稻田甲烷代谢及其对电子受体的响应

Reviews on methane metabolism and response to electron acceptor in paddy fields

稻田是主要的甲烷排放源之一,其代谢过程及减排策略研究日益受到关注。本文综述了稻田甲烷代谢及其对电子受体响应的最新研究进展。结果表明,稻田甲烷代谢过程因环境条件的改变具有明显的变异性;电子受体主要是通过对甲烷产生和氧化的综合影响,最终控制着土壤甲烷排放;施肥和水分管理均会调节电子受体对甲烷代谢过程的影响。

Paddy fields represent one of the main methane flux source,and the study of metabolism and reduction strategy are the focus.Methane metabolism and response to electron acceptor in paddy fields are reviewed.The results showed that paddy fields methane metabolism is significantly variability as the environmental factors alteration.Electron acceptor control methane emission in soil through affecting methane production and oxidation.Both fertilization and water management adjust the efficiency of electron acceptor on methane metabolism.
