DETAILED DESCRIPTION - Composite fertilizer comprises 15-19 pts. wt. potassium chloride, 1-2 pts. wt. borax, 1-2 pts. wt. ammonium molybdate, 2-3 pts. wt. ferrous sulfate, 44-49 pts. wt. molasses, 2-3 pts. wt. polyepoxysuccinic acid, 25-29 pts. wt. sisal fiber, 26-29 pts. wt. urea, 22-26 pts. wt. diammonium phosphate, 6-9 pts. wt. maifanite, 7-9 pts. wt. vermiculite, 40-45 pts. wt. wheat bran, 34-38 pts. wt. sugarcane bagasse, 5-7 pts. wt. effective microorganism inoculant, 7-9 pts. wt. soil conditioner and balance amount of water. The soil conditioner comprises 10-20 pts. wt. alkyd resin, 1-2 pts. wt. nano toner, 4-5 pts. wt. sodium metasilicate, 17-19 pts. wt. methyl methacrylate, 3-4 pts. wt. selenium yeast, 2-3 pts. wt. copper sulfate, 2-3 pts. wt. zinc gluconate, 1-2 pts. wt. magnesium chloride, 2-3 pts. wt. ammonium molybdate, 1-2 pts. wt. boric acid, 4-6 pts. wt. dipentaerythritol hexaacrylate, 30-40 pts. wt. vinegar, 2-3 pts. wt. chitosan, 1-2 pts. wt. eucalyptus oil, 3-5 pts. wt. tripropylene glycol diacrylate, 5-6 pts. wt. alum and 1-2 pts. wt. iron slag. The soil conditioner is prepared by mixing dipentaerythritol hexaacrylate, tripropylene glycol diacrylate, alkyd resin, nano toner, eucalyptus oil and iron slag, heating the mixture at 65-75 degrees C to form a mixture, adding alum, chitosan, ammonium molybdate, sodium metasilicate, methyl methacrylate, selenium yeast, copper sulfate, zinc gluconate, magnesium chloride, and boric acid to the hot mixture and then adding vinegar, and stirring the mixture in a high speed disperser to obtain a slurry. An INDEPENDENT CLAIM is included for preparing composite fertilizer comprising mixing potassium chloride, borax, ammonium molybdate, ferrous sulfate and diammonium phosphate, adding water to the mixture and then mixing, adding soil conditioner, maifanite, vermiculite and polyepoxysuccinic acid to the mixture and then stirring to obtain a slurry, concentrating the slurry and then drying, granulating the dried product, adding effective microorganisms inoculant, sugarcane bagasse, sisal fiber, molasses and wheat bran to the granulated product, reducing the moisture content of the mixture to 45-50%, adding urea to the mixture and then stirring, fermenting the mixture under anaerobic conditions for 24-30 days at room temperature, and drying the fermented product and then granulating.
