Abstract

The invention discloses a humic acid composition. The humic acid composition is prepared from, by weight, 27.1-39.8 parts of fulvic acid, 1.5-14.2 parts of ulmic acid and 0-7.4 parts of humic acid. A preparation method comprises the steps that grass straw is subjected to prepared material treatment and then subjected to liquid-phase circulating hydrolysis in a mixed solution of potassium hydroxide and anthraquinone to obtain hydrolysate; the hydrolysate is subjected to multiple-effect evaporation and concentration until the solid concentration is 50%-65%, and a concentrated solution is obtained; the concentrated solution is stirred and then subjected to spraying granulation, and the humic acid composition is obtained. According to the preparation method, lignin in the grass straw is decomposed through circulating hydrolysis on the grass straw to obtain the humic acid composition with the very high fulvic acid content. The humic acid composition is reasonable in component proportion and beneficial for increasing the 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...
