NOVELTY - A corn special fertilizer, is prepared by the following raw materials: 20-23 pts. wt. of silkworm sand, 23-25 pts. wt. of lees, 8-10 pts. wt. of fulvic acid, 20-22 pts. wt. of fermented bean dregs, 8-10 pts. wt. of sorghum, 4-6 pts. wt. of peanut cake, 22-25 pts. wt. of corn straw fermentation liquid, 5-7 pts. wt. of gelatine, 12-15 pts. wt. of urea, 20-23 pts. wt. of diammonium phosphate and 18-20 pts. wt. of potassium sulfate.    USE - As corn special fertilizer (claimed).    ADVANTAGE - The corn special fertilizer effectively improves the yield and the quality of the corn. The content of the nutrient component of the corn has high energy composite food standard.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the corn special fertilizer, involving: (1) taking urea, diammonium phosphate and potassium sulfate; adding water to dissolve; preparing into inorganic liquid fertilizer; crushing broomcorn and peanut cake; (2) taking 1/3 pts. wt. of inorganic liquid fertilizer, completely absorbed by the silkworm feculae, and reacting at 30-40 degrees C under the condition of drying, pulverizing, sieving through 400 meshes molecular sieve to obtain silkworm powder; (3) adding lees, fulvic acid, bean dregs yeast for fermentation straw, sorghum, and peanut cake; mixing uniformly; standing for 2-3 days at 30-40 degrees C under the condition of drying, and crushing to obtain the organic fertilizer; (4) taking 1/2 parts of inorganic liquid fertilizer, adding gelatine, heating to 30-40 degrees C, and completely dissolving gelatine to obtain the gelatine solution; (5) granulating 90% of gelatine solution to the organic fertilizer, and drying to obtain the composite fertilizer core; (6) soaking rest glutin solution to compound fertilizer core, soaking the composite fertilizer core grain surface, and then adding silkworm powder, completely covering silkworm powder on the composite fertilizer core grain surface, naturally drying to obtain composite fertilizer particle; and (7) adding the rest of inorganic liquid fertilizer for several times to the compound fertilizer particle spraying, and naturally drying to obtain the product.
