| 摘 要： | 稻田土壤是最重要碳库之一,农田管理措施影响着稻田土壤碳排放.本文综合论述了本课题组过去几年的研究成果,并结合国内外其它相关研究,分析和讨论稻田养鸭,灌溉方式、氮肥施用和耕作措施对土壤碳排放的影响.研究指出,稻田养鸭有效降低稻田温室效应,间歇灌溉降低CH4排放,施氮肥不影响土壤碳排放,而免耕有效降低土壤碳排放.由于土壤碳...

| Abstract: | Paddy soil is one of the most important carbon storages,which is affected by agricultural management practices.The achievements obtained in past researches were reviewed and the effects of agricultural management practices on carbon emissions,including the stocking of duck in paddy field,irrigation,N fertilization and tillage,were discussed.The results indicated that raising ducks in paddy field significantly decreased greenhouse effects,intermittent irrigation reduced CH4 emissions,N fertilization did not ... |
