DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation net.

[0002]

2. Description of the Related Art Heretofore, slope greening work (vegetation work) has been performed for the purpose of preventing erosion of a slope. Greening has a relatively strong soil preservation ability and does not choose the time of sowing.
Moreover, as a result of paying attention to characteristics such as fast growing speed, grass was often adopted. However, from the viewpoint of the landscape, it is considered that it is not enough to cover the entire slope with a single species of grass, and recently the introduction of flowers, woody plants, etc. together with pastures seems to be required. It is becoming. The construction of flowers and trees alone is excellent in terms of landscape, but is not sufficient in terms of soil conservation. Therefore, these mixed seeds were considered to be influential and were implemented in various places. However, there were very few cases where desired vegetation was created, and it was found that such mixed seeding was not easy.

The reason for this is that flowers and woody plants and grasses have different physiological and ecological properties, and one of the species is subjected to pressure depending on the construction time or the like. For example, if the construction is carried out in spring or autumn when the growth of grass is vigorous, the grass species will bear on the flowers and woody plants, and conversely in summer when the growth of the flowers and woody plants is strong. These are the ones that underwent pasture species.

[0004]

In view of the above, it is desirable that seeds having different physiological and ecological properties be sown such that they do not compete with each other.
In other words, it is desirable that different vegetation be established and divided. However, the plant growth base that has been generally used in the past has been uniformly finished by mixing grass and woody plants, or grass and flowers. It is extremely difficult to create such a divided state by a method of sowing the seeds uniformly.

Accordingly, an object of the present invention is to provide a vegetation net which can prevent competition between different types of vegetation having different physiological and ecological properties, and can secure an interval for separating and growing them. .

[0006]

In order to achieve the above object, according to the first aspect of the present invention, a first cord having seeds therein is parallel to the first cord at an interval. And the inside includes a first cord-like body and a second cord-like body accommodating a seed to be a competing species, and
The space between the vegetation and the second cord is set such that the vegetation formed between the vegetation and the vegetation can intersect and coexist with each other by interposing an area to be bare. Further, a suppression base material containing a germination / growth suppression material for suppressing germination or growth in the region to be made bare is disposed between the first and second cord-like bodies. It is characterized by the following.

[0007] The invention of claim 2 is the one according to claim 1, characterized in that a fertilizer body is arranged between both cords. In a third aspect of the present invention, in the first aspect, a water impervious sheet is interposed between the cords.

According to the first aspect of the present invention, it is possible to form vegetation due to competing species on land where vegetation has been performed by the first and second cords. The two vegetations themselves are competing with each other so that one can pressurize the other, but the distance between the cords should be large enough that bare land can be interposed between them even when vegetation is formed. Because they are spaced apart, one vegetation does not invade the other,
A good segregation relationship is obtained, and as a result, vegetation in which heterogeneous vegetation coexists is achieved. In addition, since a bare land is interposed between the two vegetation, there is concern about germination and growth of weeds and the like here.
The problem is solved by the growth suppressing base material.

By interposing a fertilizer body as in the second aspect of the invention, it is possible to supply a fertilizer component that is optimal for the physiological and ecological requirements of the species. Further, as in the invention of claim 3, by providing a water-impermeable sheet, germination and growth of buried weed seeds is suppressed, and at the same time, evaporation of soil components is prevented,
Furthermore, the soil temperature is raised or kept warm, which contributes to the germination and growth of the introduced species.

[0010]

The effects of the present invention are as follows. According to the first aspect of the present invention, the cords containing the seeds of different types having different physiological and ecological properties are arranged at intervals such that a bare land will be interposed in the future. The seeds with a high germination and growth rate introduced to prevent the growth of the seeds are prevented from being pressed by the seeds with a slow growth that are introduced for the purpose of scenic landscaping, and a good sorting state is realized.
In addition, since the suppression base material is arranged in a region that is expected to be bare ground, it is possible to avoid the germination and growth of weeds and the like in this region.

According to the second aspect of the present invention, when a fertilizer is provided, it is possible to promote the growth of a slow-growing seed, for example, a seed introduced for the purpose of landscaping. Further, as in the case of the third aspect of the present invention, when the sheet is covered with the water-impermeable sheet, the sheet functions as a mulch, and the growth of vegetation can be further improved.

The above-mentioned net 1 is provided with a required number of cords 2 and 3 each containing a seed of a different type along a direction orthogonal to the inclination direction of the slope.
In this embodiment, the first cord 2 containing woody seeds is used.
And a second cord 3 which is arranged in parallel at an appropriate interval and contains grass seeds. The arrangement interval of the two cords 2 and 3 is such that a bare land 5 having a certain width is formed between a vegetation 3a formed in the future by grass species and a vegetation 2a formed in the future by woody species. The spacing is appropriate.

[0013] The cords 2 and 3 are both enclosed in a rope knitted while mixing a grass species or a woody species, but are pliable and coarsely knitted so as not to inhibit germination. I have. Further, a fertilizer bag 6 containing fertilizer or the like is juxtaposed in the net 1 adjacent to the upper part of the first and second cord-like bodies 2 and 3 (the upper part when constructed on the slope). Fertilization on vegetation is possible. The fertilizer bag 6 is filled with contents such as a slow-acting fertilizer into a long bag material formed in a tube shape, and then partitioned by ultrasonic welding at appropriate intervals, and cut according to the width of the net 1. It was created.

Further, the net 1 of this embodiment is also provided with a suppressing base material 7 containing a herbicide so as to prevent weeds from entering the bare land portion 5. , 3 are arranged in parallel. The herbicide should be selected according to the construction time, etc.For example, in the spring construction, it is effective for broadleaf weeds, and in the fall construction, it is effective for grasses and so on. You. In particular, in order to enhance the scenic effect, a fertilizer component having a high phosphoric acid content is desirable. It is well known that the phosphate component is fixed to clay in soil, and therefore, it is effective to place a high concentration of fertilizer at the elongation site of the plant root system.

As shown in FIG. 3, both the cords 2 and 3, the fertilizer bag 6, and the suppression base material 7 are inserted between the upper and lower filament bundles constituting the longitudinal mesh 1b. The net 1 is mounted on a net knitting machine (not shown), and is knitted and held inside the net 1 during the knitting process of the net 1.

The vegetation net 1 of the present embodiment is constructed as described above.
The net 1 of this example is developed from the upper part to the lower part of the slope, and an anchor pin or the like is driven into place to fix the entire net 1 to the slope. Thereby, both the cords 2, 3 and the fertilizer bag 6 and the suppression base material 7 are respectively arranged in parallel to the direction orthogonal to the slope direction of the slope. In this way, the vegetation work is completed by covering the planned construction area of the slope with the net 1 and covering the soil with an appropriate depth.

The vegetation formed by each net 1 of this embodiment is a vegetation 3a provided by pasture species and a vegetation 2a provided by woody plants. A bare land 5 is interposed between these two vegetation 2a,
Since 3a is not mixed, one vegetation does not press the other regardless of the sowing time. Therefore, different types of vegetation can coexist, and in this case, the soil erosion on the slope is avoided by the root system of the pasture species. The vegetation brought by pasture species and woody plants is not just a sowing plant, but is regularly arranged along the width direction of the slope, so that a good landscape can be obtained. In particular, the vegetation extending along the width direction on the slope of a highway is visually effective.

Although the net 1 of the present invention is constructed as described above, various modifications are possible, and for example, the following modifications are conceivable. In this example, a tree species is set in addition to the grass species. However, the species may be replaced with or added to a flower species. FIG. 5 shows a construction example in which a cord 4 of a flower type is added. In this case, continuous flowering throughout the four seasons can be expected by selecting the species having different flowering times and arranging the cords. The construction target of the net 1 is not limited to the slope, and a flat ground may be selected. In general, it is often pointed out that since the slope is poor, a large amount of base fertilizer and topdressing are liable to be applied, and as a result, the flowers grow and enlarge to inhibit favorable flowering. As a countermeasure for this, it is conceivable to select a growth inhibitor / dwarf agent as the suppression substrate. An impermeable sheet (for example, a vinyl sheet) may be interposed between both cords. The sheet is large enough to cover a certain area between the cords, and is attached to the net by a method such as sewing, bonding, or knitting. Such a sheet regulates the germination of weeds buried in the soil, regulates growth by blocking sunlight, and exerts a mulching effect such as regulation of transpiration of soil moisture and rise in soil temperature. Can promote germination and growth of seeds. In this example, an example using a three-dimensional net is shown. However, in the case of a seed that does not require soil covering, a flat knitted net may be used. The stitch shape of the net is not limited to the square shape as in this example, and a well-known rhombic or honeycomb shape, etc.
There are various types, and the present invention is also applicable to these.
