【摘要】 [目的]研究白肋烟套种大白菜对烟菜病害和土壤肥力的影响,以便确定白肋烟与大白菜套作最佳栽培模式。[方法]调查套作栽培对白肋烟和大白菜病害的影响,对白肋烟农艺性状、产量、质量的影响,对白肋烟土壤养分的影响。[结果]调查发现,白肋烟与大白菜套作大白菜病毒病比单作田块发病较重,而软腐病霜霉病较轻,白肋烟病毒病发生比单作田块偏重,但是影响不大;试验发现,大白菜与白肋烟套作时白肋烟不同氮肥用量对白肋烟农艺性状没有影响,对产量和产值也没有明显影响,烟叶化学成分变化不大;土壤取样分析发现,大白菜套作白肋烟对土壤pH值没有影响或者影响很小,对有机质、碱解氮、速效磷含量有减少的趋势,对土壤速效钾含量没有影响。[结论]该研究为确定白肋烟与大白菜套作最佳栽培模式以及协调2个产业发展之间的矛盾提供了数据支持。更多还原

【Abstract】 ObjectiveThis study aimed to investigate the effects of burley and Chinese cabbage intercropping on disease occurrence and soil fertility in order to further determine the optimal burley and Chinese cabbage intercropping cultivation mode. 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.更多还原
