摘　　要：[目的]对彰显凉山产区烟叶质量的适宜植烟密度进行研究。[方法]以云烟85为试验材料,采用小区对比试验,设置4个植烟密度处理,在2个行距移栽规格下,使用行株距进行试验。[结果]900和1000株/hm^(2)处理的农艺性状表现较好。900株/hm^(2)处理烤后烟叶的均价和上等烟比例较高,经济效益较好。900株/hm^(2)处理外观质量评价得分最高,表现较好。当行距为120 cm时,900株/hm^(2)处理总糖、还原糖含量较高,烟碱含量较高且适宜,钾氯比适宜。在行距为110 cm时,900株/hm^(2)处理烟碱含量适宜,氮碱比最接近最佳值,钾氯比最高且适宜,使得该处理化学成分表现较好。900株/hm^(2)处理烟叶香气质、香气量、余味且感官质量总分得分较高,质量档次较好。[结论]凉山烟区烟叶适宜种植密度为900株/hm^(2),该处理各指标均表现较好。[Objective]The research aimed to study the suitable planting density of tobacco to highlight the quality of tobacco leaves in Liangshan area.[Method]Yunyan 85 was used as the test material,and four tobacco planting density treatments were set up in the plot comparison test.Under the two row spacing transplanting specifications,the row spacing was used for the test.[Result]The agronomic traits of D1 and D2(900 and 1000 plants/hm^(2))were better.The average price of flue-cured tobacco leaves and the proportion of superior tobacco leaves after treatment D1 were higher,and the economic benefits were better.The appearance quality evaluation score of D1 was the highest and the performance was better.When the row spacing was 120 cm,the content of total sugar and reducing sugar in treatment D1 was higher,the content of nicotine was higher and suitable,and the ratio of potassium to chlorine was suitable.When the row spacing was 110 cm,the nicotine content of treatment D1 was suitable,the ratio of nitrogen to alkali was the closest to the optimal value,and the ratio of potassium to chlorine was the highest and suitable,which made the chemical composition of the treatment better.The aroma quality,aroma quantity,aftertaste and total score of sensory quality of tobacco leaves treated with D1 were higher and the quality grade was better.[Conclusion]The suitable planting density of tobacco leaves in Liangshan tobacco area was 900 plants/hm^(2),and all indexes of this treatment performed well.
