Description

[Detailed Description of the Invention] The present invention is capable of restoring declining vegetation to its original green state over a long period of time on a slope where greening work such as seed spraying has been carried out;
Maintenance is required from the beginning of construction2.
This invention relates to a vegetation implement having two characteristics.

Slopes that have been cut out are usually in poor condition, and there are also many acidic soils, so if greening works such as seed spraying are carried out on these soils, the supply of nutrients from the soil will be insufficient. This is possible, and growth is steady for two to three years due to the effects of fertilizers, soil conditioners, etc. brought in at the time of construction, but after four to five years, a decline in vegetation is observed. It's coming. For this reason, on rare occasions, attempts have been made to spray fertilizers, soil conditioners, etc. as part of maintenance, but the effects are very short-lived and are currently not as effective as expected.

This is because fertilizers and soil conditioners are sprayed in liquid form, so when it rains, the fertilizer or soil conditioner washes away, and liquid fertilizers do not have slow-release fertilizers. .

In addition, these methods require large machines to spray, and have the disadvantage that they cannot be carried out at sites where machines cannot be brought in.

Therefore, there has been a desire for a simple construction method that can be expected to have long-term fertilizer effects and soil improvement effects.

On the other hand, there has also been a desire for a method that avoids the above-mentioned maintenance from the beginning of construction, that is, a method that can maintain the fertilizer effect or soil improvement effect over a long period of time from the beginning of construction.

The present invention aims to restore the above-mentioned degraded slope to its original greenery and to provide a vegetation device that does not require maintenance from the beginning of construction.

The configuration of the present invention will be explained in detail below based on the drawings.

First, the elongated bag 1 used in the present invention is made of nonwoven fabric,
It is made by sewing together materials such as paper and cloth, and usually uses nonwoven fabric with an air permeability of 10 to 300 c.c./cm/sec and a thickness of 0.1 to 3 mm.

If this long and narrow bag is filled with a mixture of slow-release fertilizer such as resin coating, slow-release fertilizer such as ivy nitrogen, and quick-release general compound fertilizer, it will last for a long time from the beginning of construction. It has the effect of evenly applying fertilizer.

In addition, by filling not only fertilizer but also water retaining materials such as clay minerals, vermiculite, perlite, and organic fibrous materials at the same time, the fertilizer effect can last for a longer period of time.

Bags containing soil conditioners are usually filled with charcoal and slaked lime to correct acidity.

Further, the water-retaining bag is made by filling the above-mentioned vermiculite, perlite, and organic fibrous material alone.

A long and narrow bag 1 filled with various materials in this way
are selected as appropriate and attached to the connector.

The connecting body is one in which cylindrical portions 3 are provided at appropriate intervals of the belt-shaped double net 2. In order to construct the vegetation device of the present invention using this band-like net, cylindrical parts 3 are provided at appropriate intervals in the longitudinal direction of the band-like net, and a plurality of cylindrical parts are arranged in parallel in the longitudinal direction as appropriate, using the cylindrical parts as connecting parts. On the other hand, a plurality of elongated bags filled with the base material described above are placed horizontally in parallel vertically at appropriate intervals, and inserted into the cylindrical part of the belt-shaped double net. Thus, the intersecting portions of the connecting bodies are integrated into a coarse net-like structure.

The vegetation device of the present invention can be completed in the manner described above, but since the elongated bag can be filled with various materials as described above, it can be filled with various materials depending on the site, for example, even if it is a poor land. For dry areas, use a water retention bag; for acidic areas, use a soil improvement bag.
They can be selected and used as appropriate, and can also be used in various combinations.

The vegetation implement of the present invention is packaged in a roll form, which is dropped from the top of the slope and stretched using anchor pins 4 or the like.

As described above, in the present invention, a plurality of belt-shaped double nets each having cylindrical portions provided at appropriate intervals are installed in parallel in the vertical direction at appropriate intervals, and on the other hand, an elongated bag body is installed horizontally at appropriate intervals. This is a vegetation device in which a plurality of nets are installed vertically in parallel at appropriate intervals, and the net is constructed by integrating the intersection of the cylindrical part of the belt-shaped double net and the elongated bag body. Since the net is a belt-shaped double net with a cylindrical part, the vegetation tool can be constructed using an extremely simple method of simply inserting an elongated bag into the cylindrical part of the belt-shaped double net and integrating the intersecting parts. In addition, the net-like appearance of the planting device is very coarse, so even if it is stretched over an area where vegetation grows, the planting device will not be lifted up by the vegetation, and it is legal. It can be stretched to fit the surface.

In addition, if the planting device of the present invention is used as a fertilizer supply material or soil improvement material from the beginning of construction rather than as maintenance, it is possible to not only supply nutrients for various materials but also to When the seeds are sprayed, the elongated bag acts as a retainer for the sprayed material, and the seed-sprayed substrate does not wash away.

Furthermore, if a net-like body is stretched on top of the vegetation device, and a thick layer of vegetation base material is sprayed on top of the net-like body, the net-like body will be suspended above the slope by the vegetation device. Therefore, the net-like body is located in the middle layer of the vegetation base material, and has the effect of preventing washing away. In this way, if the vegetation device of the present invention is placed on a slope where vegetation is declining, it can have a fertilizer effect, a soil improvement effect, and a water retention effect depending on the situation of the slope, and can restore the original greenery. be.

Furthermore, since it is easy to construct and has a very long-term effect, it can be applied to various vegetation construction methods so that not only maintenance but also maintenance is not required from the beginning of construction.
