Detailed Description of the Invention

The present invention relates to a material for vegetation for promoting greening of riverbeds, parks or slopes.

[0002]

2. Description of the Related Art Generally, on soil slopes such as riverbeds, parks, hillsides formed by road construction and land development, vegetation is planted and planted in order to preserve the landscape and preserve the landscape. Is being done. Then, when performing such greening, for example, a stretched grass may be used. In this stretched grass body, fibers are joined with a water-soluble adhesive as a binder to form a material for vegetation, seeds and the like are adhered and held on it, and a net or the like is further attached.

When the turf grass thus constructed is installed on a slope of soil such as a hillside, seeds adhered and held to the vegetation material start to grow, and the vegetation material is a water-soluble binder. Since it is formed by joining with
It is easily dissolved and decomposed by rainwater or sprinkling water, and does not prevent seed germination or germination.

[0004]

However, there is a problem that seeds easily run off due to rainwater or water spray. Further, if the vegetation material is formed by using a water-insoluble adhesive, there is a problem that the germination and growth of seeds attached to the vegetation material is hindered. It will limit the use of the material,
Not good. Further, conventionally, in order to solve this problem, by superposing a net body on the vegetation material, seed runoff was prevented, but in this case, the net body and its adhesion means are newly added. Required,
There is a problem that the production cost becomes high.

The present invention has been made in consideration of the above problems, and the purpose thereof is to maintain the solubility of the vegetation material due to moisture, to ensure that the seeds are allowed to germinate and germinate, and at the same time to germinate. It is intended to provide a sheet-shaped vegetation substrate and a column-shaped vegetation substrate provided with a vegetation material that allows seeds to grow without being washed away by rainwater or water sprinkling, and can surely reveal soil quality slopes.

[0006]

In order to achieve the above object, the sheet-shaped vegetation substrate of the invention according to claim 1 of the present application comprises:
A vegetation material that is made by chemically bonding heat-sealable chemical fibers as a main component, a water-soluble adhesive as a binder, and further heat-sealed in a mesh shape, and a water-soluble adhesive on the surface of this vegetation material. It is provided with the retained seeds and water-soluble paper laminated to cover the seeds. Further, the cylindrical vegetation substrate of the invention according to claim 2 of the present application is a tube formed by preliminarily heat-sealing in a mesh shape, using a heat-fusible chemical fiber as a main component, a water-soluble adhesive as a binder. It is configured by filling at least seeds and fertilizer into the vegetation material in the shape of a tree.

[0007]

In the above structure, since the vegetation material is bonded by using the water-soluble adhesive as a binder with the fibers of the vegetation material, the fibers are dissolved by the dissolution of the water-soluble adhesive accompanying the absorption of water. In the dispersed state, the seeds germinate and germinate well. On the other hand, the vegetation material,
Since the heat-fusible fibers are used as the main component and are heat-sealed in a mesh shape, even if the fibers forming the vegetation material absorb water and become in a dispersed state, heat-melting in a mesh shape is performed. In the worn part, the sprouted seeds can grow without losing the bonding strength and runoff due to rainwater or water sprinkling,
Soil quality slopes can be reliably planted. In particular,
The sheet-shaped vegetation substrate of the invention according to claim 1 of the present application is arranged such that the water-soluble paper laminated to cover the seeds is in contact with the ground, and the vegetation material located at the top when laying this. , Is pre-heat-sealed in a mesh shape, and then the seeds are bonded and held on the surface of the mesh-shaped vegetation material with a water-soluble adhesive, and a water-soluble paper is laminated to cover the seeds. Since these are joined and integrated to form a sheet, the solubility of the water-soluble paper and the solubility of the water-soluble adhesive as the binder of the vegetation material are not impeded, and the heat fusion There is no possibility that seeding will cause germination damage due to heat of seeds. Further, also in the cylindrical vegetation substrate of the invention according to claim 2 of the present application,
Before filling seeds and fertilizer, the vegetation material was heat-sealed in a mesh shape beforehand, and then the mesh-shaped vegetation material was formed into a tubular shape, so it is water-soluble as a binder for the vegetation material. The solubility of the adhesive is not hindered, and
There is no possibility that heat fusion causes germination damage due to heat of seeds.

[0008]

EXAMPLES Hereinafter, the vegetation material of the invention according to claims 1 and 2 of the present application will be described with reference to examples. FIG. 1 is a plan view showing the vegetation material, and FIG. 2 is a side view thereof. In FIGS. 1 and 2, 1 is a material for vegetation. The vegetation material 1 includes, for example, a fiber 2 made of polypropylene (PP) having a fiber length of 30 mm to 100 mm [other heat-sealable fibers such as polyethylene (PE), polyester, and vinylon may be used] as a binder. And a water-soluble adhesive (for example, polyvinyl alcohol; hereinafter referred to as PVA) 3 are bonded to form a sheet, and the weight thereof is 10 to 80 g per square meter. Then, from the front surface and the back surface, for example, 10 mm vertically and horizontally.
The mesh-like heat-sealing portions 4 are provided by linearly heating and heat-sealing at intervals of -100 mm.

As an example, FIG. 3 is a perspective view showing a method of heat-sealing the vegetation material 1 in a mesh shape to form the heat-sealing portion 4. In FIG. 3, reference numeral 20 denotes a heat fusion device. The heat fusion device 20 includes a pair of heating rollers 21 and 22 arranged in parallel with each other, and both heating rollers 21 and 22.
2, a holding portion 23 that holds the heating roller 21, a motor 24 that applies a rotational force to the heating roller 21, and gears 25 and 25 that transmit the rotational force to the heating roller 22. The heating rollers 21 and 22 are made of metal such as iron, and have mesh-like protrusions 21 on their outer surfaces.
a and 22a are projected. Then, the heating rollers 21 and 22 are rotated by the motor 24 while being heated by a heater (not shown) to press the vegetation material 1 to form the heat-sealed portion 4. Thus, the heat-sealing portion 4 is easily formed by the heat-sealing device 20. However, it goes without saying that the heat fusion of the vegetation material 1 is not limited to the above method.

In the above embodiment, the fibers 2 forming the vegetation material 1 are all made of heat-fusible chemical fibers such as polypropylene, but 30% natural fibers (rayon, etc.) are contained in the chemical fibers. The heat fusion can be performed even if mixed before and after. Needless to say, the water-soluble adhesive 3 is not limited to PVA.

Next, a sheet-shaped vegetation base (stretch grass) using the vegetation material 1 will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view showing the stretched grass body, and FIG. 5 shows a state in which the stretched grass body is installed. 4 and 5, 10
Is a stretched grass body (sheet-shaped vegetation substrate) using the vegetation material 1 of the present invention, and this stretched grass body 10 has various seeds 5 dissolved in water on the surface of the vegetation material 1 which has been previously heat-sealed in a mesh shape. The adhesive 5 is bonded and held, and a crepe paper 7, which is an example of water-soluble paper, is bonded so as to cover the seed 5, and these are bonded and integrated to form a sheet.

The stretched grass body 10 thus formed is shown in FIG.
As shown in (A), the seed 5 and the crepe paper 7 are arranged so that the surface to which they are adhered is in contact with the ground 8. When exposed to rainwater or sprinkling water, the vegetation material 1 dissolves the water-soluble adhesive 6 due to absorption of water, so that the fibers 2 are dispersed and the seeds 5 germinate and germinate well. Done.
However, in the heat-sealing portion 4, the fibers 2 constituting the vegetation material 1 do not lose their bonding strength even if they absorb water and the water-soluble adhesive 3 dissolves. In this way, the heat-welded portion 4 remains as shown in FIG. 5 (B) and prevents the germinated seed 5 from being washed away by rainwater or the like. Further, since the vegetation material 1 is heat-sealed in advance in a mesh shape, the solubility of the crepe paper 7 and the solubility of the water-soluble adhesive 3 as a binder of the vegetation material 1 are not impeded. Moreover, there is no possibility that the heat fusion causes the germination damage due to the heat of the seed 5.

Next, a columnar vegetation substrate using the vegetation material 1 will be described. FIG. 6 is a perspective view showing a vegetation mat, and 11 in the figure shows the vegetation mat. This vegetation mat 11 has a bag portion 12 provided on a mesh net 13, and a cylindrical vegetation substrate 14 is inserted into the bag portion 12.

The columnar vegetation substrate 14 is a tubular vegetation material 1 which is heat-sealed in a mesh shape in advance, and monocotyledonous or dicotyledonous seeds and fertilizer filled therein. And soil improver and water retention agent. Then, the vegetation mat 11 into which the columnar vegetation substrate 14 is inserted is attached to a slope of soil such as a hillside, whereby the vegetation material 1 absorbs water, and the water-soluble adhesive 3 is PV.
A is rapidly dissolved, and along with the dissolution of PVA, various offspring in the columnar vegetation substrate 14 are successfully sprouted from the vegetation material 1 to germinate reliably, and the soil quality slope is greened. Done. Further, since the vegetation material 1 which is one of the constituent requirements of the columnar vegetation substrate 14 has the heat-sealed portion 4 which is heat-sealed in a net shape, the heat-sealed portion 4 can be used even in rainwater. The part 4 remains to prevent seed runoff. Also,
Before filling seeds, fertilizers, etc., the vegetation material 1 was heat-sealed in a mesh shape in advance, and then the mesh-shaped vegetation material 1 was formed into a tubular shape. The solubility of the water-soluble adhesive 3 as described above is not hindered, and there is no possibility that heat fusion causes germination damage due to heat of the seeds.

[0015]

As described above, the vegetation raw material used in the sheet-shaped vegetation substrate of the invention according to claim 1 of the present application and the columnar vegetation substrate of the invention according to claim 2 of the present application contains heat as a main component. The fusible chemical fiber is formed by heat-sealing it in a mesh shape using a water-soluble adhesive as a binder, so the vegetation material retains its solubility due to the water content and seeds can be germinated reliably. The heat-welded portion forms a net-like body so that the germinated seeds can easily grow due to rainwater or water sprinkling without being washed away and greening can be surely performed while germinating. In addition, a part that is easily dissolved and dispersed by rainwater etc. in one vegetation material and a heat fusion part that holds the seeds as a water-insoluble mesh so that seeds do not run off due to rainwater etc. Since it is possible to form the vegetation, it is not necessary to separately bond a net-like body as in the conventional case, and the production cost can be reduced, and the usage of the vegetation material can be greatly expanded. In particular, the sheet-shaped vegetation substrate of the invention according to claim 1 of the present application is one in which water-soluble paper laminated so as to cover seeds is placed in contact with the ground, and the vegetation located at the top when laying this The material is heat-sealed in a net shape beforehand, and then the seeds are bonded and held on the surface of the net-shaped vegetation material with a water-soluble adhesive, and water-soluble paper is attached to cover the seeds. As a result, since the moss is integrally joined and formed into a sheet, the solubility of the water-soluble paper and the solubility of the water-soluble adhesive as the binder for the vegetation material are not both hindered, Moreover, there is no possibility that heat fusion will cause germination damage due to heat of the seeds. Further, also in the columnar vegetation substrate of the invention according to claim 2 of the present application, the material for vegetation is heat-sealed in advance in a mesh shape before being filled with the seed and the fertilizer, and then the mesh material for vegetation in a mesh shape. Since the material is formed into a tubular shape, the solubility of the water-soluble adhesive as a binder for the vegetation material is not impaired, and there is no possibility that germination damage due to heat of the seed will occur due to heat fusion. .
