| 摘 要： | 稻田CH_4排放的季节变化和水稻的生长过程(水稻高度)有较大的关系,有机肥对稻田CH_4排放有促进作用,沼气发酵肥可以降低稻田的CH_4排放量,水稻品种对稻田CH_4排放有一定影响,垄作是减少稻田CH_4排放的一种重要方法。

| Abstract: | Methane emission from rice paddy field had been studied for 5 years in Leshan Sichuan province south - west China. Two emission peaks were found during the whole growing season,and these two peaks have a good relationship with the hight changing rate of the rice plant. Organic fertilizer can increase the methane emission rate. Fermented fertilizer from biogas pits can decrease methane emission rate. Hybrid rice paddy has a lower methane emission rate and a higher plants and a higher yield compared with normal rice paddy.
The average methane emission rate for 5 year is 67. 0 mg/m2. h,which should be regarded as a upper limit. |
