摘要
In an incubation experiment with flooded rice soil fertilized with different N amounts and sampled at different rice stages, the methane (CH4) and carbon dioxide (CO2) production in relation to soil labile carbon (C) pools under two temperature (35 degrees C and 45 degrees C) and moisture (aerobic and submerged) regimes were investigated. The field treatments imposed in the wet season included unfertilized control and 40, 80 and 120kgha(-1)N fertilization. The production of CH4 was significantly higher (27%) under submerged compared to aerobic conditions, whereas CO2 production was significantly increased under aerobic by 21% compared to submerged conditions. The average labile C pools were significantly increased by 21% at the highest dose of N (120kgha(-1)) compared to control and was found highest at rice panicle initiation stage. But the grain yield had significantly responded only up to 80kgha(-1)N, although soil labile C as well as gaseous C emission was noticed to be highest at 120kgha(-1)N. Hence, 80kgN ha(-1) is a better option in the wet season at low land tropical flooded rice in eastern India for sustaining grain yield and minimizing potential emission of CO2 and CH4.
