Abstract: The difference of methane transport ability and its reasons were clemonstrated by detecting different rice varieties, which grow in water-nutrient solution cultivation.In the same time, the influence of paddy rice satus on methane transport was demonstrated by controlling the methane transport path. The main results were as follows: with the evolution of Indicia rice varieties, Methane transport rate of plant increased, the root oxidizes increased gradually. In seedling stage, leaves transported 50 percent of methane. Methane transport rate varied with the number of root and the dry weight of root. They were obviously and lineally correlated. The number of stems and tillers of plant affected methane transport rate. In a certain range, the more the stems and tillers, the higher methane transport rate. These results indicate that root oxidizes mostly cause difference of methane transport rate in rice varieties. Healthy plant, more leaves, root system upgrowth, more stem and tiller cause more methane transport rate.
