秸秆还田对水稻生长发育和稻田温室气体排放的影响

摘要

秸秆是一种传统的能源物质，营养丰富，秸秆还田可培肥地力，增加作物产量。本文综述了秸秆及其制成的有机物料还田对水稻产量和稻米品质的影响及其生物学机制、秸秆还田对培肥土壤的作用和稻田温室气体排放的影响，讨论了秸秆还田存在的问题和今后研究的重点。%Straw as a kind of traditional energy material is rich in nutrition. Straw returning could increase soil fertilization and crop yields. This review summarized the effects of straw and organic materials made by straw returning on grain yield and quality of rice and their biological mechanism, and soil fertility and greenhouse gas emission from paddy field. The existing problems and further studies on straw returning were discussed.
