Abstract

The invention relates to a humic acid liquid fertilizer which is prepared by the following components in parts by weight: 10-20 parts of fulvic acid potassium, 35-45 parts of major elements, 10-15 parts of trace elements, 1.0-1.5 parts of cosolvent, 0.2-0.4 part of stabilizer, 0.3-0.5 part of permeation promoter, 0.8-1.5 parts of natural surfactant, 1.0-2.0 parts of anti-adversity promoter, 0.06-0.1 part of growth promoter and 25-33 parts of water. The humic acid liquid fertilizer has the advantages of simple process, stable micellar system, uniform and balanced nutrients, scientific components and a variety of effects of significantly improving the utilization rate of the fertilizer, promoting the growth of crops, increasing the anti-adversity, improving the yield and quality of the crops and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and relates to a humic acid liquid fertilizer, in particular to a stable and efficient multifunctional humic acid liquid fertilizer. Background technique [0002] The role of chemical fertilizers in increasing crop production has become increasingly prominent. Statistics from the World Food and Agriculture Organization (FAO) show that 40%-60% of the world's food production in the 20th century came from the contribution of fertilizers. However, with the acceleration of urbanization, the area and quality of arable land are declining, and the population is growing rapidly. The per capita arable land in the world is 0.4 hectares, while the per capita arable land area in my country is only 0.1 hectares. The issue of food security has become a worldwide issue. The role of existing conventional fertilizers in agricultural production is undeniable, the utilization rate is not high, the ...
