摘　　要：探究宣威烟区优质烤烟品种的适宜施氮量。本试验以‘云烟97’、‘云烟301’和‘中川208’为试验品种,于2020年采用田间试验对比方法,研究3个烤烟品种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性。结果表明,‘云烟97’在施氮量为82.5 kg/hm^(2)时烤烟化学成分最为协调,施氮量为97.5 kg/hm^(2)时烤烟外观质量、物理特性及感官评吸质量均最高,2个施氮水平下烤烟综合品质均最好,但施氮量为97.5 kg/hm^(2)时经济效益最高;‘云烟301’在施氮量为67.5 kg/hm^(2)、97.5 kg/hm^(2)、112.5 kg/hm^(2)时候均有较好的表现,施氮水平较低时有助于提高烤烟外观质量及物理特性,施氮水平较高时有助于提高烟叶化学成分协调性及经济效益;‘中川208’在施氮量为97.5 kg/hm^(2)时大田长势表现较好,经济效益较优,产值为72883.5元/hm^(2),烟叶综合品质较高,综合得分为0.72。综上所述,在宣威烟区,‘云烟97’和‘中川208’品种的最适宜施氮量为97.5 kg/hm^(2),‘云烟301’的适宜施氮量应由植烟地块土壤条件决定,在67.5~112.5 kg/hm^(2)之间均可。In order to explore the appropriate nitrogen application rate of high-quality flue-cured tobacco varieties in Xuanwei tobacco area,‘Yunyan 97’,‘Yunyan 301’and‘Zhongchuan 208’were used as test materials and the field trial comparison method was adopted to study the differences of economic traits,physical characteristics,appearance quality,chemical composition and sensory evaluation quality of the three varieties under different nitrogen application rates in 2020.The results showed that‘Yunyan 97’had the most harmonious chemical composition when the nitrogen application rate was 82.5 kg/hm^(2),and the appearance quality,physical characteristics and sensory evaluation quality of flue-cured tobacco were the highest when the nitrogen application rate was 97.5 kg/hm^(2).At the same time,the comprehensive quality was the best under both the two nitrogen application rates,and the economic benefit was the highest when the nitrogen application rate was 97.5 kg/hm^(2).‘Yunyan 301’had better performance when the nitrogen application rate was 67.5kg/hm^(2),97.5kg/hm^(2) and112.5kg/hm^(2).Relatively low nitrogen application rate was beneficial to improving the appearance quality and physical characteristics of‘Yunyan 301’,while,high nitrogen application rate was conducive to increasing the chemical composition coordination and economic benefits of tobacco leaves.When the nitrogen application rate of‘Zhongchuan 208’was 97.5 kg/hm^(2),the field growth performance of the variety was good,the economic benefit was high,and the output value was 72883.5 yuan/hm^(2).The comprehensive quality of tobacco leaves was superior,and the comprehensive score was 0.72.To sum up,in Xuanwei tobacco production area,the optimum nitrogen application rate for‘Yunyan 97’and‘Zhongchuan 208’is 97.5 kg/hm^(2),and the suitable nitrogen application rate for‘Yunyan 301’should be determined by soil conditions of the tobacco plot,which can be from 67.5 to 112.5 kg/hm^(2).
