摘要
为研究不同移栽期的打顶方式对烤烟‘红花大金元’上部烟叶分割特色的影响,采用田间随机区组试验进行研究。结果表明,3月25日移栽采用中心红花开放打顶和盛花打顶,4月1日移栽采用中心花开放打顶,4月5日采用中心花开放打顶可以降低上部烟叶烟碱含量,同时有助于提高下部烟叶烟碱含量,提高烟叶整体质量。综合可知,烟叶适时提早移栽,搭配中心花开放或者盛花开放搭配的打顶方式,可以有效降低上部烟碱含量。
In order to study the influence of topping method in different transplanting periods on cuttingcharacteristics of‘Honghuadajinyuan'upper leaves, a field randomized block experiment was carried out.According to the results, the topping of central red flowers during blooming and the topping during full-bloomstage on March 25, the topping of central flowers during blooming on April 1, and the topping of central flowersduring blooming on April 5 can reduce the nicotine content of upper leaves, increase the nicotine content oflower leaves as well as improve the overall quality of tobacco leaves. To sum up, early transplanting of tobaccoleaves with topping of central flowers during blooming and topping during full- bloom stage can effectivelyreduce the nicotine content of upper leaves.
