Abstract

The invention relates to the technical field of compound fertilizer, in particular to garden waste biomass charcoal-based compound fertilizer and a preparation method thereof. The preparation method includes steps that cracking garden waste under a high temperature to obtain garden waste biomass charcoal and combustible gas; mixing raw material of the compound fertilizer with 8-12% of garden waste biomass charcoal according to the total raw material weight of the compound fertilizer, melting, granulating and gathering granules; cooling the gathered granules under negative pressure, and sieving; enveloping the sieved granules, packaging and delivering to obtain the garden waste biomass charcoal-based compound fertilizer. The garden waste biomass charcoal-based compound fertilizer is rich in nutrient substance, coordinating and durable in nutrient element release, high in fertilizer nutrient use efficiency, capable of effectively improving and fertilizing the soil, improving the fertilizer utilization rate, increasing the organic substance content of the soil, lowering the volume weight of the soil, improving the moisture and fertility preserving ability of the soil and accelerating the crop growth, and also capable of obviously improving the crop output and improving the crop quality.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a garden waste 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. [0003] Biochar is a so...
