Abstract

PURPOSE:To permit permanent vegetating work of slope by a method in which a vegetating bag packed with seeds of grass and a fertilizer bag are housed at a proper interval in a net, and the net is laid on slope and a vegetating base with the seeds of wild grass and tree, etc., is spread over them. CONSTITUTION:A vegetating bag 5 packed with grass seeds, a humectant, and some fertilizer and a fertilizer bag 6 with a mixture of three kinds (fast-acting, slow-acting, and delayed acting) of fertilizers are housed in the housing part 2 formed at an adequate interval in a net 1. The net 1 is hung down from the upper part of slope and fixed with anchor pins, nails, etc., and a mixture of wild seeds, tree seeds, or flower seeds with fibers, organic compost, fertilizer, and soil stabilizer is sprayed onto the net. The erosion of the slope can thus be prevented by the grass growing at fast pace and the slopes can be recovered to hills by the growth of wild grass and tree, etc.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to fast-growing and short-term greening (grass suitable for this purpose).
This invention relates to the invention of a slope greening method that enables permanent greening by organically combining trees and wildflowers that can withstand wasteland and restore mountains.

(Conventional techniques and their problems) Recently, various government agencies such as the Ministry of Construction, the Ministry of Agriculture, Forestry and Fisheries, the National Highway Corporation, and the civil engineering departments of each prefecture have traditionally believed that the final purpose of greening is to restore the slope to its original state. One recommendation has been made for greening only pasture.

However, since the commonly used slope greening method involves spraying a mixture of grass, wildflowers, and tree seeds, the growth potential of the grass is overwhelmed by the slow-germinating and slow-growing wildflowers and trees, resulting in pressure. However, the wild grasses and trees that had been sown could not grow, leaving only grass as greenery.Furthermore, since grass only grows over a period of several years, it becomes a short-term greening, and the ultimate goal of restoring the mountains cannot be achieved. .

On the other hand, attempts to prevent pressure on pastures and encourage the growth of trees and wildflowers are old, and were proposed in Japanese Patent Publication No. 25247-1972.

This method is a method of growing grass, wildflowers, and trees separately in contour lines, and is extremely excellent from a technical perspective, but in order to sow the seeds in layers on the slope, trenches are manually dug. Since the method involved sowing seeds, it was inefficient and uneconomical, and it also had the disadvantage that the seeds were washed away by rainfall.

The present inventors have begun research on a labor-saving and economical slope greening method that enables permanent greening, completely preventing the washing away of vegetation bags containing grass seeds, and reducing pressure on grass. without receiving
The present invention has been completed by discovering a method that allows wild flowers and trees to grow reliably (means for solving problems).The details of the present invention will be explained below based on examples.

Net (1) of the present invention that is vertically long and has a large number of storage parts
The net may be made of vegetable, chemical, or metal material, as long as it is strong enough to penetrate the undulations of the slope and has the ability to absorb soil. most suitable.

The general manufacturing method and configuration for manufacturing the net having the storage portion (2) of the present invention are as shown in FIG. 1! ¥! This is a method in which two layers of plastic net are overlapped to create a 15 cm portion at intervals of 20 to 60 cm that is not woven or fused, and the portion that is not woven or fused is used to store vegetation bags or fertilizer bodies. This is the manufacturing method and shape.

In this case, a dense area may be provided between the accommodating parts in a contour line with threads forming a 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 20 to 600 m at intervals of about 30 cm, and the tab portions (3) are knitted or lobed through to create a storage section.

In addition, as shown in Fig. 3, two net-like bodies are overlapped to form a 20 to 6
There is also a method and form in which two lobes (4) about 15 cm wide are knitted at 0 cm intervals, and this 15 cm wide part is used as a storage part.

Next, the fertilizer bag (6) and planting soil bag (5) (
To explain the trick, 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. In order to follow this, it is effective to use a mixture of three types of fertilizers: fast-acting, slow-release, and slow-release fertilizers.In addition to using fertilizers alone, using water retaining materials and mineral soil conditioners together can further improve the fertilizer nutrients. can be decomposed over a long period of time. Regarding the vegetation bag, the material that makes up the bag is a polymeric film that dissolves in water, a starch film, or water-soluble paper with crystals (Ponric...trade name, Ikeda Shigyo Co., Ltd.), and the bag is filled with grass seeds, water retaining material, and some fertilizer. The vegetation net of the present invention is completed by inserting the fertilizer bag and the vegetation bag as shown in FIG. 4 so that the vegetation bag is located above the fertilizer bag when stretched over the slope in the storage part of the net.

The net that constitutes the vegetation net of the present invention is provided with lobes at both ends and sometimes in the center for reinforcement, and the size is usually 1 to 2 m in width and 10 to 30 m in length, and the packaging is rolled. do.

Deliver the above vegetation net to the site, hang it from the top of the slope, and tighten it with anchors, nails, etc.

Once the setting is complete, the seeds are seeds of wild plants such as mugwort, pampas grass, medohagi, and itadori, and seeds of trees such as grasshopper, yamahagi, komatsunagi, red pine, and yashabushi, and sometimes flowers. The construction is completed by scattering and sowing the vegetation base material (7) in which seeds are mixed with fiber, organic compost, fertilizer, and soil conditioner using a power sprayer.

(Function) In the present invention, to prevent erosion on the slope in the initial stage, the grass put in the vegetation bag is protected by growing in stripes because it grows quickly, and wild grasses and trees are scattered in the other net parts. Because of this, the grass grows gradually without being affected by pasture pressure.

Also, since the vegetation bag is made of water-soluble paper, etc., even if it dissolves due to rain, the vegetation base material remains at the bottom.
There is no risk of the fertilizer bag flowing downwards, thus completely preventing overpressure caused by grass seeds flowing downwards and contaminating the sowing areas of wildflower seeds, tree seeds, or flower seeds. Possible (Effects of the Invention) As described above, the present invention is capable of injecting grass seeds as seeds into a bag in the storage section of a net having a plurality of storage sections provided at appropriate intervals in a vertically long net. The filled vegetation bag and the fertilizer bag are filled with fertilizer inside the bag, and when the net is stretched, the vegetation net is inserted so that the soil bag is positioned one inch above the fertilizer bag, and the vegetation net is suspended from the top of the slope. A slope capable of permanent greening, characterized in that, after the completion of the planting and stretching, a vegetation base material containing one or more of wildflower seeds, tree seeds, and flower seeds is sown using a power sprayer. Because it is a greening method, it is now possible to grow grass and wildflowers, trees, or flowers completely separately.

Moreover, even wild grasses, trees, and flowers with different growth rates grow smoothly without being pressured by grass, and the grass prevents the slope from forming in the early stages, so it is possible to reliably restore the slope to a mountain.

Furthermore, since the process is as simple as hanging a long vegetation net from the top of the slope and spraying the seeds with a powered sprayer, there is no need to cut grooves as in conventional construction methods. Therefore, it is extremely labor-saving and also has an economical effect.
