TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Components: The forest waste is the bark, branch, coconut-husk, rough scobs, saw-dust, rice hull, peanut shuck, corn core and Chinese medicinal residue. Preferred Method: The method involves shattering the rough material of the bark, branch, peanut shuck, corn core and Chinese medicinal residue using the shattering machine with screen of 4-6 mm and adding the shattered materials to coconut-husk, rough scobs, saw-dust and rice hulls directly, fermenting the above materials in a ferment site facing the sunshine with flowing wind outdoors, stacking the fermented material above the air tube with the stack width of 6 m and height of 3 m and adding (in %) carbamide (0.1), potassium dihydrogen phosphate (0.2) and EM bacteria or the animal dejecta (0.2-0.5) into the stack to fasten the ferment. The process of carbonizing the rice-hulls involves building a stove range with the inner diameter of 1 m and height of 0.6 m, positioning one end of one or two iron tubes with the inner diameter of 50-100 mm and length of 2 m to be inclined in the stove range and the other end outside the stove range, burning the lumbers in the stove, covering the stove by a iron sheet lid with the diameter more than the diameter of the stove range distributed with small holes, pouring the dry rice-hull on the lid until covering the lid compactly, observing the carbonization condition of the rice-hulls, pouring more rice-hulls when the rice-hulls becomes black, repeating to pour more rice-hulls to increase gradually the bulk of the carbonized rice-hulls, removing the rice-hulls which are not carbonized on the surface when most of the rice-hulls are carbonized to be black, damping completely the rice-hulls using clean water or positioning and cooling the carbonized rice-hull on the ground and drying the carbonized rice hulls by wind or sunshine to obtain carbonized hulls with 15-20% of water, positioning the substrate with 15-20% of water in the oscillator with 4 mm of hole diameter, oscillating and screening the materials to remove large particles, mixing (in ratio) the turf, coconut-husk and carbonized rice-hull (3:3:4) or the turf and carbonized rice-hull (6:4) or the bark, coconut-husk, scobs and corn cone (2:4:4) or the turf, coconut-husk and bark (3:3:4) or the turf, coconut-husk, and scobs (3:3:4) or the bark, coconut-husk and Chinese medicinal residue (2:5:3) or the scobs, coconut-husk, Chinese medicine residue (2:4:4) or the Chinese medicinal residue, coconut-husk and corn core (3:3:4) or the turf, coconut-husk and corn core (3:3:4), transferring the raw material into the moulding machine and shaping the substrate to intestine-shaped substrate using the non-woven cloth with 122-160 mm width and cutting the intestine-shaped substrate into section (80-100 mm) for culturing the seedling or storing the substrate and cutting the substrate at the time of use and wetting the intestine-shaped substrate to avoid laxity of the substrate.
