The invention discloses a high-activity coated fertilizer for strawberries. The fertilizer is prepared from the following raw materials in parts by weight: 22-25 parts of peanut straws, 30-32 parts of castor meal, 25-29 parts of rapeseed meal, 18-25 parts of canal mud, 20-23 parts of diammonium phosphate, 17-24 parts of potassium sulfate, 2-4 parts of calcium persulfate, 18-24 parts of citric acid waste residues, 0.4-0.8 part of molybdenum oxide, 0.4-0.8 part of glycerol monostearate, 1-2 parts of gelatin, 0.02-0.1 part of paclobutrazol, 0.3-0.6 part of biological bacteria, 4-6 parts of perlite, 1-3 parts of rare earth micro-fertilizer, 0.4-1.0 part of camphor oil, 8-14 parts of urea, 6-8 parts of an EM microbicide, 8-11 parts of a soil conditioner and a proper amount of water. According to the high-activity coated fertilizer, chemical fertilizer residues and non-decomposable substances in soil can be efficiently and completely decomposed, the quantity of soil aggregate structures is increased, the moisture and fertility are preserved, pathogenic bacteria in the soil also can be killed, no soil-borne diseases are ensured, the soil is conditioned, the fertility is improved, the nutrient content is high, and crops can grow in a good environment, so that the yield and quality of the crops are ensured; the added rare earth micro-fertilizer can promote the photosynthesis of the crops, improve nitrogen and phosphorus absorption and enhance the stress resistance of the crops. The fertilizer has the effects of remarkably increasing the input-output ratio and increasing the economic benefit.
