Abstract：Field experiment was conducted to explore the effects of ridging direction and conservation tillage on yield and quality of flue-tobacco in Shizhu,Chongqing mountains area in 2014.The differences of soil fertility and yield and quality of flue-cured tobacco among the six treatments were studied.The treatments were:T1 (longitudinal ridge,no cover),T2 (longitudinal ridge,corn straw was covered in interrow),T3 (longitudinal ridge,Lolium multiflorum Lam was covered in inter-row),T4 (contour ridge,no cover),T5 (contour ridge,corn straw was covered in inter-row),T6 (contour ridge,Lolium multiflorum Lam was covered in inter-row).The results showed that conservation tillage could improve soil fertility,and contour ridge was superior to the longitudinal ridge,in which T5 was the best.In addition to the contents of total sugar,reducing sugar and sugar alkali ratio,the rest of the conventional chemical components of tobacco leaves all conformed to the standard of high quality tobacco leaves.The contents of petroleum ether extracts,neutral aroma constituents,yield and output value of T5 treatment reached the highest with 9.93％,997.43 μg/g,2 246.40 kg/ha and 40 055.55 RMB/ha respectively.On the whole,T5 treatment was the best on improving soil fertility and the quality of mountain flue-cured tobacco.
