摘　　要：为分析烤烟菽麻间作对烟草根结线虫的防治效果,以烤烟品种云烟87和菽麻品种I48为材料,通过田间试验研究了3种烤烟菽麻间作方式对烤烟根结线虫防效,烤烟农艺性状、产量及产值的影响。结果表明,与烤烟单作处理相比,烤烟与菽麻间作方式为2∶1时,根结线虫的防效为41.67%,能改善烤烟的农艺性状,烟叶产量、产值和均价分别提高了456.69kg/hm^2、16 550.65元/hm^2和4.15元/kg;烤烟与菽麻间作方式为1∶1时,根结线虫的防效为53.53%,并显著改善烤烟的农艺性状,烟叶产量、产值和均价分别增加了843.85 kg/hm^2、30 295.42元/hm^2和6.39元/kg;烤烟与菽麻间作方式为2∶3时,根结线虫防效为64.23%,降低了烤烟的株高,对烟叶产量产值等无明显提高。因此,烤烟与菽麻间作对根结线虫病具有良好的防治效果,并且能够显著提高烟叶产量、产值,以1∶1间作方式为最佳。To analyse the effects of intercropping flue-cured tobacco with C. junce L. on controlling tobacco root-knot nematodes, a field experiment was carried out to study the effects of three different modes of intercropping tobacco with C. junce L. on root-knot nematode control efficiency, tobacco agronomic traits, yield, value of output and average price, using materials tobacco Yunyan 87 and C. junce L.I48. The results showed that, when the intercropping mode of tobacco to C. junce L. is 2 to 1, the agronomic traits of flue-cured tobacco were improved, with a nematode control efficacy of 41.67%, and the yield, value of output and average price of tobacco were increased by 456.69 kg/ha, 16 550.65 yuan/ha and 4.15 yuan/kg, respectively. When the intercropping mode of tobacco to C. junce L. is 1 to 1, the agronomic traits of flue-cured tobacco were improved significantly, with a nematode control efficacy of 53.53%, and the yield, value of output and average price of tobacco was increased by 843.85 kg/ha, 30295.42 yuan/ha and 6.39 yuan/kg, respectively. When the intercropping mode of tobacco to C. junce L. is 2 to 3, the plant height was reduced with a rate of 3.94% but no significant difference of the agronomic traits was observed compared with the no intercropping treatment. Tobacco yield was increased by 7.49 kg/ha, and the value of output and average price were reduced by 77.64 yuan/ha and 0.13 yuan/kg, respectively. These results indicated that 1 to 1 is the appropriate intercropping mode of tobacco to C. junce L. in controlling the damage caused by tobacco root-knot nematodes.
