Description

[Detailed Description of the Invention] The present invention relates to an improvement of a conventional vegetation bag, and more specifically, to an improvement of a soil bag for vegetation.

Recently, soil bags for vegetation have been used in large quantities to carry out greening within the field-cast lattice frames on road slopes. Most of the slopes on which this type of in-situ casting is performed are bedrock slopes, and therefore, vegetation grows only on the nutrients in the soil and other vegetation materials filled in the vegetation bags. After 2 to 3 years, they start to decline due to lack of nutrients (lack of fertilizer).

As a method to prevent this decline, a method of attaching bag pieces containing slow-release fertilizer to vegetation bags was proposed in 1983.
Proposed by No. 9525.

However, when simply attaching bag pieces to vegetation bags or sandbag bags, one piece of the vegetation bag sag, making it extremely difficult to add soil or other vegetation materials, and at the same time making it difficult to fill the slow-release fertilizer. The position of the bag pieces is not constant in the vegetation bag, and if they are located close to the upper plant seeds, the seeds will cause fertilizer damage and at the same time, the fertilizer will decompose faster.
Fertilizer runs out after about six months, making it impossible to achieve the initial goal.

In addition, slow-release fertilizer means that it dissolves within about 6 months after application.
Since it decomposes, it can be said that it is meaningless if you expect it to have a fertilizing effect during the decline period 2 to 3 years after construction.

Further, as described above, if the bag pieces are simply attached to the vegetation bag, the bag pieces may not be pulled or pulled when soil or the like is put in, and the attached portions may be crushed.

The present invention was devised in view of the shortcomings of the conventional improved vegetation bag, which is simply a bag piece filled with slow-release fertilizer attached to the above-mentioned vegetation bag. The present invention was arrived at because it is possible to improve the drawbacks of the vegetation bag to which the above-mentioned bag pieces are attached by making the bag have a double structure.

That is, in the present invention, a part of the net fabric constituting the vegetation bag is made double-faced with several warp threads, and the pocket-shaped part is formed by weaving and weaving the warp threads with the weft threads alternately intertwined with the front and back sides. This is a vegetation bag in which a bag filled with vegetation material is housed in the housing part.

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

First, to explain the material constituting the vegetation bag of the present invention, any piece of cloth may be used, regardless of whether it is chemical or vegetable, as long as it has a texture that allows plants to germinate. A knitted fabric formed by knitting a chemical tape such as polyethylene or polypropylene is most suitable for use.

As shown in Figure 1, the first method of making a part of the net fabric double-layered is to make 5 to 6 warp threads double on the front and back sides of a part of the net fabric, and then add the weft threads to this. Twist the front and back sides alternately and knit.

In order to form a bag using the mesh fabric 1 made as described above, first, the opening is made by folding a part of the fabric so that the string 3 can pass through, and then the opening is used as a passage for the string. , As shown in Figure 3, the bag is folded so that the double-layered pocket-like accommodating part is located almost in the middle of the bag, and the two sides excluding the opening are sewn together to form a vegetation bag. The most common manufacturing method is to heat cut the inner upper portion of the section to provide a complete container for the vegetation material.

Further, it is possible to attach a grass strip 4 to one or both opposing surfaces of the pocket-shaped storage portion on the inner surface of the vegetation bag of the present invention, or to attach seeds and fertilizers using a water-soluble glue. is normal.

If this vegetation substrate is not attached in advance,
Vegetation bags are filled with soil and other vegetation materials, stacked or pasted, and then greened by spraying seeds.

The vegetation material 2 accommodated in the double-structured pocket-shaped storage part of the above-mentioned vegetation bag has a fertilizing effect of 2.
It is one or more types of ultra-slow-release high-control fertilizer (trade name), ordinary chemical fertilizer, water-retaining material, and soil improvement material, and is filled into a cylindrical bag made of non-woven fabric, paper, or cloth. It is then stored in the storage section.

Furthermore, there are cases where the storage section is simply filled with solid fertilizer.

As described above, the present invention has a pocket-like part formed by weaving and weaving a part of the net fabric constituting the vegetation bag by making it double-sided with several warp threads, and intertwining the warp threads with the weft threads alternately on the front and back sides. Since this is a vegetation bag in which the storage part is a storage part and a bag filled with vegetation material is stored in the storage part, the vegetation material can be stored very easily.

Therefore, compared to the conventional method in which bag pieces are simply attached to the vegetation bag body, it is easier to fill one piece of the bag body with vegetation materials such as soil without causing any sag.
Because the part where the fertilizer and other vegetation materials are always located is always the same, it is possible to maintain the decomposition of the fertilizer at a constant level, and the attached part will not be crushed due to the bag pieces being pulled when adding soil, etc. It's gone.

Furthermore, if you use an ultra-slow-release fertilizer that takes effect about two years after application, unlike conventional fertilizers, the fertilizer will completely decompose after two to three years during the decline period. Unlike other fertilizers, the fertilizer decomposes rapidly during the decline period, so it can be expected to be very effective.
