| 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 return and high fertilizer input.The experiment was carried out for studying the effect of straw-return and nitrogen application on the CO-2 emission in high-yield-farmland.The results indicated that different straw return and nitrogen application were two important factors to effect the CO-2 emissions of soil.The CO-2 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. |
