MethodsEffects of burley and Chinese cabbage intercropping on disease occurrence, burley agronomic traits, yield and output value, and soil nutrients were investigated. ResultsThe results showed that for Chinese cabbage, viral diseases was severer, but the soft rot was lighter in the field with burley and Chinese cabbage intercropping compared to that with monocropping, and for burley, the viral disease was severer in the field with burley and Chinese cabbage intercropping compared to that with monocropping, with no significant difference; under the burley and Chinese cabbage intercropping mode, nitrogen input had no effect on burley agronomic traits and no significant effect on the yield and output value, and there was minor change in tobacco chemical components; burley and Chinese cabbage intercropping had no or little influence on soil pH, and and no effect on rapidly available potassium content in soil, but there is descending tend in organic matter, nitrogen and available phosphorus content. ConclusionThe study provides data support for the determination of the optimal burley tobacco and cabbage intercropping mode and the coordination of the development of these two industries.展开更多
