (21) is released into the horticultural house (22), and it is necessary to keep the horticultural house (22) filled with the smoke (21) for 2-3 days. Although the smoke (21) has a bactericidal and insecticidal effect, it is not a kind of instant killing or insecticide like a powerful medicine, so it is necessary to keep the smoke (21) full for a few days. Even if methyl bromide is used as a chemical for soil sterilization, it is covered with a vinyl sheet or the like and steamed for 2-3 days after introduction. Since the smoke (21) emitted from the charcoal kiln (20) has a high specific gravity, even if it is discharged into the horticultural house (22), it does not rise to the ceiling but floats below. When the smoke (21) is released one after another, the concentration below the top is slightly higher than that above and comes into good contact with the soil (23), so that the bactericidal and insecticidal effect is enhanced. After several days of smoking, they gradually enter the soil (23), where sterilization and insecticide and soil improvement are carried out.

A second embodiment of the present invention will be described with reference to FIG. In this embodiment, smoke (21) emitted from a charcoal kiln (20) is discharged into a horticultural house (22) to sterilize or kill insects. A smoke pipe (24) and a smoke hose (25) are connected to a smoke outlet (18) of the charcoal kiln (20) to discharge smoke (21) into the horticultural house (22). Charcoal kiln (20)
Since the smoke (21) coming out of the house has a high specific gravity, even if it is released into the garden house (22), it does not rise to the ceiling but drifts below. When the smoke (21) is released one after another, the concentration below the top becomes slightly higher than that above, and the crop (26) can be sufficiently smoked. In this way, various bacteria adhering to the crop (26) are killed, and pests are controlled to improve the soil.
6) help the growth. At the same time, smoke (2)
Since 1) is in contact, there is also an effect of disinfecting and killing the soil (23).

A third embodiment of the present invention will be described with reference to FIG. In this embodiment, smoke (21) emitted from a charcoal kiln (20) is sprayed onto soil (23) to sterilize or kill the soil (23). A smoke pipe (24) and a smoke hose (25) are connected to the smoke outlet (18) of the charcoal kiln (20), and the soil (2)
3) and smoke (21) between the caps spreading on the soil (23)
And sterilization of the soil (23).
Use a sheet (27) as a cover easily. However, the covering is not limited to the sheet (27) but may be any as long as it spreads on the soil (23). Unfold the sheet (27) on the soil (23),
The location is not limited to farmland because the method guides the smoke (21) between the sheet and the sheet (27). Seat (2
The wider the 7), the more difficult it is for smoke (21) to enter.
Provide space in some places or exhaust holes (28) to create smoke (2
Means for releasing 1) may be provided. This effect is similar to that of the first embodiment.

A fourth embodiment of the present invention will be described with reference to FIG. In this embodiment, the smoke (21) emitted from the charcoal kiln (20) is discharged into the soil (23) to sterilize or kill the insects in the soil (23). A smoke hose (25) is connected to the smoke outlet (18) of the charcoal kiln (20), and smoke (21) is sent to a perforated pipe (29) buried in the soil (23) to sterilize the soil (23). It is a method of performing. Perforated pipe (2) for burying smoke (21)
Since the smoke (21) is injected into the soil from the hole (44) of the perforated pipe (29) by guiding to 9), the sterilizing and insecticidal effect in the soil is high. Also, without embedding the perforated pipe (29), the soil (2
3) By piping above, it is possible to intensively sterilize and kill insects at desired locations.

A fifth embodiment of the present invention will be described with reference to FIG. The present embodiment is a method in which the charcoal kiln (20) is mounted on a moving vehicle (30) and smokes while moving. Moving vehicle (3
0) is equipped with a charcoal kiln (20), a smoke pipe (24) is connected to a smoke outlet (18) of the charcoal kiln (20), and a soil (23).
In the case of germicidal insecticide or soil improvement, the smoke (21) may be sprayed toward the soil (23), and the crop (26) may be sprayed so as to hit the crop (26). Soil (23)
May be sprayed on the surface of the soil (23), but the soil (23) is agitated and well
The effect is high if the smoke (21) can be scratched. As a matter of fact, when the smoke (21) is vigorously sprayed onto the rotating claw (31) of the cultivator while plowing with the cultivator, the soil (2
3) and smoke (21) become familiar, and the bactericidal effect and the like increase.

A sixth embodiment will be described with reference to FIG. Although the enclosed space in the above embodiment was a horticultural house, various places may be considered where sterilization and insecticide are required. As an example,
The means of the present invention is very good because livestock stables are rich in germs and insects and are treated with chemical agents. It is also effective for closed rooms such as warehouses. In a general house (45), apart from smoking indoors, it can be used for termite control under the floor (46). These are completely harmless, simply by introducing the smoke (21) there from the smoke hose (25).

A seventh embodiment will be described with reference to FIG. Smoking is not limited to a closed space, but may be performed in an open space. The present embodiment is a method in which smoke (21) is sent by a smoke hose (25), and is sprayed on a crop (26) or an object to smoke.

When the charcoal is burned, the smoke (21) emitted from the charcoal kiln (20) is cooled, so that bamboo vinegar is obtained from bamboo and wood vinegar is obtained from wood. At the same time, bamboo bamboo is obtained at the bottom of the charcoal kiln (20) when bamboo is burned, and wood asphalt is obtained at the time of wood baking. These liquids are rich in various organic substances and minerals, and have fungicidal and insecticidal effects, soil improvement, and nutrient replenishment for crops (26). It was used by spraying on crops (26), but in the mist state of spraying, the effect was only on the sprayed surface, and was not effective on the surface not sprayed. When the vapor is in the gaseous state, the effect can be obtained because the vapor can go around the back of the leaf.
The vaporization injection device of the eighth embodiment will be described with reference to FIG. Torso (3
A nozzle (33) is provided at the end of 2), a liquid reservoir (34) is provided near the base of the nozzle (33), an electromagnetic valve (35) is provided immediately below the liquid reservoir (34), and a needle ( 3

The charcoal kiln of the present invention is made of iron and is small in size, so that the transfer is easy. In addition, the interior of the combustion furnace uses castable high-grade heat-insulating agent, which is also used in incinerators, so its durability and heat resistance are excellent. If the amount of air blown by the blower is adjusted, the furnace can reach around 1,300 degrees Celsius. The internal temperature can be raised. Since the furnace temperature was extremely high, it was possible to easily bake charcoal with the same hardness as Bincho charcoal. Naturally, a burner is used to ignite raw materials such as bamboo and wood, but if a kerosene burner is used, the bamboo can be turned into a self-burning state in just 10 minutes and turned into charcoal in one day. However, reducing the amount of air and prolonging the burning time will result in higher quality bamboo charcoal. In the case of wood, the wood becomes self-burning in less than one hour and becomes charcoal in about two days. As is well known, when the finished charcoal is spread on soil, it becomes a soil improver made of a natural material. Unlike a chemical fertilizer, the soil improver is friendly to the global environment. When charcoal is scattered in the soil or soil, it releases minerals contained in the charcoal and helps microorganisms work. As can be seen by enlarging the cross section of charcoal, charcoal is large and bamboo charcoal has many small pores. The microorganisms inhabit and activate the pores, thereby promoting the absorption of nutrients into the crop, and as a result, the effect of promoting the growth of the crop appears. Bamboo vinegar, bamboo bitumen, wood vinegar, and smoked wood bitumen generally include organic acids such as acetic acid and propionic acid, alcohols such as methanol and ethanol, phenols such as cresol and guaiacol, levoglucosan and valeric acid. A large amount of neutral substances such as esters are contained, and the bactericidal and insecticidal effect is mainly effected by phenols of acetic acid and cresol, and the promotion of crop growth is effected by neutral substances. In addition, the contained esters have the function of increasing chlorophyll, greening the leaves, and having a growth promoting effect. A liquid substantially the same as the diluted liquid of the smoke liquid can be taken from the smoke elimination device, so that the liquid can be sprayed, and the smoke can be effectively used. Since the smoking liquid contains a lot of minerals in addition to the above components, it has a function of assisting the growth of useful microorganisms such as Bacillus and radioactive bacteria, and can improve soil. In addition, since the smoke liquid is strongly acidic and contains alcohols, the pesticide is easily dissolved and easily penetrated into the crop, and a pesticide-reducing effect is also produced. or,
It was found that including smoke in charcoal increased the synergistic effect. On the agricultural side, it is common to use a smoked liquid as it is or diluted and sprayed on soil or crops, which has been very effective. On the other hand, as a medicinal effect, there is an ancient document that describes that tabasheer has a medicinal effect in China since 3,000 years ago and has been used as an internal medicine and a paint. In China, the benefits of smoke have been known for more than 3,000 years. Spraying the smoking liquid also has a deodorizing effect. The smoke has a unique smell,
When sprayed on livestock manure, it can decompose ammonia and eliminate odors. In this way, the production of charcoal and smoke that has a wonderful function has become possible in a small and movable metal kiln.

Conventionally, in charcoal baking, smoke is used only for collecting the smoke, and the smoke after the smoke is collected is released to the atmosphere. However, this smoke contains many active ingredients of the smoke. You should use it all. The reason for this is
Emission of combustion gases into the atmosphere means air pollution,
Because of the current social situation, it is regarded as a source of pollution, so it is necessary to refrain from exhausting smoke into the atmosphere indiscriminately. Therefore, if the smoke exhaust component is adsorbed and collected by a filter or activated carbon, a route to reuse the adsorbed component can be opened. In the present embodiment, as a smoke countermeasure, a method of purifying smoke exhaust by dipping it into water was adopted. The reason for this is that when various kinds of components in the flue gas are dissolved in water, they are the same as the diluted liquid of the smoke liquid, and may be used for spraying. This has the advantage that the components can be sufficiently extracted from the flue gas and the flue gas is purified, so that it can be evaluated from the viewpoint of effective use of resources and environmental conservation.

Now, regarding the smoke, in the charcoal kiln of the present invention,
A branch is made downstream of the smoke exhaust blower, and one of them is guided to the above-mentioned smoke eliminating device, where the smoke is eliminated. During the smoke eliminating process, the smoke outlet is closed with a lid. However, if the branch is a switching valve, there is no need to cover the smoke outlet. On the other hand, the smoke guided from the branch or switching valve to the smoke outlet can be used for smoking work. As an actual example of use, if a smoke pipe or smoke hose is connected to the smoke outlet and released into a closed room such as a horticultural house, the smoke reaches the soil and crops, sterilization, insecticide, soil improvement,
It has a growth promoting effect. Also, introducing smoke under a wide sheet spread on the soil has a sterilizing and insecticidal effect on the soil,
It is a safe means without using chemical agents. Since smoke is as acidic as smoke, the smoke pipe and the smoke hose are preferably made of an acid- and corrosion-resistant material. The reason for this is to prevent corrosion of the contact metal part and to prevent the accompanying deterioration of smoke.

Similar to bamboo vinegar, bamboo asphalt, wood vinegar and smoke of wood asphalt, smoke has the same effect because it contains the same components.
However, there is a difference in the effect due to the difference in density between the liquid and the gas. For example, in the case of spraying a smoking liquid and in the case of smoking, the smoking effect is clearly superior to the smoking effect. But don't miss the point where smoke is better than smoke. Smoke is a gas,
Since smoke liquid is a liquid, it should take advantage of the fact that smoke molecules are overwhelmingly small at each molecular level. In other words, the method of using the smoking liquid is to spray it with a liquid or spray it in a mist with a sprayer. Spraying with a nebulizer sprays the liquid in a small mist, but has the disadvantage that it has an effect on the surface of the mist-applied crop and has no effect on the surface without mist. On the other hand, since smoke is a gas, it has the feature that it goes around even behind the leaves. Further, even in the case of a sprayer in which the smoke is reduced and sprayed, since the range in which the mist reaches depends on the spraying ability of the sprayer, it does not reach far away. However, since smoke is a gas, it has the characteristic of self-dispersing more and more when injected at a single point. The smoke gas molecules are naturally diffused with the Brownian motion of the air molecules. Therefore, there is no need to prepare large-scale equipment, such as horticultural greenhouses, livestock stables,
Active ingredients can be delivered to every corner of the warehouse. In general households, it is also effective in controlling termites under the floor. Also, smoking in an open space instead of a closed space has a wide range of effects. Smoke on plants has fungicidal and insecticidal and growth promoting effects.

In the eighth embodiment, the present embodiment is intended to vaporize bamboo vinegar, bamboo bitumen, wood vinegar, and the smoke of wooden bitumen, and to send steam using a fan. As described in the effect of smoking, if you vaporize the smoke liquid and make it a gas, it can go around on the back or in a deep place compared to a fine liquid, that is, a mist, so even if you spray it with a sprayer, Can also have an effect. In addition, although the effect of smoking is explained, since it is not liquid, it cannot be expected to be as effective as a liquid sprayer, but it is effective when sterilizing and killing slowly over a long period of time. Since the apparatus itself can be reduced in size, it can be lightly worked. Since the smoke liquid can always be produced by burning charcoal, it can be used in combination with smoking in consideration of the use situation.
Although not considered in the present embodiment, the heat generated during charcoal burning can be effectively used as a heat source for various heating. According to the present invention, charcoal, smoke, and smoke, which are generated from bamboo and wood, can be used without wasting them at all. Since there is no waste at all, this is a breakthrough in terms of effective use of resources and environmental conservation. Naturally, since the raw materials are bamboo and wood, it is an ecologically friendly means to open the way for pesticide-free cultivation.
