Abstract: In order to investigate the effects of ridge styles and transplanting methods on the physical properties of tobacco growing soil,  the yield and quality of planted tobacco, this paper adopted field test method, selected tobacco variety named ‘Zhongyan 100’ as research material, and set up four treatments according to ridge and transplanting styles, including  transplanting over turtle-back membrane (T1), transplanting under turtle-back membrane (T2), transplanting under concave membrane (T3) and transplanting over concave membrane (T4). The effects of different treatments on soil physical properties and post-roasting tobacco quality were researched. The results showed that the single or combined treatment of concave ridge effectively enhanced the soil physical properties and improved the yield and quality of tobacco leaves. Among them, the best treatment was transplanting under concave membrane (T3). Compared with treatment T1, T3 improved soil moisture content and total gross porosity of each soil layer significantly, and reduced soil bulk density. Meanwhile T3 significantly promoted the coordination of chemical composition in cured tobacco leaves, increased neutral aromatic substances content in the upper leaves by 15.96%, improved the yield and output value significantly. Therefore, transplanting under concave ridge membrane, which was more conducive to improving the physical characteristics of tobacco planting soil and improving the yield and quality of cured tobacco leaves, was the best planting pattern for tobacco. The present research provided a theoretical basis for the appropriate planting pattern of tobacco in Zhoukou tobacco-planting area, Henan province.
