| ABSTRACT |
| The characteristics of methane emission were compared among six types of upland and paddy soils developed from different parent materials with distinct physical and chemical properties after planting rice. The fluxes of methane emission in submerged soils from the upland were obviously lower than those from the paddy rice field. The flux of methane emission in the paddy soil developed from fluvo-aquic soil was the largest among all the types of soils. Planting of rice was helpful to emission of methane in soils. The amounts of various groups of methanogenic flora were conformed with the differences among the fluxes of methane emission in various types of soils. Methane formation was observed in each type of air-dried soils stored for a long time after addition of water and incubation at 35℃. |
