摘　　要：为研究不同氮磷钾配施对烤烟内在质量的影响,2014年于四川省会理县,以K326为材料,研究了氮磷钾配施对烤烟化学成分和中性致香物质含量的影响。结果表明,各处理的总糖和还原糖含量、糖碱比仍较高,烟碱、总氮含量较适宜,氯含量差异较大,氮磷钾比例为1∶1.6∶2.0(T2)处理钾含量最高,氮碱比均在1以内,T2处理上部和下部叶钾氯比最高,氮磷钾比例1∶0.5∶2.5(T3)处理中部叶钾氯比最高。不同氮磷钾配施可有效提高烤烟各类致香物质的含量,上部和中部叶中性致香物质含量均以氮磷钾比例1∶1.6∶2.0的处理最高,因此,该处理是提高烟叶质量的有效措施。In order to study the effects of different combining application of nitrogen phosphorus and potassium on the intrinsic quality of flue- cured tobacco, we took flue-cured tobacco variety K326 as experimental material and researched the effects of different combining application of nitrogen phosphorus and potassium on the chemical composition and neutral aroma composition in Huili County of Sichuan Province in 2014. The results showed that ： total sugar; reducing sugar content and ratio of reducing sugar and nicotine were still high. Content of nicotine, total nitrogen were suitable, and content of chlorine were different obvious, the ratio of nitrogen phosphorus and potassium was 1：1.6：2.0. Content of potassium of T2 was the highest, and ratio of nitrogen and nicotine was less than 1. Ratio of potassium and chlorine of the upper and lower leaves of T2 were higher, the ratio of nitrogen phosphorus and potassium was 1：0.5：2.5, while the middle leaves of T3 was the highest. Differ- ent combining application of nitrogen phosphorus and potassium could increase the content of all kinds of neutral aroma component, and the content of all kinds of neutral aroma component of upper and middle leaves of T2 were higher. Therefore, T3 is an effective measuer of impro- ving the quality of the flue-cured tobacco.
