USE - Fertilizer.    ADVANTAGE - The fertilizer has long-lasting effect, promotes the growth of crop, restrains the growth of pathogenic microorganism, and increases the product quality.    DETAILED DESCRIPTION - Fertilizer comprises 65-85 pts. wt. sugarcane filter cake, 2-3 pts. wt. boric acid, 1-2 pts. wt. zinc sulfate, 2-4 pts. wt. chitosan, 3-4 pts. wt. borax, 2-3 pts. wt. molybdate, 29-31 pts. wt. ash tree, 4-6 pts. wt. limestone powder, 30-35 pts. wt. peptone, 14-18 pts. wt. urea, 24-26 pts. wt. humic acid, 4-5 pts. wt. rhizoma smilacis glabrae, 2-4 pts. wt. silicate, 4-7 pts. wt. silicon hydroxyapatite and 5-7 pts. wt. auxiliary agent, where the auxiliary agent comprises 4-6 pts. wt. iron ore powder, 3-6 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (EDDHA) chelated iron, 8-10 pts. wt. fresh konjac, 3-4 pts. wt. magnesium amino acid chelate, 3-4 pts. wt. copper amino acid chelate, 3-4 pts. wt. manganese amino acid chelate, 1-3 pts. wt. methyl methacrylate, 0.1-0.2 pts. wt. N-butyl thiophosphoric triamide, 12-16 pts. wt. fresh grass and 8-12 pts. wt. coral rock ash. The auxiliary agent is prepared by cleaning the fresh grass and konjac using water, crushing the materials and extracting the mixture, filtering the liquid, adding the remaining raw materials, stirring uniformly, wet granulating the mixture, coating the granules and drying the coated granules. An INDEPENDENT CLAIM is included for method of preparing the fertilizer, which involves adding proper amount of water to the fermentation material, inoculating the effective microorganisms, performing anaerobic fermentation for 6-10 days, adding the other raw materials, performing aerobic fermentation for 60-72 hours, drying the fermented material, adding auxiliary agent, stirring uniformly, formulating the mixture into particles of 8-12 mm and drying the particles under low temperature.
