Abstract

The invention relates to a method for activating humic acid through physical and chemical combined solid-phase ball milling. The method comprises the following steps: firstly, smashing the weathered coal containing inactivated humic acid and filtering through a 60-mesh sieve, thereby acquiring powdered weathered coal A; adding a solid activating agent B and a synergist C into the weathered coal A and uniformly mixing; putting A, B and C into a ball mill; and setting a rotating speed at 60-80rpm and ball-milling for 60min-90min, thereby acquiring an activated product rich in humic acid. Compared with the traditional chemical activating method, the method has the advantages that more than 50% of energy consumption is saved and no dust or harmful gas is discharged; under the effect of the synergist, the humic acid with a micro-molecule structure is easily generated; the stimulation effect on crops and the improving effect on soil are further benefited; and the method is a low-cost, high-efficiency and environment-friendly activating method.

Description

[0001] (1) Technical field

[0002] The invention relates to a method for activating humic acid by combining physical and chemical solid-phase ball milling, and belongs to the field of agricultural resource recycling.

[0003] (2) Background technology

[0004] Humic acid is a complex mixture colloid composed of natural polymeric hydroxycarboxylic acids, and its basic structural units are condensed aromatic rings and aliphatic groups. Humic acid mainly exists in soil and water as well as lignite. However, the percentage content of humic acid in soil and water is very low, and the main source of humic acid in industry is peat and lignite. Humic acid can promote the ability of crops to absorb water and nutrients, improve the utilization rate of fertilizer nutrients, enhance crop resistance, improve crop quality and improve the physical and chemical properties of soil, etc.
