| 摘 要： | 采用静态箱法测定了常规耕作、免耕留低茬低覆盖、免耕留高茬低覆盖、免耕留低茬高覆盖和免耕留高茬高覆盖5个处理条件下燕麦播种前、生育过程中和收割后土壤CO2、CH4和N2O的排放通量.结果表明:CO2排放通量呈单峰曲线变化,峰值出现在苗期;CH4排放通量多为负值,表现为"吸收",季节性变化不明显;N2O排放规律性不明显.处...

| Abstract: | Greenhouse gas emissions(CO2,CH4 and N2O) under 5 treatments,including conventional tillage,no-tillage with low stubble and low mulch,no-tillage with high stubble and low mulch,no-tillage with low stubble and high mulch,and no-tillage with high stubble and high mulch,were determined using static gas cases on oat production field before seed sowing,during growth,and after harvest.The results showed: CO2 emission fluxes followed a single peak curve,and the peak appeared at the seedling stage.CH4 fluxes were m... |
