Problems solved by technology

[0003] The present invention aims at the difficulty of decomposing cellulose substances in the existing potash fertilizer preparation process, hindering the release and mineralization of cell contents, secondary pollution easily caused by impurities entering the soil, poor binding force on heavy metal pollution, and poor soil safety, etc. Insufficient, a preparation method of green potassium fertilizer for carbon sequestration and emission reduction is proposed. Through this preparation method, the deficiencies in the prior art can be solved, and the raw materials are diversified, which is beneficial to capture the carbon element in the soil and realize the long-term supply of potassium source. Meet the requirements of green agriculture

Abstract

The invention relates to a preparation method for a carbon fixation and emission reduction green potassium fertilizer, and belongs to the technical field of fertilizer preparation. The preparation ofthe potassium fertilizer is completed by preparing a biochar material and preparing, fermenting, drying and pulverizing a biochar composite material, and the preparation principle is clear; compared with a traditional potassium fertilizer preparation method, the method is diversified in raw materials, provides convenience for capturing carbon elements in the soil, achieves long-term supply of potassium sources, and meets the requirements of green agriculture.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and relates to a preparation method of a potash fertilizer, in particular to a preparation method of a green potash fertilizer for carbon sequestration and emission reduction. Background technique [0002] With the specialization, industrialization and large-scale development of agricultural production in my country, the requirements of agriculture for fertilizers and soil fertility have been continuously upgraded, and the extensive use of traditional inorganic fertilizers has led to the deterioration of soil physical and chemical properties, and the yield, quality and resistance of agricultural products. decline, restricting the sustainable development of agricultural planting. In view of the above problems, many agricultural farmers choose to use organic fertilizers to improve planting conditions, but the key step in the preparation of organic fertilizers is the decomposition of r...
