摘　　要：为改善烤烟品质,在等氮(施纯氮112.5 kg/hm^2)条件下,通过田间试验研究不同磷钾配比对K326成熟期农艺性状、经济性状、叶绿素含量、抗病性和品质的影响。结果表明:施肥方案2(T2处理),即施纯氮112.5 kg/hm^2、烟草专用复合肥(N∶P2O5∶K2O=1∶1.45∶3)1090.5 kg/hm^2+硫酸钾240 kg/hm^2较其它处理成熟期农艺性状好,打顶后叶绿素含量较低、利于落黄,抗病性较好(气候性斑点病、TMV和CMV都表现为抗病),产量达1693.35 kg/hm^2,每公顷产值为47007.40元,综合品质较好。综合来看,合理配施氮磷钾肥能改善烤烟农艺性状、减少田间病害发生、提高烟叶产量产值和品质。In order to improve the quality of flue-cured tobacco,the field experiment was conducted to study the effects of different application ratios of P and K fertilizer on agronomic traits,economic characters,leaf chlorophyll content,disease resistance and quality of K326 under the condition of applying equal N fertilizer( 112. 5 kg/hm^2 pure nitrogen). The results showed that the T2 treatment,which applying 112. 5 kg/hm^2 of pure nitrogen,1 090. 5 kg/hm^2 of tobacco special com;pound fertilizer( N∶ P2 O5∶ K2 O = 1∶1. 45∶3) and 240 kg/hm^2 of potassium sulfate,had better effects. Under the T2 conditions,the agronomic traits were better com;pared to the other treatments in mature period;the chlorophyll content was lower conducive to yellowing after topping;the disease resistances were higher to climate scab,TMV and CMV;the yield was 1 693. 35 kg/hm^2,and the output value was 47 007. 40 yuan per hectare;the com;prehensive quality was better. On the whole,rational application of nitrogen,potassium and phosphorus fertilizers could improve the agronomic traits of flue-cured tobacco,reduce the occurrence of diseases in field,and increase the yield,output value and quality of tobacco leaves.
