USE - As fermented fertilizer for sweet-scented Osmanthus (claimed).    DETAILED DESCRIPTION - Fermented fertilizer comprises 8-10 pts. wt. rice straw, 12-15 pts. wt. duckweed, 8-9 pts. wt. silica gel powder, 2-3 pts. wt. carrageenan, 9-10 pts. wt. peat, 5-6 pts. wt. limestone powder, 12-14 pts. wt. peanut meal, 2-3 pts. wt. effective microorganism (EM), 8-10 pts. wt. ammonium chloride, 4-5 pts. wt. oxalic acid, 6-8 pts. wt. diammonium phosphate, 4-6 pts. wt. calcium superphosphate, 9-10 pts. wt. potassium sulfate, 4-5 pts. wt. auxiliary agent and suitable amount of water. The auxiliary agent comprises 4-6 pts. wt. polyethylene glycol, 2-4 pts. wt. 1,3-benzenedicarbonyl dichloride, 3-5 pts. wt. sodium nitrophenolate, 10-12 pts. wt. phosphorus residue, 6-8 pts. wt. nitro humic acid, 3-4 pts. wt. hydrated potassium aluminum sulfate, 1-2 pts. wt. alpha lipoic acid, 2-3 pts. wt. n-butanol and suitable amount of water. The auxiliary agent is prepared by (a) sieving phosphorus residue through a sieve of 200 mesh sieve, and adding nitro humic acid to the powder, (b) mixing polyethylene glycol with n-butanol in ratio of 1:10, dissolving mixture using water, adding 1,3-benzenedicarbonyl dichloride, sodium nitrophenolate, hydrated potassium aluminum sulfate and alpha lipoic acid, heating the mixture and stirring the heated mixture for 1-2 hours until the components gets dissolved, and (c) mixing the powder and product obtained in step (b), drying the mixture, and pulverizing dried mixture. An INDEPENDENT CLAIM is included for method for preparing the fertilizer which involves (a) mixing rice straw, duckweed, peat, limestone powder and peanut meal, adding EM to the mixture in ratio of 1:10, adding water to the mixture, stirring the mixture until moisture content of the mixture reaches 30%, crushing the stirred mixture, fermenting the crushed mixture at 35-38 degrees C for 15-18 days, and stirring the mixture once in every 3 days, (b) mixing ammonium chloride, oxalic acid, diammonium phosphate, calcium superphosphate, and potassium sulfate, adding 4 times water to the mixture, and heating the mixture by stirring, (c) adding silica gel powder to the above-mentioned mixture, adding water to the mixture in ratio of 1:100, stirring the mixture under normal temperature for 20-30 minutes to obtain gel, and (d) mixing the product obtained in step (a) with the gel for 8-10 minutes using a rolling machine, drying the mixture until moisture content of the mixture reaches not greater than 18%, ultrafine crushing the dried mixture, granulating the crushed mixture to obtain granules of particle size of 3-6 mm, and packing the granules in a bag.
