中文摘要：
探讨了水稻栽培方式对稻田甲烷排放的影响。在福州平原稻田设置了4种水稻栽培方式，即手插、抛秧、机插和直播。采用静态箱法对甲烷排放进行了测定，水稻产量特征的测定采用收获法。在整个观测期内，4种水稻栽培方式稻田甲烷排放平均值分别为3．65，3．66，4．47和4．63mg／（m2·h），甲烷平均排放由小到大的顺序分别为抛秧〈手插〈直播〈机插。从水稻千粒重观察，4种栽培方式由小到大的排序为机插〈手插〈直播〈抛秧；从单丛产量观察，4种栽培方式由小到大的排序为手插〈抛秧〈机插〈直播。
英文摘要：
Rice is the main cereal crop, and the need is increasing with the population increment. Paddy fields are the key sour~＇e of methane, and it＇ s very important to cooperate tile rice production and the methane emission. For the reason, our study discussed tile effe（＇t of cultivation patterns on paddy fiehls me.thane emissions, setting up four kinds of rice cuhivation patterns, hand transplanting, seedlings throwing, machine transplanting and dire（＇t seeding, methane emissions and rice pro（tu（＇tion characters were determined by chamber and harvest methods in the Fuzhou plain. During the whole observation period, different rice euhivation patterns of methane emissions averaged values were 3.65, 3.66 , 4.47 and 4.63 rag/（ m~ ~ h）, which were folluwed the order of seedlings throwing 〈 hand transplanting 〈 direct seeding 〈 machine transplanting. Seen f＇rom tile grain, the four different cultivation patterns were machine transplanting 〈 hand transplanting 〈 direct seeding 〈 seedlings throwing and seen from single bundle yield, the flmr different （＇ultivation patterns were hand transplanting 〈 seedlings throwing 〈 machine transplanting 〈 direct seeding.
