生物炭因结构和理化性质独特、原材料丰富及应用前景广阔等特点，在农业及环境污染治理等领域的应用较为广泛。基于相关文献，综述了农业废弃物基生物炭在改善土壤理化性质、提高土壤养分、改善土壤微生态环境、促进作物生长、修复污染土壤及缓解连作障碍等方面的效应，旨在为农业废弃物基生物炭在农业生产中的应用提供参考。

Biochar has been widely used in agriculture and environmental pollution improvement due to its unique structure, physical and chemical properties, abundant raw materials and broad application prospects. In this paper, the application effects of agricultural waste biochar on improving soil physical and chemical properties, enhancing soil nutrients, improving soil micro-ecological environment, promoting crop growth, recovering polluted soil, and relieving continuous cropping obstacles were reviewed. The future application prospects were also expected, aiming to provide reference for application and extension of agricultural waste biochar in agriculture.
