摘要
用玻璃罩收集武汉地区早熟中稻田在自然栽培条件下释放的甲烷,并以气相色谱法测定释放甲烷量。实验结果表明,武汉地区早熟中稻田的甲烷释放量从0.10～14.10mg·m^(-2)·h^(-1)。在分蘖末期和幼穗分化始期释放量最大。稻田白天释放的甲烷量比晚上多。
The quantity of methane emanated from paddy field in Hubei province was measured in the prsent study. In general, it was found to range from 0.10～14.10 mg·m^(-2)·h^(-1). The rate of methane emission was higher during daytime than at night and highest at late tillering and panicle initiation stage. In addition, 65% of the emitted methane was emanated into atmosphere via rice plant.
