DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation mat used for greening slopes and slopes, and more particularly to a mat for vegetating wild grass.

[0002]

2. Description of the Related Art Various methods have been known for greening slopes and slopes. However, the present invention is directed to a mat that supports seeds and fertilizer. The present invention relates to a vegetation mat method for laying a vegetation base in the form of a slope on a slope or the like, and to a vegetation mat used in the vegetation mat method.

[0003] Vegetation mats may cause environmental destruction or hinder the animals' survival by hindering the survival of the animals. Therefore, vegetation mats having less permanent residues have been proposed. Specifically, Japanese Patent No. 2525496 discloses a vegetation mat in which a seed and a fertilizer are interposed between a floc of a starch-based compound, and the surface is covered with a net formed of a material that can be decomposed by microorganisms in the soil. Is disclosed. Also, Japanese Patent No. 2594227 discloses that seeds are scattered on a vegetation base material such as bark compost or peat moss,
There is disclosed a vegetation mat in which the upper and lower surfaces are covered with a water-soluble sheet, and the surface is further covered with a water-disintegrable film (a film that gradually decomposes with water) and covered with a net.

However, in the above-mentioned conventional vegetation mat,
A vegetation mat using a material that decomposes naturally has been proposed, but adopting a special member called a flocculent body using a starch-based compound as a vegetation base leads to an increase in vegetation construction costs and When the surface of the base material is coated with a water-disintegrable film, the water-disintegrable film absorbs the rainwater and evaporates it as it is in a light rain area or when the planting board is dry. Can not. Further, the vegetation mat formed of the above-mentioned naturally decomposed material, for example, produces a flocculent body of a vegetation base material, or attaches a water-soluble film that is easily damaged on the front and back of the vegetation base material, all of which are special. It requires complicated processing, and its manufacture and handling are complicated.

[0005] When wild grass is used as a vegetation plant, environmental conditions (weather conditions) for satisfying the germination condition of the turf are required, and weed management before germination is required. A desired lawn cannot be obtained only by seeding. Therefore, in general, a so-called upholstery, which cuts a turf cultivated by a turf grower into a predetermined size and spreads the turf on a lawn vegetation site, is often used. Of course, after the cut turf (turf), the roots of an appropriate depth remain, so that the lawn naturally grows in the cut portion, so that the demand for the turf can be satisfied by changing the cut portion.

However, lawn vegetation with the above-mentioned upholstery is
It requires turf stripping work, transportation, maintenance of planting spots, and planting work, which are not necessarily efficient vegetation works. Therefore, in recent years, a lawn spraying method has been proposed as a labor-saving means for lawn vegetation work. This is a combination of wild turf seed that has been subjected to germination promotion treatment, fertilizer (advanced chemical fertilizer), curing material (fiber), stabilizer (acrylic resin, vinyl acetate resin), soil improver (magnesium lime: soil PH value). Turf vegetation by spraying on flat or sloped surfaces.

The germination condition of wild grass itself is that the accumulated temperature is 300
It germinates after a high temperature state continues for a considerable period of time at about -400 ° C. For this reason, the germination rate is poor in cold places such as northern Japan. In particular, even if spraying is performed using seeds that have been subjected to germination promotion treatment, some of them may not germinate and become sparse vegetation. Work is needed. If a low temperature is expected, germination is difficult because it is difficult to germinate. Therefore, it is necessary to cover with a film and maintain the heat, and if it takes time to germinate, weeds will proliferate faster.

Accordingly, the present invention proposes a vegetation mat which can be surely greened by wild turf even if there is no risk of environmental pollution and the vegetation base is insufficient.

[0009]

A vegetation mat according to the present invention comprises, on a base portion, a vegetation portion layer in which a fertilizer and wild turf seeds just before germination are mixed in a base material, and flying seed cultivation is provided on the upper surface thereof. The present invention is characterized in that a blocking layer is laminated and the whole is sewn and integrated.

Therefore, when the vegetation mat is laid on a vegetation target place such as bare ground and fixed with an appropriate pile, a vegetation layer of a base material containing seeds and fertilizer is formed by the base and the palm fiber layer. Since the upper and lower surfaces are blocked by the flying seed breeding inhibition layer, it is installed properly in close contact with the ground of the vegetation without spilling out, and the seeds of wild grass are in the state just before germination,
It germinates immediately and can pass through the seed-growth-inhibiting layer, revealing its surface, and even if the vegetation base of the ground is insufficient, the mat itself has a base material, Greening by difficult wild grass is easily realized, and all materials naturally become the ground of the laid surface due to aging.

[0011]

Next, an embodiment of the present invention will be described. The vegetation mat shown in the embodiment is obtained by laminating a base portion 1, a vegetation portion layer 2, and a flying seed breeding prevention layer 3, and suturing the whole with a natural fiber thread 4, and the entire size is 1 × 5 m.
It is formed to a size of the order.

The base is made of Japanese paper 11 having appropriate strength.
Is sufficient, but a jute cloth 12 may be laid below the Japanese paper 11 as needed.

The vegetation layer 2 is provided on a base material 21 such as bark compost, peat moss, humus, or the like, on a base material 21 just before germination.
A mixture of 2 and fertilizer 23, using an amount of about 15 liters / square meter.

As a first means, the vegetation section layer 2 is produced by immersing the wild grass seeds 22 in water to maintain a predetermined temperature and to be in a state immediately before germination. Materials: peat moss, coconut fiber, and attapulgite) 21 and water 24 are added, and the water content is 10 to 80% (70 to 70%).
80% is optimal) as the vegetation layer 2
Incorporate in the mat.

As a second means, as shown in FIG. 2, in a packaging bag A, wild grass seeds 22, a curing material (base material) 21, and a fertilizer 23 are added in a weight ratio of about 1:10. : A mixture of about 5 and a mixture of an appropriate amount of water 24 are stored, and the packaging bag A is 10 if used for mechanical spraying.
~ 30 kg capacity, if it is hand-sprayed, it is made of an appropriate volume of polyethylene film, and the seed 22 may be as it is or may have been germinated, but when not germinated, the germination rate is low, Mix more than the above mixing ratio.

The above mixture may be placed in a packaging bag A in a sealed state or in a state in which some air is circulated, and the mixture may be stored for an appropriate period by controlling the temperature as it is. Germination is
Germination occurs when the temperature reaches a certain level of integrated temperature. If the bag A for packing the seed-mixed curing material (vegetation layer) is stored for an appropriate period of time in a greenhouse, room, or the like, the seeds 22
Is in a state immediately before germination. That is, cracks can be found in the seed shell. Therefore, the seed mixed curing material (vegetation part layer) 2 in the bag A is incorporated into the mat.

The flying seed growing prevention layer 3 comprises a water-soluble film 31, a coconut fiber layer 32, and a lattice network 33 from below.
The water-soluble film 31 is formed of a material that quickly dissolves in water, such as a starch film such as an oblate or a polyvinyl alcohol film, and is used to cover the vegetation layer 2 in front of a mat facility. is there.

The palm fiber layer 32 has a thickness of about 2 to 3 mm and is provided with a large number of small holes 321 and cuts 322. The small holes 321 are formed with a diameter of about 6 mm and spaced at intervals of 40 mm. The width of the palm fiber layer itself is formed to some extent rough, and the above-mentioned numerical values are merely numerical values of a processing machine. It is not formed. The coconut fiber layer 32 is for preventing the lower vegetation part layer 2 from scattering or flowing out of the vegetation part layer 2 when it is directly hit by rain. It is to prevent.

The lattice network 33 is a so-called hemp net, which prevents fibers from being released from the palm fiber layer 32. The suturing with the natural fiber thread 4 has a role of holding the whole in a thin sheet shape and also preventing the vegetation part layer 2 inside from being biased.

In the vegetation work using the vegetation mat, the mat is closely adhered to the surface of the ground on which vegetation is to be provided, and the mat is fixed to the ground surface using an appropriate pile. It is what you do. After fixing the vegetation mat, the vegetation layer 2
Seeds 22 germinate immediately and grow as the base material 21 as a breeding floor.
Buds breed on the mat through 22.

In particular, since the vegetation mat of the present invention has the vegetation layer 2 provided with the base material 21, it can be applied to the ground without the vegetation base, and the vegetation layer 2 containing the base material can be used.
Is covered with the washi paper 11 and the water-soluble film 31, so that the base material 2 of the vegetation section layer 2 can be transported before use.
1. No spillage of the seed 22, the fertilizer 23, etc. occurs.

Furthermore, the palm fiber layer 32 reduces the impact of rain when the roots are not yet firm after germination. At the same time, by providing the small holes 321 and the cuts 322, the germination and propagation are hindered. It is something that does not become. Of course, due to aging, all materials of the mat are returned to the soil, and there is no problem of environmental pollution.

[0023]

As described above, the present invention provides a vegetation mat in which a vegetation layer containing seeds immediately before germination is sandwiched between a base portion and a coating layer (a layer for preventing the growth of flying seeds). In the conventional vegetation mat having no vegetation, it is possible to sufficiently cope with a vegetation target site having an insufficient vegetation base, and to ensure the greening of wild grass.
