Abstract: The field experiments were conducted to study the effects of tobacco and sweet potato intercropping, tobacco and sweet clover intercropping on leaves potassium content and virus diseases occurrence of tobacco. The results showed that the intercropping practice could reduced tobacco virus disease occurrence; especially tobacco mosaic virus(TMV)、tobacco etch virus (TEV).The occurrence of TMV, TEV decrease by 77.24%~83.1% , 80%~100% respectively in intercropping in comparison with that of monocropping. Leave potassium contents of tobacco increased by 0.05%~0.92% in intercropping in comparison with that of monocropping.
