【摘要】：從生物炭和污泥的基本理化性質(zhì)出發(fā),介紹了生物炭和污泥對農(nóng)作物增產(chǎn)、改良土壤等方面的作用機制,概述了生物炭和污泥耦合肥料的制備、國內(nèi)外還田技術(shù)的研究現(xiàn)狀以及污泥—生物炭耦合農(nóng)用的效用情況。通過對污泥—生物炭肥料品質(zhì)的全面分析,針對性評價了其安全性、穩(wěn)定性及增產(chǎn)效果,認(rèn)為該技術(shù)擁有較強的推廣可行性。我國農(nóng)村秸稈資源大量剩余,城市污泥過剩引發(fā)環(huán)境問題,而污泥—生物炭耦合生態(tài)農(nóng)用技術(shù)為秸稈和污泥的資源化、無害化處理利用提供了解決方案。
[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.
