Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sowing sheet and a method for manufacturing a sowing sheet.

2. Description of the Related Art In sowing work in agricultural work, it is troublesome to sow a fixed number at regular intervals, and it is also troublesome to apply thin soil over the seeds in order to prevent bird damage, wind damage, rain damage and the like. In addition, when seeding on the ground surface, there is a problem that insects are likely to be damaged during germination and that the quality of soil to be seeded is easily varied. Furthermore, it takes a lot of time to remove germinated weeds, and the spraying work is a burden.

On the other hand, as a conventional seeding sheet, a "seeding sheet" (Japanese Patent Laid-Open No. 4-200303, Conventional Example 1) is known. The sheet is composed of a "base sheet having a light-shielding property and having a plurality of holes perforated, and a coating sheet having water-disintegrating property and biodegradability, which are bonded to each other, and the coating sheet at a position corresponding to each hole. The seeding sheet, characterized in that the seeds are fixed to the joint side surface with a water-soluble adhesive.

Further, Japanese Patent Laid-Open No. 3-191703 "seedbed sheet" (conventional example 2) is also known. The same "seed bed sheet" is a "water-soluble adhesive in which heat-storing material and fertilizer are evenly kneaded between two sheet-like materials, so that seeds of dense perennial plants such as grass and grass are evenly attached. Seedling sheet characterized by being formed. ”

[0005]

However, in the seeding sheet of Conventional Example 1, the seeds “on the joint side surface of the covering sheet at the position corresponding to each hole” of the “base sheet having a plurality of holes” are seeded. There is a problem in that the step of adhering the seed to the base material is indispensable, not the method of fixing the seed with the base material itself, since it is fixed with an adhesive.

[0006] In Conventional Example 2, since the surface coating is melted, the seed coated with the surface coating is exposed over time, and the seeds are blown off by wind or washed off by a large amount of rain as in the case of the open field lacquer plant. In addition to being directly exposed to water, there was a problem that it would not germinate unless it rained due to lack of water retention.

[0007]

Alternatively, as shown in FIG. 3, a notch groove 22 having a wide surface side and a narrow bottom portion is provided, and a slit 21 is provided below the notch groove 22, and further below the slit 21 in the notch groove 22 forming direction. You may provide the cylindrical communication hole 23 along it. The slit 21 of this embodiment may also be formed as an intermittent slit, and the slit 21 is not provided, and the communication hole 23 is formed below the cutout groove 22.
May be provided.

Alternatively, the surface of the substrate 11 may be provided with a plurality of holes 25 as shown in FIG. The hole 25 may have a closed surface as if it was actually stabbed with a needle, or may have an open surface. The shape of the hole 25 is not particularly limited. Furthermore, in the embodiment shown in FIG. 5, a semi-cylindrical groove 2 is formed on the surface of the base material 11 along the longitudinal direction of the base material 11 and has an upper surface opening.

In order to manufacture the seeding sheet shown in FIGS. 2 to 8, after forming the slit 21, the notch groove 22, the communication hole 23, the groove 24, the hole 25 and the like in the base material 11, the base material 11 is formed. The surrounding four sides or two sides are shown in FIG. 2 (B), FIG. 6 (B), and FIG.
(B), as shown in FIG. 8 (B), the gap of the tension slit 21, the groove width of the grooves 22, 24 or the hole 23, the hole 2
Increase the diameter of 5. Alternatively, instead of pulling the periphery of the base material 11, as shown in FIG. 11, the side of the base material 11 on which the slit 21, the groove 22, the groove 24, or the hole 25 is formed is the outer side, and the roller 31 and the like are sequentially arranged. By passing and bending, the gap of the slit 21, the groove width of the grooves 22 and 24 or the hole 2
3. Increase the diameter of hole 25.

In addition to expanding the gap or diameter,
Seeds the slit 21, communication hole 23, groove 24 or hole 2
Insert in 5. The seeds are inserted by sowing the seeds on the base material 11 in which the slits 21 are widened. Alternatively, the base material 11 in which the gap of the slit 21 is widened is passed through the seed drop position. Alternatively, the slit 21
The seeds are pushed into the slits 21 and inserted without widening the gap between the seeds.

Next, the pulling or bending of the base material 11 is loosened or released to hold the seeds in the slits 21 or the like to obtain a seeding sheet.

In the embodiment shown in FIGS. 9 and 10, the surface of the substrate 11 or the slits 21 and the grooves 2 are used.
4, seeds are sown in the holes 23 and 25 in the same manner as in the above embodiment. Then, a seeding sheet is obtained by covering the seed with a surface material and adhering it to a base material. Base material 11 and surface material 12
It is preferable that the adhesion with the is partially performed rather than the entire surface. The adhesive is not particularly limited.

The seeding sheet can be stored without occupying a space if the seeds do not drop from the sheet if the seeding sheet is rolled up with the formation surface of the slit 21 and the like inside. Facilities for Tabata include
It is possible to adopt a method in which the slit 21 or the like is dropped from the rear side of the tractor with the slit 21 or the like facing upward, and then the tractor is sequentially dropped. FIG. 1 shows an example of the installation state of the seeding sheet, and 41 is a holding plate having an L-shaped cross section, which is appropriately attached along both longitudinal ends of the base material 11. In general, since the buds are weaker than the roots at the time of germination, the slit forming surface or the like is raised, so that the germination occurs along the slits 21 and the like, and the germination rate is increased. When the slits 21 are formed by penetrating the front and back surfaces of the base material, since there is no directionality, sheet winding work and facility work are easy.
