Description

TECHNICAL FIELD The present invention relates to a vegetative mat for raising seedlings used for protecting slopes, riverbeds, and the like and for making them green.

[Conventional technology]

For example, one of the means for protecting and greening the slope is to install a grid-like frame along the slope and put each soil in a vegetation mat carrying plant seeds or a sandbag bag with stretch grass. There is a means for arranging the sandbags in the section of the grid-shaped method frame, but since the shape of the sandbags is regulated by the sandbag bag, the sandbags are difficult to fit on the uneven surface of the slope and the adhesion is poor. Since the soil stored in one sandbag reaches 20 kg, it is very difficult to work the soil in a high place, and the construction period is long.

Furthermore, fertile soil is required as the soil to be stored in the sandbag, but there is a problem that it is difficult to obtain soil that can meet this requirement and the cost is high.

Alternatively, a wire mesh lath is stretched on the slope, and a vegetation material containing plant seeds is sprayed on the wire mesh lath to simultaneously protect the slope and green, but it is a large scale for spraying the vegetation material. However, there is a problem in that a vegetation material easily flows out by rainwater.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a seedling-raising vegetative mat that exhibits excellent functions in protection of slopes and greening.

[Means for Solving the Problems]

The vegetative mat for raising seedlings according to the first aspect of the present invention, which has achieved the above-mentioned object, is a water-soluble vegetative mat according to the first aspect, wherein at least one of warp yarns and weft yarns at a predetermined interval is made water-soluble and the remaining yarns are made water-insoluble. A plurality of back nets configured to leave a large mesh due to the dissolution of the yarn and a water-insoluble front net having a mesh capable of growing plants are joined at predetermined intervals in the plane direction. The bag part is formed, and the fertilizer lumps are housed in the bag parts at predetermined intervals and the remaining bag parts house seedling-growing vegetation materials, and further, the plants exist in the existing part of the seedling-growing vegetation materials. The feature is that the seeds are carried.

In the vegetative mat for raising seedlings according to the second aspect of the present invention, a water-insoluble first net having a large mesh and a water-soluble second net having a small mesh are polymerized, and the large mesh is formed by dissolving the second net. The first net and the back net and the water-insoluble front net having a mesh capable of growing plants are joined to each other at predetermined intervals in the plane direction to form a plurality of bag portions. To form fertilizer lumps at predetermined intervals in the bag part, and to house seedling vegetation material in the remaining bag parts, and further to carry plant seeds in the existing part of the seedling growing vegetation material. There is a feature in the point.

[Action]

According to the characteristic configurations of the first and second inventions, since the fertilizer mass and the seedling-raising vegetation material are housed in the bag portion of both nets while being protected by the front and back nets, Excellent in transportation and handling.

Moreover, for example, by arranging the seedling-growing vegetation mat on a slope or the like and fixing the net using an anchor or the like, or in the section of the slope frame installed on the slope, etc. By accommodating the mat, construction on the slope of the seedling-growing vegetation mat can be easily achieved, and the fertilizer lump and the seedling-growing vegetation material are stored in the bag part of the net, so that there is no misalignment. Not accompanied.

In the characterizing feature of the first invention, the water-soluble yarns at predetermined intervals are dissolved by water absorption to form a large mesh of the water-insoluble yarns on the back net, or the feature of the second invention. In the configuration, the water-soluble second net is dissolved by water absorption, so that a large mesh of the first net is formed on the back net.

That is, in order to facilitate the transportation and handling of the seedling-growing vegetation mat, and to prevent misalignment between the fertilizer mass and the seedling-growing vegetation material, it is desirable to reduce the mesh size of the front and back nets. Or, even if the seedling-growing vegetation mat is installed on the slope, etc., in order to hold the fertilizer mass and the seedling-growing vegetation material on the slope without displacement, the fertilizer It is preferable to store the lump and the seedling-raising vegetation material in a bag part with a net, but if the mesh size of the back net remains small, the fertilizer lump and the slope of the seedling-raising vegetation material are closely attached. Worsened,
The back net separates the slope from the fertilizer lump or the seedling-growing vegetation material, and rainwater may cause the fertilizer lump and the seedling-growing vegetation material to be misaligned. However, the water-soluble thread or the second net By forming a large mesh on the back net by dissolution, the fertilizer lump and seedling vegetation material adhere well to the surface such as the slope through a large mesh, as a result, suitable for seedling vegetation material Slope protection is achieved.

(To be more specific, in the longitudinal direction of the warp yarns) are joined at predetermined intervals to form a plurality of bag portions 4 and 5 having different sizes in the adjacent ones, and the manure lump 6 is placed in the small bag portion 4 therein. In addition to accommodating, the large bag part 5 accommodates vegetation material 7 for raising seedlings, and
The seedling-growing vegetation material 7 is mixed with plant seeds 8.

As shown in FIG. 2, the back net 2 has a so-called kalami weave net structure in which the mesh d woven by making the pitch of the weft thread c finer than the pitch of the warp thread b is small, and has a virtual line. By making the wefts at a predetermined interval shown by c'made of a water-soluble material and the remaining wefts c and warps b made of a non-water-soluble material, the water-soluble wefts c'become dissolved by absorbing water. , A rectangular mesh e that is as large as possible within the range that can prevent the outflow of fertilizer 9 and vegetation material 11 described later.
Are formed.

On the other hand, the front surface net 3 has a small mesh (a mesh e formed on the back net 2 at the most) that enables plant growth.
It is made of a non-water-soluble material having the same degree of mesh as the above, and is configured so as to prevent outflow of the fertilizer 9 and the vegetation material 11.

The fertilizer lump 6 is a slow-acting or slow-acting fertilizer (for example, solid fertilizer or ivy nitrogen fertilizer is selected as the slow-acting fertilizer, as shown in Japanese Patent Publication No. 1-34570).
For example, a coating fertilizer is selected as a slow-acting fertilizer 9 and is mixed with an inorganic water-retaining material (for example, vermiculite or perlite) or an organic water-retaining material (for example, bark compost or peat moss), and the mixture has a thickness of 0. ．
1-0.6 mm, ventilation rate 10-300 cc / cm ² / sec It is put into the bag 10 made of non-woven fabric, and the functionally slow-acting one is used so that the fertilizing effect can be maintained for a long time. To be

The seedling-raising vegetation material 7 is, for example, organic material such as bark compost or peat moss, inorganic material such as vermiculite or perlite, vegetation material 11 mixed with other soil improving material or general chemical fertilizer, and a water-soluble sheet-shaped member. The vegetation material 11 is wrapped with 12 and retained in a plate shape, and the plant material 8 is mixed with the vegetation material 11.

The seedling-growing vegetation mat 1 thus formed is composed of plant seeds 8
The main component is a vegetation material 7 for raising seedlings and a slow-acting fertilizer mass 14 mixed with each other, which is relatively lightweight as a whole and has a small mesh size similar to the back net 2 having a small mesh size d. Both nets 2, while being protected by the front net 3.
Since the seedling growing vegetation material 7 and the fertilizer lump 14 are contained in the bags 4 and 5 formed by 2, the transportation and handling of the seedling growing vegetation mat 1 are easy.

Then, as shown in FIG. 3, with the surface net 3 facing upward, the seedling-growing vegetation mat 1 is placed on the slope 13 and the anchors 14 and the like are used as appropriate to both nets 2 , 3 to the slope 13 or by placing the seedling-growing vegetation mat 1 in the partition of the grid-shaped slope frame arranged on the slope, the seedling-growing vegetation mat 1 with respect to the slope 13 The installation is easily achieved, and since the fertilizer mass 6 and the seedling-raising vegetation material 7 are housed in the bags 4 and 5 of the nets 2 and 3, there is no displacement.

After that, by waiting for rain or supplying water, the water-soluble weft yarns c ′ at the predetermined intervals are dissolved, so that a large mesh e is formed on the back net 2. In the state where the fertilizer lump 6 and the seedling-growing vegetation material 7 are accommodated in the bags 4 and 5 so that the fertilizer lump 6 and the seedling-growing vegetation material 7 are not misaligned, the fertilizer lump 6 and the seedling-growing vegetation material 7 are closely attached to the slope 13. Can be higher.

On the other hand, the sheet-shaped member 12 enclosing the vegetation material 11 is also dissolved by water absorption, and the restraint by the sheet-shaped member 12 is released, so that the vegetation material 11 is evenly spread as if it was sprinkled on the slope 13. And the slow-acting fertilizer 9 oozes out from the fertilizer mass 6 and the fertile vegetation material 11 containing the slow-acting fertilizer 9 is used as a nursery bed to germinate and grow the plant seeds 8. As a result, protection of the slope 13 and greening are achieved.

Although the large rectangular meshes e are formed on the back net 2 by the water absorption and dissolution of the weft threads c ', the warp threads b at predetermined intervals are dissolved by water absorption or the warp threads at predetermined intervals. It is possible to form a large rectangular (or square) meshing e on the back net 2 by water absorption and dissolution of b and the weft c ′.

As the seedling-growing vegetation material 7, the above-mentioned vegetation material 11 is wrapped in a water-soluble sheet-like member 12 to form a rod shape, or an organic material such as bark compost or peat moss is compressed and held in a plate-like or rod-like shape. It can be changed to a shaped so-called peat board or a peat rod that exhibits water-swelling property, or a peat rod covered with a water-soluble sheet-shaped member.

When the seedling-growing vegetation material 7 is formed in a rod shape as described above, a plurality of the rod-shaped seedling-growing vegetative materials 7 are housed in the large bag portion 5 as shown in FIG. The mat 1 is constructed.

Alternatively, the fertilizer lump 6 may also be rod-shaped, and one or a plurality of the fertilizer lumps 6 may be housed in the pouch portion 4 to form the seedling-growing vegetation mat 1.

Further, as shown in FIG. 5, the fertilizer mass 6 and the seedling-raising vegetation material 7 are formed into rods of approximately the same size, and the size of the bags 4 and 5 formed by the nets 2 and 3 is also the same. A rod-shaped fertilizer lump formed in at least one bag portion 4 which is formed into a substantially same size and is suitable for accommodating the rod-shaped fertilizer lump 6 and the seedling-raising vegetation material 7. 6 is accommodated and the plurality of continuous bag portions 5
It can be carried out by accommodating the rod-shaped vegetation material 7 for raising seedlings.

Next, a typical modified example of the seedling-raising vegetation material 7 will be described with reference to FIG. 6, in which a vertical and horizontal concave portions a are formed by a material obtained by kneading an organic material such as a superabsorbent polymer and a paste material. A shape-retaining member 15 that is dispersed by the formed water absorption is molded, and the above-mentioned vegetation material 11 is housed in each recess a of this shape-retaining member 15, and the recess a is closed by a water-soluble sheet-shaped member 16. For example, the sheet-shaped member 16 is accommodated in the bag portion 5 toward the back net 2 side to form the seedling-raising vegetation mat 1.

According to the above configuration, the shape-retaining member 15 is the vegetation material 7 for raising seedlings.
The shape-preserving member 15 is characterized by being effectively prevented from losing its shape and being excellent in terms of transportation and handling, and the shape-retaining member 15 is dispersed by water absorption to be a vegetation material.

In the example, the plant seeds 8 are mixed in the seedling-growing vegetation material 7, but at least one of the back net 2 and the front net 3, or at least one of the upper and lower surface portions of the seedling-growing vegetation material 7, This sheet-shaped member can be carried out by supporting the plant seeds 8 by means such as adhesion, or by supporting the plant seeds 8 on a sheet-shaped member capable of growing plants regardless of water solubility or water insolubility. Can be carried out by holding at least one of the back net and the front net.

FIG. 7 shows a back net 2 for constructing a seedling-raising vegetation mat 1 according to the second invention.

The back net 2 has a so-called Russell net structure which is produced by shaking a weft yarn from side to side and inserting it into a warp yarn.
It is formed by polymerizing a water-insoluble first net 2a having a large mesh size e and a water-soluble second net 2b having a small mesh size d. Originally, the Russell net is shown by an imaginary line f in FIG. As described above, the weft yarn c is swung left and right at a pitch of about the mesh size between the warp yarns b, and is inserted into the warp yarn b.
In the first net 2a used in the present invention, the swing pitch of the weft yarn c which is swung to the left and right is partially increased to disperse large rectangular meshes e.

The size of the mesh e of the first net 2a is the same as that of the back net 2 according to the first aspect of the present invention in which a large rectangular mesh e is formed by melting the weft threads c '.
It is as large as possible within the range that can prevent the 11 outflows.

Thus, the water-soluble second net 2b absorbs and dissolves in water to leave the non-water-soluble first net 2a, and a large rectangular mesh e formed by the first net 2a is formed on the back net 2. It has become.

That is, the back net 2 used in the seedling-growing vegetation mat 1 according to the first and second inventions is a surface for carrying and handling the seedling-growing vegetation mat 1 until the water-soluble weft thread c'or the second net 2b is dissolved. Although the mesh size d is small, the water-soluble weft thread c'or the second net 2b after the construction of the seedling-raising vegetation mat 1 absorbs water,
It is characterized in that large rectangular meshes e are dispersedly formed on the back net 2.

Although the water-soluble weft thread c'or the second net 2b is melted to form a large rectangular mesh e on the back net 2, a large square mesh e is formed. It goes without saying that it can be configured and implemented as described above.

〔The invention's effect〕

As described above, according to the seedling-growing vegetation mats of the first and second inventions, the fertilizer lump and the seedling-growing vegetation material are protected by the front and back nets, and the fertilizer lump and the seedling-growing vegetation material are net bags. In addition to being housed in the section, the mesh of the back net is fine until a large mesh is formed by water absorption and dissolution, so that the vegetative mat for raising seedlings can be excellent in transportation and handling.

Moreover, for example, by arranging the seedling-growing vegetation mat on a slope or the like and fixing the net using an anchor or the like, or in the section of the slope frame installed on the slope, etc. By accommodating the mat, construction on the slope of the seedling-growing vegetation mat can be easily achieved, and the fertilizer lump and the seedling-growing vegetation material are stored in the bag part of the net, so that there is no misalignment. Not accompanied.

Then, a large mesh is formed on the back net by water-absorption dissolution of the water-soluble thread or the second net at the predetermined intervals, and thus the adhesion between the fertilizer lump and the seedling-growing vegetation material on the slope is increased. However, since the fertilizer lump and the planting material for raising seedlings are still contained in the bag part of the net,
Spilling and misalignment of fertilizer lumps and seedling vegetation materials due to rainwater are effectively suppressed, and the planting of seed vegetation materials as seedbeds allows germination and growth of plant seeds to achieve greening on slopes, etc. As a whole, it is possible to provide a vegetative mat for raising seedlings, which is lightweight, has excellent workability, and is suitable for greening, and can be produced in a factory and can stabilize quality at low cost.
