Abstract

The invention relates to the technical field of compound fertilizers, in particular to a traditional Chinese medicine residue biomass charcoal compound fertilizer and a preparation method thereof. The preparation method comprises the following steps: pyrolyzing the traditional Chinese medicine residue at high temperature to obtain traditional Chinese medicine residue biomass charcoal and a combustible gas; mixing the raw material of the compound fertilizer and the traditional Chinese medicine residue biomass charcoal of which the weight is 8-12% that of the gross raw materials of the compound fertilizer, fusing, pelleting, collecting the granular material; cooling the collected granular material at negative pressure and screening; performing capsulation, packaging for delivery to obtain the traditional Chinese medicine residue biomass charcoal compound fertilizer. The Traditional Chinese medicine residue biomass charcoal compound fertilizer provided by the invention is rich in nutrient substances, the release of nutrient elements is coordinated and lasting, the nutrition use efficiency of the compound fertilizer is high, the soil can be effectively improved and fertilized, the utilization rate of the fertilizer is improved, the organic content of the soil is increased, the soil bulk density is reduced, the water and nutrient retention ability of the soil is improved, the crop growth is promoted, the crop yield is obviously improved, the crop quality is improved and obvious economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a traditional Chinese medicine dregs biomass carbon-based compound fertilizer and a preparation method thereof. Background technique [0002] Fertilization has become one of the indispensable technical measures of agricultural production, contributing more than half of crop production. The utilization rate of fertilizers in China has always been relatively low. For example, the average utilization rate of nitrogen fertilizers for current crops is only about 30%, which is nearly 20 percentage points lower than that of developed countries. This is due to the unscientific fertilization methods on the one hand, and the fertilizer itself on the other hand. characteristics. It is urgent to improve fertilizer utilization efficiency, and research and development of new multifunctional fertilizers is one of the important ways to improve fertilizer utilization efficiency. ...
