通过3年田间试验，研究了烤烟与桔梗间作对烤烟农艺性状、病害发生、烟叶外观质量和烟叶效益的影响。结果表明，烤烟与桔梗间作与烤烟单作相比，株高、茎围、腰叶、顶叶均略高于单作烟田，但差别不大；当地发生的主要病害病毒病、角斑病与野火病、黑胫病、赤星病的发病率均明显低于单作烟田；原烟外观质量与单作烟田基本相当；单产及其烟叶产值均低于单作烟田，但间作烟田烤后烟叶上中等烟比例和均价均高于单作。加上桔梗产值，间作烟田的综合经济效益显著高于单作烟田。

Three -year old field experiments were conducted to study the effects of intercropped with platycodon on agronomic traits , disease occurrence , appearance quality and economic benefit of tobacco leav-es.The results showed that compared to monocropping , intercropping with platycodon increased the plant height, stem girth, lumbar leaf and parietal lobe of tobacco a little , and decreased the occurrence rate of main local diseases such as viral disease , angular leaf spot , wild fire disease , black shank and brown spot .There were no significant differences in appearance quality between intercropped and monocropped tobacco leaves . The yield per unit area and output value of intercropped tobacco leaves were lower than those of monocropped ones, but the proportion of superior tobacco and average price were higher .The comprehensive economic ben-efits of tobacco intercropped with platycodon were higher than that of monocropped .
