摘　　要：为建立豫西烤烟优化栽培技术指标体系,以烤烟新品系LY1306为材料,采用L_9(3~4)正交试验设计,研究了施氮量(1.5~3.5 kg/667 m^2)、种植密度(900~1 100株/667 m^2)和留叶数(18~22片/株)3个因子对LY1306中性致香成分含量(质量分数)以及感官品质的影响。单因子效应分析表明:中性致香成分总量随着施氮量和种植密度的降低均呈现出先增加后降低的趋势,随着留叶数的增加呈现出先降低后增加的趋势。感官品质随着施氮量和种植密度的降低呈先增加后降低的趋势,随着留叶数的增加呈先增加后降低的趋势。双因素交互作用(互作)分析表明:施氮量和种植密度之间的互作效应对致香成分总量和感官评价的影响最大,在本试验区间内存在最大值。对中性致香成分和感官评价的数学模型分别进行模拟寻优,结果表明:种植密度为1 003株/667 m^2,留叶数为22片/株,施氮量分别为2.728 8 kg/667 m^2和2.282 4 kg/667 m^2时中性致香物质总量和感官评价最佳,为豫西中高肥力植烟土壤优质烟叶生产的优化技术组合。To establish optimal cultivation measures for flue-cured tobacco in western Henan,an L9（3-4）orthogonal experiment was conducted to study the effects of nitrogen rate（1.5-3.5 kg/667 m^2）,planting density（900-1 100 plant/667 m^2）and number of residual leaves（18-22 piece/plant）on the content of neutral aroma components and sensory evaluation of cv.LY1306.Single-factor analysis showed that the total content of neutral aroma components and sensory performance increased first then decreased with the decrease of nitrogen rate and planting density.With the increase of number of residual leaves,the total content of neutral aroma components decreased first then increased,while sensory evaluation outcome was on the opposite.A two-factor interaction analysis indicated that the interaction effect between the number of residual leaves and the nitrogen rate influenced the total content of neutral aroma components and sensory evaluation most significantly,and there existed a maximum in this experiment.Mathematical models for neutral aroma components and sensory evaluation were used to simulate and optimize the parameters separately,the results showed that when planting density,number of residual leaves and nitrogen rate were 1 003 plant/667 m^2,22 piece/plant and 2.728 8（or2.282 4） kg/667 m^2 respectively,the total content of neutral aroma components and sensory performance reached their maximum,which suggested that this combination was the optimized combination for producing quality tobacco leaves in tobacco-planting soils with high/moderate fertility in western Henan.
