NOVELTY - Organic fertilizer is obtained by adding (in parts weight): edible rotting fungal residue (75-85) to Trichoderma fermented liquid (1-5) to obtain fermented material (I), adding rotten edible fungi residue (75-85) to actinomycetes fermented liquid (1-5) to obtain fermented material (II), uniformly mixing the fermented materials (I) and (II) in the weight ratio of 0.5-1:0.5-1, and drying the mixture at normal temperature until the moisture content is 20-22%.    USE - The organic fertilizer is useful for controlling diseases.    ADVANTAGE - The fertilizer is non-toxic, cost-effective and does not cause environmental pollution.    DETAILED DESCRIPTION - Organic fertilizer is obtained by adding (in parts weight): rotten edible fungi residue (75-85) to Trichoderma fermented liquid (1-5) to obtain fermented material (I), adding rotten edible fungi residue (75-85) to actinomycetes fermented liquid (1-5) to obtain fermented material (II), uniformly mixing the fermented materials (I) and (II) in the weight ratio of 0.5-1:0.5-1, and drying the mixture at normal temperature until the moisture content is 20-22%, where the edible rotting fungal residue is obtained by stacking and fermenting the residue (75-85), cake (15-20) and microorganism fermented inoculum (1-2), and drying the stack until the moisture content is 25-35%. An INDEPENDENT CLAIM is included for method for preparing the organic fertilizer, which involves (a) uniformly mixing (in parts weight): edible rotting fungal residue (75-85), cake (15-20) and microorganism fermented inoculum (1-2), regulating moisture content of the mixture to be 55-65 wt.%, carbon/nitrogen to 23-28 and pH to 7-7.5, stacking the mixture on trapezoidal cone to a height of 1.5-1.8 m, and making holes in the stack from top to bottom, where the number of hole is 10-15/square meter, (b) covering the hole with plastic film, subjecting the mixture to aerobic fermentation, warming the stack at 50 degrees C and fermenting for 5-7 days, cooling the mixture, turning the stack and fermenting mixture for 5-7 days, turning the stack every 5-7 days, fermenting the mixture for every 45-55 days, and drying the fermented organic fertilizer until the moisture content is 25-35 wt.%, (c) separately subjecting Trichoderma and actinomycetes to slant culture and liquid culture processes to obtain Trichoderma fermented liquid and actinomycetes fermented liquid, where the viable count of Trichoderma is more than 1x 108/ml and actinomycetes is more than 1x 108/ml, and (d) adding Trichoderma fermented liquid (1-5) to edible rotting fungal residue (95-99), stacking the mixture on rectangle stack to a height of 0.4-0.6 m, covering the stack with plastic film, controlling the temperature of the stack to 25-30 degrees C, turning the stack once every day, fermenting the stack for 6-10 days, adding actinomycetes fermented liquid (1-5) to fungal residue (95-99), stacking the mixture on rectangle stack to a height of 0.4-0.6 m, covering the stack with plastic film, controlling the temperature of the stack to 25-35 degrees C, turning the stack once every day and fermenting for 5-8 days, and uniformly mixing and drying the fermented material at normal temperature.
