摘　　要：【目的】为明确不同因素对烤烟茎叶夹角的影响。【方法】2019—2021年,在不同烟区设置不同试验,研究不同品种、气象、密度、施氮量等因素变化对烤烟茎叶夹角的影响,并分析不同因素的影响程度。【结果】(1)不同烤烟品种茎叶夹角差异显著,根据聚类分析将其分为茎叶夹角小、中、大三种类型,夹角小代表品种为红花大金元,夹角中代表品种包括中烟100、K326、云烟87等,夹角大代表品种为CB-1;(2)随移栽期推迟,茎叶夹角表现出减小的趋势,气温升高及累积光照辐射减少是影响夹角变化的主要气象因素,降水对夹角的影响不显著;(3)随株距增大、密度减小,茎叶夹角呈现出增大的趋势;部分试验随施氮量增加,茎叶夹角呈现增大趋势;(4)不同因素处理条件下茎叶夹角与农艺性状相关性不一致,品种因素下茎叶夹角与茎围正相关性较高,密度因素下茎叶夹角与叶片干重存在显著正相关性,而移栽期、施氮量条件下茎叶夹角与农艺性状无明显相关性;(5)不同因素对茎叶夹角的影响程度顺序为品种>密度>移栽期>施氮量。【结论】烤烟茎叶夹角受品种自身遗传因素的影响最大,其后依次为种植密度、气象条件,施氮量影响最小。[Objective]This study aims to clarify the effects of different factors on stem-to-leaf angle of flue-cured tobacco.[Methods]From 2019 to 2021,different experiments were set up in different regions to study the effects of varieties,meteorology,density,nitrogen application rate on stem-to-leaf angle of flue-cured tobacco,and analyze the impact degree of each factor.[Results](1)There were significant differences in stem-to-leaf angle among different flue-cured tobacco varieties.According to cluster analysis,they were divided into three types:small,medium and large stem-to-leaf angle.The representative variety with small stem-to-leaf angle was Honghua Dajinyuan,the representative varieties with medium stem-to-leaf angle included Zhongyan100,K326 and Yunyan 87,and the representative variety with large stem-to-leaf angle was CB-1.(2)With the delay of transplanting period,the stem-to-leaf angle showed a decreasing trend.The increase of temperature and the decrease of cumulative photo radiation were the main meteorological factors affecting the stem-to-leaf angle,and the influence of precipitation on stem-to-leaf angle was not significant.(3)The stem-to-leaf angle increased with the increase of plant spacing and the decrease of plant density.The stem-to-leaf angle increased with the increase of nitrogen application rate in some experiments.(4)The correlation between in partial experiments and agronomic characters was inconsistent under different factors.The positive correlation between stem-to-leaf angle and stem circumference was higher under variety as a factor,and there was a significant positive correlation between stem-to-leaf angle and leaf dry weight under density as a factor,but there was no significant correlation between stem-to-leaf angle and agronomic characters under transplanting period and nitrogen application rate.(5)The impact degree of different factors on stem-to-leaf angle was in the order of variety>density>transplanting period>nitrogen application rate.[Conclusion]The stem-to-leaf angle of flue-cure
