NOVELTY - Pear planting organic fertilizer comprises 14-16 pts. wt. plant straw, 12-14 pts. wt. rice bran, 16-18 pts. wt. cottonseed cake, 8-10 pts. wt. medical stone, 6-8 pts. wt. lime powder, 8-10 pts. wt. plant ash, 2-3 pts. wt. gelatin powder, 3-5 pts. wt. Effective Microorganisms (EM) biological liquid, 4-6 pts. wt. potassium humate, 12-14 pts. wt. ammonium nitrate fertilizer, 5-7 pts. wt. copper sulfate, 6-8 pts. wt. ammonium bicarbonate, 2-3 pts. wt. magnesium chloride, 4-5 pts. wt. auxiliary agent, and balance water.    USE - Pear planting organic fertilizer.    ADVANTAGE - The organic fertilizer has slow release fertilizing effect, reduced application times and increased efficiency, and is environment-friendly. Further, the fertilizer is capable of avoiding fertilizer loss caused by rain erosion.    DETAILED DESCRIPTION - Pear planting organic fertilizer comprises 14-16 pts. wt. plant straw, 12-14 pts. wt. rice bran, 16-18 pts. wt. cottonseed cake, 8-10 pts. wt. medical stone, 6-8 pts. wt. lime powder, 8-10 pts. wt. plant ash, 2-3 pts. wt. gelatin powder, 3-5 pts. wt. EM biological liquid, 4-6 pts. wt. potassium humate, 12-14 pts. wt. ammonium nitrate fertilizer, 5-7 pts. wt. copper sulfate, 6-8 pts. wt. ammonium bicarbonate, 2-3 pts. wt. magnesium chloride, 4-5 pts. wt. auxiliary agent, and balance water. The auxiliary agent comprises 1-2 pts. wt. zinc gluconate, 0.5-1.5 pts. wt. carbon nanopowder, 0.8-1.4 pts. wt. wintergreen oil, 2-3 pts. wt. medical stone powder, 0.5-1 pts. wt. ammonium persulfate, 10-15 pts. wt. nano iron ore tailings, 3-5 pts. wt. methyl methacrylate, 4-6 pts. wt. borax, 2-3 pts. wt. glycerol, and balance water. The auxiliary agent is prepared by mixing glycerol and water, dissolving, then adding zinc gluconate, carbon nanopowder, wintergreen oil, medical stone powder, methyl methacrylate, and ammonium persulfate, heating to 80-90 degrees C, stirring for 20-30 minutes, then adding nano iron ore tailings and borax, forming into paste, drying, and crushing. An INDEPENDENT CLAIM is included for preparation of the organic fertilizer, comprising:    (A) adding gelatin powder with water at ratio of 1:150, stirring and heating to dissolve, crushing medical stone into fine sand-like particles, adding the medical stone fine particles, heating and stirring for 30-40 minutes, naturally cooling to room temperature, and filtering the medical stone fine particles;    (B) crushing plant straw, adding rice bran, cottonseed cake, medical stone, lime powder and plant ash to obtain mixed organic material, then adding EM biological liquid with water at ratio of 1:10 and dissolving and spraying this solution to the mixed organic material, uniformly mixing, adjusting water content to 3-40%, and stacking to ferment for 12-16 days at 37-40 degrees C;    (C) mixing potassium humate, ammonium nitrate fertilizer, copper sulfate, ammonium bicarbonate, magnesium chloride, and the auxiliary agent, adding 1-14 times water, stirring and heating to dissolve to obtain aqueous solution; and    (D) mixing medical stone fine particles and organic fermented material, rolling and stirring while uniformly spraying the aqueous solution, then drying to water content of less than 20%, ultra micro crushing, and granulating to particle diameter of 4-6 mm.
