摘　　要：[目的]确定不同海拔和坡向生态条件下烤烟(Nicotiana tabacum)的产量和质量。[方法]烤烟品种为云烟87和云烟85。2009、2010年,在盐边县和爱乡于阴坡、阳坡,按海拔1 6001、800和2 000 m分别选择试验地0.125 hm2进行试验,观测烟叶生理性状和经济性状。[结果]阴坡与高海拔有利于促进烟株叶片宽大,但阴坡影响烟叶的内在品质,烟叶的产值和中上等烟叶比例低于阳坡。[结论]该研究可为烤烟生产的区域性布局提供科学参考。[ Objective ] The purpose was to confirm the yield and quality of flue-cured tobacco under different slopes and elevation. [ Method ] Flue-cured tofiacco variety was Yunyan 87 and Yunyan 85 respectively. The 0. 125 ha test fields in shady slope and sunny slope of 1 600, 1 800, 2 000 m position were chose in Heai township, Yanbian county in 2009 and 2010 to carry out the test, and observed and determined the physiological and economic characters of tobacco leaves. [ Result ] Shady slope and high elevation promoted tobacco leaves widen, while shady had influences on the inner quality of tobacco leaves, and the output value of tobacco leaves and the ratio of first and secondary class were lower than sunny slope. [ Conclusion] The study provides a scientific reference for regional layout of flue-cured tobacco oroduction.
