| 摘 要： | 【目的】研究漂浮育苗条件下,探讨接种不同丛枝菌根真菌及其结合生防制剂对烟株不同生育时期农艺性状、青枯病抗病效果及烤后烟叶品质的影响。【方法】采用漂浮育苗技术培育烟苗,于播种期分别接种摩西球囊霉、聚丛球囊霉和生防制剂进行烟苗农艺性状、烟叶化学成分及抗病性等比较试验。【结果】与对照相比,各处理均可不同程度改良烟株农艺性状,优化总糖与烟碱、总氮与烟碱的比例,改善烟叶品质;接种摩西球囊霉的菌根苗＋生防制剂20mL对于改良烟株农艺性状和改善烟叶品质具有更好的效果,而接种聚丛球囊霉的菌根苗＋生防制剂20mL对青枯病的防治效果最好,接种摩西球囊霉的菌根苗＋生防制剂20mL次之。【结论】漂浮育苗时接种摩西球囊霉＋生防制剂（20mL）处理可更好的改善烟株综合素质。

| Abstract: | Objective]The objective of the current study was to investigate the effects of inoculating different arbuscular mycorrhizal fungus（Glomuse mosseae and Glomuse aggregatum） and biological control agent on agronomic traits, wilt disease resistance and qualities parameters at seeding stage in tobacco. Method]Floating seeding technique was used to grow the seedlings in the comparative experiment with inoculation of Glomuse mosseae, Glomuse aggregatum and biological control agents for tobacco agronomic characters, tobacco chemical components and disease resistance. Result]All four treatments resulted in improved agronomic traits and quality of tobacco compared to CK. The improvement in agronomic traits and qualities of tobacco was more pronounced in seedlings treated with inoculation of Glomuse mosseae and biological control agents （20 mL） compared to the other treatments. The plants treated with inoculation of Glomuse aggregatum and biological control agents （20 mL） showed highest resistance to wilt disease followed by the inoculation of Glomuse mosseae and biological control agents （20 mL） treatment. Conclusion]The results revealed that under control experimental conditions, inoculation of Glomuse mosseae and biological control agents （20 mL） improved the quality of tobacco. |
