Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation covering material such as a vegetation mat used for protecting a ground surface such as a hillside slope and a cut slope, and a vegetation base material used therefor.

[0002]

2. Description of the Related Art As the above-mentioned vegetation mat, a vegetation mat in which a paper sheet in which seeds are sandwiched on a covering material (net of polyethylene or the like) is polymerized has been proposed before. Furthermore, a fertilizer bag filled with fertilizer in the storage part provided in the covering material,
There has also been proposed a configuration in which a vegetation base material such as a vegetation bag containing seeds is mounted.

According to the former vegetation mat, the seeds sandwiched between the paper sheets can germinate and grow by rainfall, protect the ground, and achieve greening. Therefore, the vegetation mat is widely used for vegetation greening. It is used in the field. And when the latter vegetation mat is equipped with a fertilizer bag as a vegetation base material, compared to the former vegetation mat,
The fertilizer bag effectively promoted plant growth and enabled greening in an environment unsuitable for vegetation. In addition, by mounting the vegetation bag, it is possible to separate the plants of the paper sheet part from the plants of different types, so that greening by various plants has been enabled.

Particularly in the latter vegetation mat, the above-mentioned effect can be promoted because the usually cylindrical vegetation base material blocks soil particles and seeds introduced by rainfall.

However, foams such as vermiculite are usually stored in the storage material for the purpose of fertilizing / water retention and maintaining the cylindrical shape of the vegetation base material. Due to early shrinkage due to quality, the vegetation base material often becomes flat and the initial effect cannot be sustained.

[0005] From the above, in the present invention, the vegetation for the vegetation, which is capable of maintaining the shape for a long time and maintaining the damming effect of suppressing runoff of the introduced seeds while maintaining the shape for a long period of time, is devoted to the present invention. It is an object of the present invention to provide a substrate and a vegetation covering material provided with the substrate.

[0006]

That is, the vegetation base material of the present invention comprises a seed, fertilizer, fertilizer,
A vegetation base material filled with at least one vegetation material such as a soil improvement material and a plant growth promoter is characterized by containing coarse fibers together with the vegetation material (claim 1).

[0007] As a housing material having air permeability or water permeability or weakened with the passage of time to allow ventilation or water permeability,
Highly durable paper or non-woven bags can be mainly applied.

[0008] As coarse fibers to be accommodated in the vegetation substrate,
For example, at least one of tree foliage, wood chips, shredder dust, plant foliage such as straw, unraveled bark, and unraveled fiber is selected (claim 2). When a material derived from a tree is selected, the porosity of the fiber itself also contributes to heat retention and humidity control, and is therefore beneficial and desirable for plant growth. Above all, wood wool has the highest effects obtained from the shape retention and the above-mentioned effects, and is therefore desirable.

Further, the vegetation covering material of the present invention is characterized in that at least the vegetation base material according to claim 1 is attached to the covering material covering the ground surface (claim 3).

As the coating material, palm nets and palm mats using hemp fibers, which are corrosive vegetable fibers, hessian cloth (hemp woven fabric), straw mats, light cotton, fiber waste mats, and fibers that are easily treated with water Is a non-woven fabric, for example, PV
Non-woven fabric containing A (polyvinyl alcohol) fiber, P
VA film, paper, especially water-disintegrated paper and the like are preferably used, but may be a net or film made of biodegradable or corrosion-resistant synthetic resin fiber.
It is appropriately selected and used so as to obtain a desired strength of the covering material for vegetation.

[0011] The vegetation base material is preferably attached to the vegetation covering material in the form of a contour in a tubular bag, but may also be attached as a connected body of small bags. In addition, a housing portion having air permeability or water permeability, or having a property of being weakened with time and allowing ventilation or water permeability may be appropriately formed on the covering material to be used as a housing material.

When the target area for vegetation protection is a snowy area,
To prevent damage due to avalanches and frost heaves, a reinforcing net is preferably provided on the vegetation covering.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a vegetation base material, and FIG.
Shows an example of a vegetation covering material.

In FIG. 1, a vegetation substrate 1 is made of a hydrolyzed paper 5
Cylindrical housing material 4 formed by laminating the net 6 and the net 6
Inside (for example, thickness: 2 to 10 cm, length: about 1 m), a coarse fiber 3 and a vegetation material 2 such as a seed, a fertilizer, a soil improvement material, and a plant growth promoter are housed. . When a fertilizer, a soil conditioner, or a plant growth promoter is selected in the vegetation material 2, the active ingredient leaks from the water-permeable paper 5 together with rainfall, and effectively acts on vegetation. As the fertilizer, immediate-acting or slow-acting or a mixed fertilizer thereof is used. Vermiculite or a highly water-absorbing resin, which enhances the fertilizing power and water retaining power, is used as the soil improving material. Commercially available germination promoters and the like are used as the plant growth promoter. In addition, when seeds are selected in the vegetation material 2, the hydrolyzed paper 5 is weakened by the time the seeds germinate, and does not hinder the germination. Further, while the net 6 grips and stabilizes the vegetation material 2, while the coarse fibers 3 maintain the shape of the vegetation base material,
It protects the growth of the introduced vegetation by its heat and moisture retention.

As the coarse fibers 3, at least one of plant foliage such as wood wool, wood chips, shredder dust, straw, broken bark, and broken fiber is preferably used. Of these, wool, wood chips and bark can be obtained at low cost by using thinned wood and fallen timber.

These effects can be effectively obtained even if the vegetation base material 1 is not cylindrical, for example, even if the sachets are connected to each other. However, the effect of damming soil particles and seeds can be maximized. Is preferably cylindrical.

When the vegetation base material 1 is installed on a slope, the vegetation base material 1 is appropriately fixed with anchor nails or the like. In this case, it is preferable to install in combination with a covering material such as a net that covers the ground surface because the effect of protecting the slope is high. The tubular vegetation base material 1 is
It is preferable to install in parallel with the contour line.

Further, as shown in FIG. 2, the vegetation base material 1 is provided at least with the covering material 8 covering the ground surface.
Is pre-mounted on the vegetation covering material 7 to facilitate installation work on site. The vegetation covering material 7 shown in FIG. 2 is, for example, about 1 m in width and 5 to 10 m in length. The vegetation base material 1 is attached to the storage section 10. The sheet 9 with seeds such as grass and trees is polymerized to enable greening. Vegetation substrate 1
May be fixed to the covering material 8 by bonding, staple, bundling or the like.

As the covering material 8, palm nets and palm mats using coco fiber, which is a corrosive plant fiber, hessian cloth (hemp woven cloth), straw mat, thin cotton, fiber waste mat,
Nonwoven fabric in which fibers are easily dispersed by water, for example, P
Non-woven fabric containing VA (polyvinyl alcohol) fiber,
PVA films and papers, especially water-disintegrated papers are preferably used, but nets or films made of biodegradable or corrosion-resistant synthetic resin fibers may be used. In order to obtain the strength of material 7,
What is necessary is just to select and use suitably. At this time, depending on the product, if there is a concern that the passage of the germ is difficult,
A slit or the like may be formed.

When seeds such as foreign grasses and trees are introduced into the sheet 9 with seeds, uniform greening is achieved at an early stage. Also, when germination and growth of buried seeds are expected without using the sheet 9 with seeds, the effect of damaging the topsoil by the vegetation base material 1 is high, and although it takes time, greening by latent vegetation can be achieved.

Further, as another embodiment, the covering material 8 made of a net, for example, is partially formed so as to have air permeability or water permeability, or to be weakened with time and to have a property of allowing ventilation or water permeability. Weaving it to a small size to form a storage part,
The portion may be used as a housing material to house seeds, fertilizers, soil improvement materials, plant growth promoters, and coarse fibers.

In the case of a snowy area in particular, covering the vegetation covering material 7 with a reinforcing net having a high tensile strength (for example, a geogrid made of synthetic resin or a metal net) may cause damage due to an avalanche or frost heave. This is preferable in preventing

Further, when the vegetation base material 1 is configured to be large so as to have a width of about 40 cm, a length of about 60 cm, and a thickness of about 10 cm,
Applicable as sandbag. At this time, a net material having a small mesh size such as polyethylene is preferable as the storage material, and can store a large amount of coarse fibers 3 in addition to the vegetation material 2 and is excellent in portability as compared with ordinary sandbags. it can. It is also possible to contain soil such as locally generated soil.

As described above, according to the present invention,
In the vegetation base material, the function of keeping heat and moisture was exhibited, and at the same time, the shape was maintained for a long time, and the damming effect of suppressing the runoff of the topsoil and introduced seeds was able to be maintained. In addition, by attaching the vegetation base material having the above-mentioned effects, a vegetation covering material in which runoff of the topsoil and introduced seeds was effectively suppressed could be obtained.
