Embodiment 1

[0049] (1) Take sesame stalks, castor stalks, peanut stalks, cotton stalks, and soybean stalks, and crush them to obtain grass slices with a length of 60 mm. Wash the grass slices to remove sediment and dehydrate until the dry matter content is greater than 15%. , add screw feeder to compress and continue to dehydrate to obtain oil crop straw raw material with absolute dry matter content of 35-45%;

[0050] (2) The raw material of oil crop straw, the mixed solution of potassium hydroxide and anthraquinone, and the stock solution A are mixed and then continuously added to the reactor, while the stock solution B is continuously circulated at 175°C. The amount of potassium hydroxide is the absolute dry matter of the raw material of oil crop straw 22% of the mass, the amount of anthraquinone is 0.06% of the absolute dry matter of the oil crop straw raw material, the consumption of the mixed solution of potassium hydroxide and anthraquinone+stock solution A+circulating stock solutio...

Abstract

The invention discloses a humic acid composition. The composition comprises the following components in parts by weight: 24.3-36.5 parts of humic acid, 8.6-13.8 parts of hymatomalenic acid, and 1.2-3.2 parts of pyrotomalenic acid. A preparation method comprises the following steps: material preparation and processing are carried out for straw of oil crops, and liquid phase circulation and hydrolysis are carried out for the straw material in a mixed solution of potassium hydroxide and anthraquinone 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 oil crops are carried out, lignin in the straw of oil crops 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...
