DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant growing floor formed by using a cultivating soil prepared by dividing a soil from a base soil or an agricultural land via a root-proof water-permeable sheet. The present invention relates to a plant rhizosphere-suppressed cultivation method characterized in that a plant is cultivated with only roots.

[0002]

2. Description of the Related Art Hitherto, it is said that the most important factors in cultivating plants such as agricultural crops are balanced fertilization, good water for crops, and an appropriate environment. It is said that the best improvement among them is good soil creation by "balanced fertilization". For this reason, many people have been determined to create soil suitable for the plants they grow. However, the nature of soil differs from place to place, and it is difficult to artificially change the original soil properties. It is impossible to replace all the soil on farmland, even if you try to partially improve the soil. Even if the soil is superficially improved, it is only temporary, and its maintenance and management requires enormous costs. That is, in the case of agricultural land containing a large amount of salt, even if the soil in the surface layer is improved, the salt rises from deeper soil and eventually salt damage cannot be prevented. In addition, when the agricultural land is contaminated with pathogenic bacteria, the pathogenic bacteria often come up on the surface soil and contaminate the plants, and the plants are often infested with the bacteria. It is very difficult to prevent such a phenomenon.

[0003]

SUMMARY OF THE INVENTION The inventor of the present invention has been affected by the inherent characteristics of the land even if the soil on the farmland or the base soil is temporarily and superficially improved. We have been studying how to solve the following technical issues at the same time.

[0004] Isolation of cultivation soil from agricultural or base soil. The plant growth floor made of cultivation soil must be at least as large and as large as necessary for the plants to take root, and the soil can be controlled. The excess water from the upper cultivation soil seeps into the lower cultivated soil and the base soil and migrates, but nutrient components and pathogens from the lower cultivated soil and the base soil rise to the higher cultivation soil. Don't come over. Cultivating plants using only the plant growth floor that can be controlled as described above in the rhizosphere.

[0005] As a result of the research, the soil of the farmland or the base soil and the cultivation soil are separated via the root-proof water-permeable sheet, and the concentration of the nutrient solution component in the cultivation soil is lower than the concentration of the nutrient solution component soil in the farmland. It has been found that the above technical problems can be solved at the same time by adjusting.

Based on such new technical knowledge, the present inventor has formed a plant growing floor using a cultivated soil prepared by dividing a base soil or an agricultural land through a root-proof water-permeable sheet. A new plant rhizosphere characterized by adjusting the concentration of nutrient solution components in the cultivation soil, and then cultivating the plant while controlling the nutrients to be absorbed by planting roots only on the plant growth floor. A suppression cultivation method was developed.

[0007]

According to a first aspect of the present invention, a root-proof water-permeable sheet is laid on a base soil, and a cultivation soil is placed thereon. Is separated through a root-proof water-permeable sheet, and the classified cultivation soil is sterilized or fertilized as necessary,
In addition to making soil suitable for the plant to be cultivated by adjusting the pH, etc., the concentration of the nutrient solution in the soil for cultivation is adjusted to be lower than the concentration of the nutrient solution in the base soil, and then the adjusted cultivation This is a plant rhizosphere-suppressing cultivation method characterized by forming a plant growth floor using soil, and cultivating a plant by setting roots only on the plant growth floor.

[0008] The first invention is a basic invention of a method for suppressing rhizosphere cultivation of plants. Here, the base soil may be any soil that can hold soil for cultivation and serve as a base, and is a base soil created by putting the soil in an artificially restricted container or a nursery box. Or a base soil created by cultivating land such as farmland.

[0009] The root-proof water-permeable sheet is a water-permeable sheet, such as cloth, non-woven fabric, synthetic resin membrane, woven fabric, etc., which does not allow plant roots to pass through the sheet.
The material is not particularly limited.

[0010] Furthermore, the cultivation soil at the top of the sheet is:
The soil is made and the concentration of the nutrient solution is adjusted to be lower than the concentration of the nutrient solution in the lower base soil or the soil of the agricultural land. As a result, excess water and nutrient solution that permeates from the upper layer pass through the root-proof water-permeable sheet and escape to the lower base soil, but the soil nutrient components of the base soil become osmotic and capillary. It is possible to prevent an increase due to a phenomenon or the like, and further prevent a pathogenic bacterium in the base soil from rising to a higher cultivation soil and damaging the plant. in this way,
By adjusting the concentration of the nutrient solution component in the cultivation soil, the plant growth environment of the cultivation soil in the rhizosphere can be favorably maintained.

[0011] The present invention, as described above, is to make roots only on plant growing floors made of soil for cultivation, which is made of cultivated soil managed in a favorable environment. The plant is cultivated with the rhizosphere suppressed so as not to go. As a result, the cultivated plant can control the nutrient solution components absorbed from its roots,
A good growth state can be maintained and a good harvest can be obtained.

[0012] The second invention for which a patent is sought is to form a hole-shaped or groove-shaped concave portion in the soil of agricultural land, lay a root-proof water-permeable sheet on the concave portion, and cultivate the cultivation soil in the concave portion. Backfill the recesses to separate the farmland soil and the cultivation soil through the root-proof water-permeable sheet, sterilize the cultivated soil as necessary, or perform fertilization treatment Or adjust the pH to adjust the pH of the nutrient component of the cultivation soil to be lower than the concentration of the nutrient component soil of the base soil. A plant growth floor is formed using the grown cultivation soil, and a root is formed only on the plant growth floor so that the plant is cultivated.

In order to carry out the present invention, when the soil of the agricultural land and the soil for cultivation are separated via the root-proof water-permeable sheet, a hole-shaped or groove-shaped concave portion is formed in the soil of the agricultural land, This is a method in which a root-proof water-permeable sheet is laid on the concave portion, and cultivation soil is placed on the concave portion above the concave portion to refill the concave portion. In this method, farmland is used as it is as the base soil, and it is only necessary to cultivate the farmland, and the work is easy and simple. It is economical because it has only seats. Moreover, controlling only the soil for cultivation on the limited plant growth floor does not affect the soil characteristics of the farmland, so the cultivation of agricultural crops is simplified and many pests and insects can be prevented. Is overwhelming. Therefore, this method is highly practical as a new cultivation method.

[0014] A third invention, which is to be patented, is characterized in that the soil preparation and adjustment of the cultivation soil described in the first invention and the second invention are performed by liquid fertilizer, wherein the rhizosphere-suppressed cultivation of plants is performed. Is the law.

[0015] If the plant growing floor is formed using the adjusted cultivation soil, and the soil is prepared and adjusted by liquid fertilizer, the adjustment can be performed efficiently and easily.
Plants can be cultivated in an environment close to ideal.

[0016]
