Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention organically combines grass that grows quickly and is suitable for short-term greening, and trees and wildflowers that can withstand poor soil and restore mountains. This invention relates to a slope greening method that enables permanent greening.

(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 were sown could not grow, leaving only grass as greenery.Furthermore, as grass only grows for a few years, the greening would be short-term and the final goal of restoring the mountain would not be achieved. do not have.

On the other hand, attempts to prevent pressure on pastures and encourage the growth of trees and wildflowers are old, and were proposed in Special 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. Since the seeds were sown by digging, it was inefficient and uneconomical, and also had the disadvantage that the seeds were washed away by rainfall.

The present inventors have undertaken research on a labor-saving and economical slope greening method that allows for permanent greening, and has completely prevented the washing away of vegetation bags containing grass seeds, allowing them to receive pressure from grass. We have found a method that allows wildflowers and trees to grow without fail and have completed the present invention.

(Means for solving problems) The details of the present invention will be explained below based on examples.

The net 1 of the present invention, which is vertically elongated and has a large number of storage parts, can be made of any vegetable, chemical, or metal material as long as it adapts to the undulations of the slope and has enough strength to hold back soil. Chemical nets such as nylon and polyethylene are most suitable.

The general manufacturing method and form of manufacturing the net having the storage part 2 of the present invention is as shown in FIG.
This is a manufacturing method and form in which a portion that is not woven or fused to some extent is created, and the portion that is not woven or fused is used as a container for a vegetation bag or a fertilizer body.

In this case, a dense portion may be provided between the accommodating portions in a contoured manner by threads constituting the net.

Other manufacturing methods and shapes are shown in FIG.
Pinch one piece of mesh about 30cm apart at 20-60cm intervals,
There are methods and configurations in which the receptacle is created by braiding the knob portion 3 or by threading it through a rope.

Also, as shown in Figure 3, by overlapping two net-like bodies,
There is also a method and configuration in which two ropes 4 about 15 cm wide are woven together at intervals of 20 to 60 cm, and the 15 cm wide portion is used as the storage section.

Next, the fertilizer bag 6 and the vegetation bag 5 to be stored in the storage section will be explained. The fertilizer bag has a bag body made of an insoluble non-woven fabric having a thickness and air permeability that allows fertilizer nutrients to gradually seep out due to rainfall. It is quick-acting, so that the fertilizer effect continues for about 1 to 5 years.
It is effective to use a mixture of three types of fertilizers, slow-release and slow-release.If you use water retaining materials and mineral soil conditioners in addition to fertilizers alone, the decomposition of fertilizer nutrients can be further prevented over a long period of time. can be set. Regarding the vegetation bag, the material that makes up the bag is a polymeric film that dissolves in water, a starch film, or a water-soluble paper with a transparent coating (bonlic paper) so as not to hinder the germination and growth of the vegetation.
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 ropes 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.
The packaging is rolled.

The above vegetation nets are brought to the site, suspended from the top of the slope, and strung with anchor pins, nails, etc.
Once the planting is completed, the seeds are wormwood,
Seeds of wild plants such as pampas grass, medohagi, and itadori, seeds of trees such as grasshopper, yamahagi, komatsunagi, red pine, and palm yabushi, and sometimes flower seeds, fibers, organic compost, fertilizers, and soil conditioners. The construction is completed by scattering and sowing the mixed vegetation base material 7 using a power sprayer.

(Function) In the present invention, to prevent erosion on slopes in the early stages, grass put into vegetation bags grows in stripes to protect it because it grows quickly, and wild grasses and trees are scattered in other net areas. Because of this, the grass grows gradually without being under pressure from pasture.

In addition, since the vegetation bag is made of water-soluble paper, etc., even if it dissolves due to rainfall, there is no risk that the vegetation base material will be washed away downward by the fertilizer bag located at the bottom. Pressure caused by grass seeds flowing downward and getting mixed with the sowing area of wild grass seeds, tree seeds, or flower seeds can be completely prevented.

(Effects of the Invention) As described above, the present invention provides for storing grass seeds as seeds in a bag in the storage part of a vertically long net having a large number of storage parts provided at appropriate intervals. The filled vegetation bag and the fertilizer bag are filled with fertilizer inside the bag, and the vegetation net is inserted so that the vegetation bag is positioned at the top of the fertilizer bag when the net is stretched, and the vegetation net is hung down from the top of the slope. , a slope greening method capable of permanent greening, characterized in that after the completion of the planting, a vegetation base material containing one or more of wildflower seeds, tree seeds, and flower seeds is sown using a power sprayer. Therefore, it has become possible to grow grass and wildflowers, trees, or flowers completely separately.

In addition, even slow-growing wildflowers, trees, or flowers grow smoothly without being pressured by the grass, and the grass prevents the slope from forming in the early stages, so the slope can be reliably restored 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. , it has the effect of being extremely labor-saving and economical.
