NOVELTY - Organic fertilizer comprises 100-120 pts. wt. sheep manure, 30-34 pts. wt. chicken manure, 80-90 pts. wt. Taihu lake blue algae, 40-45 pts. wt. rice, 20-24 pts. wt. pineapple, 12-15 pts. wt. chinaberry leaf, 10-12 pts. wt. coal, 3-4 pts. wt. quicklime, 20-23 pts. wt. potassium dihydrogen phosphate, 30-34 pts. wt. diammonium phosphate, 18-20 pts. wt. carbamide, 3-4 pts. wt. effective microorganism, 4-6 pts. wt. coating agent and water. Coating agent comprises 2-3 pts. wt. dimethylamino ethyl acrylate, 1-2 pts. wt. dimethylamino ethyl methacrylate and 1-2 pts. wt. magnesium sulfate.    USE - Organic fertilizer.    ADVANTAGE - The organic fertilizer is economic and environment friendly, and strengthens crop metabolism, stimulates crop growth, promotes crop growth, reduces dosage of pesticide and fertilizer, and increases anti-cold capacity, drought resistance ability, crop quality, fertilizer utilization rate, soil water utilization efficiency and beneficial soil micro-organism.    DETAILED DESCRIPTION - Organic fertilizer comprises 100-120 pts. wt. sheep manure, 30-34 pts. wt. chicken manure, 80-90 pts. wt. Taihu lake blue algae, 40-45 pts. wt. rice, 20-24 pts. wt. pineapple, 12-15 pts. wt. chinaberry leaf, 10-12 pts. wt. coal, 3-4 pts. wt. quicklime, 20-23 pts. wt. potassium dihydrogen phosphate, 30-34 pts. wt. diammonium phosphate, 18-20 pts. wt. carbamide, 3-4 pts. wt. effective microorganism, 4-6 pts. wt. coating agent and balanced amount of water. Coating agent comprises 2-3 pts. wt. dimethylamino ethyl acrylate, 1-2 pts. wt. dimethylamino ethyl methacrylate, 1-2 pts. wt. magnesium sulfate, 2-3 pts. wt. 2-ethylhexyl phosphate, 1-2 pts. wt. triallyl cyanurate as cross-linking agent, 0.1-0.2 pts. wt. nano carbon and 2-3 pts. wt. stone powder, and is prepared by raw material, where obtained mixture is ground and dispersed to obtain coating agent. An INDEPENDENT CLAIM is included for a method for preparing organic fertilizer, which involves:    (A) crushing pineapple peel and chinaberry leaf into slag;    (B) crushing sheep manure, chicken manure and Taihu lake blue algae to obtain mixture that is mixed with rice hull powder using water vapor at 70-80 degrees C;    (C) fermenting obtained mixture with effective micro-organism in aerobic condition for 20-25 days;    (D) mixing potassium dihydrogen phosphate, diammonium phosphate and urea with fermented materials to obtain mixed fertilizer;    (E) grinding lignite and quicklime with water into slurry;    (F) mixing slurry and remaining components to obtain another mixture that is fermented for 5-10 days;    (G) drying fermented material to obtain dry granule; and    (H) mixing granule and mixed fertilizer to obtain product.
