NOVELTY - Fertilizer comprises acid whey, gelatin, pig manure, biogas sludge, Pachyrhizus, traditional Chinese medicine slag, carbamide, ammonium sulfate, animal viscera, fused calcium-magnesium phosphate, potassium dihydrogen phosphate, turpentine oil, brown sugar, lactic acid, acrylamide, microbial inoculum, soil modifying agent, and water.    USE - The fertilizer is useful for blueberries (claimed).    ADVANTAGE - The eco-friendly fertilizer has long lasting effect, reduces soil erosion and loosens the soil to prevent caking, promotes blueberries to absorb nutrients from the soil, and regulates the resistance ability in blueberries.    DETAILED DESCRIPTION - Fertilizer comprises 96-104 pts. wt. acid whey, 5-8 pts. wt. gelatin, 45-49 pts. wt. pig manure, 50-52 pts. wt. biogas sludge, 23-27 pts. wt. Pachyrhizus, 30-35 pts. wt. traditional Chinese medicine slag, 9-15 pts. wt. carbamide, 13-16 pts. wt. ammonium sulfate, 21-26 pts. wt. animal viscera, 2-4 pts. wt. fused calcium-magnesium phosphate, 12-16 pts. wt. potassium dihydrogen phosphate, 1-2 pts. wt. turpentine oil, 11-14 pts. wt. brown sugar, 0.02-0.04 pts. wt. lactic acid, 2-4 pts. wt. acrylamide, 8-12 pts. wt. microbial inoculum, 8-11 pts. wt. soil modifying agent, and proper amount of water. The soil modifying agent comprises 3-6 pts. wt. silica micropowder, 30-36 pts. wt. peat, 4-6 pts. wt. ethylene glycol dimethacrylate, 15-18 pts. wt. bentonite, 2-3 pts. wt. sulfur, 1-2 pts. wt. polymeric ferric sulfate, 0.3-0.8 pts. wt. borax, 0.5-1 pts. wt. selenium-rich yeast, 0.2-0.6 pts. wt. copper sulfate, 0.5-1 pts. wt. zinc acetate, 0.2-0.4 pts. wt. calcium silicate, 0.02-0.05 pts. wt. potassium, 0.2-0.5 pts. wt. sodium dodecyl benzene sulfonate, 2-3 pts. wt. hydroxypropyl cellulose, 0.5-1 pts. wt. sodium alginate, 0.3-0.5 pts. wt. polyethylene glycol, and 0.2-0.5 pts. wt. glycerol. The soil modifying agent is prepared by mixing and grinding ethylene glycol dimethacrylate, bentonite, borax, selenium-rich yeast, copper sulfate, zinc acetate calcium and silicate grinding into fine powder, adding polymeric ferric sulfate, silicon micropowder and potassium, uniformly grinding and then dispersing the mixture, adding sodium dodecyl benzene sulfonate and alginate, uniformly mixture and then adding to a granulator, adding hydroxypropyl cellulose to 7 times the amount of water and then adding polyethylene glycol and glycerol uniformly stirring the mixture in a fluidization bed, atomizing, drying at room temperature and then cooling. An INDEPENDENT CLAIM is included for preparing the fertilizer comprising (a) adding pig manure, Pachyrhizus, biogas sludge, traditional Chinese medicine residue, animal viscera, lactic acid, brown sugar and EM microbial inoculum to acid whey, uniformly stirring the mixture, sealing the mixture, maintaining the moisture content to 43-46% and then fermenting under a normal temperature without oxygen for 24-27 days, where the mixture is turned once for every 3-4 days, drying and then granulator into 0.05 mm powder, (b) crushing fused calcium-magnesium phosphate, ammonium sulfate, potassium dihydrogen phosphate, acrylamide and turpentine oil and then granulating, and (c) passing the granulated product of step (b) to a coated pan, controlling the temperature to 40-50 degrees C, spraying the pan with urea, adding the product of step (a), continuously spraying urea to the surface to form a uniform coating, hot air drying at 50-60 degrees C, cooling to room temperature, adding soil modifying agent and mixing uniformly.
