为控制农田温室气体排放的途径提供据,通过实验室培养的方法测定了不同水分管理条件下CH4和N2O的排放,干旱处理(60%~70%WFP)和长期淹水土样在施肥后的Eh变化.最终得出:稻田CH4和N2O排放之间存在着互为消长的关系(R2=0.609), CH4和N2O的排放是水肥共同作用的结果,水分管理通过Eh来影响气体排放,有机质是造成前后期排放浓度差异的主要.

Nitrous oxide and methane were measured in the different water management conditions with laboratory culture methods, Eh change of soil samples after fertilization of the drought treatment ( 60%~70% WFP) was monitored. The results showed that there was the trade-off relationship between the emission of CH4 and N2O (R2=0.609) , and emission of CH4 and N2O was the results of the interaction of water and fertilizer, and gas emissions were affected by water management through Eh. Therefore, it was discovered that organic matter was the main reason contributed to the difference of emission concentration early and later period.
