Abstract

PURPOSE: To provide an artificial soil substitutive for natural soil in order to grow plants. CONSTITUTION: This artificial soil is constituted by using fine chips of wood or large sawdust as a main raw material 12, mixing a highly water absorbing resin capable of absorbing water and retaining the water therein, adding a mucilaginous binder such as a starch paste or agar thereto and forming the resultant mixture into a desired shape.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to artificial soil, and more particularly to an artificial substrate for growing plants.

[0002]

2. Description of the Related Art Plants grow by absorbing root nutrients contained in soil from the roots by supporting the stems and leaves in the natural earth. Water, gravel, sand, rock wool, and the like have been conventionally used as an artificial cultivated place to replace the natural soil.

[0003]

In the conventional artificial soil using rock wool or the like, there are many problems in its use because the rock wool itself is a fiber made of glass.

Further, this type of artificial soil has a disadvantage that it does not adapt to natural soil even if a plant is cultivated for a long period of time.

In view of these various problems, the main object of the present invention is to provide an artificial soil which does not use any inorganic material.

The object of the invention is also for example rock slopes,
The purpose is to provide an artificial soil that is effective for beautifying the environment by covering the slope slopes of soil free from the risk of rockfall and erosion, existing concrete slopes or revetments composed of concrete blocks with green.

Another object of the present invention is to provide an artificial soil which is optimal for germination and growth of plants and which can be adapted to natural soil.

An object of the present invention is to provide an artificial soil which is particularly constructed as a block and is extremely convenient for transportation, construction and the like.

[0009]

DESCRIPTION OF THE INVENTION In order to achieve the above-listed objects and other objects, the artificial soil 10 of the present invention has, as a main raw material, about 95% or more of the total volume thereof is fine wood chips or sawdust 12. A highly water-absorbent resin powder capable of absorbing and retaining water, for example, "Aquaric" under the trade name is mixed and formed into a desired shape with a starch paste or a viscous binder such as agar.

The molding can be carried out by filling a mold with these materials in order to obtain a block having a desired shape. As shown in FIG. 1, cotton, linen, non-woven fabric and other By interposing one or a plurality of woven cloths 14, the original mold can be maintained after being taken out from the mold.

If wood chips or sawdust as the main raw material is preheated to carbonize its surface to some extent, it is effective as an ash fertilizer when planted.

The superabsorbent resin is useful for supplying water to the roots of plants because of its property of absorbing water and storing it.
Further, a fertilizer, which is essential for the growth of seedlings, can be mixed into the above material.

Further, if a large number of small pores are formed on the surface and inside of the block-shaped artificial soil, the block itself becomes more porous, which is effective for the root growth of plants.

In order to make the block-shaped artificial soil porous, it is possible to mix finely crushed pebbles, pumice, or rough sand.

[0015]

Since the artificial soil of the present invention is constructed as described above, it can be replaced with the natural soil in the plant factory.

[0016] In addition, if a rock slope, a shoulder, a concrete slope or the like of a steep slope is covered with the artificial soil of the present invention and a plant is planted, slope protection and greening can be performed at the same time.

Furthermore, for example, if seeds of grass are spread on each block of the artificial soil of the present invention, it is very convenient that the lawn can be constructed by arranging the blocks on the ordinary ground surface. Its constituent materials do not harm the natural soil.
