为进一步揭示水稻根际土壤特性对CH_4和N_2O排放的影响机理,采用静态暗箱/气相色谱法对晚稻不同品种的CH_4和N_2O排放通量进行了原位观测,并对CH_4和N_2O排放通量与水稻根际土壤特性的相关性进行了分析。结果表明:不同品种CH_4、N_2O季平均排放通量间存在差异,变化范围分别为9.27~14.57 mg/(m~2.h)、7.16~15.28μg/(m~2.h);CH_4排放通量与5 cm处土壤Eh值呈极显著负相关(p

An,one-year field experiment was conducted to measure in situ the greenhouse gases emission fluxes of the late rice cultivars in Hunan double-cropping rice areas and the correlation between the greenhouse gases emission and the characteristics of rice rhizospheric soil was studied to probe the effect of rice rhizospheric soil characteristics on methane and nitrous oxide emission by the method of static opaque chamber / modified gas chromatography.The results showed that the seasonal average emission fluxes of CH4 and N2O were different among ri...
