Abstract

PURPOSE:To improve the operating efficiency in weed control by using a control unit in place of a conventional black plastic film. CONSTITUTION:This method for controlling weeds is to cover a crop, a tree, etc., with a control unit 1 composed of a jute bag in the growing period of the crop or tree and convert the control unit into a fertilizer by the decomposition of the control unit as the crop or tree grows.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling weeds and a control body for controlling weeds.

[0002]

2. Description of the Related Art Conventionally, a method of laying a black plastic film has been used as a method for controlling weeds that occur in fields such as strawberries, gardens, trees and the like.

[0003]

However, although the black plastic film is excellent in controlling weeds and shading, it must be removed one by one when it becomes unnecessary as the crops, trees, etc. grow. , This work was very troublesome. In particular, nurseries and young trees are replanted after growth, but the work at this time can be said to be extremely complicated.

An object of the present invention is to provide a method and a control body for weeds, which is excellent in workability for controlling weeds.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention covers a control body made of natural fibers during the growing season of crops, trees, etc., and corrodes the control body as the crops, trees, etc. grow. The method of controlling weeds by fertilizing the control body by the method, and at the time of growth of crops, trees, etc., the control body made of a self-disintegrating synthetic resin is coated on the crops, trees, etc., along with the growth of the crops, trees, etc. A weed control method was adopted in which the control body disappeared by self-disintegration of the control body.

Any controllable body of natural fiber may be used as long as it covers crops, trees, etc., exhibits a light-shielding property, and decays and corrodes with the growth of crops, trees, etc. to form fertilizers. The fertilized pest control body may have a direct fertilizing effect on the growth of crops, trees, or the like, or may be replanted or mowed with the crops, trees, etc., and then plowed to fertilize the part. Therefore, various control bodies such as woven and knitted fabrics such as hemp and cotton can be used.

As the control body made of synthetic resin, a plastic sheet or fiber that self-disintegrates by microorganisms, light, a decomposing agent, etc., such as self-disintegrating polyethylene, polyurethane, polyester or the like can be used. A chemical such as fertilizer can also be contained in the control body. In addition, it is also possible to use a control body in which synthetic fibers having self-disintegrating property are woven with natural fibers.

The pest control body can take various forms such as a net such as a pest control net in addition to the bag shape, and is not particularly limited.

When the control body is impregnated with a herbicide, fertilizer, insecticide or other chemicals, or a chemical solution by utilizing a natural fiber structure such as woven or knitted, the herbicidal effect is further improved while controlling. It is extremely preferable because the soil can be further fertilized as well. In this respect, hemp bags are particularly preferable because they have excellent shielding and light-shielding effects, are easily corroded with the growth of crops, trees and the like and are easily fertilized, and can be impregnated with herbicides and fertilizers. After use, it can be regenerated by impregnating it with a chemical solution again. For example, in the case of forming a weed control body with a control net, a chemical can be incorporated into the net, or a rope as a component can be impregnated with a chemical solution and knitted to form a control net.

[0010]

The present invention is to cover the crops, trees, etc. with a control body composed of natural fibers during the growing season of the crops, trees, etc., and to grow the crops, trees, etc., and to corrode the control bodies so that the control bodies are fertilized. Since it is a method of controlling weeds, it protects weeds like conventional black plastic films.
In addition to exerting a control action by shading, the control body can be made into a fertilizer by corroding the control body with the growth of crops, trees, etc., so unlike the conventional black plastic film, it is not necessary to remove it one by one, and workability is improved. Significantly improved, and exert fertilizer effect that has never been seen before.

Further, when a control body such as a control net or a hemp bag is impregnated with a chemical such as a herbicide or a fertilizer, the chemical gradually flows out from the control body, so that the amount of pesticide used is remarkably reduced. At the same time, there is a particularly remarkable effect that can be applied permanently.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing an embodiment of the weed control body according to the present invention, and FIG. 2 is a schematic enlarged view thereof.

In the figure, reference numeral 1 denotes a pest control body comprising a hemp bag made of natural fibers for covering crops, trees and the like.
As shown in FIG. 2, the herbicide 3 and the fertilizer 4 are impregnated in the fiber yarn 2 that constitutes the bag-shaped net structure.

Therefore, if the control body 1 is coated on the crops, trees, etc. during the growing season of the crops, trees, etc., in addition to the conventional black plastic film, the weeds are shielded and shielded from light, and in addition to the above, the control effect is exerted. Furthermore, since the control body can be used as a fertilizer due to the corrosion and decay of the control body with the growth of crops, trees, etc., unlike the conventional black plastic film, it is not necessary to remove it one by one, and workability is greatly improved. Furthermore, since the chemicals gradually flow out from the control body, the amount of agricultural chemicals used can be significantly reduced and the fertilizer can be applied permanently.

The herbicides, fertilizers and insecticides contained in the control body are not particularly limited. However, since the control body is composed of natural fibers which easily corrode and decompose, it is not preferable to promote the corrosion of the natural fibers at an early stage. . However, depending on the natural fiber, if the corrosion period is delayed due to the relationship with the cultivation target,
On the contrary, it is preferable to include a herbicide or a fertilizer which easily corrode. Various kinds of herbicides, fertilizers and insecticides such as solutions, powders and granules can be adopted. The control body can also be colored. That is, when a aesthetic appearance that particularly matches the surrounding environment is required, such as at a golf course, it is optimal to add, for example, a green pigment or dye to the natural fiber or synthetic resin.

The present invention is not limited to the above embodiment.

[0017]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, a control body composed of natural fibers is coated on a crop, a tree or the like at the time of growing the crop or tree, and the control body is corroded as the crop or the tree grows. Since it is a weed control method that uses the control body as a fertilizer, it does not need to be removed one by one like the conventional black plastic film when it becomes unnecessary as the crops, trees, etc. grow, and the workability is greatly improved. be able to.

Moreover, since this control body is transformed into a fertilizer by corrosion, it has a remarkable effect of fertilizing the soil. Also, by impregnating herbicide and fertilizer,
The herbicidal effect and fertilizing effect can be further exerted, and the effect of controlling the rate of corrosion by the herbicide and fertilizer is also exerted.

When a control body such as a control net or a hemp bag is impregnated with a chemical such as a herbicide or fertilizer, the chemical gradually flows out from the control body, so that the amount of pesticide used is significantly reduced. At the same time, there is a particularly remarkable effect that can be applied permanently.
