1、膜下小苗移栽對(duì)烤煙生長(zhǎng)發(fā)育及產(chǎn)質(zhì)量的影響李建芬李麗華馬君紅董昆樂(lè)苗圃葉紅朝趙世民江凱王煒洛陽(yáng)市煙草公司汝陽(yáng)縣分公司河南省煙草公司洛陽(yáng)市公司［目的］研究膜下小苗移栽對(duì)烤煙生長(zhǎng)發(fā)育及產(chǎn)質(zhì)量的影響。［方法］開(kāi)展不同移栽期膜下小苗移栽與常規(guī)移栽對(duì)比試驗(yàn)，記載分析各小區(qū)煙株生長(zhǎng)發(fā)育和產(chǎn)質(zhì)指標(biāo)。［結(jié)果］4月25日膜下小苗移栽提高了煙株移栽成活率，花葉病相對(duì)防效提高了60.95%，黑脛病相對(duì)防效提高了51.61%;增強(qiáng)了田間長(zhǎng)勢(shì)和抗病性，大田牛.育期縮短，終采期提前，能有效避開(kāi)大田后期的低溫多雨;膜下小苗移栽方式能減少煙葉煙堿和對(duì)煙葉質(zhì)量不利的氯
2、離子含量，提高煙葉鉀含量，有利于煙葉化學(xué)成分的協(xié)調(diào)和內(nèi)在品質(zhì)的提高;在產(chǎn)量與品質(zhì)方面，4月25口移栽的烤煙均價(jià)和產(chǎn)值最高，經(jīng)濟(jì)性狀表現(xiàn)出明顯的優(yōu)勢(shì)。移栽苗齡較小的處理T1移栽成活率有所降低，各經(jīng)濟(jì)性狀略低于CK，說(shuō)明小苗移栽盡管有利于生育期提前，能避開(kāi)前期干旱和后期低溫冷害的影響，但不是越早越好。［結(jié)論］豫丙煙區(qū)4月25日膜下小苗移栽較為適宜。關(guān)鍵詞：小苗;膜下移栽;烤煙;生長(zhǎng)發(fā)育;產(chǎn)質(zhì)量;基金：洛陽(yáng)市煙草公司科技計(jì)劃項(xiàng)目(LY201421)EffectofTransplantingTobaccoSeedlingsunderPlas
