SOLUTION: A large number of vegetation base-material housing bags are laid among long-sized ropes, which are arranged on a slope at proper intervals and in which upper tips are fixed, and a material, in which seeds, soil and a fertilizer, etc., are mixed, is force-fed and filled to the whole laid vegetation base-material housing bags. The base-material housing bag consists of a net body, in which the size of one mesh is formed in a square of 2 mm×2 mm and which is made of polyethylene, and the diameter of the knitted yarn of the net body is set in 0.2-0.3 mm at that time.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation base material accommodating bag used for fixing vegetation base material on an inclined ground.

[0002]

2. Description of the Related Art Conventionally, slopes composed of bedrock and gravel soil, slopes of acidic soil, and slopes of cold regions are:
Vegetation was difficult. Therefore, construction of vegetation base materials on these inclined surfaces has been performed by the following method.

[0003] When the slope is rock or gravel soil, a method of digging holes in a pot or groove shape on the slope and installing a base material, filling the bag with soil to form a sandbag, and fixing it to the slope with a pin. There is a method of constructing a vegetation base material by using a mortar beam, a method of installing a vegetation base material in a frame made of paper or plastic plate material, and the like.

[0004] However, these construction methods have the drawback that it takes time and effort to excavate a vegetation on a hard slope, and there is little supply of soil necessary for the growth of plants, so that they cannot be prosperous.

[0005] In addition, when the soil constituting the slope is strongly acidic, the vegetation base material must be installed after the surface of the slope is improved using lime or a soil conditioner.

However, it is difficult to uniformly improve the entire slope by this construction method, and not only does the plant not grow in places where the improvement effect is small, but also soil improving agents such as lime flow out due to rainfall or groundwater. Therefore, there is a disadvantage that the improvement effect is not continued.

[0007] Further, in a cold snowy area, after the vegetation base is constructed, the vegetation base is separated from the inclined surface due to freezing, so that slippage occurs and it is difficult to plant greenery.

[0008]

In order to eliminate such disadvantages of the construction method, the present inventor has already provided an inclined surface with an appropriate interval as disclosed in Japanese Patent Application Laid-Open No. 63-89729. A construction method is provided in which a number of storage bags of vegetation base material are laid between long ropes that are arranged and the upper ends are fixed, and the base material is pressure-filled into all the laid storage bags.

However, in view of the fact that there is no storage bag for reliably germinating turfgrass from the storage bag for the vegetation base material and allowing it to grow well, the present invention provides an optimum vegetation for reliably realizing the construction method. It is an object to provide a base material storage bag.

[0010]

SUMMARY OF THE INVENTION According to the present invention, a large number of vegetation base material storage bags are laid between long ropes which are arranged at an appropriate interval on an inclined surface and whose upper end is fixed, and the laid vegetation base material is laid. In a method for constructing a vegetation base material in which a material in which seeds, soil, fertilizer, and the like are mixed is pumped and filled into all of the storage bags, the base material storage bags are made of polyethylene having a mesh size of 2 mm × 2 mm square. The mesh has a knitting yarn diameter of 0.2 to 0.3 mm.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION By increasing the stem diameter of turfgrass, the nutrients by photosynthesis from the leaves are absorbed by the roots, so that the root growth is improved, and disease resistance, heat resistance, cold resistance and the like are improved. It will be an excellent lawn grass. However, if the mesh of the storage bag is enlarged, the vegetation base material leaks from the mesh when the vegetation base material is press-fitted. Therefore, a test result has revealed that a square having a size of 2 mm × 2 mm is optimal as a mesh satisfying the above conditions.

Further, since the storage bag is not a fabric but a mesh, when the base material is press-fitted in a chiller state, the air in the bag becomes easy to escape, and the base material is pressed into every corner of the bag. Will be able to

The yarn material constituting the mesh is polyethylene, and the yarn diameter is 0.2 to 0.3 mm (0.22 mm is optimal).
Therefore, it is soft and rich in elasticity, can withstand the load at the time of press-fitting, is tough at low temperatures, and promotes good growth without inhibiting the germination of turfgrass with this yarn diameter. I will be. As a result of the test, a strength of 102 kg / cm ² was proved for the base body of the mesh body.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The storage bag for vegetation base material according to the present invention has the following three requirements.

(1) The entire bag is a net formed by knitting with polyethylene fiber yarns, and the size of one net is arbitrary.

(2) The size of one mesh of this mesh is 2 mm
× 2 mm square.

(3) The diameter of the yarn used for knitting the mesh body is
0.2 to 0.3 mm.

Since neither a yarn nor a mesh meeting the above three requirements exists as an off-the-shelf product, a yarn custom-made to a polyethylene yarn manufacturer is supplied to a net manufacturer to be manufactured on a custom-order basis.

The construction method using the above-mentioned vegetation base material storage bag is as follows.

A long rope having an upper end fixed with an anchor is arranged at a predetermined interval on a predetermined slope.

Many vegetation base material storage bags are continuously laid between the ropes thus arranged. Adjacent storage bags are fixed by appropriate means.

Each of these vegetation base material storage bags is perforated, and each bag is filled with a chilled vegetation base material in which seed, soil, fertilizer and the like are mixed by a pressure pump.

[0023]

According to the present invention, ideal construction can be realized by forming the vegetation base material accommodating bag, which is the most important element at the time of construction of the vegetation base material on the slope, as described above. It is.

That is, the stem diameter of the turf to be grown can be increased to promote root growth, and when the base material in a chiller state is press-fitted, the air in the bag is completely extracted to reach every corner of the bag. It can be filled sufficiently and can exhibit toughness that is not affected by changes in temperature.
Due to its flexibility and elasticity, it can sufficiently withstand the load at the time of press-fitting and filling the base material.

As a result, the vegetation base can be fixed for a long period of time without flowing out due to rainfall or freezing and thawing water even on an inclined surface, so that the economic effect is high.
