摘  要：
[目的]明确孔雀草与淡紫拟青霉2种生防因子协同作用防治烟草根结线虫的效果,为烟草根结线虫病的生物防治提供参考。[方法]通过田间试验研究烤烟间作孔雀草同时联合使用淡紫拟青霉对烤烟生长特性以及对根结线虫病发病情况的影响。[结果]孔雀草与淡紫拟青霉联合使用不仅能显著提高淡紫拟青霉对烟草根结线虫防治效果的稳定性,还能明显提高烤烟的农艺性状。烤烟间作孔雀草能显著增加烟株的叶片宽度,施用淡紫拟青霉能显著增加烤烟的叶片长度;在株高、茎围、最大叶长和最大叶宽上,孔雀草与淡紫拟青霉联合使用时均明显优于单一处理。单一施用淡紫拟青霉对根结线虫的平均防效为67.2%,施用淡紫拟青霉的同时间作孔雀草,平均防效在73%以上。[结论]孔雀草与淡紫拟青霉协同作用防治根结线虫有显著的增效作用。

摘  要：
[Objective] To find the synergism between Tagetes patula and Paecilomyces lilacinus against tobacco root-knot nematode,and to provide references for the biological control of tobacco root-knot nematode.[Method]Field test was carried out to research the effects of combined utilization of T. patula and P. lilacinus on the growth characteristics of flue-cured tobacco and the incidence of tobacco root-knot nematode. [Result] Combined utilization of T. patula and P. lilacinus not only significantly improved the stability of P. lilacinus on tobacco root-knot nematode,but also promoted the agronomic characters of flue-cured tobacco. Intercropping T. patula significantly increased the maximum width of tobacco,while P. lilacinus obviously increased the maximum length of tobacco. Combined utilization was significantly superior to single treatments in increasing the plant height,stem girth,the maximum length and maximum width of tobacco. The average control efficiency of single application of P. lilacinus was 67. 2%,while that of combined utilization of T. patula and P. lilacinus was more than 73%. [Conclusion] The synergism of T. patula and P. lilacinus shows obviously increase effects on tobacco root-knot nematode.
