| 摘 要： | 采用田间试验研究了灌水和腐殖酸用量对旱区烤烟 (NicotianatabacumL .)养分含量及烟叶产量品质的影响。结果表明 :烟田施用腐殖酸可以提高烟株氮、磷、钾、铁的含量 ,且随腐殖酸用量的增加 ,烟叶产量、上等烟比例和烟碱含量显著增加 ,还原糖含量明显下降 ,总氮含量变化不明显 ;灌水对提高烟叶产量和上等烟比例有显著的作用 ;但灌水与腐殖酸互作对烟株养分含量和烟叶化学成分没有显著影响。

| Abstract: | The effects of irrigation and rate of humic acid on concentration of nutrients and yield and quality of flue-cured tobacco (Nicotiana tabacum L.) in dry land were studied by field experiment. The results showed that application of humic acid could increase the content of N, P, K, Fe in tobacco plant. With the increasing of humic acid, the yield, high quality leaf ratio and the content of nicotine in the cured leaves increased, the content of reducing sugar decreased, but the difference in the content of total nitrogen was not significant. It was also found that yield and superior leaf ratio of the leaves increased significantly with irrigation, but the interaction of irrigation with humic acid rates on the content of nutrients and chemical components of tobacco was not significant. |
