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 to study the effects of irrigation and excessive potassium fertilization on the nutrient contents and yield and quality of flue-cured tobacco (Nicotiana tabacum L.). The results showed that when the N: K2O dosage ratio reached 1: 3, There were no significant differences in the contents of chemical elements and yield of tobacco leaves between the two treatments.The irrigation could significantly increase the yield of tobacco and the proportion of superior tobacco, but the interaction of irrigation and potassium had no significant effect on the nutrient content and chemical composition of the cured tobacco.
