Abstract

The invention discloses a humic acid compound fertilizer which is prepared from humic acid, amino acid, potassium oxide, sodium fluosilicate, urea, activated organic matter, nutrients, potassium sulfate, calcium powder, a microbial agent, a powdery anti-caking agent, ammonium phosphate, an oxidizing agent and potassium hydroxide. The invention further discloses a preparation method of the humic acid compound fertilizer. The preparation method comprises the steps of selecting weathered coal, preparing humic acid, mixing to obtain mixed humic acid, drying to obtain the humic acid compound fertilizer and the like. According to the humic acid compound fertilizer and the preparation method thereof, the problems of soil hardening, poor air permeability and the like can be solved, crop growth canbe promoted, and the crop yield is increased.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer production, in particular to a humic acid compound fertilizer and a preparation method thereof. Background technique [0002] Humic acid is a natural organic polymer compound. It exists in the humus of soil and the substance of low-rank coal. According to the growth process, there are primary humic acid and regenerated humic acid. The part of humic acid soluble in acetone, ethanol and other solutions is called brown humic acid or oxalic acid; the part soluble in water is called fulvic acid. Contains elements such as carbon, hydrogen, oxygen, nitrogen, and active groups such as hydroxyl, carboxyl, carbonyl, quinone, and methoxy. These active groups determine that humic acid has properties such as weak acidity, hydrophilicity, ion exchange, complexation, redox and physiological activity. Formed by partial decomposition of plant residues in the presence of air and moisture. Humic aci...
