摘　　要：为探究云南省宣威市高海拔烟区优质烤烟品种的适宜施氮量,于2020年采用田间试验研究了3个烤烟品种在高海拔烟区不同施氮量的经济性状、物理特性、外观质量、化学成分和感官评吸质量的差异。结果表明,云烟105施氮量为97.5 kg/hm2时,经济效益最好,施氮量为112.5 kg/hm2时,烤烟综合品质最好;云烟301施氮量为97.5 kg/hm2时,有助于提高烟叶化学成分的协调性、感官评吸质量及外观质量,且综合品质较好,施氮量为112.5 kg/hm2时,经济效益最好;中川208施氮量为97.5、112.5 kg/hm2时经济效益和综合品质均有较好的表现,施氮水平较低时,有利于提高烟叶感官评吸质量,并使经济效益最大化,施氮水平较高时,有助于提高烟叶内在化学成分协调性和外观质量的形成,经济效益较好。综合来看,在宣威市高海拔烟区,云烟105、云烟301和中川208的适宜施氮量为97.5~112.5 kg/hm2。In order to explore the suitable nitrogen application rate for high-quality flue-cured tobacco varieties in the high-altitude tobacco area of Xuanwei City,Yunnan Province,the field test comparison method was adopted in 2020 to study the economic proper⁃ties,physical properties,appearance quality,chemical composition and sensory evaluation quality of three flue-cured tobacco variet⁃ies with different nitrogen application rates in the high-altitude tobacco areas.The results showed that Yunyan 105 had the best eco⁃nomic benefits when the nitrogen application rate was 97.5 kg/hm2,and the comprehensive quality of flue-cured tobacco was the best when the nitrogen application rate was 112.5 kg/hm2.When the nitrogen application rate of Yunyan 301 was 97.5 kg/hm2,it was help⁃ful to improve the coordination of chemical components,sensory evaluation quality and appearance quality of tobacco leaves,and the comprehensive quality was good;when the nitrogen application rate was 112.5 kg/hm2,the economic benefit was the best.Zhongchuan 208 had good economic benefits and comprehensive quality when the nitrogen application rate was 97.5 kg/hm2 and 112.5 kg/hm2.When the nitrogen application rate of Zhongchuan 208 was 97.5 kg/hm2,it was beneficial to improve the sensory evaluation quality of tobacco leaves and maximize the economic benefits.When the nitrogen application rate of Zhongchuan 208 was 112.5 kg/hm2,it was helpful to improve the coordination of internal chemical components and the formation of appearance quality of tobacco leaves,and the economic benefit was good.To sum up,in the high-altitude tobacco area of Xuanwei City,the suitable nitrogen application rates of Yunyan 105,Yunyan 301 and Zhongchuan 208 are 97.5 kg/hm2 to 112.5 kg/hm2.
