Methane emission fluxes from double-cropping paddy fields with different combined application of organic and inorganic fertilizers were measured by using the static chamber-gas chromatograph technique during rice growth period in 2012. Results showed that methane emitted principally at the seedling and filleting stages of rice in the durative water logging condition, accounting for 78% of the total methane discharge during the whole rice growth period. It indicated that field moisture content was an significant factor affecting methane emission...
