PURPOSE: A composition for foresting in slope using general soil as a main component and inorganic materials as hydration reaction materials is provided, which stabilizes the soil in a short time, prevents the loss of soil by rain and promotes germination and growth of plants. CONSTITUTION: The forestation composition comprises 50-98pts.wt. of plant growing soil, 0.5-10pts.wt. of soil stabilization products, 0.5-10pts.wt. of preventive soil cementation products, 0.05-2pts.wt. of seeds and 50-100pts.wt. of water, The plant growing soil comprises 40-80pts.wt. of general soil composed of 20-70pts.wt. of clay and 30-80pts.wt of sandy soil, 2-25pts.wt. of pitmoss, 5-25pts.wt. of organic fertilizer and 1-10pts.wt. of compound fertilizer. The soil stabilization products comprises 10-80pts.wt. of adhesive Al2O3-based cement, 20-85pts.wt. of volcanic ash or weathering soil of tuff, 1-10pts.wt. of zeolite, 1-10pts.wt. of diatom earth and 1-20pts.wt. of calcined gypsum, in which Ca(OH)2 formed from the hydration of cement is reacted with the weathering soil of tuff to yield insoluble compound with a porous structure. The preventive soil cementation products comprises 1-20pts.wt. of Al powder, 10-90pts.wt. of vermiculite and 1-15pts.wt. of plasticizer. |
