摘  要:
在应对全球气候变暖和保障粮食安全的双重背景下,如何增加土壤碳库容量、提升土壤生产力以及减少环境危害已成为农学家、土壤学家和环境学家在二十一世纪的研究重点和热点,黑碳(或生物碳)在农田土壤中的应用作为一种增加土壤碳库和提高土地生产力的新方法引起了极大关注。本文综述了黑碳在农业土壤中的含量,应用黑碳(生物碳)对作物产量、土壤肥力和温室气体排放的影响;探讨了应用黑碳影响作物生产力和土壤环境行为的机理以及农田土壤应用黑碳在不同区域、作物类型、用量和黑碳性质上的差异表现;展望了农田应用黑碳未来研究的方向和热点。

摘  要:
Sequestration carbon in soils with CO2 mitigation and enhancing global food security has been a significant research hot topic under circumstance of global warming and food demand pressure.Biochar application in arable soils becomes a vigor method for increasing C pool and improving soil productivity,which arouse interests for scientists all over the world recently.The contents of black carbon in soils and the effects of biochar application on crop productivity and soil fertility as well as greenhouse gas emission in arable soils are reviewed.The possible mechanism of biochar application on crop yield productivity and soil-envrionment aspects is discussed,and the discussion is focused on practical performance of biochar application in different regions,crop varieties,fertilization amounts and biochar types.Several key research points in agriculture and perspectives in future are proposed.
