NOVELTY - Method of preparing organic compound fertilizer by fermenting animal manure, involves pulverizing animal manure, mixing swelling agent with the animal manure, pulverizing the manure particles, obtaining fermenting material comprising fine powder, wheat bran, organism humic acid, effective microorganism (EM) bacteria, zinc sulfate, ferric sulfate, ammonium nitrate, ammonium nitrate, boron and calcium chloride, fermenting the material, pulverizing the obtained material to obtain powder-shaped organic compound fertilizer mixture, and prilling and extruding the product.    USE - The method is useful for preparing organic compound fertilizer, which is used for crops.    ADVANTAGE - The method provides high survival rate of beneficial active bacteria in organic compound fertilizer, increases both production and income of product, and improves quality. The product supply enough and balanced nutrition for the crops, and can gradually eliminate pollution of soil and products caused by chemical fertilizer and pesticides through strong fermentation decomposition function of bacteria, which remolds soil for achieving green and inorganic standard.    DETAILED DESCRIPTION - Method of preparing organic compound fertilizer by fermenting animal manure, involves (a) pre-processing raw material, pulverizing animal manure and adjusting water content of the manure to 55-65%, where the manure has particle diameter of 0.5-1 cm, (b) mixing swelling agent (1.5-3.5%) with the animal manure, adding the mixture into a swelling machine, controlling temperature of the mixture to 200 degrees C and pressure at 10 kg/cm2 for swelling to obtain manure particles, pulverizing the manure particles using crushing machine and sieving the obtained material, and obtaining swelled fine powder having diameter of 1.0 mm or less, (c) obtaining fermenting material comprising (in wt.%) swelling fine powder (40-55), wheat bran (10.5-20.5), organism humic acid (0.4-0.6), effective microorganism (EM) bacteria (15-26), zinc sulfate (0.4-0.5), ferric sulfate (0.9-1.0), ammonium nitrate (1.8-2.0), ammonium nitrate (0.9-1.0), boron (0.2-0.3) and calcium chloride (0.03-0.04), (d) blending the material uniformly, transferring the fermenting material to a fermenting pool, where the material in the fermenting pool is stacked in one meter, and surface is covered by a breathable heat preservation material, fermenting the material at 30-35 degrees C for 10-14 days, controlling pH of the material to 5-6.5 during fermentation, reducing pH to 4.5-4.7 before opening the film, stabilizing the ventilating quality during the fermentation, opening the stacks and drying the fermented materials after fermenting for two times, where the temperature is not greater than 90 degrees C during drying, obtaining the fermented material with water content of 10-12 wt.%, and pulverizing the obtained material to obtain powder-shaped organic compound fertilizer mixture, and (e) prilling and extruding the organic compound fertilizer mixture into particle-shaped organic inorganic compound mixed fertilizer by dry type extruding prilling machine. An INDEPENDENT CLAIM is included for organic compound fertilizer, which is prepared by the above-mentioned method, where the fertilizer comprises bacteria (3.5x 108 colony forming unit (cfu)/g measured based on standard GB/T 4789-94 and NY.T 227-94), Saccharomycetes (5.5x 10(5) cfu/g), and mycete (4.8x 106 cfu/g).
