Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention achieves permanent greening by combining grass that has strong growth potential and is suitable for short-term greening, and trees that can withstand poor soil conditions. This invention relates to the invention of a stretched grass body that can be restored to a mountain.

(Conventional technology and its problems) The commonly used seeding method for slope greening is mixed sowing of grasses and wildflowers and trees, but in this method, the growth power of grasses is strong and the growth of wildflowers and trees is under pressure. As a result, the wildflowers and trees that were sown are unable to grow, leaving only grass to become green, making it impossible to restore the mountain, which is the ultimate goal. Therefore, in Special Publication No. 45-25247, these grasses,
It was proposed to grow wildflowers and trees separately in contour lines.

This method is an extremely excellent invention in that it prevents pressure on pastures and allows wildflowers and trees to grow.
Recently, based on the idea of the invention of Japanese Patent Publication No. 45-25247 mentioned above, a vegetation substrate was devised for commercialization in Utility Model Application No. 114607/1983, and it was put into practical use under the trade name Vertex. ing.

(Problem to be solved by the invention) Vertex is an extremely excellent product in that it separates grass, wildflowers, and trees and prevents pressure on the grass, but it has one fatal flaw. .

All seeds, but especially wildflowers and trees, do not require fertilizer nutrients from the germination period to the early growth period, and depending on the type of fertilizer, it may be harmful.
For this reason, Verdex has a structure in which wild grass and tree seeds are placed in the lawn area, and grass seeds are filled with fertilizer into the vegetation bag.

However, since vegetation bags naturally contain fast-growing grasses, the material that makes up the bag is water-soluble paper or film, but when it rains, the vegetation base material inside the bag washes out. As a result, we observed a phenomenon in which grass seeds stopped growing in the turf and grass grew in the turf. Therefore, in order to prevent pressure on the pastures, the grass, wildflowers, and trees were separated into layers.
The initial objective could not be achieved because the grasses began to grow beyond the grass cover of the wildflowers and trees, putting pressure on the wildflowers and trees.

The inventor of the present invention focused on this point, and began research on a turf material that can reliably grow wildflowers and trees without being subjected to grass pressure, and discovered a method that can completely prevent the outflow of vegetation base material, and has invented the present invention. reached.

(Means for Solving the Problems) That is, the present invention provides a net with tensioned turf in which at least one type of wild grass seed or tree seed is stuck to the net, and grass seed is used as the seed. A vegetation bag filled with only seeds and a fertilizer bag filled with fertilizer in an insoluble bag body are placed in the same attachment part.
Moreover, when the above-mentioned turf net is stretched on a slope, the turf net is installed so that the vegetation bag is positioned above the fertilizer bag when viewed from the same mounting part, thereby ensuring permanent greening.

The details of the present invention will be explained below based on examples.

The net constituting the stretched turf body of the present invention may be made of any plant-based, chemical, or metallic material as long as it adapts to the undulations of the slope and has sufficient strength to prevent soil and sand, but nylon, Chemical net 1 such as polyethylene is most suitable.

First, in this net, at least one type of wildflower seed or tree seed is placed between water-soluble paper or nonwoven fabric, and if necessary, fertilizer, water retention agent, etc.
The soil improvement material is either a tightly bound grass 2 or cotton-like fibers such as fallen cotton, and contains at least one type of wildflower seed or tree seed, as well as fertilizer, water retention agent, etc. as necessary.
A grass turf 2 mixed with vegetation materials such as soil conditioners is attached. This pasting of grass to the net may be performed after attaching fertilizer bags and vegetation bags to the net, which will be described below.

Next, the fertilizer bag 4 and vegetation bag 3 to be attached to the grass net will be explained.

The fertilizer bag is made of an insoluble non-woven fabric with a thickness and ventilation that allows the fertilizer components to gradually seep out due to rainfall. It is effective to use a mixture of three types of fertilizers: fast-release, slow-release, and delayed-release fertilizers.Instead of using fertilizer alone, using a water retention agent and a mineral soil conditioner together can further decompose fertilizer nutrients over a long period of time. can be extended to.

Vegetation bags are made of polymeric film or starch film that dissolves in water so as not to hinder the germination and growth of vegetation. The bag is filled with only grass seeds. Furthermore, water retention agents, soil conditioners, and fertilizers are also added as needed.

The above fertilizer bag and vegetation bag are installed at appropriate intervals on the grass net, and the vegetation bag and fertilizer bag are installed in the same attachment part, and when viewed from the same attachment part, the vegetation bag is positioned above the fertilizer bag. Thus, the stretched grass body of the present invention is completed.

The vegetation bags and fertilizer bags may be attached by simply attaching them to the nets of the turf net with vinyl-coated iron wire 6 or strings, or by attaching them at appropriate intervals in the lateral direction of the mesh of the nets as shown in Figure 2. In some cases, the bag is passed through the bag vertically, and the ends of the bag are secured with staples or the like. There are various other methods, and the method is not limited to the above two methods.

The size of this stretched grass body is usually 1m in width and 5 to 50cm in length.
The length is 10m, and the packaging is rolled.

FIG. 3 shows a state in which the stretched turf body of the present invention is stretched on a slope 20, and the turf is stretched with the turf facing downwards using anchor pins 5 or pegs.

(Effects of the Invention) As described above, the present invention provides a net with a tensioned turf in which at least one type of wild grass seed or tree seed is stuck to the net, and only grass seeds are used as the seed. If a vegetation bag filled with fertilizer and a fertilizer bag with an insoluble bag body filled with fertilizer are viewed from the same mounting part, and when the above-mentioned turf net is stretched on a slope, the vegetation bag Since it is a turf body that is installed so that it is positioned above the fertilizer bag and can ensure permanent greening, it is possible to grow grass, wildflowers, and trees completely separately. In addition, conventional products that separate grass from wild grass and trees to prevent grass pressure and ensure the growth of wild grass and trees have been developed, but the vegetation bag containing the grass breaks and the wild grass grows. However, even though the grasses were separated from the grasses and the trees, the grasses were under pressure and the wildflowers and trees were unable to grow.
In the stretched turf body of the present invention, the fertilizer bag is placed under the vegetation bag containing the grass, so even if the vegetation bag is torn, the fertilizer bag prevents the grass seeds from flowing out, allowing wildflowers and trees to grow.

Therefore, early afforestation is accomplished in a contoured manner by the grass filled in the vegetation bags, and wildflowers and trees grow smoothly without being pressured by the grass, allowing the mountains to be restored, which is the ultimate goal of afforestation. .
