NOVELTY - Organic-inorganic compound fertilizer comprises (in parts weight): fermented organic fertilizer (50-60), urea (14-18), diammonium phosphate (5-10), potassium sulfate (15-20), magnesium sulfate (2-4), zinc sulfate (0.5-1) and boric acid (0.2-0.5). The fermented organic fertilizer is obtained by stacking edible fungal residue (60-70), cake (15-20), microorganism fermented inoculum (10-15), fermenting the mixture, and drying the product until the moisture content is 25-35%.    USE - As organic-inorganic compound special fertilizer for grape.    ADVANTAGE - The fertilizer improves quality and oil fertility of grapes.    DETAILED DESCRIPTION - Organic-inorganic compound fertilizer comprises (in parts weight): fermented organic fertilizer (50-60), urea (14-18), diammonium phosphate (5-10), potassium sulfate (15-20), magnesium sulfate (2-4), zinc sulfate (0.5-1) and boric acid (0.2-0.5). The fermented organic fertilizer is obtained by stacking edible fungal residue (60-70), cake (15-20), microorganism fermented inoculum (10-15), fermenting the mixture, and drying the product until the moisture content is 25-35%. The microorganism fermented inoculum is prepared by mixing horse manure (10-20), edible fungal residue (75-85), ammonium nitrate (1-2), monopotassium phosphate (1.5-2) and magnesium sulfate (1.5-2) uniformly, regulating moisture content of the mixture to 60-65 wt.% and pH to 7-7.5, covering the materials with plastic film, stacking and fermenting the materials, heating the fermented materials at 50 degrees C, maintaining the temperature for 5-7 days, and turning the stack and fermenting for 5-7 days to obtain solid microorganism fermented inoculum. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) preparaing microorganism fermented inoculum by the above-mentioned method, (b) mixing edible fungal residue, cake and microorganism fermented inoculum, regulating moisture content of the mixture to 55-65% and mass ratio of carbon to nitrogen to 23-28 and pH to 7-7.5, stacking the mixture on trapezoid stack at a height of 1.5-1.8 m, drilling holes from top to bottom, where 10-15 holes are drilled in every m2, covering the plastic film, subjecting the mixture to carry aerobic fermentation, heating the stack to 50 degrees C and fermenting for 5-7 days, cooling the stack, turning the stack and fermenting for 5-7 days, fermenting the mixture for 45-55 days, and drying the fermented organic fertilizer until the moisture content is 25-35 wt.%, and (c) uniformly mixing the fermented organic fertilizer, urea powder of 80 mesh, diammonium phosphate, potassium sulfate, magnesium sulfate, zinc sulfate and boric acid, granulating the mixture, and drying and sieving the granules.
