Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation base for greening (hereinafter, simply referred to as a vegetation base) used in a greening method.

[0002]

2. Description of the Related Art As one of the above-mentioned slope greening methods, there is a method of sowing seeds of exotic plants such as grass and seeds of local plants such as flower plants, wildflowers and trees on the slopes. .

However, with this method, the growth power of the grass is strong, and the flowers, wild grass, and trees are pressed by the grass, and only the grass is vegetated while the flower plants, grass, and trees that have been mixed-sown cannot grow, and the landscape is reduced. Inferior in terms of quality, and the slope, which is the final goal, cannot be restored to the mountain.

Therefore, for example, the actual utility model number 60-114607.
As shown in the publication, while the grass seeds are stored together with the fertilizer in a bag made of water-soluble paper or water-soluble film,
Flower plant seeds, wild grass seeds, and tree seeds are provided in the Zhang turf part, and the grass and the flower plant, wild grass, and trees are separated to prevent the grass from pressing on the flower plants, wild grass, and trees. Proposed.

[0005]

However, in the stretched grass-like vegetation substrate described in the above publication, since the bag containing the grass seeds and the fertilizer is made of water-soluble paper or water-soluble film, there is rainfall. And the grass seeds and fertilizer in the bag will be washed away, and especially the grass seeds will stagnate in the stretched grass part and grow there, and the grass seeds,
Despite the separation of flower plants, wild plants and trees, pastures sometimes pressed flower plants, wild plants and trees.

On the other hand, as an improvement of the technique described in the above publication, it is conceivable to store grass seeds and fertilizer in a bag made of non-woven fabric. In such a case, the bag is fragile and fragile. There is a problem in that the grass seeds cannot germinate if the bag is too strong.

The present invention has been made in view of the above matters, and its object is to provide native species plants such as flower plants, wildflowers and trees without being pressed by alien species plants such as grass. It is to provide a vegetation substrate that can be surely germinated and grown.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the inventors of the present invention have made various investigations and have reached the following means.

That is, in the vegetation substrate according to the first aspect of the present invention, the accommodating portion is formed in the weft direction between the both nets of the double-structured net formed by superposing the front net and the back net, and In addition, a vegetation bag containing vegetation seeds is housed in a bag formed by laminating a net and semi-water-soluble paper.

The vegetation substrate according to the second aspect of the present invention is a net-like body formed by weaving tape-like wefts in a entangled weave with a number of warps in the transverse direction at appropriate intervals with a warp interval of 3 to 9 yarns / inch. About half of the warp yarns are released from the weft yarn at appropriate intervals in the longitudinal direction, and the weft yarns are weaved on the released warp yarns at the same rate as the weft yarn interval to partially form a double portion. In addition, a vegetation bag containing vegetation seeds is housed in a bag formed by laminating a net and semi-water-soluble paper.

In the vegetation substrate according to the third aspect of the invention, the bag-supporting warp yarns are knitted in the longitudinal direction while including the weft yarns at appropriate intervals between the warp yarns of the reticulated body formed by weaving the warp yarns. At appropriate intervals in the longitudinal direction, the bag-supporting warp yarns are released from weaving with the weft yarns to form loop portions that can communicate in the weft yarn direction, and the bag body bearing portions are formed in the weft yarn direction on the surface of the mesh body. A vegetation bag in which vegetation seeds are contained in a bag formed by laminating a net and semi-water-soluble paper is supported on the bag support portion.

[0012]

In any of the above-mentioned inventions, the bag containing the seeds of the exotic plants such as grass and the seeds of the flower plants, and the native plants such as wild grass and trees is made of a net (such as vinylon) which is hardly soluble. It is made by laminating a semi-water-soluble paper (paper containing polypropylene) and a semi-water-soluble paper (made of a material and a soluble material such as soup), so that, for example, flower plant seeds, wild grass, trees The seeds of native species such as plants are stored together with appropriate fertilizer to form a vegetation bag.
For example, when the vegetation substrate is laid on the slope in a state where the vegetation substrate is laid on the slope in a state where the vegetation substrate is housed in a housing formed in a double-structured net formed by stacking a front net and a back net, at the beginning of laying, Since vegetation seeds are covered with semi-water-soluble paper, they never flow out.

Then, for example, when there is rainfall, the semi-water-soluble paper is rapidly dissolved by raindrops, so that the vegetation seeds can easily germinate. In this case, since the movement of the vegetation seeds is retained by the net made of the sparingly soluble material, the seedlings germinated from the vegetation seeds can surely grow by receiving the fertilizer and the water. Then, by appropriately changing the type of vegetation seeds contained in the bag, each of the exotic plants, flower plants, and native plant can be grown on the slope in a well-balanced manner.

[0014]

The entire surface is sprayed and held by an adhesive 13 such as VA).

Further, in FIG. 1, 14 and 15 are a fertilizer base bag and a vegetation bag, which are appropriately contained and held in the accommodating portion.

The fertilizer base bag 14 is made of a corrosion-resistant and insoluble non-woven fabric having a thickness and air permeability such that fertilizer nutrients gradually exude due to rainfall or the like. It contains a fertilizer base material, such as an agent, which is directly or indirectly necessary for plant growth. As shown in FIG. 4, the vegetation bag 15 is made of a material such as vinylon, which is difficult to dissolve in water, as a warp, and a staple which is eventually dissolved in water as a weft, and has a mesh of 3 to 5 mm. Net 16 and a semi-water-soluble paper 17 containing about 40% of polypropylene in a pulp that does not hinder the germination and growth of vegetation and is gradually dissolved by moisture, and the laminated A bag 18 formed so that 16 is on the outer side contains grass seeds or vegetation seeds 19 such as flower plant seeds, wild grass seeds, and tree seeds.

Examples of grass seeds include creeping red fescue, highland bentgrass, red top, bermudagrass, entucky bluegrass, etc. These may be appropriately selected and stored in the bag 18. And as flower plant seeds, there are yellow daisies, French chrysanthemums, dairy chicken chrysanthemums, saw grass, fly trina deco, California poppy, purple hanahana, gypsophila, cosmos, keito, kawaranadeshiko, ginseng, and wild grass seeds are wormwood. , silver grass, Medohagi, include Japanese knotweed, further, the tree seeds, pine, Alnus firma, strip weasel, Yamahagi, include top tether, if accommodated by selecting them appropriately into the bag 18 Good. A water retention agent and some fertilizer may be stored in each of the vegetation bags 18.

Then, the vegetation substrate 1 according to the first aspect of the present invention.
Is a fertilizer-based bag inside the accommodating portion 9 formed in the mesh body 2.
14 and vegetation bags 15 are properly accommodated, but in order to green the entire slope in a well-balanced manner with exotic plants, flower plants and native plants, the vegetation bags 15 to be accommodated in the accommodating section 9 Type and Sufu thin cotton affixed to the bottom of the back net 3
It is important to properly select the types of vegetation seeds 12 to be adhered and sown in advance to 10, and to combine them properly.

Therefore, as shown in FIG. 5, the vegetation substrate 1
In the accommodating part 9 in, the fertilizer base bag 14 and the vegetation bag 15h in which flower plant seeds such as annual flower plant seeds and perennial flower plant seeds and tree seeds are appropriately mixed are provided in every other accommodating part 9a. , And the vegetation bag 15b containing the grass seeds is housed in the housing 9b sandwiched between the housings 9a in a state where the grass seeds and the flower plant seeds are separated. .

Here, the annual flower plants include California poppy, purple hanahana, gypsophila, cosmos, caeto, and the like, and the perennial flower plants include kawaranadeshiko, ginseng, yarrow, French chrysanthemum, and large brocade.

As shown in FIG. 6, the reticulated body 1 having the above-mentioned structure is provided with anchors 20 and pegs 21 so that the back net 4 side is close to the slope 22 and the vegetation bag.
It is stretched so that 15h is located above the fertilizer base material bag 14.

In the reticulated body 1 laid on the slope 22, the vegetation seeds 19 in the vegetation bags 15b and 15h are covered with the semi-water-soluble paper 17 at the beginning of laying, and therefore do not flow out. Then, for example, when there is rainfall, the semi-water-soluble paper 17 is gradually dissolved by raindrops, so that the vegetation seeds 19 can easily germinate. In this case, the movement of the vegetation seeds 19 is retained by the net 16 made of a sparingly soluble material.
The seedlings germinated from 19 can be reliably grown by receiving fertilizer and water.

Then, in the vegetation base 1, the grass in the vegetation bag 15b housed in the housing portion 9b grows quickly and grows in a streak shape to protect the slope 22. In the other accommodation section 9a of the vegetation substrate 1, flower plants, wild grass, and tree seeds germinate, but since they are distant from pasture grass, they can grow without being pressed by them, and moreover, the accommodation section
Since the fertilizer base material bag 14 is provided in the 9a, the fertilizer base material bag 14 can surely grow and the entire slope 22 can be greened in a well-balanced manner.

FIGS. 7 and 8 show an embodiment of the second invention of the present application. First, in FIG. 7, 23 is a vegetation base, and the net 24 is a fertilizer base bag 14 and a vegetation bag. A double section 25 is formed to accommodate both of the 15 or fertilizer based bags 14. The structure of the mesh 24 will be described with reference to FIG. 8. The warp 26 is made of polyethylene or polypropylene having a monofilament of about 400 to 500 denier, and the weft 27 is made of polyethylene or polypropylene of 200 to 3000. Each tape-shaped flat yarn of about denier is used.

Next, the manufacturing method will be explained.
The weft yarns 27 and the weft yarns 27 are respectively laid on a loom, and a single net-like body 24 is knitted by plain weaving or entanglement weaving with a large number of two or more warp yarns 26 every 10 to 100 mm in the transverse direction at a weft yarn spacing of 3 to 9 yarns / inch. In this case, if the width of the weft yarn 27 is large, the number of shots per inch may be reduced, and if it is small, it may be increased. Further, as the weft yarn 27, a wide weft yarn folded a plurality of times to be narrowed may be used. Then, by setting the shading rate of the mesh body 24 at the time of knitting to about 50%, the moisture state in the fertilizer base material bag can be stabilized.

Next, an appropriate length in the vertical direction (for example, 20 to 80 cm)
About half of the warp yarns 26 forming the reticulate body 24 are released from the weft yarns 27, and the released warp yarns 26 ′ have the same number as the reticulate body 24 (3 to 9 yarns / inch). Type in and knit. After the part 25 for separating the front and back sides is provided, for example, about 3 to 10 cm, it is returned to the single mesh body 24 again. By repeating this, the partial double mesh body is completed, and the fertilizer base bag 14 and the vegetation bag 15 are appropriately accommodated in the double portion 25, whereby the vegetation substrate 23 is obtained.

FIGS. 9 and 10 show an embodiment of the third invention of the present application. First, in FIG. 9, 28 is a vegetation base, and its net 29 is a fertilizer base bag 14 and a vegetation bag. A bag support portion 30 for accommodating both 15 or the fertilizer base bag 14 is formed.

The structure of the reticulate body 29 will be described with reference to FIG. 10 as well. The warp yarns 31 are monofilaments of about 400 to 500 denier made of polyethylene or polypropylene, and the weft yarns 32 are made of polyethylene or polypropylene. Flat yarns of about 2000 to 3000 denier are used.

Next, the manufacturing method will be explained.
The weft yarn 32 and the weft yarn 32 are respectively applied to a loom, and the single net-like body 29 is knitted by plain weaving or entanglement weaving. Then, when the above-mentioned knitting is performed, the bag supporting portion warp 33 is knitted in the warp direction between the warp yarns 31 at an appropriate interval so as to include the weft yarns 32, and is separated from the weft yarns 32 at each longitudinal interval. Thus, the loop portion 34 capable of communicating in the direction of the weft yarn 32 is formed on the surface of the mesh body 29, and the bag support portion 30 is formed between the loop portion 32 and the mesh body 29.

The reticulate body according to the second and third inventions
Also in 24 and 29, its double part 25 and bag support
It goes without saying that the fertilizer base bag 14 and the vegetation bag 15 are appropriately arranged in the respective 30 to achieve the same effects as the first invention.

As can be understood from the above description, the vegetation bases 1, 23, 28 of the present application have the fertilizer base bag 14, the vegetation bag 15 regardless of whether the mesh bodies 2, 24, 29 have a double structure. Vegetation substrate 1, 23, 28
The arrangement of the fertilizer base material bag 14 and the vegetation bag 15 when laying on the slope 22 is not limited to that shown in FIG. 5, but various arrangements are conceivable.

That is, FIG. 11 shows an example of the arrangement. In the example shown in FIG. 11 (A), the seed 35 of the annual flower plant is used.
While affixing the thin cotton layer 36 sprayed and sown on the reticulate body 2, the fertilizer base bag 14 and the vegetation bag 15h containing the seeds of the perennial flower plant are housed and housed in the housing part 9a. The vegetation substrate 1 containing a vegetation bag 15b containing grass seeds in the portion 9b is laid so that the layer 36 is close to the slope 22.

Further, in the one shown in FIG. 3B, a thin cotton layer 38, in which seeds 37 of an annual flower plant and a perennial flower plant are sprayed and sown, is attached to the reticulate body 2, while in the accommodating portion 9a. The fertilizer base bag 14 and the vegetation bag 15b containing the grass seeds are housed in the container, and the fertilizer base bag 14 is housed in the housing portion 9a. It is laid so that it is close to.

In FIG. 11, the mesh body 24 according to the second invention or the mesh body 29 according to the third invention is used as the mesh body.
Needless to say, may be used.

[0038]

Since the present invention is constructed as described above,
According to the reticulate body of the present invention, it is possible to reliably retain vegetative seeds such as seeds of exotic plants such as grass and flowers and wild plants, seeds of native plants such as trees without causing migration or runoff. At the same time, it is possible to smoothly germinate and grow them. In particular, when the seeds of exotic plants such as grass and the seeds of native plants such as flower plants, wildflowers and trees are arranged separately, the flowers of exotic plants such as pasture are not pressed. Local plants such as plants, wild plants and trees can be germinated and grown without fail, and the slopes can be planted in a desired state. Needless to say, the vegetation substrate according to the present invention can be applied to other than greening of slopes.
