摘要：Biochar, a late-model environmental functional material, has been widely applied in environmental remediation, agricultural production, and energy utilization due to its excellent characteristics such as porosity and high specific surface area. In recent years, many studies on the effects of biochar on agricultural soil and crop quality have been performed. The application of biochar can influence soil microbial status directly or indirectly by changing the physicochemical properties of soil. Apart from increasing soil pH, biochar can also increase soil organic matter and nutrient elements, which ultimately affect crop yield and quality. This review summarizes and overviews the recent research advances on the influence of biochar application on soil microbial community diversity, microbial ecological functions, soil enzymes and their functional genes, and on crop quality and yield from the perspective of soil microorganisms. This review provides guidance and references for further research into biochar applications.
