摘　　要：采用L9(34)正交试验法,于2019年在四川省宜宾市兴文县仙峰乡群鱼村研究了不同种植密度、施氮量和留叶数对云烟116农艺性状、经济性状、外观质量等指标的影响。结果表明生育期随施氮量的增加而延长;株高、叶面积随施氮量的增加而增加;叶面积随种植密度和留叶数的增加有逐渐减小的趋势。种植密度、施氮量和留叶数对烟叶经济性状有极显著的影响,且对身份、油分、色度、单叶重影响较大。综合各项指标,种植密度15750株/hm^2、施氮105 kg/hm^2和留叶数20片/株为最优组合。The orthogonal experiment L9(34)was used to study the effects of different planting density,nitrogen application amount and leaf number on agronomic characters,economic characters,appearance quality of Yunyan 116 in Xingwen County,Yibin city Sichuan province in 2019.The results showed that the growth period of tobacco was prolonged with the increase of nitrogen application,plant height and leaf area increased with the increase of nitrogen application,the leaf area decreased with the increase of planting density and leaf number.The planting density,nitrogen application amount and leaf number had significant effects on economic characters of tobacco,and also had great influence on identity,oil content,color and leaf weight.According to all the indexes,planting density of 15750 plants/hm^2,application nitrogen of 105 kg/hm^2 and leaf number of 20 leaves/plant were the optimal combination.
