摘　　要：为明确会理烟区植烟土壤海拔高度对烤后烟叶含梗率及相关物理性状的影响,设置4个海拔高度区间,跟踪调查了4个海拔高度上烤后烟叶含梗率、单叶重、叶面积、叶片厚度及叶质重指标的变化。结果表明:当海拔高度达到2000 m以上时,对X2F和C3F等级烤后烟叶含梗率影响显著,2021年增幅最大为>2000~2200 m海拔高度处理(19.96%和12.75%),2022年增幅最大为>2200 m海拔高度处理(26.16%和17.63%);随着海拔的升高,烤后烟叶单叶重、叶面积和叶质重总体呈下降趋势;海拔高度与含梗率成正相关关系,与叶面积、叶片厚度、叶质重和单叶重成负相关关系,其中受影响最大的是X2F和C3F等级烟叶。In order to clarify the effects of altitudes on the stem content and related physical properties of cured tobacco leaves in Huili tobacco growing area,this study set up four altitude intervals to investigate the changes in stem content,single leaf weight,leaf area,leaf thickness and weight per unit leaf area of cured tobacco leaves.The results showed that when the altitude reached above 2000 m,the effect on the stem content of X2F and C3F grade cured tobacco leaves was significant.In 2021,the maximum increase was in the treatment at an altitude of>2000-2200 m(19.96%and 12.75%),and in 2022,the maximum increase was in the treatment at an altitude of>2200 m(26.16%and 17.63%).As the altitude increased,the overall trend of single leaf weight,leaf area and weight per unit leaf area of cured tobacco leaves decreased.Altitude was positively correlated with stem content,but negatively correlated with leaf area,leaf thickness,weight per unit leaf area and single leaf weight.Among them,X2F and C3F grade tobacco leaves were affected greatly.
