NOVELTY - Fertilizer is prepared using e.g. edible fungi residue, fermented chicken manure, furfural residue, peanut stem, Chinaberry bark, peanut shell, basalt, urea, soil conditioner and suitable amount of water. The preparation method involves mixing above-mentioned raw materials with ammonium sulfate and suitable amount water to obtain slurry, heating the obtained slurry, adding ammonium persulfate to the obtained mixture, stirring and reacting mixture, heating and concentrating mixture to obtain paste, granulating obtained paste and drying to obtain product.    USE - The fertilizer is useful for fruit tress (claimed).    ADVANTAGE - The fertilizer is cost-effective, resistant to corrosion and environmentally-friendly, has good absorptive rate, delays generation of resistance to pests and prevents diseases of fruit tress.    DETAILED DESCRIPTION - Fertilizer is prepared using 100-120 pts. wt. edible fungi residue, 100-120 pts. wt. fermented chicken manure, 70-90 pts. wt. furfural residue, 45-50 pts. wt. peanut stem, 40-45 pts. wt. Chinaberry bark, 20-24 pts. wt. peanut shell, 10-12 pts. wt. basalt, 30-34 pts. wt. urea, 30-35 pts. wt. calcium superphosphate, 24-28 pts. wt. monoammonium phosphate, 2-3 pts. wt. manganese sulfate, 3-4 pts. wt. ammonium citrate, 4-5 pts. wt. humic acid sodium, 1-2 pts. wt. polyhydroxymethyl phenol ester, 6-9 pts. wt. effective microorganism (EM), 10-15 pts. wt. soil conditioner and suitable amount of water, where the soil conditioner comprises 120-130 pts. wt. weathered coal, 24-30 pts. wt. bamboo charcoal, 3-4 pts. wt. nano jade powder, 1-2 pts. wt. borax, 2-3 pts. wt. nano calcium carbonate, 10-12 pts. wt. peat, 2-3 pts. wt. boric acid, 9-12 pts. wt. Pinus contorta powder, 2-3 pts. wt. neopentyl glycol, 2-3 pts. wt. sodium selenite, 2-3 pts. wt. carboxymethyl cellulose, 2-3 pts. wt. zinc sulfate, 2-3 pts. wt. magnesium sulfate, 3-4 pts. wt. eucalyptus oil, 3-5 pts. wt. ammonium persulfate and suitable amount of water. The preparation method involves mixing the above-mentioned raw materials with ammonium sulfate and suitable amount water to obtain slurry, heating the obtained slurry at 80-90 degrees C, adding ammonium persulfate to the obtained mixture, stirring and reacting for 40-60 minutes, heating and concentrating the mixture to obtain paste, granulating obtained paste and drying to obtain product.
