USE - Coated fertilizer used for promoting flowering of blueberry in early stage.    ADVANTAGE - The coated fertilizer is eco-friendly, applied during growing period of blueberry, packed in bag that ensures slow release of the coated fertilizer and avoids burning of blueberry seedling, and improves utilization rate of fertlizer. The coated fertilizer has balanced amount of phosphate and potassium, and ensures reduced requirement of dosage of nitrogen fertilizer.    DETAILED DESCRIPTION - Coated fertilizer comprises 0.01-0.03 pts. wt. Rhizobium root, 0.01-0.02 pts. wt. Azotobacter chroococcum, 0.01-0.03 pts. wt. Bacillus megatherium, 34-37 pts. wt. Phellodendron, 30-34 pts. wt. rapeseed cake, 45-50 pts. wt. alfalfa, 0.5-1.0 pts. wt. borax, 3-5 pts. wt. bentonite, 7-11 pts. wt. sodium humate, 14-18 pts. wt. monoammonium phosphate, 8-12 pts. wt. potassium sulfate, 0.3-0.8 pts. wt. castor oil, 8-13 pts. wt. hydroxypropyl methylcellulose, 2-4 pts. wt. gypsum, 7-9 pts. wt. effective microorganism inoculum and 9-12 pts. wt. soil modifying agent. The soil modifying agent comprises 1-2 pts. wt. lentinan, 30-38 pts. wt. peat, 0.5-1.0 pts. wt. polyaspartic acid, 0.5-0.7 pts. wt. magnesium sulfate, 0.1-0.2 pts. wt. calcium chloride, 0.6-0.8 pts. wt. ferrous sulfate, 0.1-0.2 pts. wt. selenium yeast, 0.5-0.7 pts. wt. manganese sulfate, 0.5-0.8 pts. wt. sodium, 0.01-0.02 pts. wt. gibberellin, 0.04-0.06 pts. wt. cytokinin, 0.06-0.08 pts. wt. paclobutrazol, 2-3 pts. wt. humic acid, 0.4-0.8 pts. wt. gelatin, 1-2 pts. wt. ethylene glycol dimethyl ether, 2-4 pts. wt. chitin and 9-13 pts. wt. smectite powder. The soil modifying agent is prepared by drying and crushing magnesium sulfate, calcium chloride, ferrous sulfate, selenium yeast, manganese sulfate, sodium and smectite powder, and then mixed and stirred uniformly with peat to obtain a mixture. The mixture is mixed uniformly with remaining material, and then ground to obtain granules. The granules are dried at normal temperature and cooled to obtain the soil modifying agent. An INDEPENDENT CLAIM is included for a method for preparing coated fertilizer, which involves:    (A) mixing uniformly soybean, rapeseed, alfalfa hay and effective microorganism inoculum with 43-46% water, and then stirring uniformly and sealing through normal process without oxygen supplying system;    (B) performing fermentation for 23-29 days and then drying and crushing through 200-400 meshes to obtain powder;    (C) adding uniformly remaining components except soil modifying agent and cellulose in the powder, and then grinding and dispersing them in a granulator to obtain granules;    (D) mixing hydroxypropyl methylcellulose with water to obtain aqueous solution of hydroxypropyl methylcellulose (5%), and then coating it on the surface of granules by spraying aqueous solution of hydroxypropyl methylcellulose (5%) by using a fluidized-bed coating machine at 70-100 degrees C to obtain coated granules with uniform coating; and    (E) adding components of soil modifying agent and mixing them uniformly, spraying soil modifying agent solution on the coated granules at normal temperature, and then cooling to obtain a final product.
