DETAILED DESCRIPTION - Furfural residue tree fertilizer comprises: 200-230 pts. wt. of soybean meal, 100-120 pts. wt. of deer dung, 50-55 of furfural slag, 30-35 pts. wt. of bead tree root, 40-45 pts. wt. of cotton seed hull, 50-55 pts. wt. of ammonium sulfate, 30-34 pts. wt. of urea, 20-24 pts. wt. of mulberry, 10-12 pts. wt. of tobacco, 12-16 pts. wt. of potassium chloride, 3-4 pts. wt. of ferrous sulfate, 3-4 pts. wt. of borax, 4-5 pts .wt. of zinc gluconate, 2-3 pts. wt. of quick lime, 6-9 pts. wt. of microbial inoculant, 10-15 pts. wt. of soil conditioner, and proper amount of water. The soil conditioner: comprises raw materials consisting of 120-140 pts. wt. of diatomite, 30-40 pts. wt. of charcoal, 1-2 pts. wt. of nanocarbon powder, 4-5 pts. wt. of sodium metasilicate, 3-4 pts. wt. of sodium selenite, 4-5 pts. wt. of zinc sulfate, 3-4 pts. wt. of sodium polyacrylate, 0.1-0.14 pts. wt. of cerium-citric acid, 2-3 pts. wt. of manganese sulfate, 6-8 pts. wt. of chitosan, 1-2 pts. wt. of eucalyptus oil, 2-3 pts. wt. of nano jade powder, 1-2 pts. wt. of ammonium persulfate, 2-3 pts. wt. of phytic acid, and proper amount of water; and is prepared by mixing the raw materials except ammonium persulfate with proper amount of water, grinding into slurry, heating at 80-90 degrees C, then adding ammonium persulfate, stirring and reacting for 40-60 minutes, heating and concentrating to paste, preparing into granule, and drying to obtain the product. An INDEPENDENT CLAIM is included for preparing the furfural residue tree fertilizer comprising: crushing the bead tree root and the cotton seed hull after drying, then adding the soybean meal, the furfural residue and microbial inoculant, uniformly stirring, sealing, fermenting at normal temperature for 30-40 days, and stirring one time for every 2-3 days; adding mulberry, tobacco into the fermented material, uniformly stirring, and continuously fermenting under normal temperature for 8-10 days; adding potassium chloride, ferrous sulfate, borax and proper amount of water, stirring to dissolve, introducing the mixture into ammonium sulfate, urea, calcium oxide and zinc gluconate, heating while stirring to completely melt, and spray drying to obtain the mixed powder; and mixing the fermentation material, the mixed powder and other remainder ingredients, uniformly stirring, drying in a drier, and granulating to obtain the product.
