摘要
秸秆还田可促进农作物增产,但同时会造成农田温室气体排放增加。通过田间试验,研究不同秸秆还田量与施氮量下稻田CH4的排放规律,探讨在保证水稻产量的前提下有效减少稻田CH4排放的施肥方式,为我国农田温室气体减排研究提供资料。
Straw returning can promote the yield increasing of crops; meanwhile it can cause the growth of greenhouse gas emission in farmlands. In the article, it studied the emission rule of CH4 in different amount of returning straw and nitrogen fertilizer in rice field,and on the basis of assuring rice yield, it discussed the way of fertilizer application which can effectively reduce the emission of CH4,provided related data for the research of greenhouse gas emission reduction in farmland in China.
