USE - Controlled release fertilizer composition used for planting hyacinth (claimed).    ADVANTAGE - The controlled release fertilizer composition ensures improved yield of hyacinth.    DETAILED DESCRIPTION - Controlled release fertilizer composition comprises 50-70 pts. wt. dairy manure, 40-45 pts. wt. pig manure, 70-80 pts. wt. rice straw, 20-30 pts. wt. humus, 15-18 pts. wt. fly ash, 6-8 pts. wt. gelatin, 20-24 pts. wt. charcoal ash, 2-3 pts. wt. biology microbial inoculum, 10-12 pts. wt. quartz sand, 8-10 pts. wt. calcium superphosphate, 10-11 pts. wt. ammonium bicarbonate, 6-8 pts. wt. potassium chloride, 12-15 pts. wt. calcium magnesium phosphate fertilizer, 4-6 pts. wt. ferrous sulfate, 10-12 pts. wt. alkyd resin, 2-3 pts. wt. ethylene glycol, 3-4 pts. wt. sodium dodecyl benzene sulfonate, 5-6 pts. wt. crosslinking agent and balanced amount of water, where the crosslinking agent comprises 2-3 pts. wt. butyl acrylate, 3-5 pts. wt. tributyl citrate, 2-3 pts. wt. colophony powder, 5-7 pts. wt. cucumber flour, 1-2 pts. wt. N,N-methylenebisacrylamide, 4-5 pts. wt. ethyl alcohol, 1-2 pts. wt. shellac and balanced amount of water. The crosslinking agent is prepared by mixing colophony powder, cucumber flour, butyl acrylate, tributyl citrate and N,N-methylenebisacrylamide with aqueous ethyl alcohol solution, and then heated them at 70-90 degrees C. The obtained material is mixed with shellac, and then heated them for 20-30 minutes to obtain the finished product. An INDEPENDENT CLAIM is included for a method for preparing a liquid fertilizer composition, which involves:    (A) crushing dairy manure, pig manure, rice straw, humus, fly ash, gelatin and charcoal ash into 140 meshes size powder, and then adding biological microbial inoculum to the obtained material;    (B) fermenting the obtained material at 38-45 degrees C for 20-22 days;    (C) mixing calcium phosphate, ammonium hydrogen carbonate, potassium chloride, calcium magnesium phosphate fertilizer and ferrous sulfate and water;    (D) heating the obtained material, and then adding alkyd resin, sodium dodecyl benzene sulfonate, ethyl alcohol, crosslinking agent and remaining raw material to the obtained material;    (E) adding crushed quartz sand to the obtained material, and then heating them for 30-40 minutes;    (F) cooling the obtained material naturally, and then crushing them into 20 meshes granule; and    (G) mixing the obtained granules with the obtained fermented material to obtain the finished product.
