Abstract

PURPOSE:To provide soil with proper water permeability and water retention by laying finely granular mineral fiber mixed layer on a lower layer and spreading a humus-containing culture bed mixed layer on the finely granular mineral fiber mixed layer. CONSTITUTION:The ground 2 is dug up in width suitable depending upon kinds of plants to form a long channel 3 and a finely granular mineral fiber mixed layer 4 such as finely granular rock fiber is laid on a lower layer. Then depth and width of a layer 6 mixed with a proper amount of a humus-containing culture bed are decided based on size of plants 5 to be cultivated and the layer mixed with a proper amount of a humus-containing culture bed is spread on the finely granular mineral fiber mixed layer.

Description

[Detailed description of the invention] [Industrial application field] This invention improves the soil in which plants are grown.

It aims to promote the growth of plants, and the concept of plants includes general field crops and flowers.

[Conventional technology]

When cultivating plants, it is common practice to provide soil with an appropriate amount of moisture so that the plants can grow without any hindrance.

[Problem to be solved by the invention J] In this case, an excess of water will cause rooting, and an insufficient amount will cause the plant to die, so it is necessary to provide the soil with appropriate water permeability and water retention. is an important issue.

[Means to solve the problem]

Here, the present invention provides a layer containing fine granular mineral fibers in the lower layer of soil for cultivating plants.

This invention proposes a soil cultivation method using a humus-containing culture bed, which is characterized by providing a layer mixed with a humus-containing culture medium in the upper layer to promote plant growth.

[Effect]

That is, in this invention, the soil in which plants are to be cultivated is dug, first a layer mixed with fine granular mineral fibers is laid in the lower layer, and then a layer mixed with a humus-containing culture medium is laid on top of it.

[Embodiment 1] Next, an embodiment of the present invention shown in the accompanying drawings will be described.

The example shown in FIG. 1 is an application of the present invention to cultivation covered with mulch film.Generally, when plants are planted in soil and covered with mulch film 1, the ground 2 is covered with mulch film 1 with a width that is appropriate depending on the type of plant. Dig in to form long groove 3.

A layer 4 containing fine granular mineral fibers such as fine granular rock fibers is provided in the lower layer. The amount of mineral fiber mixed in should be appropriate (approximately 5 to 10% based on the amount of soil). If the amount mixed in is too large, except in the case of full-cover cultivation, one copy should be added in case of abnormal weather (heavy rain, drought, etc.) May cause water or drying phenomena.

No organic matter is mixed into this layer 4 mixed with fine grained mineral fibers.

The reason for this is to prevent organic matter from rotting in the event of overwatering. In addition, fibers other than mineral fibers are
Not suitable as a material. For example, organic fibers decompose quickly;
Synthetic fibers may become foreign substances in the soil.

On the other hand, since mineral fibers are made from rocks, there is no risk of them becoming foreign substances in the soil.

Next, the depth and width are determined depending on the size of the roots of the plants 5 to be cultivated, and a layer 6 mixed with an appropriate amount of humus-containing culture medium is laid down. (About 5-10% of the amount of soil). At most, the limit of moisture management without using a meter is about 15%.

Here, an example of the humus-containing culture bed component is as follows. That is, total amount of nitrogen: 0.33 Total amount of phosphoric acid: 0.76 Total amount of potassium: 0.70 Therefore, the required fertilizer components are supplied to this layer depending on the type of plants to be cultivated.

Furthermore, when covered with a mulch film, rainwater impregnates the soil outside the film and runs off, making it difficult for plants to use it effectively. Pour into layer 4.

In this case, water is retained in mineral fibers.

Good water permeation into the layer 4 mixed with fine grained mineral fibers.

Leaves fall on the ground surface in this layer to prevent drying.

In order to avoid overwatering of the mineral fiber mixed layer 6 that forms the covering layer 7 of straw, hay, etc., the amount of #I granular mineral fiber mixed is about 10% or less of the soil volume. Also, in the mineral woven layer.

To improve the movement of water through capillary action.

Mineral fibers are made into fine particles and thoroughly mixed with water.

When renewing crops, cultivation is limited to this layer 6 of the humus-containing culture medium, and is not tilled to the level 4 of the mineral fiber mixture.

Since the humus-containing medium contains many microorganisms, it can prevent the occurrence of soil diseases.

[Example 2] The example shown in FIG. 2 is a case where the present invention is applied to tunnel cultivation, in which the plants 5 on the fine-grained mineral fiber mixed layer 4 constructed in the same manner as the example shown in FIG. Several planted humus-containing culture bed mixed layers 6, 6 are simultaneously covered with a transparent film 8, and the other structure and operation are the same as those using the multi-film coating method shown in Fig. 1. .

〔Effect of the invention〕

According to this invention, the following effects can be obtained.

Moisture from medium rainfall or watering quickly permeates underground and is retained in the humus-containing medium layer and the fine granular mineral fiber layer.

b2) Moisture necessary for plant growth is transferred and effectively utilized by the capillary action of mineral fibers.

During mid-plant regeneration, no tillage is required, or tillage up to the humus-containing medium layer is sufficient, which saves labor.

4) Can be cultivated in rough sandy soil.
