【摘要】 以耕作和秸秆利用对温室气体排放的影响为重点,简述了当前温室气体排放的研究方法及保护性耕作所产生的温室效应,提出了农田温室气体排放研究方法的主导方向,明确了保护性耕作的温室效应不是免耕与秸秆还田所产生的相对温室效应的简单累加,发展新型保护性耕作技术以及对其温室效应的研究是未来保护性耕作研究的重点。更多还原

【Abstract】 Based on no tillage and straw returned to farmland affecting greenhouse emission, research method about greenhouse emission and greenhouse effect under conservation tillage system were summarized in the paper. The way of research greenhouse emission in future was put forward. It was pointed out that greenhouse effect of conservation tillage was not just simple summation of no tillage’s and straw’s. New type of conservation tillage and its greenhouse effect will be the research focus in the future.更多还原
