Description of the Related Art Conventionally, as one of the methods for protecting slopes and greening them, a vegetation mat to which vegetative seeds are attached and sandbags with stretched grass are provided by installing a grid-like frame along the slope. There was a method of placing sandbags in a bag and placing them in the divisions of the lattice-shaped method frame. This method has a problem that it is difficult to obtain the adhesion of the vegetation mat and the sandbag to the uneven surface of the slope. Moreover, since the sandbag containing the soil is heavy, it is very difficult and dangerous to move and carry it to a high place or a sloping ground, and the construction period is long.

があらわになる部分があり、景観上問題もあった。As another method, a polyethylene net or a wire mesh lath net is stretched over the slope, and a vegetation material containing plant seeds is sprayed to protect the slope and greenery. was there. However, such a method requires a large-scale plant for spraying the vegetation material, and the sprayed vegetation material flows out due to rainfall, etc., so that the plant does not settle and the net made of polyethylene or the like is exposed. There was also a problem with the scenery.

が困難であった。In order to solve such problems, plant seeds,
A mat having a double structure on the front surface and the back surface, in which a fertilizer, a soil improving agent and the like are enclosed, has been proposed. However, since the material on the front surface and the back surface is a corrosive material, the mat is corroded before the plant grows sufficiently, and seeds, fertilizers, soil conditioners and the like cannot be retained. For this reason, the strength of the vegetation base necessary for growing plants cannot be obtained, and after corrosion of the mat, seeds may be washed out by wind and rain, or blown off, protecting slopes, etc., greening effect Was difficult to obtain.

もに一定期間経過後、腐食する素材で構成されている。In order to solve such problems, it has been proposed to use a corrosion resistant material in which the antiseptic time of the net enclosing the fertilizer, the seed and the soil improving agent is delayed by various methods. For example, a method in which the material for the net is a blend of corrosive fibers and synthetic fibers having corrosion resistance (Japanese Patent Laid-Open No. 6-4
1973, etc.), a method of mixing a woven fiber of a high-molecular emulsion, a water-soluble polymer, viscose, and a corrosive fiber (JP-A-6-41975, etc.), antiseptic treatment, antifungal treatment, antibacterial treatment, A method of using a corrosive material whose corrosion time is delayed by water repellency treatment or the like (Japanese Patent Laid-Open No. 6-4197).
No. 4) is proposed. These methods include seeds,
After maintaining fertilizer and soil improver for a certain period of time to assist the growth of plants, the material of the net corrodes and becomes homogenized with the soil, protecting slopes and solving landscape problems. It is intended for. Each of these is composed of a front net and a back net, and both nets are made of a material that corrodes after a certain period of time.

おそれがある。However, in the case of using mixed fiber as a raw material, after the corrosive fiber is corroded, the corrosion resistant synthetic fiber becomes a fragmented residue and remains as an impurity in soil. become. In addition, in a net made of a corrosion-resistant material by delaying the corrosion time with various chemicals, there is a possibility that soil may be contaminated by antiseptic chemicals and water-repellent chemicals. In addition, after the chemical-treated net is corroded, only the root of the plant can obtain the strength of the vegetation base, and the soil and fertilizer, or even the plant itself may flow out due to the erosion of the topsoil due to rainfall or the like. .

があった。[0008] On the other hand, when the plant is an annual plant and dies in autumn and winter, the effect of retaining the topsoil by the roots is weakened, and seeds, soil, etc. may be discharged by wind and rain. As a result, the protection of slopes and the retention of nutrients on the land are impaired.
There was a problem that the landscape such as slopes and the effect of maintenance would decrease after the first year.

ることができる。After rooting of tree seeds such as yashabushi and yamahagi, the roots are deeply rooted in the soil and the back net is firmly pressed into the soil. Also, when tree seeds are used, by the time the vegetation grows and the stems and roots grow to such an extent that the nets of the back net are overwhelmed, the existence of the back net will reach the purpose and strengthen the slopes, etc. The plant itself can replace the long-term greening effect of the surface. These tree seeds grow relatively slowly compared to other flowers,
However, once it grows, it can be used for several decades to protect trees such as slopes. For this reason, when using tree seeds, it is effective to use them in combination with annual or perennial seeds. In other words, during the one or two years until the vegetation is firmly rooted in the soil, the annual and perennial plants play a role of strengthening the protection of the slopes and the greening of the slopes along with the back net, and thus the plant cultivation according to the present invention. It is possible to strengthen the protection such as slopes for one to two years to several decades after laying the mat for construction.

Any material may be used regardless of whether it is artificial or not, but one that does not flow out due to rainwater is preferable. This soil is at least necessary until the seed 30 germinates and the root 26 is extended to the soil of the slope 28, and is not particularly limited. Further, the water retention agent is required when the water retaining capacity of the soil put in the bag portion 34 is small, so that the soil in the bag portion 34 is not easily dried. Next, the soil improving agent is for improving the soil in which the soil inside has been exposed due to construction or the like.
