以‘HY-9-7'为材料,研究不同氮肥用量和留叶数对烤烟产量与主要品质指标的影响。结果表明:(1)烤烟产量随着施氮量的增加而显著提高,随着留叶数的增加呈先增加后下降的趋势,表现为留叶20片>留叶18片>留叶22片,各处理差异显著;烤烟产值随着施氮量及留叶数的增加均呈现先增加后下降的趋势。(2)烤后烟叶总糖、还原糖含量随着施氮量的增加而下降,N、K含量随施氮量增加而升高,烟碱含量随施氮量增加而显著提高。(3)烤后烟叶总糖、还原糖、K、烟碱含量均随留叶数增加而下降。(4)施肥量和留叶数的交互效应对烤烟产量、产值以及烟叶总糖、还原糖含量的影响均达显著水平。

A field experiment was conducted to study the nitrogen application rate and remained leaf number on yield and main quality traits of flue-cured tobacco with HY-9-7 as material. The results showed that： （1） the yield of flue-cured tobacco significantly increased with the increment of nitrogen rate, and it showed the increase-decrease trend with the increment of remained leaf number, and it showed 20 leaves 18 leaves 22leaves. The output value of flue-cured tobacco increased and then decreased with the increment of nitrogen rate and remained l...
