To study the best flue-cured tobacco transplanting method and the suitable plastic film type in Panzhihua tobacco region, Sichuan Province, a randomized block, field experiment was carried out to estimate the effects of different transplanting method and plastic film type on the growth,yield and quality of tobacco seedling transplanting under film. The results indicated that, compared with the other treatments, 'Digging-fossa' with black plastic film transplanting could provide a suitable temperature environment pre and post film breaking, reached the survival rate 100% ,improved the agronomic properties, significantly increased the effective leaves, the biggest leaf area, the tobacco yield, output, average price and the proportion of superiorand middle tobacco, meanwhile, the content and the ratio of chemical compositions of tobacco leaf were suitable and most close to the appropriate content of high quality tobacco. Thus, application of 'Digging-fossa' with black plastic film transplanting the flue-cured seedling in Panzhihua had high survival rate and good effects on tobacco agronomic properties, yield and quality.
