| 摘 要： | 1988年采用土培和田间试验结果表明,在本试验条件下,施用钾肥不仅能促进烟草生长发育,提高烟叶产量,还能改善烟叶内在及外观品质,主要体现在烟叶中钾、可溶性糖含量和施木克值及中上等烟比例等均明显提高,但不同种类钾肥对烤烟的生长发育,产量及外观品质的效应均无显著差异,仅炳叶中氯离子含量随氯化钾用量的增加而上升,K_2O/Cl~-比例则随之而降低。

| Abstract: | The pot and field experiments in 1988 showed that applying pot-assium fertilizers not only promoted plant growth and increased yields, but also improved quality of flue-cured lobacco.Different potassium fertizers did not pro-duce any remarkably different effects, except that chloride concentration in le-af increased with the increase of the application rate of potassium chloride. |
