According to the above-mentioned conventional slope greening method, since a net base is interposed between the slope and the greening base formed thereon, the adhesion of the greening base to the slope is low. A strong, stable greening base can be obtained,
Since the coil net extending in the horizontal direction is provided in parallel in the vertical direction on the surface of the wire mesh, steps at regular intervals are formed on the greening base, so that it is possible to prevent the outflow of seeds and to settle the incoming seeds well. However, it is desired that a greening base such as pack linter, bark compost, and chemical fertilizer in the greening base does not flow out by rainwater and a permanent fertilizer effect is provided on the greening base.
