Abstract
The field experiment was conducted to study the effects of flue-cured tobacco and sweet potato(Ipomoea batatas ) intercropping, and flue-cured tobacco and sweet clover(Melilotus officinalis) intercropping on tobacco leaves yield and quality. The results showed that intercropping practice does not significantly influence the yield of tobacco leaves in comparison with monocropping. And compared with monocropping and intercropping of flue-cured tobacco and sweet potato, flue-cured tobacco and sweet clover intercropping increased the proportion of second grade leaves by 38.10% and 9.59% respectively, which are significant at P0.05. And compared with monocropping, intercropping of flue-cured tobacco and sweet potato, and flue-cured tobacco and sweet clover decreased the proportion of low-grade leaves by 12.61% and 2.39% respectively, which are significant at P0.05. Moreover, intercropping practice increased the contents of total sugar, reductive sugar and sugar/nicotine ratio, and decreased chlorine content in flue-cured tobacco leaves, making the leaves better in term of quality.
