壊などの公害防止にも役立つ効果を有している。 The present inventor previously issued Patent No. 992813 (Japanese Patent Publication No. 54-
No. 1364), they provided an invention relating to a seed spraying method using flying powder of konjac. the result,
By forming a film on the slope surface layer using pure vegetable konjac powder instead of chemical agents such as asphalt emulsion and urea-formaldehyde resin foam powder used in the conventional slope spraying method,
Not only could it prevent seeds and fibers from being blown away by wind, but it could also be used as a slow-release fertilizer.
Moreover, it has no irritating odor or strange odor, and is effective in preventing pollution such as environmental destruction caused by chemical damage.

成育の歩止まりが悪い。 By the way, in the above-mentioned patented invention, since a slurry is created by stirring and mixing seeds, fertilizer, and fibers with water, the seeds are naturally mixed into the slurry. Therefore, the thickness of the sprayed layer made of the slurry is usually about 1 to 3 mm. on the other hand,
The present inventor also provided a construction method in which soil is added and sprayed to the above-mentioned patented invention.
-43607)). According to this, the thickness of the sprayed layer containing top soil is set in the range of 1 to 10 cm. Therefore, if the sprayed layer is about 1 to 2 cm thick, seeds buried within the layer will germinate normally. However, for example, slopes made of rock fragments cut down during excavation work such as tunnels, and slopes with extremely uneven ground surfaces found in areas cut from hard rock, both have extremely poor soil quality. Therefore, for greening, it is necessary to increase the thickness of the sprayed layer to around 10 cm. In such cases, seeds buried near the surface of the sprayed layer will not have any problem in germination, but seeds buried in the middle or near the bottom of the sprayed layer will be difficult to germinate and will simply dry up. Seeds are often stored away, resulting in a poor yield rate for seed growth.

る。 For the mountain sand of Vegetation Base 2, it is desirable to use high-quality loam soil such as black soil with high organic content, but since the construction site is often located in a mountainous area or other harsh conditions. However, it is difficult to procure large amounts of high quality loam soil. Therefore, we used mountain sand containing pumice, which had been avoided due to its low nutrient content, and made it similar to loam soil, which is effective.

設定しておくものとする。(1) Vegetation base (first step) Mountain sand (including pumice) 17m 3 Flying powder of konjac 255Kg Coating fertilizer (slow-release fertilizer = product name: High Control 180, 700, etc.) 15Kg Water 1500-2000 (2) Greening Net (2nd process) Net body (mesh 1.2cm x 1.2cm) 120m 2 Plant layers (dry grass for feed) 50-100m 3 Paper body (oval with pore diameter 5mm x 3mm, water-soluble adhesive on one side) 120m 2 seeds (Kentatsuki 31-Fuesk, Creeping Red Fescue, etc.) 2Kg anchor (main) 15 anchors (mekushi) 300 Furthermore, the construction procedure of slope greening work according to the present invention will be explained. First, remove floating stones, wood chips, etc. from the slope where construction is to be carried out, and use a well-known mortar spraying machine with pre-measured and stirred mountain sand without mixing with water.
Add konjac powder and coating fertilizer. This is sent to the nozzle by the wind pressure of the compressor, and while adding water at the time of nozzle injection, it is sprayed onto the ground surface 11 through the spray machine and the compressor with the spray nozzle, and the vegetation with the set thickness t is spread in the range of 1.0 to 10 cm. Form the base 2. In this case, when the hardness of the vegetation base 2 is measured using a soil hardness meter (Yamanaka type), if the hardness exceeds 27, the penetration development of seed roots will be poor, and if the hardness is lower than 23, the development of the root system will be poor. However, the sprayed layer does not solidify and flows out, making it impossible to obtain the desired base thickness. Therefore, the soil hardness should be set at around 23 so that the root system can develop well and the base 2 can be properly hardened and fixed by spraying to a predetermined thickness.

る。 And the vegetation base 2 by spraying in the first step.
Once the surface water has receded and solidified, the greening net 7 of the second step is placed between the vegetation base 2 and the net body 3 so that the seeds 6, the plant layer 5, and the paper body 4 are interposed between the vegetation base 2 and the net body 3. At the same time as it is stretched on a base 2, the greening net is pounded with soil so that it comes in close contact with the base, and the edges of adjacent net bodies are overlapped, and anchors 8 are driven into that part and other required places to fix it.

is a slow-acting method in which nutrients are leached out over a long period of about 100 to 700 days by mixing konjac dust and coating fertilizer with easily available water-permeable and breathable mountain sand that does not contain nutrients. A vegetation base 2 with a certain amount is obtained. Konjac powder is used as an adhesive, but since it contains 37.9% nitrogen, 12.5% of it can be used as fertilizer after 30 days at a soil temperature of 25°C. This will further promote the germination and growth of seeds.

る。 The greening net 7 installed on the vegetation base 2 is
A countless number of perforated papers 4 and a plant layer 5 are formed on the inner surface of the net body 3, and seeds 6 are scattered and attached to the inside of the layer and the paper adhesive surface 41, so that when the seeds 6 take root, the plants It invades and develops from layer 5 to the vegetation base 2,
Eventually, it will take root in the ground and take root. Further, since the seeds are protected from direct sunlight and rain and wind by the paper body 4, drying damage such as withering due to drying and other drying damage in the early stage of seed growth can be prevented, and washing away due to scouring can be prevented. Approximately half of the total area of the paper body is occupied by countless small pores 42, so that it can appropriately absorb nutrients from sunlight and prevent bending of germination, and can also prevent germination from starting. The growth rate is at least 3 to 5 days earlier than that of exposed seeds, and the yield of germination and growth is greatly improved.

緑化ネツトとして新規有益である。 Furthermore, since the greening net 7 is attached and fixed to the vegetation base 2, rain and snow do not directly hit the vegetation base 2. Therefore, even if a long period of rainfall occurs in the early stage of construction, the vegetation base 2 will not contain much water and will maintain an appropriate soil hardness, so it will not be difficult to install the base 2 on a steep slope or in a cold climate. Even in places where the ground is prone to freezing, it is possible to prevent the vegetation base 2 from slipping or collapsing, and to stabilize the base 1. However, since the plant layer 5 on the greening net side is hay that has been dried in advance, if water is included after construction, the layer will be 1
After about a month, the rot begins to rot, and this turns into organic fertilizer, which has the effect of promoting seed germination and growth. Moreover, the net body of green net is made of synthetic resin fiber,
In addition, since the presence of the paper body 4 suppresses the lifting and protrusion of the plant layer 5, the mesh is made relatively large to reduce the hindrance to germination, and the material strings are made thicker by the amount of the larger mesh. can improve durability. Furthermore, since the plant layer 5 is made of hay, it is light in weight despite its large volume, and therefore has good workability, and is novel and useful as a slope greening method and a greening net for the method.
