BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation plate used for revegetation such as cut slopes.

[0002]

2. Description of the Related Art As a conventional vegetation plate, for example, there is one shown in Japanese Utility Model Publication No. 4-5564. That is, sandwiching seeds and fertilizer between two water-decomposable sheets, providing a covering material in the form of straw on top of that, and heat-bonding them with a thermoplastic resin or bonding them with glue. Made of

[0003]

However, in the conventional vegetation board, an adhesive such as a thermoplastic resin or a glue is used,
Since the water-decomposable sheet and the covering material are bonded together, there is a problem in that the adhesion is costly.

Further, in the conventional vegetation plate, since it is moved by strong wind and rain just by placing it on the slope, it has to be fixed on the slope with a skewer, and there is a problem that it takes time to lay it. .

The present invention has been made in view of such conventional problems, and an object thereof is to provide a vegetation plate which can reduce the cost for bonding and can be easily laid.

[0006]

In order to achieve the above object, in the vegetation board according to the present invention according to claim 1, a clay board made by mixing straw with clay is sandwiched between two saws, and It is characterized in that seeds are sandwiched between one side and the clay plate, and each side and the clay plate are pressure bonded.

[0007] The straw is made by weaving straw roughly with a string or wire. To prevent the clay plate and the clay plate from coming apart when heavy rain falls, you may sew two thighs sandwiching the clay plate. In addition to seeds, fertilizers may be sandwiched between one side of this piece and the clay plate. The straw of the clay plate may be straw in any state, for example, compost.

In the vegetation board according to the second aspect of the present invention, two clay boards made by mixing clay with straw are alternately sandwiched between three saws, and one of the outer saws and the other one. It is characterized in that seeds are sandwiched between adjacent clay plates and each of the clay plates is crimped.

In order to prevent the vegetation plate from breaking easily, in the vegetation plate according to claim 1, it is preferable that the two saws differ from each other in the extending direction of the straws by 90 degrees. It is preferable that the straws alternately have different extending directions of the straws by 90 degrees.

[0010]

In the vegetation board according to the present invention, the clay plate sandwiched between the objects adheres each of the wood by its adhesive force,
Hold the seeds. When laying the vegetation plate, lay it so that the seeds are above the clay plate. When the vegetation board is laid, it sticks to the slope due to the weight of the clay board. The clay plate and the thigh become soft when it absorbs water, and become heavier and stick along the slope. The straw mixed with the clay makes it hard to break and becomes fertilizer after laying. The seed grows and greens the slope.

In particular, the vegetation plate according to the present invention of claim 1 is composed of one clay plate sandwiched between two saws, and has a simple structure and is easy to manufacture.

In the vegetation plate according to the second aspect of the present invention, two clay plates are alternately sandwiched between three saws, and the weight can be increased without thickening the clay plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First and second embodiments of the present invention will now be described with reference to the drawings.
Examples will be described. FIG. 1 shows a first embodiment of the present invention. As shown in FIG. 1, the vegetation board 10 has one clay board 11 and two saws 12 and 13. Clay board 11 is clay 21 and rice straw 2 of about 200g
It is made by mixing and kneading 2 and rolling it into a flat square plate. The clay plate 11 has a plane size of about 50 cm × 50 cm and a thickness of about 5 mm.

Each of the thighs 12 and 13 is formed by laying rice straws having the same length of about 50 cm in the same direction and woven roughly with a string. The size of this piece is almost the same as that of the clay plate 11. The clay plate 11 is sandwiched between two pieces 12 and 13. The tips 12 and 13 are arranged so that the extending directions of the straws are different from each other by 90 degrees.

A large number of seeds 14 are equally distributed and sandwiched between the clay plate 11 and the body 12. Seed 14
Is a turf seed. The fertilizer 15 of the seed 14 is also distributed and sandwiched between the clay plate 11 and the core 31.

The vegetation board 10 is composed of the thighs 12, 13 and the clay board 1.
1 and 1 by pressure, the clay plate 11 by the adhesive force
It is made by sticking 3. Further, the four corners of the vegetation board 10 are sewn roughly with the strings 12 and 13 on both sides with the clay board 11 sandwiched therebetween. The entire vegetation board 10 is 3.5.
It has a weight of ~ 4 kg.

Next, the operation will be described. In the vegetation plate 10 shown in FIG. 1, a clay plate 11 sandwiched between the cores 12 and 13 adheres the cores 12 and 13 by its adhesive force, and
It holds the seed 14 and the fertilizer 15. For this reason, unlike the conventional vegetation plate which is formed by sticking a water-decomposable sheet and a covering material, an adhesive material is not necessary for sticking them together, and the cost required for bonding is not required. The vegetation plate 10 is composed of one clay plate 11 sandwiched between two saws 12 and 13, and has a simple structure and is easy to manufacture.

When the vegetation board 10 is laid on the slope, the seeds 14 are laid on the clay board 11. Since the seeds 14 are covered with the thighs 12, there is no fear of being scattered by wind, rain, or the like.

The vegetation board 10 is a clay board 11 when laid.
Stick to the slope due to the weight of. Therefore, the vegetation plate 10 is
Unlike conventional vegetation boards, it can be laid simply by placing it on the slope without fixing it with a skewer, and laying is easy. When water is sprinkled on the laid vegetation board 10, the clay board 11 and the body 12,
13 absorbs water, becomes softer, becomes heavier, and sticks along the slope. Due to its weight, the vegetation plate 10 does not move after installation, due to strong wind or rain.

The straw 22 mixed with the clay 21 is the clay 2
No. 1 is hard to crack and becomes fertilizer after laying. This is also 12,1
No. 3 has a moisturizing property, prevents freezing of water, and maintains an environment suitable for growing seeds 14. The seed 14 germinates, penetrates the clay plate 11 and the body 13, and extends the root into the soil. The grown seed 14 becomes lawn and the slope is greened.

Since the material of the vegetation plate 10 is natural such as straw or clay, it does not harm the natural environment. This is also 12,13
Gradually decomposes into turf nutrients. Since the clay plate 11 performs base exchange, it absorbs and holds nutrients and maintains an environment suitable for growing grass. The vegetation plate 10 prevents spillage of soil on the slope as well as greening. The vegetation plate 10 can be used for revegetation works such as cut slopes and rocky areas.

Next, a second embodiment of the present invention will be described. FIG. 2 shows a second embodiment. As shown in FIG. 2, the vegetation plate 30 has two clay plates 31, 32 and three saw plates 33, 34, 35. Clay plate 31,3
2 and also 33 to 35 are the same as the clay plate of the first embodiment. The clay plates 31 and 32 are alternately sandwiched between the three saws 33 to 35. The three saws 33 to 35 are alternately arranged so that the straws extend in different directions by 90 degrees. As in the first embodiment, a large number of seeds 36 and fertilizers 37 are sandwiched between the clay plate 31 and the core 33 on average.

The vegetation plate 30 is composed of wood 33-35 and clay plate 3.
1 and 32 are pressure-bonded to each other, and the cores 33 to 35 are attached by the adhesive force of the clay plates 31 and 32. At the four corners of the vegetation plate 30, the thighs 33, 35 on both sides are sewn roughly with a string with the clay plates 31, 32 and the thigh 34 sandwiched therebetween. The entire vegetation plate 30 has a weight of 7 to 7.5 kg.

In the vegetation board 30 of this embodiment, two clay boards 31 and 32 are alternately sandwiched between three saws 33 to 35 to increase the weight without thickening the clay boards 31 and 32. be able to. In the vegetation plate of the first embodiment, if the thickness of the clay plate is increased in order to make it heavy, the seeds are unlikely to form roots, which may hinder its growth. On the other hand, in the vegetation plate 30 of this embodiment, since the thigh 34 is sandwiched between the clay plates 31 and 32, the growth of seeds is not hindered. The vegetation plate 30 having an increased weight is suitable for laying in such a place without fear of being blown away or flowing away even in a place where a strong wind or rain has a great influence.

The vegetation board may be constructed in three or more layers by using three or more clay boards and four or more wood boards. Further, the planar shape of the vegetation plate is not limited to a square, and may be any shape such as a rectangle or a strip.

The seeds are not limited to grass and may be seeds of other plants. In addition, the seeds may be evenly distributed on the clay plate, or may be arranged in strips or spots.
It may be unevenly distributed.

Further, the fertilizer may be arranged below the clay plate in order to prevent the seeds from causing density disorder. Further, the vegetation board may have soil microorganisms between the clay board and the body, or in the clay board or the body so that the straw constituting the clay board or the body is easily hummed.
