Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening method by spraying on slopes and slopes, which is excellent in adhesion to the ground and sprays at a spraying thickness suitable for germination, and the growth base is dried. The present invention relates to a greening method that suppresses and improves the physical properties of the base.

[0002]

2. Description of the Related Art Conventionally, when a plant is introduced in a revegetation work on a slope or slope, a base material mixed with a growth base material and seed is sprayed, or a net or a bag to which seed or fertilizer is attached or sealed is used. An introduction method is used in which the surface is attached to the surface or the growth base material is sprayed on the surface.

[0003]

However, in recent years, since slope greening mainly consists of exotic herbaceous plants, stable slope
It has been shifting to those mainly composed of woody plants having excellent effects such as early recovery of ecosystem and harmony with surrounding landscape, and the woody plants are capable of germinating cover soil compared to exotic herbaceous plants. Since the germination conditions and growth conditions are limited such that the thickness is thin and the surface of the growth base layer does not germinate due to drying, the conventional greening method has a problem such as a reduced germination rate.

That is, according to the conventional method of mixing and spraying the growth base material and the seed, if the spraying thickness is large,
The seeds in the lower part of the growth base could not germinate due to the thick soil cover, and it was unavoidable that most of the seeds used were wasted. In addition, as a result of using a base material containing a bonding material (corrosion preventive material) such as cement or polymer resin in order to enhance the erosion resistance of the created growth base, the base becomes hard and the pH becomes high, and Germination and growth of this plant were hindered.

Further, large-sized seeds remarkably rebound during spraying, causing a considerable loss during construction, which is a problem that cannot be ignored in the case of expensive seeds or valuable seeds.

[0006] Further, in the conventional method of sticking a net or bag, it is difficult to germinate and grow because of poor adhesion to the ground and being easily affected by drying, and spraying on a net or the like is required. If it is carried out, there is a problem that germination becomes difficult if the spray thickness is thick.

[0007] The present invention has been made in view of the above-mentioned circumstances, in which the ground and the bag are brought into close contact with each other through the sprayed base, and the seeds are placed in a position suitable for germination and sprayed. Therefore, it is an object of the present invention to provide a greening method that is excellent in germination and growth of woody plants. Another object of the present invention is to provide a greening method that suppresses the drying of the growth base and improves the physical properties of the base to improve the germination and growth of woody plants.

It is another object of the present invention to provide a greening method which eliminates loss due to rebound during spraying of large seeds.

[0009]

Means for Solving the Problems In order to achieve the above-mentioned object, the greening method according to the present invention places an auxiliary material for spray greening consisting of a bag containing an anchor pin and a seed base,
After that, the growth base is created by spraying. Preferably, the bag body is filled with a seed base material in which seeds, an organic substance, a soil improving material, a soil water retaining material, and a germination promoting material are mixed.

That is, in the slope / slope greening work, the auxiliary material for spray greening according to the present invention according to the spray thickness is placed in advance on the designed quantity slope, and then the growth base is sprayed.

[0011]

The bag body in which the seed base material is enclosed is positioned at a required height by the anchor pin, and the subsequent spraying can ensure the spraying in which the seeds are surely arranged at the proper position. In addition, by using an organic base material optimal for germination and growth and a bag containing seeds, stable germination and
Growth can be expected.

Further, it is possible to eliminate the loss caused by the rebound of the used seeds caused by the spraying work.

Further, the density of the plant to be constructed can be adjusted by the number of the auxiliary planting materials for spraying greening placed.

[0014]

EXAMPLE The greening method according to the present invention, after wire-laying construction on the slope, as shown in FIGS. 1 to 4, the auxiliary material (seed bag) 1 or 2 for spraying greening is provided according to the spraying thickness h. After placing on the slope 3, spraying is performed to create a growth base 4 suitable for germination and growth of woody plants. The spray greening auxiliary materials 1 or 2 are obtained by encapsulating a seed base material in which a seed and an organic substance are mixed in a bag body and integrating this with an anchor pin (for the spray greening auxiliary materials 1 and 2, see later). Details). 1 and 3 show a case where the spraying thickness h is thin, and FIGS. 2 and 4 show a case where the spraying thickness h is thick.

The base material used for spraying (spraying base material) is preferably a fertilized organic material as a main material and a cement or a polymer resin as a bonding material (corrosion preventing material), but it does not have erosion resistance. It is possible to use a general base material that can maintain a highly developed growth base for a long time. The spray base material does not need to contain seeds, but a base material containing seeds of herbaceous plants can also be used.

A spray greening auxiliary material 1 or 2 is prepared by enclosing a seed base material, which is a mixture of seeds such as oaks, oysters, oaks, camellias (these seeds are large grains) and organic matter, in a bag body. When 3 to 4 castings were made per 1 m2, and then an organic thick layer base material (spraying base material) was sprayed on 5 to 7 cm,
The germination and growth of the woody plant was extremely good.

FIG. 5 shows a side view of the auxiliary material 1 for greening by spraying according to one embodiment of the present invention. A bag body 13 is fixed to a position above the anchor pin 11 by a stopper 12.

The length l of the anchor pin 11 is 150 to 20.
The scale 14 is about 0 mm, and a scale 14 is attached to the lower portion, which serves as a guide for the depth to be driven when driving on the slope. Further, the anchor pin 11 is preferably made of iron from the viewpoint that the anchor pin 11 is not corroded by the corrosion of the anchor pin 11 after the plant has grown and rooted.

The stopper 12 is a rubber ring. After attaching the bag body 13 to the anchor pin 11, the stopper 12 is inserted into the anchor pin 11 and fixed at a predetermined position on the upper portion, so that the bag body 13 is fixed to the anchor pin 1.
Fixed to 1. Thereby, when the anchor pin 11 is driven up to the scale 14, the bag body 13 is positioned at a predetermined height above the slope. For example, in the case of woody plant seeds, the seedlings are placed at a position about 2 cm above the surface of the sprayed base material, which is the effective cover soil thickness for germination.

The bag body 13 is made of a mesh material that does not inhibit the germination and rooting of plants, and a seed base material in which seeds and organic substances are mixed is enclosed. The bag body 13 has, for example, a volume of 0.5 liter and a size A of about 100 to 200 mm.

FIG. 6 shows a side view of yet another auxiliary material 2 for spray greening according to the present invention. The bag body 23 is fixed to a predetermined position on the upper portion of the anchor pin 21 by the stopper 22, and the driving guide scale 24 is attached to the anchor pin 21. The spray greening auxiliary material 2 is different from the spray greening auxiliary material 1 shown in FIG. 5 in that the central portion of the bag body 23 is fixed to the anchor pin 21.

FIG. 7 is a plan view of the bag body 23. As shown in FIG. 7, an opening 25 for attaching to the anchor pin 21 is provided at the center of the bag body 23. Bag 2
The diameter φ of 3 is about 200 mm. The bag body 23 is not limited to a circular shape, and if the bag body 23 is a quadrangle, it has two sides.
It is about 00 mm.

The seed substrate enclosed in the bag is a mixture of seed, organic matter, soil improving material, soil water retaining material, germination promoting material and the like. Although various seeds can be appropriately used, seeds of woody plants that are large and have severe germination and growth conditions are suitable. The organic matter becomes the germination bed. A mixture of peat moss and bark compost at a ratio of 1: 1 (volume ratio) is used as the main material. A germination bed can also be obtained by adding about 10% (volume ratio) of soil to the organic matter. The soil is preferably cohesive soil such as black soil. The soil improving material is effective in improving air permeability and water retention. Zeolite, perlite, vermiculite, ceramics, etc. are used. The soil water retention material has the effects of improving water retention and preventing the inside of the bag from drying. A high-molecular absorbent polymer or the like is used. The germination promoter has the effect of promoting germination and rooting of seeds. Activated water, gibberellin, etc. are used. In the present invention, in addition to the above, various types can be used according to the germination / growth characteristics of the seeds used.

As described above, since the seed base material does not contain a cement (corrosion preventive material) such as cement, the seeds are given optimum soil conditions for germination and growth in the bag.

Table 1 shows an example of the base material enclosed in the bag.

[0027]

According to the slope greening method of the present invention, the seed base material can be positioned at a required height in the spray base material. Therefore, compared with the exotic herbaceous plant, it is possible to effectively introduce a woody plant whose germination conditions and growth conditions are limited such that the cover soil thickness that can germinate is thin and it does not germinate due to drying of the growth base surface layer. In addition, it is possible to eliminate loss due to rebound when spraying large seeds. Furthermore, when spraying on a thick layer, the amount of seeds used can be greatly saved. This has a great effect on saving the construction cost when the seeds are expensive.
