Abstract:

This paper reviewed production, oxidation and transmission of methane in rice paddy fields as affected by the water management, the influence of rice straw incorporation on emission of methane and carbon sequestration in rice paddy fields. Two aspects were put forward which should be strengthened about methane emission from Chinese rice paddy fields in the future: (1) Research on production mechanisms of methane in rice paddy fields; (2) Research on the comprehensive influence of rice straw incorporation on emission of methane and carbon sequestration in rice paddy fields. Some suggestions were as references for us on how to carry out water management and how to incorporate rice straw in rice paddy fields, in order to develop the ecological efficiency of rice paddy fields.
