摘　　要：为明确枸溶性钾肥对烤烟生长和钾素吸收的作用效果,采用盆栽试验研究了枸溶性钾肥与解钾菌液(Ensifer和Bacillus cereus strain)配施对烤烟生长及钾素吸收积累的影响。结果表明,枸溶性钾肥中配施解钾菌可促进烤烟生长发育,有利于烟株的早生快发;与单施硫酸钾肥相比,枸溶性钾肥与菌液配施的烟株根系鲜质量最高增加15.01%,烤烟烟叶叶绿素含量增加16.27%,烤烟根系活力提高17.07%;枸溶性钾肥与解钾菌液配施能够促进烟株对钾素的吸收,使钾素在烟株体内的分配更加合理;同时枸溶性钾肥与解钾菌液配施还可改善烤烟农艺性状,以枸溶性钾肥与Ensifer菌液配合施用的效果最佳。To investigate the effects of citrate soluble potassium fertilizer on the growth and potassium absorption of flue-cured tobacco, a pot experiment was conducted to study the application of citrate soluble potassium fertilizer combined with potassium dissolving bacteria liquid （Ensifer and Bacillus cereus bacteria） on the growth and potassium absorption and accumulation in flue-cured tobacco. The results showed that the application of citrate soluble potassium fertilizer combined with potassium dissolving bacteria liquid promoted the growth and development of flue-cured tobacco and was favorable to the early growth and fast development of tobacco plants. Comparing with potassium sulfate fertilizer, the fresh weight of roots, chlorophyll content and root vigor increased by 15.01%, 16.27% and 17.07%, respectively, after the application of citrate soluble potassium fertilizer combined with potassium dissolving bacteria liquid. The treatment also promoted the potassium absorption of tobacco plants and made the distribution of potassium in tobacco plants more reasonable. In addition, the application of citrate soluble potassium fertilizer combined with potassium dissolving bacteria liquid improved the agronomic traits of flue-cured tobacco, especially combined with Ensifer bacteria liquid.
