| 摘 要： | 以汕优63和安选6号2个水稻品种(组合)为材料,研究了氮肥施用量和节水栽培对稻田甲烷排放量的影响.结果表明:随着氮肥施用量的增加,甲烷排放量也增加,不同氮肥水平之间的甲烷总排放量和移栽后40、50、60、70天之间的平均排放量在0.01水平上有差异.节水栽培比正常灌溉条件下甲烷排放量大幅度减少.

| Abstract: | Shanyou 63 and Anxuan No 6 were used as material and the experiment was designed in four nitrogenous fertilizer level disposal.In this paper the effect of different nitrogenous fertilizer level on the release of methane were analyzed.The results showed: with the increasing of nitrogenous fertilizer level,the release of methane was increasing;the total release of methane and the average release of methane of 40～70 d had dominant diversity at different levels.Therefore,in rice production,nitrogenous fertilizer should be reduced at the base of a certain production.Less-water-cultivation not only reduced water consumption and warm-house-effection but also protected the environment. |
