Description

  The present invention relates to a greening device and a greening method using a water-absorbing material suitable for greening dry soil such as deserts.

Sand in deserts and the like has a very low function of retaining moisture as compared with general soil, so that plants are difficult to grow. Therefore, conventionally, in order to green the desert and the like, it has been proposed to retain moisture in the soil using a water-absorbing material. For example, the seedling pot is made of a water-absorbing material, and in the desert area, the pot itself is planted together with the seedling so that moisture can be retained around the seedling. In this way, plants can be grown locally even in an environment such as a desert. In addition to the planting method using the pot, a method of providing a water retaining function to the entire soil by laying a water-absorbing film on the surface of the desert is also proposed.

  However, in the planting apparatus using this pot, since it is necessary to embed the pot in the soil for each seedling, there is a problem that a lot of labor is required for the planting operation.

  Moreover, in the method of laying a water-absorbing film on the soil, there is a problem that the water-absorbing material is deteriorated early by sunlight and the water retention function is lowered in a short period of time. Furthermore, in order to carry out desert greening over a wide area, it is necessary to germinate a large amount of seeds and grow the plants at an early stage. In this case, the film on the desert surface becomes an obstacle, and the seeds for greening on the ground surface. There is a problem that it is difficult to stably hold the fertilizer.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a greening device and a greening method that enable soil greening in a desert or the like to be easily and effectively using a water-absorbing material. .

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to perform greening of soil efficiently, shortening the time required for construction work.

  Hereinafter, examples of embodiments of the present invention will be described in detail with reference to the drawings.

  1A and 1B show an appearance and an overall cross section of a greening device 1 according to an embodiment of the present invention. The tree planting apparatus 1 is installed on a water-absorbing polymer 10, a water-permeable bag portion 20 that accommodates the water-absorbing polymer 10, and at least a part of the outer surface 20 </ b> A (here, the upper surface). The water-permeable cover part 30 and the greening nutrient 40 that replenishes nutrients for growing plants are provided.

  The water permeable bag 20 is formed by overlapping two linen fabrics 22 and 24 formed by weaving natural hemp fibers and sewing the outer periphery with a thread 26 so that moisture can pass therethrough. It has become. The water permeable cover 30 is also made of linen similar to the linen 22, 24, and is sewn together with the water permeable bag 20 by a thread 26. As a result, the holding space 34 is secured between the outer surface 20 </ b> A of the water permeable bag 20 and the water permeable cover 30. In addition, since the water-permeable bag part 20 and the water-permeable cover part 30 can be finally biodegraded and can return to soil by utilizing a hemp fiber, an environmental load is reduced.

  The water-absorbing polymer 10 shown in FIG. 2 is a powder or granular super-water-absorbing water retaining agent, and is stored in advance in a water-soluble paper bag. Thus, if it puts in a paper bag, it can prevent that powder disperses in an unused stage. The water-absorbing polymer 10 has a pH of 6 to 7 so as not to adversely affect plants, and absorbs moisture to form a gel and retains moisture for a long time. For example, water-absorbing polymers that can be used include polyvinyl alcohol-based water-absorbing polymers, granulated polyurethane, nonionic water-absorbing polymers, and highly polymerized acrylic acid polymers. In order to reduce the environmental load, the water-absorbing polymer is composed of a biodegradable material.

  As shown in FIG. 3, the greening nutrient 40 accommodated in the holding space 34 is solidified in a sheet shape. This greening nutrient 40 functions as a so-called fertilizer, and is obtained by dissolving a chemical fertilizer powder such as phosphorus or potassium, fish meal or the like in a binder to form a paste, and drying the paste in a sheet shape. . Plant seeds 42 are mixed in the inside of the greening nutrient 40 and solidified together with other fertilizer powders. Various plant seeds 42 can be used. For example, grass can be selected.

  As shown in an enlarged view in FIG. 4, a plurality of belt-like fixing cloths 46 are arranged on the surface of the sheet-like green nutrient 40, and the greening nutrient 40 is applied to the fixing cloth 46. The water-permeable bag portion 20 is sewn. Therefore, the greening nutrient 40 is sandwiched between the fixed cloth 46 and the water-permeable bag portion 20 and is not partially biased by restricting movement. Since the plant seeds 42 are also dispersed in the greening nutrient 40, the plant seeds 42 are also arranged so as to spread over the entire holding space 34. Here, the plant seeds 42 are mixed inside the greening nutrient 40, but other than that, it is of course possible to prepare a layer separately from the greening nutrient 20 and arrange the plant seeds 42 there. I do not care.

  Next, a method for using the greening device 1 will be described.

  First, the greening device 1 is immersed in water in a water tank so that the water-absorbing polymer 10 absorbs water. Since the water-absorbing polymer 10 absorbs moisture and expands, the greening device 1 is swollen as shown in FIG. 5 and has a thickness of about 20 to 30 cm. Since the sheet-shaped greening nutrient 40 is sewn to the water-permeable bag part 20, it slides around the swelled water-permeable cover part 30 (that is, a low part) inside the holding space 34, There is no partial bias.

  After preparing a plurality of tree planting apparatuses 1 that have sufficiently absorbed moisture, as shown in FIG. 6, holes are dug in the desert 70 and filled with a certain interval. At this time, the water-permeable cover 30 side of the greening device 1 is set to the ground surface side (that is, the upper side). Specifically, the greening device 1 is buried in the ground so that the water-permeable cover 30 is located at a depth of about 3 cm to 5 cm from the ground surface. In addition, plants 72 (seed corn seeds) such as seeds and seedlings are planted between the plurality of greening devices 1.

  As a result, as shown in FIG. 7, since the water-absorbing polymer 10 holds a large amount of water, the seed 42 is appropriately replenished by appropriately supplying water to the seed 42 mixed in the greening nutrient 40. Germinate. The sprout 44 can pass through the water-permeable cover 30 and jump to the surface of the earth, and can quickly grow using the nutrients of the greening nutrient 40. In addition, the sand around the greening device 1 becomes damp under the influence of the water-absorbing polymer 10, so that moisture is also provided to the plant 72 planted on the desert side so that it can grow. As a result, the entire area in which the greening device 1 is embedded is greened in a short period of time. Depending on the weather, temperature, etc., when the plant seed 42 is turf, it germinates in about 7 days, and after 10 days, new shoots appear on the surface. The surrounding corn can be germinated and grown as usual even in desert areas.

  According to the greening device 1 of the present embodiment, since the nutrient 40 and the seed 42 are packaged, the nutrients and plant seeds suitable for the target area can be selected in advance and enclosed in the greening device 1. Greening work can be performed very easily in areas such as deserts. In particular, since the greening device 1 is configured in a bag shape, transportation and construction can be completed in a short time. Furthermore, since the water-absorbing polymer 10 which is easily deteriorated by sunlight or the like can be covered with the water-permeable bag portion 20 or the like, and the entire greening device 1 can be buried in the ground, the moisture retention of the water-absorbing polymer 10 over a long period Ability can be maintained.

  In addition, according to the present planting apparatus 1, the greening nutrient 40 accommodated in the holding space 34 can appropriately absorb moisture from the water-absorbing polymer 10 and supply the plant seeds 42 with nutrients together with the moisture. It has become. Moreover, since the plant seeds 42 are mixed and disposed in the entire surface of the greening device 1 by being mixed with the greening nutrient 40 solidified in a sheet shape, the amount of plant seeds 42 required is reduced. This makes it possible to use water and nutrients effectively.

  In particular, since the greening nutrient 40 and the plant seeds 42 on the outer surface 20A side of the water-permeable bag 20 are arranged in the greening device 1 instead of the water-absorbing polymer 10, unnecessary outflow of nutrients is avoided. Is done. Specifically, since the situation where the nutrients of the greening nutrient 40 are absorbed by the water-absorbing polymer 10 can be reduced, the nutrient concentration in the holding space 34 can be increased. Therefore, the plant seed 42 can grow in a sufficient nutrient environment, and the greening rate can be increased.

  Similarly, since the water-absorbing polymer 10 side is the ground side and the holding space 32 in which the seeds 42 are accommodated can be brought closer to the ground surface side, buds are prevented from being buried in the water-absorbing polymer 10. it can. That is, even though the greening device 1 is packaged, the water-absorbing polymer 10 is disposed on the lower side (underground side) so that moisture can be supplied to the plant disposed on the upper side.

  Although not particularly shown in the drawings and the like, it is preferable that the greening apparatus 1 further has an air-blocking bag that covers the water-permeable bag portion 20 and the water-permeable cover 30 and is isolated from the outside air. In this way, the entire planting device 1 is housed in an air-blocking bag, and the entire interior is maintained in a low-pressure space (for example, low oxygen and low carbon dioxide state), so that the natural germination of the plant seeds 42 during storage and transportation is possible. Is prevented. Moreover, since the water-absorbing polymer 10 can function as a desiccant due to the outside air isolating function of the air-blocking bag, moisture such as the greening nutrient 40 is suppressed and long-term storage becomes possible. Further, if a part of the air blocking bag is broken and water is poured into the air blocking bag by a hose or the like, the air blocking bag itself becomes a container for the water absorbent polymer 10 to absorb moisture, and the desert area. However, the hydration work can be effectively performed. Furthermore, by setting the size of the air-blocking bag to such an extent that it can be broken by the expansion of the water-absorbing polymer 10, it can be used as it is buried in the ground. In order to reduce the burden on the environment, it is desirable that the air blocking bag is made of a biodegradable material.

  Moreover, in this embodiment, although shown only when the hemp fiber was used for the water-permeable bag part and the water-permeable cover, this invention is not limited to it. For example, various materials such as cloth woven with cotton fibers other than hemp, non-woven fabric, and biodegradable vinyl with holes can be used, but from the viewpoint of environmental impact, biodegradable materials are used. It is desirable to do. Moreover, although the case where the sheet-like water-permeable cover is disposed on one surface of the bag-like water-permeable bag portion is shown here, the present invention is not limited to this, and for convenience, the entire bag is made to have a double structure. And it is also possible to make the holding space of the greening nutrient between the inner bag and the outer bag.

  Furthermore, in this embodiment, it was shown only when a water-absorbing polymer was used to retain moisture. However, the present invention is not limited thereto, and any other material that can retain moisture and provide it to plants can be used. A material may be used. Moreover, although the case where the seed is arrange | positioned in the holding | maintenance space was shown in this invention, this invention is not limited to it, You may make it sow a seed to the exterior of a greening apparatus suitably.

  In addition, the greening apparatus of this invention is not limited to above-described embodiment, Of course, various changes can be added within the range which does not deviate from the summary of this invention.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to shorten time required for construction work, it becomes possible to perform greening of soil efficiently. This greening device can be used in various places other than desert areas.
