Humic acid dual-effect double-chelation multifunctional water-soluble fertilizer and manufacturing method thereof

Abstract

The invention discloses a humic acid dual-effect double-chelation multifunctional water-soluble fertilizer and a manufacturing method thereof. The product is prepared by mixing humic acid powder, sodium hydroxide, silica powder, limestone powder, rare earth, calcium magnesium phosphorus powder, urea powder, magnesium kalium powder, boric acid (or borax), calcium oxide, zinc sulfate, ammonium molybdate, manganese sulfate, copper sulfate, ferrous sulfate and plant source Chinese herbal medicine (alums, nicotine, onions, sophora flavescens lectin, pyrethrin and a cedrela sinensis water extract) with compound sodium nitrophenolate, pimacol, PDLA, an ion chelating agent, a nonionic wetting agent and the like. The manufacturing method of the humic acid dual-effect double-chelation multifunctional water-soluble fertilizer comprises the steps that raw material powder is ground into 200-400-mesh water soluble powder and conveyed into a reaction kettle after being mixed, two-time chelation reactions are performed to generate a humic acid microelement chelate to be dried, compound sodium nitrophenolate, pimacol and the nonionic wetting agent are added and mixed, the product with the water solubility being 99.9% is produced, and packaging and delivery are performed after test qualification.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a humic acid double-effect double-chelating multifunctional water-soluble fertilizer and a preparation method thereof. Background technique [0002] The rapid development of water-saving agriculture will lead to major changes in fertilization methods, fertilization facilities, fertilizer types, and fertilizer structures. Water-soluble fertilizers just meet the requirements of water-saving agriculture for this new type of fertilizer. At present, in my country's agricultural production and planting fertilizers, there have been unfavorable conditions such as the single application of nitrogen, phosphorus, and potassium fertilizers for a long time, the combined application of trace element fertilizers in short supply, and the disconnection of chemical fertilizers and pesticides in the field, which has led to my country's agricultural production. The utilization rate of fertilizers for pla...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in a series of background technologies such as high cost, heavy pollution, serious soil-borne diseases and insect pests, low fertilizer utilization rate, and difficulty in increasing farmers' income caused by the simple application of chemical fertilizer products in agricultural production and planting in my country. Developed and produced a comprehensive nutrient element, balanced fertilizer supply, integrated fertilizer and medicine, to activate the residual fertilizer in the soil, improve the utilization rate of chemical fertilizer, solidify and utilize nitrogen in the air, ecologically prevent and control diseases and insect pests, improve crop resistance, and save planting costs , to improve the yield and quality of crops, increase the income of farmers multi-functional green slow-controlled release fertilizer double-effect water-soluble fertilizer products
