Problems solved by technology

[0008] Taking the above patent as an example, the long ammoniation period of humic acid alone is likely to cause nitrogen damage and pollute the air. Due to the limitation of ammoniation temperature, it is not conducive to production in winter, which makes production restricted and cannot be continuously produced.

Abstract

The invention relates to humic acid compound fertilizer and a preparation method thereof. The raw materials of the compound fertilizer comprise the following components: potassium chloride, monoammonium phosphate, urea, danty or lignite, sulfuric acid, wash water and liquid ammonia. By adoption of the method, the danty or lignite can be ammoniated along with the production through improvement and index control on an amino acid pelleting process. By adoption of the method, timely ammoniation and timely use are realized, activity reduction after ammoniation caused by overlong storage time of during traditional ammoniation is avoided, and the limitation of the traditional method is solved.

Description

technical field [0001] The invention relates to a humic acid fertilizer, in particular to a humic acid compound fertilizer and a preparation method thereof. Background technique [0002] Humic acid (HA for short), also known as: black humic acid, humic acid, humic acid, is the remains of animals and plants, mainly plant remains, after microbial decomposition and transformation, and a series of geochemical A class of organic matter created and accumulated by processes. It is a heterogeneous polymer condensation polymer, and can also be regarded as an amorphous polymer colloid. It has good physiological activity and functions of absorption, complexation, exchange, etc., and plays a role in improving soil structure. [0003] Humic acid has a wide range of uses, and has been used in various aspects such as industry, agriculture, medicine, and environmental protection. In terms of fertilizer utilization, there were reports in foreign countries that combined humic acid and urea t...
