The invention provides a special slow-release fertilizer for paddy rice. The special slow-release fertilizer for paddy rice comprises the following raw material components in parts by weight: 20-30 parts of composted cow manure, 4-6 parts of silkworm pupa powder, 10-20 parts of sunflower faceplate, 10-12 parts of egg shell powder, 40-50 parts of potassium dihydrogen phosphate, 20-30 parts of calcium superphosphate, 60-80 parts of plant ash, 30-40 parts of ammonium chloride, 8-10 parts of sodium silicate, 8-10 parts of urea, 0.1-0.2 part of ferrous sulfate, 0.1-0.2 part of zinc gluconate, 0.0001-0.0003 part of S-abscisic acid, 2-3 parts of borax, 0.01-0.02 part of copper sulfate, 6-8 parts of acrylic acid, 3-4 parts of sodium hydroxide, 2-3 parts of acrylamide, 10-15 parts of hydroxypropyl distarch phosphate, 1-2 parts of ammonium persulfate, 8-10 parts of triethanolamine, 4-6 parts of waste plastic powder, an appropriate amount of water and 10-15 parts of fertilizer additives. The special slow-release fertilizer for paddy rice, provided by the invention, has reasonable mixture ratio of nutrients, and can slowly release the nutrients by fertilizing once, keep slow release of fertilizer efficiency, ensure nitrogen-phosphorus-potassium nutrients during the whole growth process of the paddy rice, realize convenience in use, and simultaneously improve the drought resistance, high and low temperature resistance and pest and disease resistance of the paddy rice.
