Description

TECHNICAL FIELD The present invention relates to a vegetation substrate for greening (hereinafter, simply referred to as a vegetation substrate) used in, for example, a slope greening method.

[Prior Art] One of the above-mentioned slope greening methods is a method in which seeds of exotic plants such as grass and seeds of native plants such as flower plants, wildflowers and trees are mixed-sown on the slopes. is there.

However, with this method, the growth power of the grass is strong, and the flower plants, wild grass, and trees are pressed by the grass, and the flower plants, wild grass, and trees that have been sown with great effort cannot be grown, and only the grass is greened. The slope cannot be restored to the mountain.

Therefore, for example, as shown in Japanese Utility Model Publication No. 60-114607, while the grass seeds are housed in a bag made of a water-soluble film together with the fertilizer, flower seeds, wild grass seeds, and tree seeds are provided in the turf grass section. And a flower plant, a wild grass, and a tree are isolate | separated, and the tension grass-like vegetation base material which prevents the pressure on a flower plant, a wild grass, and a tree by pasture is proposed.

[Problems to be Solved by the Invention]

However, in the turf-like vegetation substrate described in the above publication, the bag containing the grass seeds and the fertilizer is made of a water-soluble film, so that the grass seeds and the fertilizer in the bag flow out when there is rainfall. At the same time, in particular, although the grass seeds stagnated in the turf and grew there, and the grass and the flower plant, wild grass, and trees were separated, the grass pressed against the flower plants, wild grass, and trees. There was something that happened.

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 a non-woven fabric, but in this case, the bag is fragile and difficult to tear. However, if the bag is too strong, grass seeds cannot germinate.

The present invention has been made in view of the above matters, and an object thereof is to surely germinate a native species plant such as a flower plant, a wildflower, or a tree without being pressed by an alien species plant such as grass. -To provide a vegetation substrate that can be grown.

[Means for Solving the Problems]

As a result of various investigations by the present inventors, the following means have been reached in order to achieve the above object.

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 stacking the front net and the back net, and the net is provided in the accommodating portion. A vegetation bag containing vegetation seeds is housed in a bag formed by laminating the vegetation seeds and a water-soluble film.

The vegetation substrate according to the second aspect of the present invention comprises a tape-like weft yarn, and a plurality of warp yarns in the transverse direction at appropriate intervals, with a warp yarn interval of 3 to 9 yarns /
Approximately half of the warp yarns of the mesh body woven by entanglement weaving as inches are released from the weft yarns at appropriate intervals in the longitudinal direction, and the weft yarns are weaved in the released warp yarns at the same rate as the weft yarn interval. In addition to forming a double portion, the double portion accommodates a vegetation bag in which vegetative seeds are contained in a bag formed by laminating a net and a water-soluble film.

A vegetation substrate according to a third aspect of the present invention is characterized in that a bag-supporting warp is knitted in a longitudinal direction while including a weft at appropriate intervals between warps of a reticulated body formed by weaving warp and wefts. The bag supporting warp yarns are released from the weaving with the weft yarns at appropriate intervals to form a loop portion capable of communicating in the weft yarn direction, and the bag bearing portions are formed on the surface of the mesh body in the weft yarn direction. A vegetation bag in which vegetation seeds are contained in a bag body formed by laminating a net and a water-soluble film is supported on the part.

[Action]

In any of the above-mentioned inventions, the bag containing the seeds of alien species such as grass and seeds of native species such as flowers, wildflowers and trees is made of a net (made of a poorly soluble material such as polyester). And a water-soluble film are laminated, so that seeds of native plants such as flower plants, wildflowers and trees are stored in this bag together with appropriate fertilizer to form a vegetation bag. When the vegetation base is laid on the slope in a state where the vegetation base is laid on a slope in a state where the vegetation base is housed in a housing formed in a mesh structure having a double structure formed by stacking a front net and a back net, for example, at the beginning of laying, a vegetation bag Since the vegetation seeds inside are covered with a water-soluble film, they do not flow out. Then, for example, when there is rainfall, the water-soluble film 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, it is possible to grow exotic plants and native plant in a well-balanced manner on the slope.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 6 show an embodiment of the first invention. First, in FIGS. 1 to 3, 1 is a vegetation substrate, and a mesh 2 thereof.
Is composed of a front net 3 and a back net 4, and the warp yarns 5 and 6 and the weft yarns 7 and 8 of both nets 3 and 4 are made of polypropylene flat yarn. Then, the front net 3 and the back net 4 are knitted with each other using a Russell machine, leaving a portion which is not knitted in the warp yarns 5 and 6 at an appropriate interval to be formed into a double net structure and knitted. The non-existing portion is formed in the accommodating portion 9.
Further, 10 is a thin cotton made of soot attached to the upper surface of the back net 4, and on the upper surface thereof, together with the fertilizer and the water retention agent 11, for example, vegetative seeds 12 such as flower plants, wild grass or trees 12
Is an adhesive such as polyvinyl alcohol (PVA) 13
It is sprayed and held by the whole surface.

Further, in FIG. 1, 14 and 15 are the accommodating portions 9 respectively.
A fertilizer base bag and a vegetation bag that are appropriately contained and held in the bag. The fertilizer base bag 14 is a bag 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, which is required directly or indirectly for the growth of. And the vegetation bag 15 is the fourth
As shown in the figure, it is made of a material that is difficult to dissolve in water, such as polypropylene, and has a net size of 3 to 5 mm, and does not hinder the germination and growth of vegetation. Alternatively, a starch-based water-soluble (here, so-called semi-water-soluble) film 17 is laminated, and the laminated product is put into a bag 18 formed so that the net 16 faces outside, or ,
It contains vegetation seeds 19 such as flower plant seeds, wild grass seeds, and tree seeds.

The water-soluble film 17 is not limited to the one described above, for example, a water-soluble non-woven fabric or a polypropylene net is used, or semi-water-soluble paper in which about 40% of polypropylene is contained in pulp that gradually dissolves with water, etc. May be used. Further, as grass seeds, there are, for example, a gleeping red fescue, a highland bentgrass, a red top, a bermudagrass, and a Kentucky bluegrass, which may be appropriately selected and stored in the bag 18. And as flower plant seeds, there are yellow daisies, French chrysanthemums, large daisies, chrysanthemums, saw grass, fly trina deco, California poppies, purple hanahana, gypsophila, cosmos, keto, kawaranadeshiko, ginseng, etc. , 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. The water retaining material and some fertilizer may also be stored in each of the vegetation bags 18.

Thus, the vegetation substrate 1 according to the first aspect of the present invention is configured such that the fertilizer base bag 14 and the vegetation bag 15 are properly accommodated in the accommodating portion 9 formed in the mesh body 2. In order to plant the whole plant in a well-balanced manner with exotic plants and native plants, the types of vegetation bags 15 and back nets 4 to be housed in the housing section 9
It is important to properly select the kind of vegetation seeds 12 to be attached and sown in advance on the suhu thin cotton 10 attached to the upper surface of, and to combine them properly.

Therefore, as shown in FIG. 5, in the accommodating portion 9 of the vegetation base 1, the fertilizer-based bag is placed in every other accommodating portion 9a.
14 and a 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, and grass seeds are stored in the storage parts 9b sandwiched between the storage parts 9a. The grass seeds and the flower plant seeds or the tree seeds are housed in a separated state such as housing the housed vegetation bag 15b.

Here, the annual flower plants include California poppy, purple hanahana, gypsophila, cosmos, citrus, and the like, and the perennial flower plants include kawaranadeshiko, ginseng, saw millet, french chrysanthemum, and large ginseng chrysanthemum.

Then, as shown in FIG. 6, the reticulated body 1 having the above structure is
The anchor 20 and the peg 21 are used to stretch the back net 4 so that the back net 4 side is close to the slope 22 and the vegetation bag 15h is located above the fertilizer base bag 14.

In the net body 1 laid on the slope 22, the vegetation seeds 19 in the vegetation bags 15b and 15h are water-soluble film 1 at the beginning of laying.
Because it is covered by 7, it will not leak. Then, for example, when there is rainfall, the water-soluble film 17 is rapidly dissolved by raindrops, so that the vegetation seeds 19 can easily germinate. In this case, since the movement of the vegetation seeds 19 is retained by the net 16 made of a sparingly soluble material, the seedlings germinated from the vegetation seeds 19 can surely grow by receiving the supply of 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 part 9a of the vegetation base 1, although it germinates from flower seeds or tree seeds, it can be grown without being pressed because it is distant from the pasture, and furthermore, in the accommodation part 9a. Since the fertilizer base material bag 14 is provided in, it can grow surely,
The entire slope 22 will 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 has both fertilizer base bag 14 and vegetation bag 15. Alternatively, a double section 25 is formed to accommodate the fertilizer base bag 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, for example, 2000 to 3000. Each tape-shaped flat yarn of about denier is used.

Next, the manufacturing method will be described. The warp 26 and the weft 27 described above are used.
Each of them is woven on a loom, and the weft spacing is 3 to 9 yarns / inch, and a large number of two or more warp yarns 26 are provided every 10 to 100 mm in the transverse direction.
A single net 24 is knitted by plain weaving or entwining weaving. 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. Also weft
As the 27, a wide weft yarn folded a plurality of times to make a narrow width 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 bag 14 can be stabilized.

Next, after knitting in an appropriate length in the longitudinal direction (for example, about 20 to 80 cm), about half of the warp yarns 26 forming the mesh body 24 are released from the weft yarn 27, and the separated warp yarns 26 ′ are combined with the mesh body 24. The same number (3 to 9 threads / inch) of weft yarns 27 'is hammered in and knitted. After providing the part 25 which is divided into the front and the back double, for example, about 3 to 10 cm, it is returned to the single mesh body 24 again. By repeating this, the partial double reticulate body is completed, and the fertilizer base material bag 14 and the vegetation bag 15 are appropriately accommodated in the double portion 25, whereby the vegetation substrate 23 is obtained.

9 and 10 show an embodiment of the third invention of the present application. First, in FIG. 9, 28 is a vegetation base, and the net 29 has both fertilizer base bag 14 and vegetation bag 15. Alternatively, a bag supporting portion 30 for accommodating the fertilizer base material bag 14 is formed.

The structure of the reticulate body 29 will be described with reference to FIG. 10 as well. As the warp yarn 31, a monofilament of about 400 to 500 denier made of polyethylene or polypropylene, for example, and as the weft yarn 32 made of, for example, polyethylene or polypropylene of 2000 to 3000. Each denier flat yarn is used.

Next, a manufacturing method will be described. The above-mentioned warp yarn 31 and weft yarn 32
Are woven on 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 longitudinal direction so as to include the warp 31 between the warp 31 at an appropriate interval in the weft 32 direction, and is released from the weft 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.

Also in the reticulate bodies 24 and 29 according to the second and third inventions, the fertilizer base bag 14 and the vegetation bag 15 are appropriately arranged in the double portion 25 and the bag support portion 30, respectively, and the same as in the first invention. It goes without saying that the effect is obtained.

As can be understood from the above description, the vegetation substrate 1, 2 of the present application
3,28 can accommodate or support the fertilizer base bag 14 and the vegetation bag 15 regardless of whether the reticulate body 2,24,29 has a double structure. The arrangement of the fertilizer base bag 14 and the vegetation bag 15 when laid on the surface 22 is not limited to that shown in FIG. 5, and various arrangements are possible.

That is, FIG. 11 shows an example of the arrangement. In the case of FIG. 11A, the seed 35 of the annual flower plant is removed.
While adhering the seeded thin cotton layer 36 to the mesh body 2,
