| 英文摘要 | Specific management of water regimes, soil and N in China might play an important role in regulating N(2)O and CH(4) emissions in rice fields. Nitrous oxide and methane emissions from alternate non-flooded/flooded paddies were monitored simultaneously during a 516-day incubation with lysimeter experiments. Two N sources ((15)N-(NH(4))(2)SO(4) and (15)N-labeled milk vetch) were applied to two contrasting paddies: one derived from Xiashu loess (Loess) and one from Quaternary red clay (Clay). Both N(2)O and CH(4) emissions were significantly higher in soil Clay than in soil Loess during the flooded period. For both soil, N(2)O emissions peaked at the transition periods shortly after the beginning of the flooded and non-flooded seasons. Soil type affected N(2)O emission patterns. In soil Clay, the emission peak during the transition period from non-flooded to flooded conditions was much higher than the peak during the transition period from flooded to non-flooded conditions. In soil Loess, the emission peak during the transition period from flooded to non-flooded conditions was obviously higher than the peak during the transition period from non-flooded to flooded conditions except for milk vetch treatment. Soil type also had a significant effect on CH(4) emissions during the flooded season, over which the weighted average flux was 111 mg C m(-2) h(-1) and 2.2 mg C m(-2) h-(1) from Clay and Loess, respectively. Results indicated that it was the transition in the water regime that dominated N(2)O emissions while it was the soil type that dominated CH(4) emissions during the flooded season. Anaerobic oxidation of methane possibly existed in soil Loess during the flooded season. |
