DETAILED DESCRIPTION - Organic fertilizer comprises 15-18 pts. wt. wheat bran, 6-8 pts. wt. Chinese herbal medicinal residue, 22-26 pts. wt. peat soil, 18-20 pts. wt. rapeseed meal, 8-10 pts. wt. aquatic plants, 0.08-0.15 pt. wt. fermentation agent, 0.5-0.8 pt. wt. calcium superphosphate, 3-5 pts. wt. ammonium bicarbonate, 2-3 pts. wt. zeolite powder, 4 pts. wt. borax, 0.5-1.5 pt. wt. zinc chloride, 0.2-0.3 pt. wt. ammonium phosphate, 0.5-0.8 pt. wt. calcium powder, 2-3 pts. wt. potassium sulfate, 0.4-0.6 pt. wt. auxiliary agent and suitable amount of water. The fermentation agent comprises Bacillus licheniformis and Acidithiobacillus thiooxidans in ratio of 1:1, and the auxiliary agent includes 1-2 pts. wt. 2,2-dimethyl-propionic acid ethyl ester, 0.2-0.5 pt. wt. sodium carboxymethyl cellulose, 0.3-0.8 pt. wt. epichlorohydrin, 2-3 pts. wt. dimethicone, 10-12 pts. wt. nanocarbon, 0.8-1.2 pts. wt. diethylaminoethanol, 13-16 pts. wt. plant ash, 1.5-2 pts. wt. ammonium chloride, and suitable amount of water. The auxiliary agent is prepared by dissolving diethylaminoethanol by adding 1-2 times water, adding 2,2-dimethyl-propionic acid ethyl ester, sodium carboxymethyl cellulose, epichlorohydrin, dimethicone, and ammonium chloride, heating the mixture at 60-80 degrees C for 10-15 minutes, dissolving nanocarbon and plant ash, adding the dissolved nanocarbon and plant ash to the heated mixture, stirring the mixture to obtain a paste, drying the stirred paste and crushing the dried mixture. An INDEPENDENT CLAIM is included for method for preparing the fertilizer which involves (a) mixing Chinese herbal medicinal residue, wheat bran and aquatic plants, boiling the mixture by adding 1-2 times water for 2-30 minutes, filtering water from the boiled mixture, adding peat soil and rapeseed meal to the filtered mixture, (b) diluting fermentation agent with 1.1 times water, fermenting the mixture at 38-45 degrees C for 8-10 days, (c) mixing calcium superphosphate, ammonium bicarbonate, zeolite powder, borax, zinc chloride, monoammonium phosphate, calcium powder, potassium sulfate, additives and remaining ingredients, adding 10-15 times water to the mixture, carrying out ultrasonication of mixture by applying acoustic intensity of 0.4-0.8 w/cm2 for 30-40 minutes to obtain crude fertilizer, and (d) spraying a diluent onto crude fertilizer, mechanically stirring the mixture, drying the stirred mixture until moisture content reaches not greater than 20%, sieving the dried mixture through a 200 mesh sieve, ultrafine grinding the sieved mixture, granulating the ground mixture, and packing fertilizer granules.
