Abstract

The invention relates to the technical field of a calcium magnesium phosphate fertilizer, in particular to a bamboo biomass charcoal based calcium magnesium phosphate fertilizer and a preparation method thereof. The preparation method comprises the following steps of carrying out high temperature pyrolyzing to bamboos to obtain bamboo-based biomass charcoal and combustible gas; melting, pelletizing and collecting particles after a raw material of the calcium magnesium phosphate fertilizer and 20-24% of biomass charcoal based on the total weight of the raw materials of the calcium magnesium phosphate fertilizer are mixed; cooling the collected particles with negative pressure, and screening; enveloping the screened particles, and packaging to ship, so as to obtain the bamboo biomass charcoal based calcium magnesium phosphate fertilizer. The bamboo biomass charcoal based calcium magnesium phosphate fertilizer provided by the invention is abundant in nutrient, the nutrient elements can be released and coordinated for a long time, the use ratio of the fertilizer nutrients is high, the soil can be effectively improved and fertilized, the use ratio of the fertilizer can be improved, the organic content of the soil can be improved, the soil bulk density can be reduced, the capacity of preserving moisture and fertility of the soil can be improved, the growth of the crops can be promoted, the yield of crops can be significantly improved, the crop quality can be improved, and the significant economic benefit can be realized.

Description

technical field [0001] The invention relates to the technical field of calcium magnesium phosphate fertilizer, in particular to a bamboo biomass charcoal-based calcium magnesium phosphate 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 effi...
