Abstract

The invention discloses a nutritional type high slow release performance compound fertilizer for planting rice. The nutritional type high slow release performance compound fertilizer comprises the raw materials of urea, monoammonium phosphate, potassium chloride, ammonium chloride, diammonium hydrogen phosphate, monocalcium phosphate, zinc sulfate, ammonium molybdate, magnesium sulfate, oyster shell powder, kieselguhr, modified sepiolite powder, kaolin powder, talcum powder, dolomite powder, zeolite powder, thiourea, dicyandiamide, chicken manure, cicada manure, wormcast, maize straw, rapeseed cake, bagasse, coal ash, perilla seed, humic acid, EM strain, lignin and a modified slow-release inhibitor. The invention further provides a preparation method of the nutritional type high slow release performance compound fertilizer. The prepared compound fertilizer has an excellent slow release performance, provides rich nutrient substances for the crop, promotes the growth of the crop, and improves the yield and the quality of the crop.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a nutrient-type high slow-release compound fertilizer for rice planting and a preparation method thereof. Background technique [0002] 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 one of the important reasons why nitrogen, phosphorus, and potassium cannot be fully utilized by crops is that the existing traditional inorganic fertilizers dissolve too quickly, which accelerates the decomposition of fertilizers by soil microorganisms and accelerates the rate of nutrient degradation. The conversion, volatilization, leaching, and physical and chemical fixation of traditional chemical fertilizers have a utiliz...
