摘要：
The effects of rice-duck complex ecosystem on methane emission were investigated through two experimental approaches of plot and field experiments in subtropical region of China. Compared with conventional rice fields, the rice-duck ecological planting and breeding model significantly decreased the methane emission from paddy fields. Methane emission flux from rice-duck complex ecosystem presented distinct diurnal and seasonal variations. The diurnal variation in methane emission flux was basically consistent with daily temperature change, and ...
