【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。
[Abstract]:Based on the physical and chemical properties of biochar and sludge, the mechanism of biochar and sludge on increasing crop yield and improving soil was introduced, and the preparation of biochar and sludge coupling fertilizer was summarized. The research status of returning technology and the effect of sludge-biochar coupling agriculture at home and abroad. Based on the comprehensive analysis of the quality of sludge and biochar fertilizer, the safety, stability and effect of increasing production were evaluated, and it was concluded that the technology was feasible to be popularized. A large amount of surplus straw resources in rural areas of China, urban sludge surplus caused environmental problems, while the sludge biochar coupling ecological agricultural technology for straw and sludge recycling, harmless treatment and utilization of the solution.
