Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vegetation base for use in difficult-to-vegetate areas, such as bedrock, which can form a thick vegetation base by simply stretching the base.

Recently, there has been a need to revegetate areas where vegetation is difficult to grow, such as bedrock, and this has been achieved by spraying to form a thick base layer of vegetation.

However, when forming a thick base layer of vegetation by spraying, the sprayed material must be sprayed with a hardened material, otherwise the sprayed material will be washed away. The spraying is done using a machine that can be used.

To perform this spraying, a spray gun, compressor,
Various types of machinery such as generators, belt conveyors, batchers, etc. are installed at the site, and construction and transportation of these machines requires a large amount of money, making it a large-scale facility even if the area is small. It has the disadvantage of being

In addition, if a thick vegetation base layer is formed, the vegetation base layer may be washed away by rainfall, so cement is used as a glue. There is also the drawback that the adjustment of the amount of cement is delicate and difficult, as if a small amount of cement is used, it will wash away.

In addition to the method of forming a vegetation base by spraying as described above,
As a method that requires relatively little mechanical power, a bag capable of containing vegetation base material is placed on the slope in advance, and a squeeze pump is used to transport the vegetation base material and fill it into the bag, creating a thick layer of vegetation. There is also a method of forming a mat, but since this method involves filling the bag with vegetation base material, it is difficult to follow the undulations of the slope, and the vegetation base layer and the ground do not become integrated. However, there is a phenomenon in which the roots of plants do not go down into the ground, so the slope is not completely protected.

The present invention was invented in view of the above circumstances, and provides a vegetation base that can form a thick vegetation base layer by a simple method of simply laying the ground, and in which the ground and the vegetation base layer are integrated. It is intended to.

The configuration of the present invention will be explained in detail below based on the drawings.

First, the configuration of a net-like body having accommodating portions will be described, in which the accommodating portions are provided at appropriate intervals in the net-like body.

The mesh material may be made of vegetable, chemical, or metallic wires, as long as it conforms to the undulations of the slope and has the ability to suppress soil. It is easiest to create a storage part in a net-like body made of fibers.

The general manufacturing method and shape of the net-like body having the housing portion of the present invention are as shown in FIG. This is a manufacturing method and form in which a portion that is not woven or fused is made into the housing portion 2 of the cylindrical bag.

Other manufacturing methods and configurations include, as shown in Figure 2, one net-like body 1 is held at intervals of 4 to 40 cIrL by 30 (approximately 11,771) pinches, and the knob portions 3 are knitted, passed through a rope, or fused. There are methods and shapes for making part 2.

Further, as shown in FIG. 3, there is a method in which two net-like bodies 1 are overlapped and the two net-like bodies are woven together with ropes 4 at appropriate intervals, and the space between the two net-like bodies is used as a storage section. There is also a shape.

Furthermore, in order to form a storage part with a wire mesh, in a diamond-shaped wire mesh that is constructed by sequentially entangling and locking a bent part on one side with another bent part, from one bent part to another bent part at appropriate intervals, The linear section following the section is mountain-folded to form a hollow section, and this hollow section is used as a housing section for the cylindrical bag.

A water-fragile sheet is a water-soluble film such as a polymer film or a starch film that dissolves in water, or a water-soluble paper.

This water-fragile sheet is as strong as cloth or non-woven fabric under normal conditions, but once it comes into contact with water, it becomes brittle and begins to melt.

This water-fragile sheet is sewn together to form a cylindrical bag, and a vegetation base material is filled into this to form a cylindrical bag 5 made of the water-fragile sheet.

The vegetation base material to be filled into the cylindrical bag made of the water-fragile sheet is one or more of water retention materials, clay minerals, organic materials, soil improvement materials, and fertilizers that will eventually form the vegetation base layer.
Sometimes seeds are also added.

When a cylindrical bag made of this water-fragile sheet is subjected to rainfall, the water-fragility sheet begins to melt and the vegetation base material inside flows out.

Insoluble sheets are materials such as non-woven fabric, cloth, paper, etc.
Although it is insoluble, it is made of a material that gradually dissolves when the fertilizer, soil conditioner, and other vegetation base materials filled inside become a solution, and preferably have a thickness of 0.1 to 3.0 mm. ,
A nonwoven fabric with an air permeability of 10 to 300 CC/CIfL/sec is most suitable.

This insoluble sheet is sewn together to form a cylindrical bag, which is then filled with a vegetation base material to form the insoluble sheet cylindrical bag 6.

The vegetation base material placed in the insoluble sheet has a fertilizer effect of 3 to 4.
Super slow-release fertilizer that is effective for a year, slow-release fertilizer that is effective for 1 month to 2 years, and CDU that is effective for about half a year.

These include slow-release fertilizers such as ivy nitrogen, quick-release general compound chemical fertilizers, water retaining materials, clay minerals, soil improvement materials, etc. These can be packed singly or in a mixture of one or more types into a cylindrical bag made of insoluble sheets. That's what I do.

The cylindrical bag 5 in which the water-fragile sheet is filled with a vegetation base material and the cylindrical bag 6 in which an insoluble sheet is filled with a vegetation base material are stored alternately or appropriately arranged in the storage section of the net-like body. Then, the vegetation substrate for use with difficult vegetation to be used in the present invention is completed, and the completed part is shown from the front.
In this case, reinforcing ropes 8 are provided at both ends and in the center.

Normally, seed paper 7 is pasted on this vegetation substrate, or seeds and fertilizers are directly pasted with a water-soluble glue, or a thin cotton sheet is pasted and a water-soluble glue is applied on top of the thin cotton sheet. Seeds and fertilizers are attached to the area to create a form that can be used for greening the entire area.

Figure 6 shows this vegetation substrate for difficult-to-plant plants stretched on the slope 20. When it rains, the seed paper first adheres to the ground and the plants begin to germinate and grow. ,
The cylindrical bag made of the water-fragile sheet melts and the filled vegetation base material flows out and becomes the vegetation base 9, and as shown in FIG. 7, it is retained by the cylindrical bag made of the insoluble sheet and does not flow away.

This is the reason why a thick vegetation base can be formed without spraying.

As described above, the present invention comprises a water-fragile sheet bag body in which storage portions are provided at appropriate intervals in a net-like body, and a vegetation base material is filled in a bag body constituted by a water-fragility sheet, and an insoluble sheet. This is a vegetation substrate for use in areas where vegetation is difficult to grow, which is made by appropriately arranging and housing an insoluble sheet bag filled with a vegetation substrate in the housing portion of the net-like body, so that it is possible to simply stretch the vegetation substrate. Even without a large-scale mechanical plant,
It is very economical as it forms a thick layer of vegetation base.

In addition, the formed vegetation base layer is formed by the flow of the vegetation base material from the cylindrical bag made of the water-fragile sheet, so it becomes integrated with the ground and the cylindrical bag made of the insoluble sheet. Since it does not become attached to the body and be washed away by rain, there is no need to use base materials such as cement that are harmful to the growth of plants, and therefore the germination and growth of plants is extremely smooth.
