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 effect of different N, P and K fertilizers on the inherent quality of flue-cured tobacco, we studied the effects of N, P and K fertilizers on the chemical constituents and neutral aroma components of flue-cured tobacco in Huili County, Sichuan Province in 2014 and K326 as materials. The results showed that the content of total sugar and reducing sugar, the ratio of sugar and alkali were still high, the contents of nicotine and total nitrogen were more suitable, and the content of chlorine was quite different. The ratio of NPK was 1: 1.6: 2.0 (T2) The content of nitrogen and alkali were all within 1, the ratio of potassium to chlorine in upper and lower leaves of T2 was the highest, and the ratio of potassium to chloride was the highest in the middle of 1: 0.5: 2.5 (T3) of T2. Different N, P and K fertilizers could effectively increase the contents of aroma components in flue-cured tobacco. The content of neutral aroma components in the upper and middle leaves were highest with the ratio of N, P and K being 1: 1.6: 2.0. Therefore, Effective measures of quality.
