摘要:

为研究打顶时期和打顶方法对烤烟‘K326’上部叶可用性的影响,采用田间小区试验进行研究。结果表明,生长正常的烤烟选择在中心花开放时打顶最适宜。当烟株发育不正常,特别是出现早花现象后,采用提早打顶后留杈烟栽培(驳枝)的补救措施,可以增加烟株有效叶片数,提高烟叶产量和产值,改善烟叶等级结构和烟叶品质,上部烟叶有趋中部化趋势,更加细腻、柔和,浓度及透气量有所降低。因此,在正常年份以中心花开放时打顶最适宜,异常年份在烤烟15片处留一个腋芽驳枝方法最适宜,能有效提高烤烟‘K326’上部叶的可用性。这对烤烟‘K326’上部叶可用性的提高,烟叶产质量的提升具有重要意义。

Abstract:

The field trials were studied to improve the usability of upper leaves of flue-cured tobacco Variety K326. The results showed that it was more appropriate to top than the others in flower of central flowers for the normal growth tobacco plants. However, it was more appropriate to branch after topping for the abnormal tobacco plants. Tobacco yields and qualities can be greatly increased by these measures. In a word, it suggests that it is very meaningful for the achievement of better yield and quality for K326.
