Abstract: Using the low ridge and no plastic film mulching as control, high ridge and plastic film mulching as treatment, the suitability of high ridge and plastic film mulching technology in tobacco-growing area in Chenzhou city was investigated, the suitable transplanting period and depth was found. Two factors, transplanting time and transplanting depth, each with three gradients, were used to compare the agronomic characters, economic benefits, chemical composition, coordination and sensory evaluation quality of tobacco leaves in each experimental area at maturity by using the randomized block experiment. The results show that the high ridge and plastic film mulching technology can ensure the normal growth of tobacco plants under normal or dry climate. The agronomic traits, economic benefits, chemical components, coordination and sensory evaluation of tobacco plants with high ridge and plastic film mulching are better than the control tobacco plants. High ridge and plastic film mulching technology is suitable for tobacco-growing area in Chenzhou city. The yield and quality of tobacco would be the best by using D2S3 treatment (transplanting period is March 16, transplanting depth 20 cm).

Key words: flue-cured tobacco, high ridge and plastic film mulching, transplanting period, transplanting depth, Chenzhou city
