摘　　要：为提高上部烟叶可用性,采用在烤烟打顶后叶面喷施含钾肥料,研究其对烟叶物理特性、化学成分及评吸质量的影响。结果表明:在烤烟打顶后喷施含钾肥料可提高上部烟叶钾含量2.63%~19.30%;喷施硫酸钾+氨基酸+壳寡糖+胺鲜酯处理的烟叶物理特性指数、化学成分可用性指数和评吸总分可分别提高5.92%、31.15%、5.30%。因此,烤烟打顶后叶面喷施含钾肥料可提高上部烟叶钾含量和烟叶可用性。In order to improve the usability of upper flue-cured tobacco leaf,the effect of foliar-spraying different potassium fertilizer in a field experiment on the physical character,chemical component,smoking quality of flue-cured tobacco leaves were studied. The results showed that: Foliar-spraying potassium fertilizer after tobacco topping could promote the potassium content of upper flue-cured tobacco leaves by 2. 63% ~ 19. 30%. Foliar-spraying fertilizer including potassium sulfate + amino acid + chito-oligosaccharide + Diethyl aminoethyl hexanoate could promote the physical character index,chemical component index and total smoking quality of upper flue-cured tobacco leaves by 5. 92%,31. 15%,and5. 30% respectively. Foliar-spraying potassium fertilizer after tobacco topping could promote the potassium content and quality of upper flue-cured tobacco leaf.
