【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a tubular packing body main body in which a net-like sheet having a large number of pores 2 made of polyethylene fiber is formed into a tubular shape as a material for distributing pores, and inside the tubular packing body main body 1. An obsidian pearlite 3 and a fertilizer 4 are stored, and both ends 1a and 1b of the tubular body 1 are closed by a string 5.

The obsidian-based pearlite 3 will be described in detail. It is manufactured by firing obsidian at a temperature of 800 ° C. to 1000 ° C. and has a larger particle size than the holes 2 of the cylindrical body 1 having numerous independent pores. It is an expanded particle.

Incidentally, what is obtained by the ratio of the bulk specific gravity of the expanded particles and the specific gravity of the obsidian before expansion is called the expansion ratio (calculations are shown in the following formulas (1) and (2)). It is a numerical value showing an increase in the pore volume of. The numerical value is preferably 10.6 or more.

[0017]

[Equation 1] The dry weight is the weight when an appropriate amount of obsidian perlite particles is dried at 110 ° C. The saturated water weight is the weight when the obsidian pearlite particles reach the water absorption limit. The underwater weight is the weight in water when the obsidian pearlite particles reach the water absorption limit. The constant 2.35 is an effective numerical value of the specific gravity of obsidian.

Further, the ratio of the volume of the open pores to the total volume of the expanded particles (including the open / sealed pores) is called the open porosity (the calculation formula is shown in the following formula (3)), and the numerical value is , 66.8% or more is preferable.

[Equation 2]

The expanded particles of the obsidian-based pearlite 3 exhibit the highest oxygen supply capacity when the product of the expansion ratio and the open porosity is in the range of 751 to 1084. It has been proved by the results of repeated experiments by other people. That is, the above range is excellent in air permeability and water retention and contributes most to root rot prevention and growth promotion of plants.

Further, the fertilizer 4 is composed of well-known compost, chemical fertilizer, excrement, etc., and is solidified into particles having a size that does not flow out from the hole 2 of the tubular packing body 1 during transportation. It is a thing.

A case in which the obsidian-based pearlite tubular body 10 having the above-mentioned structure is used for planting work on a thin soil reclaimed land made of clay or the like will be described below with reference to FIG.

Reference numeral 6 denotes a planting hole excavated in the constructed land, and an obsidian-based pearlite 3 is laid on the bottom portion 6a to form a lower layer 7. Incidentally, instead of the obsidian pearlite 3, crushed stone, crushed stone or the like may be laid.

Then, seedlings 8 are planted with one end 1a of the obsidian-based pearlite tubular packing 10 according to the present invention buried in the lower layer 7 and the other end 1b exposed on the ground surface, and fertilized soil 9 is used. Backfill. However, the number of obsidian-based pearlite tube packing bodies 10 to be buried is arbitrary.

By performing the construction in this way, the air is fed into the planting hole 6 from the other end 1b of the obsidian-based pearlite tubular body 10 through the obsidian-based pearlite 3. The root rot of the seedling 8 can be prevented. Further, when water is introduced from the other end 1b of the obsidian-based pearlite tube packing 10 exposed on the surface of the earth, the water is retained in the obsidian-based pearlite 3 and excess water flows to the lower end layer 7 on one end 1a side. Therefore, the obsidian pearlite 3 retains the required water, and the excess water is drained to the lower layer 7, so that excess water does not remain in the root portion of the seedling 8 and root rot does not occur.

The obsidian-based pearlite cylinder 10 contains not only the obsidian-based pearlite 3 but also the fertilizer 4, so that the fertilizer 4 flows out as the seedling 8 grows. That is, since the obsidian-based pearlite 3 appropriately suppresses the outflow of the fertilizer 4, it becomes possible to supply the fertilizer 4 at least until the seedling 8 becomes an adult tree.

In addition, since air is constantly sent in as described above, soil animals such as earthworms and larvae can be activated, and organic matter is decomposed by microorganisms such as aerobic organisms to form a new ecosystem. That is, the surrounding thin soil is gradually improved.

In the above-mentioned embodiment, the tubular body 1 is made of polyethylene fiber, but its material is not limited to polyethylene fiber, and other synthetic resin fibers such as polyvinyl chloride, polystyrene, polypropylene, etc. It may be a plastic synthetic resin or nylon. Further, in the above-mentioned embodiment, the tubular body 1 is formed of a tubular mesh sheet, but is not limited to the mesh sheet, and a hard / soft plastic or innumerable holes 2 may be formed. You may use what was formed in the tubular shape with a metal thin plate etc. The point is that any material having a hole and capable of accommodating obsidian-based pearlite inside may be used as the material for providing the dispersion holes.

In addition to the materials described above, biodegradable resin, woven fabric, wood, or the like can be used as the material of the tubular packing body 1. If the body 1 of the tubular body is formed from materials that are decomposed in the natural world, nutrients for soil animals and microorganisms will be supplied to the lean land, and this will have the effect of activating those activities. .

Further, in the above-described embodiment, the tubular body 1 has a structure in which both ends 1a and 1b are closed by the string 5, but as shown in FIG. 3, a plurality of obsidian-based perlite tubes are used. Alternatively, the filling body 10 may be connected via the connecting portion 10a. The advantage of connecting a plurality of obsidian-based perlite cylinders 10 in this way is to unify the adjacent obsidian-based perlite cylinders 10 by unwinding the adjacent strings 5. Is possible. That is, since the length of the obsidian-based pearlite tubular body 10 can be doubled or tripled by an extremely simple method, it can be arbitrarily changed according to the situation of the construction site. Needless to say, the obsidian-based pearlite tubular body 10 having the initial length can be obtained by cutting the connecting portion 10a.

Further, in the above-mentioned embodiment, the obsidian pearlite 3 and the solidified fertilizer 4 are stored in the body of the tubular packing body 1. As a storage method, for example, instead of the solid fertilizer 4, Liquid fertilizer may be used to impregnate the obsidian-based perlite 3 or the solidified fertilizer 4 may be stored in the center of the tubular body 1 and the obsidian-based perlite 3 may be placed around it. If stored, the effect of suppressing the outflow of the fertilizer 4 is great, and it becomes possible to supply the required minimum fertilizer 4 for a long period of time. It should be noted that the purpose of the present invention cannot be achieved without storing the fertilizer 4 in the tubular body 1 and the storage of the fertilizer 4 is not an essential requirement of the present invention.

Further, in the above-mentioned embodiment, as long as the tubular body 1 is durable enough not to be damaged at least until it is buried, the size and method of knitting are arbitrary, and both ends are The blockage of 1a and 1b is not limited to the string 5, but may be a tape, a metal fitting, or the like made of the same material as the body 1 of the tubular body.

[0032]

[Effect of device]

 As described above, the obsidian-based perlite tube packing body according to the present invention constantly feeds air into the soil by the obsidian-based perlite stored in the obsidian-based perlite and keeps an appropriate amount of water and also removes excess water. Since it can be drained, it prevents root rot of trees and supplies water that is indispensable for growth so that it does not become dead trees. Further, although the obsidian-based pearlite is granular, it is easy to handle for transportation and construction because it is stored in the tubular packing body in a form that does not leak.

Further, as described in claim 2, by storing the fertilizer together with the obsidian pearlite in the body of the tubular packing body, the fertilizer flows out together with the water and promotes the trees. Therefore, the trees will not become dead without irrigation, and the trees will be mature without sprinkling fertilizers, thus simplifying plant management.

Further, as described in claim 3, by opening the obstruction of the obsidian-based perlite cylinder packings which are adjacent to each other, the obsidian-based perlite cylinder packing is one obsidian-based perlite. Since it can be doubled, tripled, etc. to its original capacity, it is not necessary to prepare obsidian-based perlite with several different capacity in advance. It has the advantage that it can be changed arbitrarily.

Further, as described in claim 5, by forming the body of the tubular body with a biodegradable resin, the body of the tubular body serves as a nutrient source for soil animals, microorganisms, etc. for soil improvement. It promotes soil improvement and does not become waste because it does not remain semi-permanently.
