Abstract

The process of producing organic fertilizer includes the following steps: heating water as liquid reaction medium; adding lignite or leonardite, gluconic acid, tartaric acid, alkyl malionic acid, glutaric acid and EDTA; adding sodium hydroxide for further extracting reaction; adding hydrogen peroxide for oxidation reaction; adding citric acid and inorganic salts of the inorganic trace elements into the liquid extract for chelating reaction; regulating the pH value to neutrality; and drying to obtain organic fertilizer. The present invention has the following advantages: complete humic substance components, high product stability, high trace element utilizing rate, reduced total use amount, high safety and high absorption rate.

Description

technical field [0001] The invention relates to a production process of an organic fertilizer. Background technique [0002] At present, the synthetic micro-fertilizers in the fertilizer market have a low utilization rate, and the use of the current humic acid micro-fertilizers has the problem of inconsistent and inconspicuous beneficial effects on crops. . Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned weak point, a kind of production technology of organic fertilizer is provided. [0004] The technical scheme of the present invention is that a production process of organic fertilizer is carried out according to the following steps, adding lignite or weathered lignite and organic chelating reactants: gluconic acid, tartaric acid into the liquid reaction medium water heated to 80°C-100°C , hydroxymalonic acid, glutaric acid, EDTA or their salts, the weight ratio of lignite and water is 1:5-10, lignite and gluconic ac...
