NOVELTY - Producing organic fertilizer comprises taking organic raw material, mixing weathered coal and farmyard manure to obtain organic raw material and then adding ammonium hydrogen carbonate, mono-ammonium phosphate and uniformly doping, stacking ferment pool to ferment for one circle and spraying the material with sodium hydroxide solution and weathered coal, uniformly stacking circle and then turning into microbial inoculum, adding weathered coal and farm fertilizer into organic raw material, stacking the material, ventilating and fermenting circle to obtain cured organic raw material.    USE - The method is useful for producing organic fertilizer (claimed).    ADVANTAGE - The method economically and effectively produces the organic fertilizer with high hardness and strong continuity and operability.    DETAILED DESCRIPTION - Producing organic fertilizer, comprises taking organic raw material, mixing weathered coal and farmyard manure according to weight ratio of 1-1.5:1-2 to obtain organic raw material and then adding 0.1-0.2 pts. wt. of ammonium hydrogen carbonate, 0.03-0.05 pts. wt. of mono-ammonium phosphate and uniformly doping, stacking ferment pool to ferment for one circle and spraying the material with 3-10 mass% of sodium hydroxide solution and 0.4-1 mass% of weathered coal, uniformly stacking circle and then turning into microbial inoculum, adding weathered coal and farm fertilizer into 0.05-0.3 mass% of organic raw material, stacking the material at 40-60 degrees C for 2-5 days, ventilating and fermenting circle to obtain cured organic raw material, granulating base material, curing the organic raw material or inorganic raw material according to weight ratio of 1:0.2-0.4, crushing the material into 80-100 meshes and then pelleting to obtain base material, pelleting the base material to heat at 50-60 degrees C, spraying atomized urea-formaldehyde humic acid activated ripener for pelleting, pelleting base material adhesive to granulate, atomizing ripener to 10-90 mass% of cure organic raw material, processing the pelletizer to form particle into dryer and then drying at temperature of 80-95 degrees C and until the moisture content is 10-20% adding dried particles into cooler, cooling to room temperature, filtering the material, removing the unqualified particle, passing the particles into bag, and sieving the qualified particles into the coating machine and then lapping by 0.1-0.2 mass% of organic vegetable oil.
