| 摘 要： | 以山东省桓台县高产农田为试验对象，分析在高产条件下，不同秸秆还田模式和氮肥施用量对农田CO2排放的影响。结果表明，氮肥施用量与秸秆还田模式都是影响土壤CO2排放的重要因素，玉米秸秆和小麦秸秆全部还田的处理土壤CO2排放通量高于其它中低氮处理，而小麦秸秆还田与不还田的各处理间差别不大。麦秸还田配施高氮处理的CO2排放通量普遍高于其它处理。

| Abstract: | Huantai County was famous for its crop straw retum and high fertilizer input. The experiment was carried out for studying the effect of straw - return and nitrogen application on the CO2 emission in high - yield - farmland. The resuits indicated that different straw return and nitrogen application were two important factors to effect the CO2 emissions of soil. The CO2 emission of wheat - and - maize - straw - return treatment was higher than all of the other treatments and wheat - straw- return plus high level N fertilizer application showed the same result. |

| Keywords: | high- yield -farmland straw -return nitrogen fertilizer CO2 emission |
