摘要
研究了不同氮磷钾配施对烤烟质体色素及其降解产物含量的影响,2008年在河南省洛宁县王岭现代烟草示范基地,以中烟100为材料,研究了氮、磷、钾肥配施对烤烟质体色素及其降解产物含量的影响。结果表明:不施肥处理烟叶质体色素及其降解产物含量都较低;氮、磷、钾任意两种肥料配施均可以不同程度提高烤烟质体色素及其降解产物的含量;氮磷钾的配施,随着施肥量的增加,烤烟的叶绿素、类胡萝卜素和新植二烯含量也随着增加,而类胡萝卜素降解产物含量呈现先增后减的抛物线。新植二烯和类胡萝卜素降解产物的总量以T6最高,因此,氮磷钾的合理配施(T6)是提高烤烟香气量的重要措施。
The effects of different combining application of N,P,K fertilizers on the chromoplast pigment and degraded products in Flue-cured tobacco leaves were studied.Field experiment was conducted to study the effects of the combining application of N,P and K fertilizers on the chromoplast pigment and degraded products in flue-cured tobacco leaves of a tobacco cultivar Zhongyan100 at Wangling of modernization tobacco agriculture in Luoning County of Henan province in 2008.Results showed that the chromoplast pigment and degraded products in tobacco leaves were the lowest in the treatment without fertilizer（CK）.Combining application of any two of N,P,K could increase the chromoplast pigment and degraded products.With the increment of N,P,K fertilizers,Chlorophyll,carotene and neophytadiene in flue-cured tobacco leaves increased continuously,while the contents of aroma products degraded from carotenoid increased at first then decreased,showed a shape of parabola.T6 had the highest total content of neophytadiene and Carotenoids,Therefore,reasonable combining application of N,P,K fertilizers（T6）is an important and effective measure of improving the amount of aroma in flue-cured tobacco.
