NOVELTY - A soybean controlled release compound fertilizer, is prepared by: 1) fermenting 30-32 pts. wt. of fermented bean dregs, 26-27 pts. wt. of lees, 8-10 pts. wt. of dried sweet potato, 10-12 pts. wt. fulvic acid, 20-23 pts. wt. of urea, 40-42 pts. wt. of phosphate, 40-42 pts. wt. of potassium chloride, 1-2 pts. wt. zinc sulfate, 1-2 pts. wt. common Cnidium fruit, 3-5 pts. wt. of Radix sophorae flavescentis, 3-5 pts. wt. of unbracteolated spurge root, 1-2 pts. wt. of wingnut, and 5-8 pts. wt. of gelatine.    USE - As soybean controlled release compound fertilizer (claimed).    ADVANTAGE - The fertilizer improves quality of soybean; and provides higher nutrient composition contents, with composite food standard.    DETAILED DESCRIPTION - A soybean controlled release compound fertilizer, is prepared by following method: 1) preparing raw materials: 30-32 pts. wt. of fermented bean dregs, 26-27 pts. wt. of lees, 8-10 pts. wt. of dried sweet potato, 10-12 pts. wt. fulvic acid, 20-23 pts. wt. of urea, 40-42 pts. wt. of phosphate, 40-42 pts. wt. of potassium chloride, 1-2 pts. wt. zinc sulfate, 1-2 pts. wt. common Cnidium fruit, 3-5 pts. wt. of Radix sophorae flavescentis, 3-5 pts. wt. of unbracteolated spurge root, 1-2 pts. wt. of wingnut, 5-8 pts. wt. of gelatine; 2) crushing fermented bean dregs, lees, dried sweet potato, fulvic acid and matrine, sieving through 400 meshes molecular sieve to obtain organic powder, smashing the Fructus cnidii, Euphorbia and wingnut; passing by 400 meshes molecular sieve to obtain antibacterial powder, urea, phosphate, potassium chloride and zinc sulfate; grinding, sieving by 400 meshes molecular sieve to obtain the inorganic powder; adding water to gelatine at 30-60 degrees C to fully dissolve to obtain the gelatine solution; 3) taking 90% gelatine solution, 40% of inorganic powder, 60% antibacterial powder and 40% organic powder, and adding 30-60 degrees C water to paste, then squeezing and swelling, preparing into granule with grain diameter of expanded particles of 0.3-0.8 cm; 4) taking 30% of inorganic powder, 20% antibacterial powder and 30% organic powder, and adding 35-37 degrees C water to paste, then adding swelling granule, stirring them uniformly, naturally drying to obtain the compound particle; 5) taking 10% glutin solution and adding 20% water, after mixing evenly, spraying the composite particle surface, drying at less than 30 degrees C to obtain controlled release particles; and 6) spraying the rest powder and inorganic antibacterial powder and water in controlled release particle surface, at less than 30 degrees C to obtain the product.
