Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a sowing sheet.

[0002]

2. Description of the Related Art Conventionally, when sowing seeds of turf on a slope such as an embankment or a golf course, a method of sowing seeds evenly directly on the ground using a dedicated machine and covering the seeds with sand has been adopted. ,
If a large amount of rain (more than 4-5 mm per hour) falls, the seeds will be washed away. Therefore, the seeds are sown again or in a larger amount than is suitable for breeding. or,
The shed seeds grow in lowlands and drains, making them ugly.

Therefore, as shown in FIG. 4A, a lawn seed 53 is sandwiched and fixed by a thin paper 52 coated with an adhesive 51 on the entire surface, or a thin paper 52 as shown in FIG. 4B. There is one in which a grass seed 53 is sandwiched between and crimped at a predetermined portion (a dotted line portion in the drawing).

[0004]

However, in the case where the paper 52 is pressure-bonded, there is a problem that the seeds 53 are unevenly distributed in the paper 52 and the growth of the grass becomes sparse.

Further, in the case where the turf seed 53 is fixed with the adhesive 51, the germination rate of the seed 53 is lowered by the heat when the adhesive 51 is dried, and the seed 53 is struck by the moisture contained in the adhesive 51. However, there is a problem that the germination rate decreases due to rotting. Further, there is a problem that the seeds 53 sprout during storage due to the moisture contained in the adhesive 51.

The present invention has been made in view of the above problems, and an object thereof is to provide a sowing sheet capable of preventing the movement of seeds and preventing the germination rate from decreasing.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 partially coats an adhesive on the surface of a thin sheet-like substrate using natural or chemical fibers. Then, the gist is that seeds are attached to the adhesive.

Further, the seeds are grass seeds, and it is preferable that plural kinds of seeds are mixed. Further, it is preferable that the base material be wound into a roll with a predetermined width.

[0009]

According to the present invention, the seed is fixed by the adhesive applied to the surface of the thin sheet-shaped base material, so that the seed can be prevented from being washed away by rainwater. Further, since the seeds are attached to the adhesive, unlike the case where the adhesive is used, it is possible to prevent the germination rate from decreasing due to heat or moisture. Furthermore, since the adhesive is partially applied to the substrate using natural or chemical fibers, the fibers of the substrate are easily disentangled in the ground, and since the fibers rot, they do not remain unlike plastic films. .

According to the second aspect of the present invention, since plural kinds of grass seeds are mixed, the grass can be kept beautiful for a long time. Further, according to the invention of claim 3, since the base material is wound up in a roll shape, the sowing sheet can be easily stored and transported, and the seed sheet can be arbitrarily sized in accordance with the desired seed area. It can be cut and used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIG. 1, a relatively thin sheet-shaped material is used for the base material 2 of the seeding sheet 1. The base material 2 is a paper using a natural fiber, and in the present embodiment, the weight thereof is 50 grams per square meter or less,
Preferably 20 grams per square meter of paper is used and its width is set to 1 m. When the base material 2 is buried in the ground, it decomposes in about one year and does not remain in a shape.

An adhesive 3 is applied to the surface of the base material 2. The adhesive 3 is a rubber-based hot melt type,
It is applied in a plurality of linear shapes at predetermined intervals along the longitudinal direction of the base material 2. The pressure-sensitive adhesive 3 is applied onto the base material 2 by applying heat, and the surface of the pressure-sensitive adhesive 3 remains tacky even after being sufficiently cooled. The turf seed 4 attached to the adhesive 3
Are almost uniformly dispersed and held on the base material 2.

The turf seed 4 is a mixture of a plurality of types of seeds (three types in this embodiment) at a predetermined ratio and is held on the base material 2 so as to have a uniform density. In this embodiment, 7 to 13 grams of seeds 4 per square meter of the base material 2 are held.

The base material 2 is wound in a roll shape so that the release sheet 5 and the release sheet 5 are alternately arranged with the release sheet 5 placed on the pressure sensitive adhesive 3 side. The release sheet 5 is formed to have substantially the same width as the base material 2, covers the pressure sensitive adhesive 3, and the pressure sensitive adhesive 3 is provided on the back surface of the base material 2.
To prevent adhesion. The base material 2 to which the seeds 4 are adhered and wound in a roll shape is put in a bag made of vinyl or the like for moisture prevention and stored. Further, as shown in FIG. 2, the sowing sheet 1 is used so that the seeds 4 are on the ground 6.

Next, the use of the sowing sheet thus constructed will be described. As shown in FIG. 2, the release sheet 5 is peeled off and cut to an appropriate length on the ground 6 which has been leveled to some extent after being dug back, and the seeding sheet 1 is laid so that the seeds 4 face up. At this time, since the base material 2 of the seeding sheet 1 is thin, the base material 2 is arranged along the undulations of the ground 6. Next, water is applied in an amount such that the seeding sheet 1 is not broken. When sprinkled with water, the seeding sheet 1 comes into close contact with the ground 6. Then, sand 7 is put on the seeding sheet 1 to press the seeding sheet 1.

Since the base material 2 is thin when the seeds 4 germinate,
The root can penetrate the base material 2 and extend into the ground. The seed 4 in which a plurality of types are mixed has a different withering time depending on the type, so that the lawn can be kept beautiful for a long period (one year).

Since natural or chemical fibers are used for the base material 2 and the adhesive 3 is partially applied, the fibers are easily separated from each other, and since they are putrefaction, they do not remain behind and do not interfere.

As described above, in the seed sheet of this embodiment, the seed 4 is fixed to the sheet by the adhesive 3, so that the seed 4 can be prevented from being washed away by rainwater.

Further, since it is not necessary to heat the adhesive 3 by heat, it is possible to prevent the grass seeds 4 from being damaged by heat. Also, since the adhesive 3 is used,
It is possible to suppress the germination and spoilage of the seed 4 due to moisture as compared with the adhesive.

Further, since the seed 4 is a mixture of a plurality of types of seeds, the timing of withering differs depending on the type,
You can keep the lawn beautiful for a long time. Also,
Since the seed sheet 1 is rolled up, it can be easily stored and transported. Also, by cutting it to a desired length when it is used, it is possible to obtain products having various areas.

Furthermore, since the thin paper base material 2 is used,
The seeding sheet 1 can be reliably arranged along the undulations of the ground. Since the base material 2 is thin, the roots of the germinated seeds 4 can easily break through the base material 2 and extend into the ground.

The present invention is not limited to the above-mentioned embodiments, but may be made as follows without departing from the spirit of the present invention. (1) Although natural fiber paper is used for the base material 2 in the above-described embodiment, natural fiber non-woven fabric or the like may be used, or paper or non-woven fabric using chemical fiber as a material may be used. At this time, it is preferable that the fibers used in the ground within one year are loosened and decomposed and do not remain in a shape, so that the roots of the seeds 4 to be sown may break through the base material 2 and extend into the ground. It needs to be possible.

(2) In the above embodiment, the adhesive 3 was applied in a linear shape, but the adhesive 3 may be dotted as shown in FIG.
The coating may be partially applied in various shapes such as the lattice shape shown in (b) or the wave shape. At this time, the amount of the adhesive 3 and the application interval may be appropriately changed according to the amount of the seed 4.

(3) In the above embodiment, three kinds of turf seeds 4
However, two or less or four or more types of turf seeds 4 may be mixed and adhered to the adhesive 3. At this time, the mixing ratio may be appropriately changed. Further, it may be applied to sow other seeds such as rice in addition to grass.

(4) Although the rubber-based adhesive 3 is used in the above embodiment, an acrylic or other adhesive 3 may be used. (5) In the above example, the seed sheet was wound into a roll, but the release sheet 5 was cut into appropriate lengths.
You may make it stack with it. The release sheet 5 is not always essential.

[0026]

As described in detail above, according to the sowing sheet of the present invention, the seeds are fixed by the adhesive applied to the surface of the thin sheet-like base material, so that the seeds are not washed away by rainwater. It has an excellent effect that it can be prevented. Further, since the seeds are attached to the pressure-sensitive adhesive, unlike the case where the adhesive is used, it is possible to prevent a decrease in germination rate due to heat or moisture, which is an excellent effect. Furthermore, since the adhesive is partially applied to the substrate using natural or chemical fibers, the fibers of the substrate are easily disentangled in the ground, and since the fibers rot, they do not remain unlike plastic films. .

Further, according to the seeding sheet of the second aspect, since a plurality of kinds of seeds are mixed, in addition to the above-mentioned effect, an excellent effect that the grass can be kept beautiful for a long time is exhibited.

Further, according to the seeding sheet of the third aspect, since the base material is wound up in a roll shape, in addition to the above-mentioned effects, the seeding sheet is easy to store and transport, and it is desired to sow seeds. It has an excellent effect that it can be cut into an arbitrary size and used according to the area.
