摘要
稻田生态系统中存在着好氧微域,其中同时发生甲烷氧化和铵氧化。甲烷和铵氧化过程具有极为相似的微生物机理。稻田土壤中的甲烷可能影响铵氧化过程;施用铵态氮肥对甲烷的氧化也有强烈影响。本文对稻田土壤中甲烷氧化与铵氧化关系做一简要综述。
Rice paddy soil has oxic-anoxic interfaces where methane consumption and ammonia oxidation might happen simultaneously.Due to similarity of enzyme-catalyzing methane consumption to ammonia oxidation,methane produced within paddy soil could affect ammonia oxidation while methane oxidation will probably be significantly influenced by variation of ammonia concentration induced by the application of ammonia-based fertilizers.The relationship of methane consumption to ammonia oxidation in rice paddy soils is reviewed here.
