NOVELTY - Preparation of peach tree fertilizer includes mixing materials including sheep manure and sugar slag, fermenting with microbial inoculum to get fermented product (FP); soaking, e.g. neem, honeycomb and lotus leaf in water to get insecticidal Chinese medicinal herbal concentrate (HC); hydrolyzing pig skin with sulfuric acid, adding, e.g. lime, zinc sulfate and manganese sulfate to generate amino acid chelate (AC); mixing monoammonium phosphate, calcium superphosphate, urea, potassium sulfate, FP, AC, HC and fertilizer liquid, granulating; and spraying with dispersion liquid.    USE - Method for preparing peach tree fertilizer (claimed).    ADVANTAGE - The method improves utilization rate, reduces fertilizing frequency, and reduces cost of fertilizer.    DETAILED DESCRIPTION - Preparation of peach tree fertilizer comprises mixing 40-60 pts. wt. greenhouse waste, 10-15 pts. wt. leaves, 10-15 pts. wt. wilt melon vine, 10-15 pts. wt. edible mushroom waste, 7-9 pts. wt. sheep manure, 10-12 pts. wt. sugar slag and 16-18 pts. wt. humic acid ammonium phosphate, crushing, mixing uniformly; adding 2-4 wt.% microbial inoculum, mixing uniformly, adjusting water content to 55-60 wt.% and pH value to 5-6; fermenting at 50-60 degrees C for 6-8 days, adding 2 wt.% organic fertilizer, turning every 2-3 days, continue fermenting at 60-70 degrees C for 10-14 days to obtain fermented product; soaking 3-5 pts. wt. peppermint leaf, 3-5 pts. wt. Anemone, 3-5 pts. wt. neem, 4-6 pts. wt. thunder god vine, 7-9 pts. wt. Eucalyptus leaf, 8-10 pts. wt. honeycomb, 4-6 pts. wt. Aconitum and 5-7 pts. wt. lotus leaf in water, boiling, taking liquid and concentrating to obtain insecticidal Chinese medicinal herbal concentrate; soaking pig skin in 22-33% sulfuric acid, hydrolyzing for 7-9 hours to generate amino acid, adding lime to neutralize, adding 3-5 wt.% carboxymethyl cellulose, boric acid, zinc sulfate and manganese sulfate to generate amino acid chelate; mixing 10-12 pts. wt. monoammonium phosphate, 8-9 pts. wt. calcium superphosphate, 9-11 pts. wt. urea, 10-12 pts. wt. potassium sulfate, adding fermented product, amino acid chelate, insecticidal Chinese medicinal herbal concentrate and fertilizer liquid, granulating; soaking slag in 10-15% hydrochloric acid for 3-5 hours, neutralizing with 10-12% sodium hydroxide solution, washing with deionized water until neutral, heating at 500-520 degrees C for 3-5 hours, adding bamboo nanocarbon, crushing into powder; mixing nanopowder and water, adding 2-4 wt.% sodium lauryl sulfate, 1-2 wt.% glycerol and 3-5 wt.% aluminum hydroxide, high speed stirring at 1200-1400 revolutions/minute to obtain dispersion liquid; and spraying liquid into biological medical fertilizer granule, and drying.
