摘要： 为了探讨缓控释肥对南平烟区‘翠碧1 号’烤烟生长发育及品质形成的影响，通过田间试验，设置T1（N-P-K ＝ 7-8-20）、 T2（N-P-K=10-10-20）、T3（N-P-K=10-10-30）3 种缓控释肥处理，以常规施肥为对照（CK），系统分析了不同肥料处 理对烤烟农艺性状、干物质积累、氮钾素吸收与积累、烤后烟叶物理特性、化学成分、感官质量和经济性状的影响。结果表明： 缓控释肥配施对烤烟农艺性状影响不显著，但显著提高了干物质积累，尤其是T3 的根和叶干重显著高于其他处理；缓控释 肥处理促进了烟株对氮钾素的吸收与积累，其中T3 表现最佳；烤后烟叶的物理性状和外观质量得到了改善，化学成分的协 调性也有所提升，T1 和T2 的感官评吸质量得分最高，但T3 在经济性状方面表现最佳，其产值、均价和上等烟比例显著高 于其他处理。综上，缓控释肥一次性基施在南平烟区具有显著应用潜力，T1 处理更有利于烤烟产量和品质的提升。
