| 摘 要： | 为比较不同水稻品种间甲烷和氧化亚氮排放的差异,采用圆柱体静止箱取样、气相色谱分析,测定了不同早、晚稻品种在不同生育期甲烷和氧化亚氮的排放通量,考察其与水稻植株特性的相关性.结果表明,早稻甲烷、氧化亚氮排放通量分别在抽穗期、孕穗期出现峰值;晚稻甲烷、氧化亚氮排放通最分别在拔节期、乳熟期出现峰值.不同水稻品种间甲烷和氧化亚...

| Abstract: | To probe the mechanism of differences in CH4 and N2O emission among rice cultivars,this pot experiment was conduced to measure CH4 and N2O emission fluxes and plant characteristics of rice cultivars by static closed chamber method and gas chromatograph technique.The results showed that the maximum values of CH4 and N2O emission appeared at the heading stage and the booting stage respectively for the early rice.For the late rice,the maximum values of CH4 and N2O emission appeared at the shooting stage and th... |
