Field experiment were conducted to investigate the effects of flue-cured tobacco and sweet potato intercropping on quality and economic benefits of flue-cured tobacco leaves.The results were as follow: compared with monocropping, flue-cured tobacco intercropping with sweet potato the yield of flue-cured tobacco leaves were increased 117.99 kg per hectare and increased by 4.26％, the proportion of superior and middle tobacco leaves were increased by 3.24 %-14.53 % and 4.54 %-12.44 %, respectively, meanwhile the proportion of low-grade leaves was decreased by 10.08％ and 25.28％. The average price of flue-cured tobacco leaves were increased by 0.50-0.53 yuan per kilogram and the rise range was between 4.38 %-4.56 %. In addition, the sweet potato tube and bushrope yield were increased by 3226-7856 and 19 351-36 520 kilogram per hectare, respectively, income respectively increased by 3871-9427 and 5805-10956 yuan per hectare, the total economic income were increased 16 368-18 133 yuan per hectare and increased by 48.82 %-56.40 %, the different of producing value is significant at 5 % level．
