Also, various materials have been proposed in which seeds and fertilizers of vegetation plants are attached to a net body or the like to cover a slope or the like so that vegetation is performed. However, in any of the above cases, so-called vegetation plants are mainly used as vegetation plants, and it has been difficult to perform vegetation throughout the year or for a long time.

In recent years, it has been said that vegetation of non-leguminous woody plants is effective in protecting slopes from the standpoints of forestation, environmental greening and environmental protection. In terms of slopes, there is an increasing demand for early forestation, and as a method to respond to this demand, the seeding method by mixed seeding of grass and wood is mainly used, but the growth of wood is much higher than that of grass. There was a problem that the trees could not grow because they were so slow that they could not grow.
In addition, slopes and shoulders of roads are subject to severe natural environments, so in order to sufficiently grow non-legume woody plants, it is necessary that the same growth conditions as in cultivated land are prepared. Met.

EXAMPLES Next, the vegetation method and vegetation substrate 1 according to the present invention
0 and the vegetation sheet body 50 will be described in detail according to the embodiment shown in the drawings. First, the vegetation method by spraying is described. First, a vegetation substrate 10 in which Francia fungus 40 is mixed with plant seed 20, fertilizer 30, soil conditioner 31, and the like.
Are mixed in a tank with sufficient stirring to form a slurry, which is sprayed on the slope 70 as shown in FIG. 2, or sprayed by an appropriate means.

At this time, as the material to be put in the tank, in addition to the above-mentioned vegetation base material 10, water which is made into a slurry and which is necessary for the growth of the plant and a water retention agent for preventing the sprayed layer of the slope 70 from drying are used. Alternatively, organic soil or the like for improving the water retention property and fertilization property of the spray layer may be mixed.
Further, as shown in FIG. 1, a protective net 71 may be stretched on the slope 70 before the spraying work. This is because it has the effect of preventing the sprayed material from being washed away, and the roots of the plant are protected by a protective net 71 as the plant grows on the slope 70.
This is because the blowing layer is tightly bound while being entangled with the slab to form a strong board and protect the slope 70. Of course, in this vegetation method, it is not always necessary to spray the Frankia bacterium 40 at the same time as the vegetation base material 10 is sprayed. For example, immediately after the vegetation base material 10 is sprayed, the Frankia bacterium 40 is co-cultured with the culture medium. It may be carried out by spraying.

Next, the vegetation base material 10 will be described. The vegetation base material 10 is a plant seed 20, a fertilizer 30, and a soil improving material 3.
