Abstract:

Methane (CH₄) and nitrous oxide (N₂O) are the significant sources of greenhouse gas in the paddy field and irrigated lowland rice production systems. The different water-saving irrigation management is one of the most important practices, which may affect methane (CH₄) and nitrous oxide (N₂O) emissions from paddy fields. A two-year field experiment at Jiutai county of Changchun city in the Northeast China was designed to study the effects of alternate wetting and drying irrigation I and II (AWD I and II) on CH₄ and N₂O emissions and agronomic performances, with continuous flood irrigation (CF) as the control. The traits for grain yield and yield components, biomass production in rice, methane (CH₄) and nitrous oxide (N₂O) emissions from paddy fields were investigated in our experiments in two years. The results showed that different irrigations affected greatly grain yield and biomass production. Grain yield and biomass production was highest under CF, and followed by under AWD I and under AWD II in both years. For methane (CH₄) and nitrous oxide (N₂O) emissions from paddy fields, there were significant differences on three different irrigations in two years. In the CH₄, fluxes from paddy field was greatest under CF condition and followed by under AWD I and under AWD II in two years. Meanwhile, in the N₂O, fluxes from paddy field was lowest under CF condition and  highest under AWD II in both years. These results indicated that greenhouse gases from rice paddy field were significantly affected by irrigation method. Considering both of higher grain yield and the reasonable greenhouse gas emission from rice paddy field, AWD I was strongly recommended for rice paddy field in Northeast China.
