Abstract

The invention relates to the technical field of soil conditioners, in particular to a straw biomass charcoal based soil conditioner and a preparation method thereof. The preparation method includes the steps: splitting straws at high temperature to obtain straw biomass charcoal and combustible gas; mixing, melting and pelletizing raw materials of the soil conditioner and the straw biomass charcoal accounting for 16-20% of the weight of the gross raw materials of the soil conditioner, and collecting pellets; cooling the collected pellets by negative pressure and screening the pellets; coating, packaging and delivering the screened pellets to obtain the straw biomass charcoal based soil conditioner. The straw biomass charcoal based soil conditioner has rich nutrient substances, nutrient elements are coordinately and persistently released, fertilizer nutrient utilization efficiency is high, soil can be effectively improved and fertilized, fertilizer utilization rate is increased, the content of soil organic matters is increased, soil bulk density is reduced, the moisture and fertilizer retention capacity of the soil is improved, crop growth is promoted, crop yield can be remarkably improved, crop quality is improved, and the soil conditioner has obvious economic benefits.

Description

technical field [0001] The invention relates to the technical field of soil conditioners, in particular to a straw biomass charcoal-based soil conditioner 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 solid product...
