[Objective] In order to find the best Transplanting time of flue-cured tobacco at different altitudes in Panxi area. [Method] We choose PingShan Town Miyi County ,HeAi Town Yanbian County, PingDi Town RenHe County as exemplary base, and three representative experimental sites with different elevations of 1,600, 1800 m and 2000 m, respectively.Three different transplanting dates were designed in PingShan Town Miyi County ,HeAi Town Yanbian County, PingDi Town RenHe County,which were April 30 to May 5,May 8 to May 11,May 18 to May 20.This study was conducted with tobacco variety Yunyan 87 as a material to investigate how the different altitudes affect Transplanting time of flue-cured tobacco , under the medium of soil fertility.［Conclusion］The results showed that an optimal transplanting date was on April 30 to May 15 in Panxi area.The altitude 1 600~1 800 m an optimal transplanting date was on April 30 to May 15,The altitude more 1800m an optimal transplanting date was Before May 8.
