2、對(duì)水稻產(chǎn)量的影響53討論與小結(jié)5參考文獻(xiàn)7致謝通過(guò)優(yōu)化栽培技術(shù)協(xié)同實(shí)現(xiàn)高產(chǎn)和溫室氣體減排是發(fā)展低碳稻作技術(shù)的關(guān)鍵。本文在構(gòu)建不同栽培技術(shù)模式（高產(chǎn)拋栽模式、高產(chǎn)移栽模式和農(nóng)戶模式）的基礎(chǔ)上，監(jiān)測(cè)了不同栽培模式下早稻產(chǎn)量及稻出甲烷和氧化亞氮排放的差異。結(jié)果表明：高產(chǎn)拋栽模式和高產(chǎn)移栽模式水稻產(chǎn)量均顯著高于農(nóng)戶模式，增產(chǎn)幅度分別達(dá)到16.4%和17.7%,而高產(chǎn)拋栽模式和高產(chǎn)移栽模式產(chǎn)量Z間差異不顯著，冇效穗數(shù)的捉高是獲得高產(chǎn)的關(guān)鍵。高產(chǎn)拋栽模式全生育期甲烷排放顯著低于高產(chǎn)移栽模式和農(nóng)戶模式，而高產(chǎn)移栽模式和農(nóng)戶模式之間差異不顯著。高產(chǎn)拋栽模式溫室氣體排放強(qiáng)度最低，農(nóng)戶模式最高，高產(chǎn)移栽模式居屮
