[purpose] In order to explore the effects of different ridge on quality of flue-cured tobacco in Panxi Region.[methods]A field experiment was carried out in the random block design of the flat Town, Renhe District, Panzhihua city. Three treatment groups were set up:A double ridge planting method, wide planting method, and convent conventional method. [results] It shows that compared with the conventional ridge, ridge and narrow row cultivation and flat planting tobacco ridging on flue-cured tobacco growth period have no effects, but were beneficial to improve the agronomic traits of flue-cured tobacco; and its physiological and biochemical characteristics can be improved, the content of chemical components of tobacco leaves under cultivation and its proportion is better than conventional cultivation. The content of chemical composition and proportion of tobacco leaves in the width were better than that of conventional cultivation.
