Humic acid composition and application thereof

Abstract

The invention relates to the field of fertilizer, in particular to a humic acid composition and application thereof. The humic acid composition is prepared from fulvic acid, ulmic acid and humic acid, wherein the amount of total humic acid in the humic acid composition is 30-60 parts by weight, and the mass ratio of fulvic acid to ulmic acid is (2-4):1. Experiments show that components of the humic acid composition are reasonable in proportioning and can promote one another, improve the fertilizer efficiency, help one another and complement one another, so that the nutrient releasing speed of the humic acid composition and the nutrient absorbing rule of crops have the high synchronicity; the humic acid composition can directly supply organic energy to soil microorganisms, promote breeding of the microorganisms by improving the plant nutrient and the root soil environment of the crops and delay the decay rate of the soil microorganisms, therefore, the soil microorganisms can keep vigorous vital activities for a long term, and then growth and development of the crops are promoted.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a humic acid composition and its application. Background technique [0002] Humic acid (HA), also known as humic acid, is a natural organic polymer compound and 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, phenolic hydroxyl and other functional groups, so the mixture exhibits the properties of dibasic acid or occasionally tribasic acid. 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 envi...
