NOVELTY - A winter wheat base fertilizer includes 10-20 pts.wt. tea seed cake powder, 18-20 pts.wt. diammonium phosphate, 20-30 pts.wt. fly ash, 10-12 pts.wt. sepiolite, 5-7 pts.wt. bamboo charcoal, 3-4 pts.wt. Celastrus vine powder, 3-4 pts.wt. oleander powder, 10-15 pts.wt. oleander bagasse, 10-15 pts.wt. iron ore sand, 18-22 pts.wt. cow manure, 3-4 pts.wt. carboxymethyl cellulose, 15-20 pts.wt. of 30% sulfuric acid, 5-10 pts.wt. lime, 10-15 pts.wt. bean pulp, and 4-6 pts.wt. epoxidized soybean oil.    USE - A winter wheat base fertilizer.    ADVANTAGE - The fertilizer has improved utilization rate, has slow release effect, reduces fertilizing amount, reduces pesticide residue, and improves yield and quality of winter wheat.    DETAILED DESCRIPTION - A winter wheat base fertilizer comprises 10-20 pts.wt. tea seed cake powder, 4-5 pts.wt. coated urea, 18-20 pts.wt. diammonium phosphate, 5-8 pts.wt. coated potassium chloride, 20-30 pts.wt. fly ash, 1-2 pts.wt. ferrous sulfate, 0.1-0.5 pts.wt. zinc sulfate, 0.1-0.3 pts.wt. boric acid, 10-12 pts.wt. sepiolite, 5-7 pts.wt. bamboo charcoal, 3-4 pts.wt. Celastrus vine powder, 3-4 pts.wt. oleander powder, 10-15 pts.wt. oleander bagasse, 10-15 pts.wt. iron ore sand, 18-22 pts.wt. cow manure, 3-4 pts.wt. carboxymethyl cellulose, 15-20 pts.wt. of 30% sulfuric acid, 5-10 pts.wt. lime, 10-15 pts.wt. bean pulp, and 4-6 pts.wt. epoxidized soybean oil. An INDEPENDENT CLAIM is included for preparing the winter wheat base fertilizer, comprising adding soybean powder in 0% sulfuric acid, hydrolyzing at 100-110 degrees C for 1-2 hours to generate amino acid, adding lime to neutralize pH value at 6-6.8, adding carboxymethyl cellulose, adding ferrous sulfate, zinc sulfate, and boric acid, dissolving, reacting at 90-105 degrees C for 5-6 hours to generate amino acid chelated fertilizer solution; sintering iron ore for 6-8 hours at 400-500 degrees C, adding epoxidized soybean oil, grinding into nanopowder, and mixing with fly ash; high temperature composting fermentation of organic fertilizer, adding tea seed cake powder and bagasse, adding cow manure into Bacillus subtilis, uniformly mixing, piling, turning for 5-10 days, and fermenting at 60-65 degrees C for 30-40 days to obtain an organic fertilizer; mixing coated urea, diammonium phosphate, potassium chloride, crushing with sepiolite, bamboo charcoal, and fermented organic fertilizer, crushing, and passing by 100-200 mesh sieve; uniformly mixing Celastrus vine powder and oleander powder; and adding amino acid chelated fertilizer solution, uniformly stirring after granulating, and spraying epoxy soybean oil to coat film.
