USE - Fertilizer used for regulating strawberry plant diseases and insect pests (claimed).    ADVANTAGE - The fertilizer ensures water retention property, looses soil, and improves soil quality, and has improved inhibitory effect on some bacteria.    DETAILED DESCRIPTION - Fertilizer comprises 16-24 pts. wt. ammonium sulfate, 1-2 pts. wt. potassium sulfate, 7-9 pts. wt. ammonium bicarbonate, 22-28 pts. wt. expanded soybean, 0.2-0.4 pts. wt. fungus, 26-29 pts. wt. rapeseed cake, 18-24 pts. wt. beer, 6-8 pts. wt. molasses, 15-19 pts. wt. potassium sulfate, 17-23 pts. wt. phosphorus pentoxide, 20-25 pts. wt. dry duck manure, 12-14 pts. wt. corn powder, 32-38 pts. wt. rabbit manure, 6-9 pts. wt. effective microorganism microbial inoculum, 11-13 pts. wt. modified bamboo fiber, 2-4 pts. wt. polyvinyl alcohol, 3-4 pts. wt. diatomite, 2-3 pts. wt. nanometer carbon, 1-2 pts. wt. zinc sulfate, 3-5 pts. wt. itaconic acid, 1-2 pts. wt. dimethyltin oxide, 0.2-0.4 pts. wt. acrylate, 0.6-1.2 pts. wt. sorbitan monostearate, 0.1-0.3 pts. wt. ammonium persulfate and balanced amount of water. Modified bamboo fiber comprises 2-4 pts. wt. nanometer calcium carbonate, 3-5 pts. wt. nanometer iron ore tailing residue, 6-8 pts. wt. nano attapulgite, 73-80 pts. wt. bamboo fiber, 18-23 pts. wt. acrylic acid, 0.2-0.4 pts. wt. ammonium persulfate, 0.02-0.03 pts. wt. N,N'-methylenebisacrylamide, 12-14 pts. wt. tung oil and balanced amount of water. Modified bamboo fiber is prepared by mixing nano calcium carbonate, nano iron ore tailing residue, nano attapulgite and bamboo fiber in a reaction container. Water is added in the reaction container, stirred the mixture, and then remaining components are added. The mixture is heated and stirred in a water bath at 70 degrees C for 3-4 hours and dried. The dried product is mixed and stirred with tung oil, and then ground into fine powder. An INDEPENDENT CLAIM is included for a method for preparing fertilizer, which involves:    (A) mixing puffing soybean, fungus, rapeseed cake, beer, molasses, dry duck manure, corn powder, dry rabbit manure and microbial inoculums;    (B) keeping water content as 43-46% in the mixture, and then performing aerobic fermentation at high temperature for 15-20 days;    (C) processing in a granulator to obtain granules;    (D) dissolving sorbitan monostearate with water, and adding diatomite with speed of 1000-1200 revolutions per minute to form suspension;    (E) mixing zinc sulfate, nano-carbon, polyvinyl alcohol and modified bamboo fiber, and then grinding and dispersing uniformly to form adhesive coating;    (F) mixing itaconic acid and dimethyltin oxide, and then adding remaining components at 70 degrees C; and    (G) heating the mixture at 98 degrees C for 30 minutes, cooling it, and then granulating in the granulator into granules.
