Abstract

The invention discloses a humic acid composition. The composition comprises the following components in parts by weight: 43.81-62.03 parts of humic acid, 0.54-5.13 parts of hymatomalenic acid, and 0-2.47 parts of pyrotomalenic acid. A preparation method comprises the following steps: material preparation and processing are carried out for straw of graminaceous plants, and liquid phase circulation and hydrolysis are carried out for the straw material in a solution of ammonium sulfite, in order to obtain hydrolysate; multiple-effect evaporation and concentration of the hydrolysate are carried out till the solid concentration is 50-65%, and a concentrated solution is obtained; the concentrated solution is stirred, spray granulation is carried out, in order to obtain the humic acid composition. Circulation and hydrolysis of the straw of graminaceous plants are carried out, lignin in the straw of graminaceous plants is decomposed, and the humic acid composition with a high content of humic acid is obtained. The humic acid composition has reasonable combination of each component, and is good for improving crop yield.

Description

technical field [0001] The invention relates to the field of humic acid, in particular to a humic acid composition and a preparation method of the composition. Background technique [0002] Humic acid (HA), a natural organic polymer compound, is the main component of humic substances. It is a kind of macromolecular organic weak acid mixture formed by a series of decomposition and transformation of animal and plant remains such as lignin under the action of microorganisms, geophysics and chemistry. Humic acid is not a single acid, but a complex mixture containing carboxyl groups, phenolic hydroxyl groups, etc., so the mixture exhibits the properties of dibasic acids or occasionally tribasic acids. Humic acid usually forms complexes with ions in nature. [0003] As an organic raw material, humic acid is widely used in various fields such as agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine, sanitation, and environmental prote...
