摘　　要：从生物炭和污泥的基本理化性质出发,介绍了生物炭和污泥对农作物增产、改良土壤等方面的作用机制,概述了生物炭和污泥耦合肥料的制备、国内外还田技术的研究现状以及污泥—生物炭耦合农用的效用情况。通过对污泥—生物炭肥料品质的全面分析,针对性评价了其安全性、稳定性及增产效果,认为该技术拥有较强的推广可行性。我国农村秸秆资源大量剩余,城市污泥过剩引发环境问题,而污泥—生物炭耦合生态农用技术为秸秆和污泥的资源化、无害化处理利用提供了解决方案。Based on the basic physical and chemical properties of sludge and biochar,the function mechanism of sludge and biochar in improving crop production and soil improvement were reviewed. The preparation, current research situation,and application of coupling fertilizer with sludge and biochar were summarized. The safety, stability, and yield-increasing effect of the fertilizer were evaluated by the comprehensive analy- sis of the fertilizer＇s quality. It was feasible to popularize the fertilizer in China. Lots of rural straw re- sources are wasted in China, excess sludge caused urban environmental problems, the solution to solve the problems will be the application of sludge-biochar fertilizer, which will successfully make the straw and sludge recovery and harmless.
