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 turf body that can be restored to the mountain.

(Conventional technology) The commonly used seeding method for slope greening is mixed sowing of grasses, wildflowers, and trees.
The strong growth of grasses puts pressure on the growth of wildflowers and trees, leaving the sown wildflowers and trees unable to grow, resulting in only grasses becoming green, making it impossible to restore the mountains, which is the ultimate goal. There are drawbacks. Therefore, in Special Publication No. 45-25247,
It was proposed to grow these grasses, 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 in Utility Model Application Publication No. 60-114607 with the aim of commercializing it, and it was put into practical use under the trade name Vertex. has been done.

(Problem to be solved by the invention) By the way, this vertechus grows grasses, wildflowers,
Although it is an excellent product in that it separates trees and prevents secret pressure on grass, 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. The structure is such that wild grass and tree seeds are placed in the lawn area, and grass seeds are filled with fertilizer into the vegetation bag.

However, although vegetation bags contain fast-growing grasses, the material that makes up the bag is water-soluble paper or film, so when it rains, the vegetation base material inside the bag is washed away. 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 grass, grass, wildflowers, and trees are separated into layers, but the grass grows from the grass part of the wildflower and tree layer and puts pressure on the wildflowers and trees. Therefore, the initial objective could not be achieved.

The inventors of the present invention focused on this point, and began research on a turf structure that would allow wildflowers and trees to grow reliably without being pressured by pastures. The invention has been achieved.

(Means for Solving the Problems) That is, in the present invention, a pine on which wild flowers and trees can germinate and grow is stuck to a net having storage portions provided at appropriate intervals, and the pine can contain wild grass seeds. ,
At least one kind of tree seeds are glued together using a water-soluble glue, and the storage part of the net contains:
Permanent greening is possible by inserting a vegetation bag filled only with grass seeds and a fertilizer bag filled with fertilizer in an insoluble bag so that the vegetation bag is positioned above the fertilizer bag when the net is stretched. The body is made of solid wood.

The present invention will be described in detail below based on examples.

The net having the housing part of the present invention may be made of any plant-based, chemical, or metallic material, as long as it conforms to the undulations of the slope and has sufficient strength to prevent soil and sand. A chemical net 1 such as , polyethylene or the like is most suitable.

The general manufacturing method and configuration for manufacturing the net having the housing portion 2 of the present invention are as shown in FIG.
Layer 2 sheets of chemical nets, 15 at intervals of 20 to 60 cm.
This is a manufacturing method and form in which a portion of about 1.2 cm is made that is not woven or fused, and the portion that is not woven or fused is used as a container for a vegetation bag or fertilizer bag.

In this case, a dense portion may be provided in contour lines between the accommodating portions and the threads constituting the net.

Other manufacturing methods and configurations include, as shown in FIG. 2, a method and configuration in which a single net-like body is pinched at intervals of about 30 cm at intervals of 20 to 60 cm, and the grip portions 3 are knitted or roped through to form a storage section.

In addition, as shown in Figure 3, two net-like bodies are stacked on top of each other, and two ropes 4 are placed about 15 cm wide at intervals of 20 to 60 cm.
There is also a method and form in which this 15cm wide part is used as a storage part.

As shown in FIG. 4, a mat 7 made of cotton-like fibers or a non-woven fabric or a water-soluble Attach pine that can germinate and grow plant seeds such as paper.

Next, wild grass seeds and tree seeds are sown on the pine as seeds, either alone or in a mixture of one or more types of wild flower seeds and tree seeds, and then glued together with a water-soluble glue. At this time, vegetation materials such as fertilizer, water retaining material, soil improvement material, etc. are attached as necessary.

This adhesion of seeds onto the pine may be carried out after the fertilizer bag and vegetation bag described below are placed in the storage section of the net.

Next, the fertilizer bag 6 and the vegetation bag 5 to be stored in the storage section.
To explain this, the bag body of a fertilizer bag is made of an insoluble non-woven fabric with a thickness and ventilation that allows fertilizer nutrients to gradually seep out due to rainfall. As described below, it is effective to use a mixture of three types of fertilizers: fast-release, slow-release, and slow-release fertilizers.In addition to using fertilizer alone, using water retaining materials and mineral soil conditioners together can further improve the fertilizer nutrients. decomposition can be sustained over a long period of time.

Regarding the vegetation bag, the material constituting the bag body is composed of water-soluble polymer film, starch film, or water-soluble paper with cannula shea (Bonric, trade name, Ikeda Shigyo Co., Ltd.). The bag is filled with only grass seeds. Furthermore, fill with water retaining material, soil conditioner, and fertilizer as necessary.

The lawn structure of the present invention is completed by inserting the above-mentioned fertilizer bag and vegetation bag into the accommodating part of the net so that the vegetation bag is positioned above the fertilizer bag when the slope is stretched over the slope as shown in FIG.

The net that makes up the turf body is provided with ropes for reinforcement at both ends and sometimes in the center, and is usually 1 m wide and 5 to 10 m long, and is packaged in rolls.

FIG. 5 shows the situation in which the stretched turf body of the present invention is installed on a slope 20. Usually, the turf is stretched with the pine facing downwards using anchor pins, pegs, etc.

(Effects of the Invention) As described above, according to the present invention, a pine on which wild flowers and trees can germinate and grow is stuck to a net having storage portions provided at appropriate intervals, and the pine can contain seeds of wild flowers and trees. At least one kind of seeds are glued together with a water-soluble glue, and the storage part of the net includes a vegetation bag filled only with grass seeds and a fertilizer body filled with fertilizer in an insoluble bag body. When the net is stretched, the vegetation bag is inserted above the fertilizer bag, allowing for permanent greening, making it possible to grow grass, wildflowers, and trees completely separately. be. 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 were available, but the vegetation bags containing grass seeds were torn. However, even though we separated the grass seeds that leaked into the wild grass and tree layer from the wild grass seeds and tree seeds, the pressure was applied to the wild grass and trees by the grass, and the wild grass and trees were unable to grow. The lawn structure has a fertilizer bag placed under the vegetation bag containing grass seeds, so even if the vegetation bag is torn, the fertilizer bag will prevent the grass seeds from flowing out.
Wildflowers and trees can grow.

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