| 摘 要： | 通过大田试验研究了不同施钾措施对烤烟产量和品质的影响.结果表明,3次施钾(1/3于移栽前作基肥、1/3于移栽后30 d作追肥、1/3于移栽后60 d作追肥)的效果优于2次施钾(1/2于移栽前作基肥、1/2于移栽后30 d追施)和1次施钾(全部于移栽前作基肥),可以提高烤烟上等烟比例、产值和上部叶钾含量,降低烤烟下等烟比例、上部叶烟碱含量和钙的含量.在3个施钾处理之间,烟叶的总N,还原糖,P,Mg,B,Cu,Fe,Mn,Zn含量以及产量无显著差异.

| Abstract: | The effects of applying potassium at different stages on yield and quality of flue-cured tobacco were studied through field experiment.The results showed that applying potassium fertilizer at three stages(1/3 before transplanting as base fertilizer,1/3 on the 30 th day after transplanting as side-dressing fertilizer,1/3 on the 60 th day after transplanting as side-dressing) was superior to applying potassium fertilizer at two stages(1/2 before transplanting as base fertilizer,1/2 on the 30 th day after transplanting as side-dressing fertilizer) and applying potassium fertilizer at one stage(all before transplanting as base fertilizer).Applying potassium fertilizer at three stages increased percentage of high grade leaves,income and K content of upper leaves,decreased percentage of low grade leaves,nicotine and Ca content of upper leaves.The contents of total N,reducing sugar,P,Mg,B,Cu,Fe,Mn and Zn were not significantly different among three applying potassium treatments. |
