Abstract

The invention discloses a slow release fertilizer used for rice planting. The fertilizer is prepared from urea, monoammonium phosphate, potassium chloride, ammonium chloride, diammonium phosphate, calcium triple superphosphate, zinc sulfate, ammonium molybdate, ammonium nitrate complex, gamma-polyglutamic acid, attapulgite, modified sepiolite powder, kaolin powder, talcum powder, stannous chloride, sodium bisulfite, boric acid, oxalic acid, cow dung, soybean meal, furfural residues, corn straw, rape-seed cakes, bagasse, fly ash, medical stone, humic acid, EM strain, hydroxymethyl cellulose and modified sustained-release preparation. The invention further provides a preparing method of the slow release fertilizer used for rice planting. The slow release fertilizer used for rice planting has excellent slow release performance, can provide rich nutrient substances, promote the growth of the rice, increase the yield of the rice, and improve the quality of the rice.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a slow-release fertilizer for rice planting and a preparation method thereof. Background technique [0002] Rice is the most important grain rice in China. Fertilization of rice is an extremely complicated issue, which needs to be based on the nutritional characteristics of rice varieties, the properties of fertilizers, soil, climate and other characteristics. [0003] At present, chemical fertilizers are widely used in a large amount and have become one of the most important means of production in agricultural production, accounting for a large share of agricultural industry costs. A large number of long-term scientific researches have shown that the utilization rate of fertilizers is low, and an important reason why nitrogen, phosphorus, and potassium cannot be fully utilized by rice is that the existing traditional inorganic fertilizers dissolve too quickly, which accelerates the de...
