| 摘 要： | 通过田间试验,采用静态箱-气相色谱法测定CO2排放通量,研究臭氧(O3)浓度升高对土壤-冬小麦系统CO2排放的影响.结果表明,O3浓度升高对CO2排放的季节变化模式无明显影响.在返青期和拔节孕穗期,O3浓度升高显著降低了土壤-冬小麦系统的CO2排放通量;在抽穗成熟期,O3浓度100 nL·L-1处理对CO2排放通量没有...

| Abstract: | To investigate the impact of elevated ozone(O3) on CO2 emission from soil-winter wheat system,outdoor experiments with simulating elevated O3 concentration were conducted,and static dark chamber-gas chromatograph method was used to measure CO2 emission fluxes.Results indicated that the elevated O3 did not change the seasonal pattern of CO2 emissions from soil-winter wheat system,but significantly decreased CO2 emission fluxes during turning-green stage and elongation-pregnant stage.From heading to maturity,... |
