摘　　要：水肥耦合效应对烤烟的品质有很大的影响,探讨不同灌水量与氮磷钾配比之间的耦合效应对烤烟质体色素及其降解产物的影响具有重要的现实意义。采用田间试验对不同水肥处理的烤烟质体色素及其降解产物含量进行研究。充足灌水、氮磷钾比例为1∶2∶3处理(T8)的类胡萝卜素和质体色素降解产物含量最高,限量灌水、氮磷钾比例为1∶2∶3处理(T5)次之;T5的叶绿素b和叶绿素总量最低;T8的叶绿素及其降解产物和类胡萝卜素均比T5高,但类胡萝卜素降解产物比T5低。水肥耦合效应的最佳组合为:充足灌水、每公顷施纯N60kg、P2O5120kg、K2O180kg,其叶绿素及其降解产物含量分别为:34.89μg/g和2702μg/g,类胡萝卜素及其降解产物含量分别为:384.1μg/g和73.83μg/g。Water and fertilizer coupling has great effect on the quality of flue-cured tobacco, so it has great impor- tance practical significance to study the effect of water and fertilizer coupling on chromoplast pigment and its degraded products in flue-cured tobacco leaf between the different of irrigates quantity and nitrogen phosphorus potassium pro- portion. Field experiment was carried out to study chromoplast pigment and its degraded products content under the different water-fertilizer conditions. The highest content of carotenoids and chromoplast pigment degraded products was T8 which was provided with enough water and the nitrogen phosphorus potassium proportion by 1 ： 2： 3, limited water and the nitrogen phosphorus potassium proportion by 1 ： 2：3 （T5） took second place, chlorophyll b and the total chloro- phyll of T5 was the lowest;The chlorophyll, chlorophyll degradation products and carotenoids of T8 were all higher than TS,but the degradation product of carotenoids is lower than T5. The optimum combinations of water and fertilizer coupling：enough water;N,P and K were 60,120 and 180 kg/ha respectively,chlorophylls and their degradation prod- ucts of which were 34.89 μg/g and 2 702μg/g respectively,carotenoids and their degradation products of which were 384. 1 μg/g and 73.83 μg/g respectively.
