Abstract
大氣甲烷濃度之逐漸增加，可能危及全球氣候變遷，已受到嚴重之關切。水田被認為生物性產生甲烷之主要場所之一，其現行栽培管理方式，有利於甲烷之產生與逸釋，引起科學家之研究。
土壤甲烷濃度於旱田浸水後20天顯著增加，最大的甲烷產生速率出現於浸水後40天。植稻水田之甲烷約有95％經由稻株逸釋大氣，最大逸釋率出現於水稻之抽穗開花期。
本文檢討土壤甲烷產生之因素及逸釋途徑，並擬議其控制大氣甲烷濃度之方
法。
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.
