The increase of a methane concentration in atmosphere which may affect global changes has received great attention in recent years. Paddy field was recognized as one of the main biogenic sources. Current wet culture of rice in favor of methane production and emission was investigated by many scientists. Soil methane concentration increased significantly 20 days after flooding. The maximum rate of methane production appeared at 40 days after flooding. About 95% of emission methane took the routes via rice plants. The heading and flowering stage had the highest amount of emission methane contributing to the atmosphere. In this paper, the factors affecting methane production in and emission from flooded soils, and how to reduce them were discussed.
