NOVELTY - Granular fertilizer is prepared by utilizing 65-70 pts. wt. bagasse, 70-80 pts. wt. phosphoric acid, 75-90 pts. wt. alcohol, 80-100 pts. wt. straw powder, 3-5 pts. wt. agar, 15-20 pts. wt. humic acid, 20-25 pts. wt. earthworm soil, 5-7 pts. wt. effective microorganism microbial inoculum, 20-25 pts. wt. potassium oxide, 10-20 pts. wt. nicotine water, 8-10 pts. wt. ferrous sulfate monohydrate, 20-30 pts. wt. zinc sulfate, 7-9 pts. wt. binder and balanced amount of water. Binder comprises 2-4 pts. wt. hexamethylenetetramine, 3-6 pts. wt. castor oil and 4-5 pts. wt. alumina powder.    USE - Granular fertilizer.    DETAILED DESCRIPTION - Granular fertilizer is prepared by utilizing 65-70 pts. wt. bagasse, 70-80 pts. wt. phosphoric acid, 75-90 pts. wt. alcohol, 80-100 pts. wt. straw powder, 3-5 pts. wt. agar, 15-20 pts. wt. humic acid, 20-25 pts. wt. earthworm soil, 5-7 pts. wt. effective microorganism microbial inoculum, 20-25 pts. wt. potassium oxide, 10-20 pts. wt. nicotine water, 8-10 pts. wt. ferrous sulfate monohydrate, 20-30 pts. wt. zinc sulfate, 7-9 pts. wt. binder and balanced amount of water. Binder comprises 2-4 pts. wt. hexamethylenetetramine, 3-6 pts. wt. castor oil, 4-5 pts. wt. alumina powder, 12-16 pts. wt. polyoxyethylene ether, 0.5-1 pts. wt. wood powder, 5-8 pts. wt. rosin powder, 12-15 pts. wt. ethyl alcohol and 60 pts. wt. water. Binder is prepared by mixing rosin powder with ethyl alcohol in a reaction kettle and then 1/3 of water is added to dissolve at 80-100 for 20-30 minutes. Polyoxyethylene ether, castor oil and water are added in the reaction kettle, and remaining components are added and stirred for 30-40 minutes to form emulsion. An INDEPENDENT CLAIM is included for a method for preparing granular fertilizer, which involves:    (A) crushing bagasse and soaking with water (2-3 times) for 4-6 hours;    (B) ball-milling product for 30-40 minutes and performing the extrusion of powder;    (C) soaking water (2-3 times) in phosphoric acid for 4.5 hours, and filtering, adding alcohol solvent with stirring, and centrifuging to obtain precipitate;    (D) drying precipitate and adding binder, crushing to obtain powder with particle diameter of 2-3 mm;    (E) carbonizing the product at 600-700 degrees C for 4-5 hours; and    (F) adding remaining components with product, and then granulating and spray drying.
