[目的]为烟叶生产中促进钾素吸收、提高烟叶的钾含量提供技术支持.[方法]以吉烟9号为供试品种,从钾素施肥方法和栽培方法2个方面进行田间试验,比较不同处理植株钾含量变化和其他化学成分含量变化,研究不同钾素施肥方法与技术对钾素吸收效应的影响.[结果]烤烟在不同的生育时期农艺性状有不同的变化,到成熟期处理5农艺性状最好,株高与对照差异显著;处理5根系活力旺盛,钾含量高于对照及其他处理.综合各化学成分含量比较,处理5各化学成分适中,各项指标最佳、效果最好;从不同处理对经济性状的影响看,处理5产值和均价均最高,与对照差异显著.[结论]合理施钾肥方法使烟叶产量与质量得到提高,烟叶总糖、还原糖含量增加幅度较小,烟碱含量降低,不同处理的钾含量整体比对照钾含量相对增加.处理5的施肥方法值得借鉴推广.

[Objective]The research aimed to provide technical support for promoting potassium absorption and enhancing the potassium content in tobacco leaves production.[Method]With the Jiyan 9th as tested variey,the changes of potassium content and other chemical composition in different treatment plants were compared,methods and techniques of different potassium fertilizer effects on the potassium absorption were studyed with field test from potassium fertilization methods and cultivation methods.[Result]There were different changes in agronomic traits at different growth stages,treatment 5 had the best characters in mature stage,plant height was significantly different with the control,and its root vitality and potassium were highter than the aontol and other treatment.With the comprehensive comparison of the contents of various chemical components,treatment 5 had the moderate chemical composition,and its various indicators and effects were the best as well.From different treatment effects on economic traits of view,the value and average price of treatment 5 were the highest,and they were significantly different with the control.[Conclusion]The yield and quality of tobacco were improved with the rational potassium fertilizer,tobacco total sugar,reducing sugar content were increased to a lesser extent,nicotine content was decreased.Potassium content of different treatments all relatively increased,compared to the control.Fertilization method of treatment 5 was worth learning to promote.
