摘　　要：为明确香料烟杂交品种在云南德宏生态区适宜的施肥量,以巴斯玛11号×柯玛蒂尼为材料,通过设置不同的施氮量(0、37.5、75、112.5和150 kg/hm^(2))处理,采用随机区组试验设计进行小区试验,研究了不同氮肥条件下香料烟的农艺性状和产质量变化。结果表明:适宜的施氮量为112.5 kg/hm^(2),所收获的香料烟化学成分协调,产量达到3 135 kg/hm^(2),产值74 740元/hm^(2),均价23.8元/kg,AB级比例91.1%,田间收获的香料烟综合质量、产值、产量达到最优。因此,建议在德宏生态区香料烟的氮肥最佳施用量控制在112.5 kg/hm^(2)最为适宜。In order to know the suitable amount of nitrogen fertilizer applied for the hybrid oriental tobacco in Dehong ecological zone of Yunnan Province,different nitrogen application rates (0,37.5,75,112.5 and 150 kg/hm^(2)) were set in a random block experiment using ’Basma No.11× Komatini’ as tested material to study the agronomic characters,yield and quality changes of oriental tobacco under different nitrogen application rates.The results showed that the proper nitrogen fertilizer amount of ’Basma No.11×Komatini’ was 112.5 kg/hm^(2);under such conditions the harmony of chemical components of the harvested oriental tobacco reached the ideal state,with a yield of 3 135 kg/hm^(2),an output value of 74 740 yuan/hm^(2) and an average price of 23.8 yuan/kg;meanwhile the proportion of AB grade tobacco reached 91.1%;in addition,the harvested hybrid oriental tobacco was up to the best level in comprehensive quality,output value and yield.Therefore,it is suggested that the optimal nitrogen application rate of oriental tobacco in Dehong ecological zone should be controlled at 112.5 kg/hm^(2).
