Abstract

<P>PROBLEM TO BE SOLVED: To provide a soil-surface coating material solving such problems that a conventional soil-surface coating material does not prevent invasion of insects because of being bored when fixed and causing breakage or making gaps between weights when putting the weights thereon, takes much time for putting soil thereon, and requires spaces for putting on the soil thereon. <P>SOLUTION: This soil-surface coating material comprises a long coating material 10 which covers the surface of the soil, and both end parts 10a of which are fixed. The material is structured as follows: a water-tight and flexible tube 30 is attached to the both end parts 10a in its longitudinal direction; and fluid is charged in the inside of the material so as not to make the coating material float from the surface of the soil. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a covering material covering a soil surface when a crop is sown or covering a growing plant. The covering material here includes a solid cover and a tunnel solid cover, and further, as a covering material, It includes a resin net, cold water, long-fiber non-woven fabric, and further a plastic sheet (hereinafter simply referred to as a coating material).

  In the case of crops, especially leaves, there are many cases that cannot be sold due to external factors, and the leaves may be eaten by birds, green worms, and the like. For this reason, there is a method in which a semi-circular support column is erected on the seeded seedling, and this is covered with a covering material such as a polypropylene net material, a cold soot, or a film sheet to protect it as a tunnel shape. is there.

  In addition, there is a case where so-called sticking is performed to directly cover the sowing pods, and for this, for example, a covering material made of a nonwoven fabric made of polypropylene is mainly used. Furthermore, in order to prevent moisture from evaporating from the soil and suppress the generation of weeds, soot is covered with a so-called multi-sheet film sheet covering material.

  These covering materials are arranged so as to match the longitudinal direction of the ridges, and fix both width edges, and when both width edges are not fixed or insufficiently fixed, they are beaten by wind or the like, There are cases where the covering material is peeled off or repeatedly brought into contact with the crop and cannot be sold. For this reason, as a fixing means for both width edges, means for filling the width edges in the soil or inserting them into the soil with a special fixing tool has been used.

  As fixing means, (a) a method in which a U-shaped piercing member penetrates the edge of the covering material and pierces the soil, (b) a method in which a weight member is placed on the edge of the covering material, and (c) a covering. There is a method of placing soil on the edge of the material.

  Disadvantages of the above method are that the method (a) has a phenomenon that a hole is opened and broken in the method, and the method (b) takes time to put weights, and a gap is opened between the weights, so that insects can enter. The method (c) takes time to put the soil and requires a space for placing the soil, and has been required to be improved.

  The present invention is a technique for fixing both width edges of such a covering material, and provides a simple and reliable fixing means.

  The gist of the present invention is a long covering material that covers the soil surface and fixes both edges, and is equipped with water-tight and flexible tubes in the longitudinal direction at both ends, and fluid ( Water) is poured to prevent the covering material from floating above the soil surface.

  The present invention has the above-described configuration, and is equivalent to the fact that a weight is formed over the entire area of the longitudinal edge of the coating material by filling the tube with water. The material can be adhered to the soil surface. The covering material is easy to handle, and it is easy to be weighted by filling the tube with water, and it can be easily folded by draining water, making it reusable. .

  As described above, the covering material according to the present invention is applied to the covering material that covers the soil surface when the crop is sown as described above, and the covering material referred to here is a solid covering material on the soil surface, a tunnel covering member, or the like. In addition, as the covering material, a resin net, a cold chill, a long fiber nonwoven fabric, and further a plastic sheet are included.

  Here, if the covering material is described with a resin net material that is applied directly or in tunnel form to the sowing seeds, specifically, a tricot knitted fabric made of synthetic fibers such as nylon and polypropylene, preferably a tricot half It is a knitted resin net material. Such a tricot knitting is knitted with a structure having little elongation in the longitudinal direction and extremely well extending in the width direction. Moreover, because it is a tricot half knitting, it has a very light and soft feel, and even if the buds of the sowed plant touch it, it will not be damaged, and even if the leaves grow, the resin net will extend in the width direction The feature is that there is no need to repeat the operation.

  The tube is not particularly limited as long as it is made of a flexible and watertight material, but a thin resin tube such as polyethylene, polypropylene, or vinyl is preferable. Of course, other materials may be used.

  There is no particular limitation on the tube mounting / integrating to the edge of the covering material, but the entire tube may be provided at the edge, for example, the tube edge is formed in a cylindrical shape. A method of inserting the tube into the tube, a method of integrating the tube edge with an adhesive, a method of integrating the tube edge with an adhesive, and a covering material and the tube. If it is a material of the same effect, the method of heat-sealing etc. can be illustrated.

Hereinafter, the present invention will be described in more detail with reference to examples.
FIG. 1 is an overall view of a first embodiment of the present invention, FIG. 2 is a view showing only a covering material, and FIG. 3 is a view showing only a tube.

  The covering material of the present invention, that is, the solid resin net 10 is a nylon tricot half knitted resin net. The thickness of the nylon fiber constituting the resin net is 17 to 78 dtex (T), and in this example, 17T is used. The stitch size was 23 ± 2 courses × 28G.

  The covering material 10 is not very stretchable in the longitudinal (warp) direction L, and substantially maintains its length, but has a large stretchability in the width direction and brings about a large elongation. Therefore, as shown in FIG. 1, the longitudinal direction of the cocoon and the longitudinal direction of the covering material 10, that is, the warp direction, are matched with the cocoon 20 sown with the seeds of the crop, and the covering material is applied in the width direction of the cocoon 20. The tunnel is solid so that the direction in which the elongation of 10 is brought about coincides.

  In the covering material 10, the edge 10a is bent and sewn 11 to form an annular portion 10b. A tube 30 made of vinyl is inserted into the annular portion 10b, and water is filled from a base 31 provided at the tip of the tube 30.

  Accordingly, a weight is formed by the water filled in the tube 30, so that the covering material 10 surrounds the flange 20, and both edges 10 a and 10 a are held down, so that the covering material 10 is surely placed on the flange 20. Will cover.

  FIG. 4 is a view showing a second embodiment of the present invention, in which a double-sided tape is used for the edge 10a of the covering material 10 and the tube 30 is mounted by the adhesive material 12. FIG.

  The present invention is as described above, and the covering material can be surely covered with the soil surface, and there is no fluttering even in strong winds, and the growth of the crop is sufficient.
