Abstract

The invention discloses a preparation method of a humic acid water soluble fertilizer, and belongs to the technical field of an agricultural fertilizer. Firstly, through weighing, all raw material ingredients are proportionally weighed; then, premixed materials are stirred to obtain uniform premixed materials; next, the pH of the premixed materials is regulated; next, base materials capable of carrying humic acid are prepared; next, the humic acid is added to obtain a soil aggregate structure; finally, premixed materials and soil aggregate structures are mixed to obtain a finished product. Theinvention provides the preparation method of the humic acid water soluble fertilizer. The preparation method has the advantages that base materials can be formed; the humic acid is attached onto thesoil aggregate structure, so that the active ingredients of the humic acid can continuously and stably achieve the effects.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a method for preparing humic acid water-soluble fertilizers. Background technique [0002] Humic acid is a high-molecular organic substance produced by the decomposition and transformation of animal and plant remains by microorganisms. It can promote the formation of soil aggregate structure, enhance soil permeability, and fertilizer retention. It has a stimulating effect on plant growth, increases plant drought resistance, cold resistance, Disease resistance, is an ideal ecological fertilizer. [0003] The most widely used humic acid fertilizer is sodium humate, but sodium humate is very soluble in water, and it will be seriously lost with rainwater when it is used. Therefore, how to improve the utilization rate of fertilizers, increase yields, be environmentally friendly, and improve soil is of great significance to the sustainable development of China's agric...
