不同母质发育的水稻土中铁、锰对甲烷排放的影响

Effects of Fe and Mn in Paddy Soils Derived from Different Parent Materials on Methane Emission.

盆栽结果表明，不同土壤类型铁、锰含量的差异是造成不同土壤类型间甲烷排放量差异甚大的重要因素之一。土壤中铁、锰通过对土壤氧化还原电位及根膜形成的影响而影响甲烷的排放。

The results of pot experiments showed that the difference of Fe and Mn contents in diffe rent paddy soils was one of the most important factors which made the differences of methane emission amounts of different soils. It has been found that the effects of soil Fe and Mn on soil methane emission were caused by affecting soil Eh and root plate.
