DETAILED DESCRIPTION - Coated fertilizer comprises 18-25 pts. wt. bagasse mortar, 30-34 pts. wt. sludge, 24-28 pts. wt. common Cnidium fruit, 18-21 pts. wt. thunder god vine, 16-20 pts. wt. radix sophorae flavescentis, 4-6 pts. wt. molasses, 1-2 pts. wt. Borax (RTM: Sodium borate), 0.5-0.8 pts. wt. copper sulfate, 5-8 pts. wt. montmorillonite, 0.4-7 pts. wt. zinc borate, 13-15 pts. wt. potassium dihydrogen phosphate, 18-21 pts. wt. ammonium sulfate, 0.4-7 pts. wt. ammonium molybdate, 8-11 pts. wt. soil modifying agent, 5-8 pts. wt. effective microorganisms, 6-10 pts. wt. polyether polyhydric alcohols and balanced amount of water. 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, 0.4-8 pts. wt. gelatin, 1-2 pts. wt. dimethyl glycol dimethacrylate, 6-9 pts. wt. chitin and soap stone powder (9-13). Soil modifying agent is prepared by mixing peat. The mixed peat is dried, and then crushed. The crushed material is mixed with magnesium sulfate, calcium chloride, ferrous sulfate, selenium yeast, manganese sulfate, sodium montmorillonite and soap stone powder uniformly. Lentinan, polyaspartic acid, humic acid and dimethyl dimethacrylate are added to the mixed material, and then ground. Gibberellin, cytokinin, gelatin and paclobutrazol are added to the obtained material, and then mixed uniformly. The obtained material is granulated in a granulator, and then mixed with chitosan uniformly at normal temperature. The obtained granules are cooled, and then dried to obtain the desired product. An INDEPENDENT CLAIM is included for a method for preparing coated fertilizer, which involves:    (A) drying common Cnidium fruit and thunder god vine;    (B) distilling radix sophorae flavescentis with anhydrous ethyl alcohol (75%);    (C) separating liquid slag;    (D) evaporating the obtained liquid on a water bath to obtain active substance;    (E) mixing medicinal slag, bagasse slurry, sludge, molasses and effective microorganism inoculum uniformly;    (F) fermenting the obtained mixture for 23-29 days;    (G) drying the obtained fermented mixture;    (H) adding Borax, active substance, copper sulfate, zinc borate, ammonium molybdate, montmorillonite, potassium dihydrogen phosphate and ammonium sulfate to the obtained material;    (I) mixing the obtained material;    (J) grinding and dispersing the mixed material uniformly;    (K) adding the obtained material into a granulator;    (L) adding the obtained material into a fluidization bed coating machine at 70-100 degrees C;    (M) spraying polyether polyhydric alcohols on the obtained granules into the fluidization bed;    (N) adding soil improving agent to the obtained granules;    (O) mixing the obtained mixture uniformly;    (P) cooling the obtained material; and    (Q) drying the obtained material to obtain the desired product.
