USE - Controlled release fertilizer used for planting towel gourd plant (claimed).    ADVANTAGE - The controlled release fertilizer increases quality, yield and seedling survival rate of towel gourd and prevents from cold freeze injury.    DETAILED DESCRIPTION - Controlled release fertilizer comprises 60-70 pts. wt. humus soil, 50-55 pts. wt. sawdust, 20-25 pts. wt. dry tree leaves, 40-50 pts. wt. soybean cake, 35-40 pts. wt. sugar, 55-70 pts. wt. waste paper, 2-3 pts. wt. microbial inoculum, 10-12 pts. wt. quartz sand, 5-6 pts. wt. zinc sulfate heptahydrate, 8-10 pts. wt. ammonium chloride, 6-7 pts. wt. sodium phosphate, 7-9 pts. wt. potassium nitrate, 3-4 pts. wt. ferrous sulfate, 9-12 pts. wt. urea, 8-12 pts. wt. alkyd resin, 2-3 pts. wt. alkyd resin, 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 wood powder, 1-2 pts. wt. N,N'-methylenebisacrylamide, 4-5 pts. wt. ethyl alcohol, 1-2 pts. wt. shellac powder and balanced amount of water, and is prepared by dissolving rosin powder, butyl acrylate, N,N'-methylenebisacrylamide and tributyl citrate in hydro-ethanolic solution at 70-90 degrees C to obtain a solution that is mixed shellac powder, remaining ingredients and water to obtain mixture. The obtained mixture is heated for 20-30 minutes to obtain cross-linking agent. An INDEPENDENT CLAIM is included for a method for preparing controlled release fertilizer, which involves:    (A) drying and crushing humus soil, saw dust, dry tree leaves, soybean cake, sugar residue and waste paper to obtain powder;    (B) adding microbial inoculum with water in obtained powder to obtain a mixture;    (C) fermenting mixture at 42-45 degrees C for 20-24 days;    (D) stirring heptahydrate zinc sulfate, ammonium chloride, sodium phosphate, potassium nitrate, ferrous sulfate, urea and water to obtain a solution;    (E) adding alkyd resin, sodium dodecyl benzene sulfonate, glycol, cross-linking agent and remaining component to obtain another mixture;    (F) heating mixture for 10-15 minutes;    (G) cooling obtained mixture to obtain solid material;    (H) crushing solid material to obtain resin granule; and    (I) mixing fermented material and resin granule to obtain product.
