NOVELTY - Controlled release fertilizer comprises 40-50 pts. wt. wheat straw, 60-65 pts. wt. corn straw, 40-45 pts. wt. carbon slag, 55-70 pts. wt. sheep manure, 20-24 pts. wt. soybean residue, 28-32 pts. wt. fungus dreg, 2-3 pts. wt. biological microbial inoculum, 10-14 pts. wt. zeolite, 8-10 pts. wt. ammonium dihydrogen phosphate, 5-6 pts. wt. zinc sulfate, 5-7 pts. wt. potassium hydroxide, 10-14 pts. wt. potassium chloride, 8-11 pts. wt. ammonium carbonate, 10-12 pts. wt. alkyd resin, 2-3 pts. wt. isopropanol, 3-4 pts. wt. sodium dodecyl benzene sulfonate and 4-5 pts. wt. cross-linking agent.    USE - Controlled release fertilizer used for planting peach tree (claimed).    ADVANTAGE - The controlled release fertilizer is effective and biodegradable, and loosens soil particle and recycles waste.    DETAILED DESCRIPTION - Controlled release fertilizer comprises 40-50 pts. wt. wheat straw, 60-65 pts. wt. corn straw, 40-45 pts. wt. carbon slag, 55-70 pts. wt. sheep manure, 20-24 pts. wt. soybean residue, 28-32 pts. wt. edible fungus dreg, 2-3 pts. wt. biological microbial inoculum, 10-14 pts. wt. zeolite powder, 8-10 pts. wt. ammonium dihydrogen phosphate, 5-6 pts. wt. zinc sulfate, 5-7 pts. wt. potassium hydroxide, 10-14 pts. wt. potassium chloride, 8-11 pts. wt. ammonium carbonate, 10-12 pts. wt. alkyd resin, 2-3 pts. wt. isopropanol, 3-4 pts. wt. sodium dodecyl benzene sulfonate, 4-5 pts. wt. cross-linking agent and balanced amount of water. Cross-linking agent comprises 2-3 pts. wt. butyl acrylate, 3-5 pts. wt. tributyl citrate, 2-3 pts. wt. colophony powder, 5-7 pts. wt. green cucumber flour, 1-2 pts. wt. N,N'-methylenebisacrylamide, 4-5 pts. wt. ethyl alcohol, 1-2 pts. wt. shellac powder and balanced amount of water,a nd prepared by mixing ethyl alcohol and water in 1:3 ratio to obtain solution that is mixed with colophony powder, butyl acrylate, N,N'-methylenebisacrylamide and tributyl citrate at 70-90 degrees C to obtain mixture. The obtained mixture is mixed green cucumber flour and shellac powder to obtain product. An INDEPENDENT CLAIM is included for a method for preparing controlled release fertilizer, which involves:    (A) drying and crushing wheat straw, corn straw, carbon slag, sheep manure, soybean residue and edible fungus dreg to obtain powder;    (B) fermenting obtained powder with biological microbial inoculum for 15-17 days at 38-43 degrees C;    (C) mixing monoammonium phosphate, zinc sulfate, potassium chloride and potassium carbonate with fermented material to obtain another mixture that is heated to obtain melt;    (D) heating alkyd resin, sodium dodecyl benzene sulfonate, isopropanol, cross-linking agent and remaining components to obtain another melt that is cooled to get solid mixture;    (E) crushing solid mixture into granule;    (F) mixing obtained granules, fermented material and melt to obtain another mixture; and    (G) adjusting water content (20%) of mixture to obtain product.
