USE - Organic selenium and vitamin A enriched biodegradable coated fertilizer used for strawberry (claimed).    ADVANTAGE - The organic selenium and vitamin A enriched biodegradable coated fertilizer increases quality and stress resistance of strawberry.    DETAILED DESCRIPTION - Organic selenium and vitamin A enriched biodegradable coated fertilizer comprises 54-56 pts. wt. soybean curb residue, 21-24 pts. wt. anhydrous sodium sulfate powder, 1-2 pts. wt. silicic acid, 1-2 pts. wt. choline chloride, 0.2-0.4 pts. wt. vitamin additive, 43-47 pts. wt. selenium-enriched plant residue, 40-45 pts. wt. selenium-enriched edible fungus residue, 2-3 pts. wt. selenomethionine, 18-23 pts. wt. ammonium phosphate, 14-18 pts. wt. potassium chloride, 7-9 pts. wt. carbamide, 16-21 pts. wt. phosphate, 5-9 pts. wt. effective microorganisms, 8-11 pts. wt. modified bamboo fiber, 2-4 pts. wt. nanocarbon, 1-3 pts. wt. zinc sulfate, 0.3-0.5 pts. wt. potassium polyacrylate, 0.3-0.7 pts. wt. sodium selenite, 1-2 pts. wt. boric acid, 0.1-0.4 pts. wt. silane coupling agent KH550 and balanced amount of water. Modified bamboo fiber comprises 5-7 pts. wt. nanodiatomite, 2-4 pts. wt. nanokaoline, 1-3 pts. wt. nano-zinc borate, 67-82 pts. wt. bamboo fiber, 15-19 pts. wt. amino resin, 0.1-0.2 pts. wt. potassium sulfate, 0.02-0.03 pts. wt. ceric ammonium nitrate, 12-14 pts. wt. castor oil and balanced amount of water. Modified bamboo fiber is prepared by mixing and stirring components with water, and then heating at 60 degrees C for 3-4 hours in water bath. The mixture is dried, and then castor oil is mixed, and then ground into fine powder. An INDEPENDENT CLAIM is included for a method for preparing organic selenium and vitamin A enriched biodegradable coated fertilizer used for strawberry, which involves:    (A) mixing uniformly soybean curb residue, anhydrous sodium sulfate powder, selenium-enriched plant waste, selenium-enriched edible fungus residue and effective microorganism microbial inoculum with water;    (B) performing aerobic fermentation of the mixture at high temperature for 10-12 days;    (C) drying the fermented product and crushing through 200-400 meshes, and then adding remaining components; and    (D) granulating the mixture, spraying urea on surface of the product, and then cooling and drying to obtain final product.
