Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repellent tool for flying wing pests, etc., which protects a plant from flying wing pests and harmful birds by installing a repellent material in the vicinity of a plant to be cultivated and grown. The present invention relates to a repellent device such as a flying wing pest that effectively controls food damage and infectious diseases of agricultural products even if it is a repellent material.

[0002]

2. Description of the Related Art Conventionally, a tape formed by cutting a polyester film on which aluminum has been vapor-deposited into strips or a tape colored in red or the like is stretched over agricultural crops or on the sides of a crop, and the reflected light from the tape spoils sparrows and the like. There are known so-called sparrow threat and pest repellent methods of driving away harmful birds.

However, since this conventional tape utilizes specularly reflected light, it is effective only in a fixed direction, so there is a limit to reducing food damage and infectious diseases of agricultural products. Therefore, in order to reflect in multiple directions, attempts have been made to use a polyhedron such as a mirror ball as shown in FIG. However, even if it is a polyhedron, the reflected light can reach only a specific angle, so it is not a fundamental solution. Further, in order to place the reflected light in multiple directions, it is necessary to make it more polyhedral, but there is a problem that it is not easy to manufacture.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The repellent material used in the present invention is
A non-woven fabric made of thermoplastic resin, and as the thermoplastic resin, polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-butene copolymer, ethylene
Examples thereof include vinyl acetate copolymer, polystyrene, vinyl chloride, polyester, polyamide and the like, and among them, high density polyethylene is preferable.

[0008] nonwoven basis weight is used as a 20 to 100 g / m ^2, had a basis weight between 20 to 100 g / m ^2, the vehicle as a repellent tool pests is less than 20 g / m ² This is because the formability is insufficient, the reflectance is lowered, and when it exceeds 100 g / m ² , the cost becomes high. The preferred basis weight is in the range of 30 to 60 g / m ² . The non-woven fabric used has a visible light reflectance of 60% or more, and the reflectance is defined as 60% or more.
This is because if it is less than%, the problem of the present invention of preventing food damage due to harmful insects cannot be solved. The reflectance can be measured, for example, by
It can be performed using Hitachi spectrophotometer U-3210 type (integrating sphere type).

In the present invention, the repellent material is preferably at least one selected from a band, a twisted or knitted body of the band, a regular tetrahedral woven body, a film sheet, or a combination thereof. . All of these forms are simple forms and are easy to manufacture.

The repellent material is a strip or a twisted or knitted body of the strip, and at least one of them is preferably installed as a support for plant cultivation. In the case of a conventional strip using a specular reflection light, it is impossible to use as a support in view of the relationship between incident light and reflected light of sunlight, but in the present invention, it is possible because diffuse reflection is used, Greatly contribute to expansion. When twisting the strip, it is also preferable to twist along the reinforcing material. As the reinforcing material, a plastic stretch tape, a flat yarn, a monofilament or the like can be used alone or in combination.

Furthermore, since the repellent material is a strip and the strip is stretched, the strip can be prevented from extending. Non-woven fabric made of a thermoplastic resin containing a filler is capable of diffuse reflection, but in the case of a band-shaped body, it may extend and cause trouble depending on the installation mode. In such a case, stretching can be prevented by stretching.

Further, in the present invention, the repellent material formed in a regular tetrahedral woven body is hung from the upper part of the plant,
Alternatively, by laying the repellent material formed in the form of a film sheet in a field for plant cultivation, it is possible to more effectively prevent the feeding damage of pests and the like from the past even by simply using the repellent material in a simplified form.

The above-mentioned thermoplastic resin non-woven fabric can be used as a repellent material in a simplified form as described above, but for that purpose, it is preferable that the non-woven fabric is given shapeability. Increase the strength of your own waist,
It is also preferable to increase the thickness or line it with another material.

The non-woven fabric used in the present invention can be produced, for example, by flash spinning high-density polyethylene or spun-bonding polyester. The thickness of the fibers of the non-woven fabric is not particularly limited, but it is better to be as thin as possible to improve the reflectance, and generally 0.1 to 1
It is about 0 μm, preferably 5 μm or less. The thickness of the non-woven fabric is not particularly limited, but about 0.1 to 1.0 mm is suitable for imparting shapeability depending on the thickness.

As the non-woven fabric used in the present invention, a tape-shaped strip may be used as it is, a plurality of strips may be twisted or knitted, a non-woven sheet may be used, or one or more sheets may be used. After cutting the non-woven sheet, it can be woven into a regular tetrahedron shape, a woven crane shape, and various other three-dimensional shapes. When using it as a woven solid,
It is preferable to fold it in a plane when it is stored and to expand it into a three-dimensional shape when it is used.
