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) The commonly used seeding method for slope greening is mixed sowing of grasses and wildflowers and trees. The drawback is that the wildflowers and trees that have been sown are unable to grow, leaving only the pastures to become green, and the ultimate goal of restoring the mountains cannot be achieved. For this reason, it was proposed in Special Publication No. 45-25247 to grow these grasses, wildflowers, and trees separately in contour lines.

This method is an extremely excellent invention in that it allows wild grasses and trees to grow while preventing pressure on pastures. Recently, based on the idea of the invention of the above-mentioned Japanese Patent Publication No. 45-25247, a vegetation substrate was devised in Utility Model Application Publication No. 14607-1987 to commercialize 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, 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. ing.

All seeds, but especially wildflowers and trees, do not need 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 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. A phenomenon was observed in which the grass seeds stopped in the stretched grass area and the grass grew in the stretched grass area. Therefore, in order to prevent pressure on the pastures, we separated the grass, wildflowers, and trees into layers, but the grass grew from the grassy part of the wildflowers and tree layer, and grew faster than the grassy part of the wildflowers and tree layer. The initial objective could not be achieved because the grass grew and overwhelmed the wildflowers and trees.

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

(Means for Solving the Problems) That is, the present invention comprises a net having storage portions provided at appropriate intervals, and a sod having at least one type of wildflower seeds and tree seeds stuck thereon. Vegetation materials such as water retaining materials and fertilizers, as well as vegetation bags filled with only grass seeds, are stored in the same storage part of the net, and when the net is stretched on a slope, the same storage part is used. When viewed from the outside, it is a turf structure for permanent greening in which a vegetation bag is inserted above a fertilizer bag.

The details of the present invention will be explained 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 adapts to the undulations of the slope and has enough strength to prevent soil and sand, but nylon, Chemical net 1 such as polyethylene 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 approximately 1.2 cm is created that is not woven or fused, and this 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 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 receiving part is made by braiding the knob part 3 or by passing a rope through it.

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

In the net having the accommodating parts shown in FIGS. 1, 2, and 3 above, at least wild grass seeds and tree seeds are placed between water-soluble paper or nonwoven fabric as shown in FIG. 4. The grass turf 7 is made by pasting one or more types of grass, or the grass 7 is a mixture of only wild grass seeds and tree seeds as seeds in cotton-like fibers such as fallen cotton. At this time, if necessary, vegetation materials such as fertilizers, water retention materials, and soil improvement materials are applied or mixed.

Next, to explain the fertilizer bag 6 and the vegetation bag 5 stored in the storage section, 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, and the bag body is is fast-acting, so that the fertilizer effect lasts continuously 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 improved over a long period of time. can be set.

Regarding the vegetation bag, the material constituting the bag body is composed of water-soluble polymer film, starch film, or water-soluble paper with canola sheath (Bonric product name, Kinsei Paper Co., Ltd.). The container is filled with only grass seeds and other vegetation materials such as water retaining material and fertilizer.

When the above-mentioned fertilizer bag and vegetation bag are placed on the slope in the storage area of the net, if the vegetation bag and the fertilizer bag are placed in the same storage area, and when viewed from the same storage area, the fourth bag should be positioned above the vegetation bag. Insert it as shown in the figure to complete the tensioned turf body of the present invention.

The net that makes up the turf body has ropes for reinforcement on both sides 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 a situation in which the stretched turf body of the present invention is installed on a slope 20, and the turf is normally placed on the lower side using anchor pins, pegs, etc.

(Effects of the Invention) As described above, the present invention includes a net in which storage portions are provided at appropriate intervals, and a sod having at least one type of wildflower seeds and tree seeds stuck thereon.
In the storage section of the net, a vegetation bag filled with only grass seeds and vegetation materials such as water retaining material and fertilizer, and a fertilizer bag filled with fertilizer in an insoluble bag body are placed in the same storage section. When the above-mentioned net is stretched on a slope, when viewed from the same storage area, the grass bag is inserted so as to be positioned above the fertilizer bag, and it is a turf body for permanent greening, so grass, wildflowers, and trees can be completely removed. It is possible to grow them separately. Moreover, conventional products that separate grass, wildflowers, and trees to prevent pressure on the grass and ensure the growth of wildflowers and trees have been developed, but the vegetation bag containing the grass breaks, causing the wildflowers to grow. However, even though we separated the grass that leaked into the tree layer from the wild grass and trees, the grass put pressure on the wild grass and trees and the wild grass and trees could not grow. Since the fertilizer bag is placed under the ivy vegetation bag, even if the vegetation bag is torn, grass seeds are prevented from flowing out due to the fertilizer bag, allowing wildflowers and trees to grow.

Therefore, early afforestation is achieved in contour lines by the grass filled in the vegetation bags, wildflowers and trees grow smoothly without being pressured by the grass, and the mountains can be restored, which is the ultimate goal of afforestation. .
