PURPOSE:To realize good greens-planting works by controlling the run-off of soil from the slope by a method in which a net material consisting of a honeycomb- shaped polygonal cellular frame and a rough meshed fishing net is fixed to the slope, replaced soil is applied, and seeds and fertilizer are spread on the soil. CONSTITUTION:A frame 2 is of a honeycomb-shaped polygonal cellular form and is made by joining tape-like base materials with given intervals, and a net material 4 is formed of a rough fishing net. The frame 2 is extended over a slope 1 and fixed to the slope 1 with anchors 3, and the net material 4 is laid and fixed to the slope 1 with anchors 5. Replaced soil is applied on them by spreading or spraying, and seeds and fertilizer are spread over the soil which is held by the flame 2 and the net material 4. The run-off of the soil by rain water, wind, etc., can thus be controlled and therefore, good greens-planting work can be realized even on steep slope surface. |
