摘要
采用田间试验研究了灌水和过量施钾对烤烟 (NicotianatabacumL )养分含量和产量品质的影响 .结果表明 ,在烤烟N∶K2 O用量比达到 1∶3的基础上随钾用量增加 ,烟株体内营养元素含量、烟叶产量和化学成分均没显著差异 .灌水可以显著提高烟叶产量和上等烟比例 ,但灌水与钾用量互作对烤后烟叶养分含量和化学成分的影响不显著 .
Field experiment was conducted on the effect of irrigation and oversupplying of potassium on content of nutrients, yield, and quality of flue-cured tobacco(Nicotiana tabacum L.).The results showed that there were not significant differences in content of nutrients,yield,and chemical component of flue-cured tobacco with the increasing of potassium based on the 1∶3 proportion of nitrogen and potassium. It was also found that irrigation could significantly increase the yield and high quality leaves ratio, but no significant effect was observed of irrigation and rate of potassium interaction on the content of nutrients and chemical composition in leaves.
