Abstract

The invention discloses coated slow-release fertilizer for paddy rice and a preparation method thereof. The coated slow-release fertilizer comprises a fertilizer matrix and a coating agent coating theouter surface of the fertilizer matrix, wherein the fertilizer matrix comprises nitrapyrin crystal urea, oxalyl urea, potassium-magnesium sulfate fertilizer, potassium dihydrogen phosphate, potassiumchloride, calcium chloride, sodium selenite, borate, molybdate, manganese sulfate, zinc ammonium phosphate, iron ammonium phosphate, magnesium ammonium phosphate, rapeseed meal, sunflower seed meal,tea seed meal, xylitol residues, edible fungus residues, shrimp shell powder, seaweed powder, potassium fulvate, rooting powder, naphthalene acetic acid, potassium citrate, chitosan and plant extraction agent; the coating agent comprises oxidized starch, glycerin, sodium alginate, urea-formaldehyde resin, cotton fibers, phosphoric acid, sodium lactate, acrylic urethane and clay. The coated slow-release fertilizer for paddy rice is high in fertilizer efficiency, lasting in effect, capable of effectively increasing the yield of the paddy rice and capable of improving the quality of the paddy rice.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a coated slow-release fertilizer for rice. Background technique [0002] Rice is an important food crop in my country, which has the characteristics of wide planting area and large demand. Since our country has a large population base and less arable land per capita, increasing rice production is of great significance to the daily life of residents and our country's grain reserves. At present, there are still unreasonable ingredients in rice fertilizers. The release rate of nutrients in fertilizers is inconsistent with the law of rice fertilizer requirements. The output of rice reduces the quality of rice, which is not conducive to the sustainable development of my country's agriculture. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a coated slow-release fertili...
