摘要
为明确遵义烟区最适繁蚜的烤烟品种,比较7个品种的繁蚜量、烟株主要农艺性状的变化和单位面积蚜量动态,并计算不同品种的耐蚜指数。结果表明,贵烟1号的繁蚜量和烟株耐蚜性最好,其次是K326,建议选择贵烟1号和K326作为遵义烟区烟蚜茧蜂规模化繁殖体系中繁蚜的首选烤烟品种。
In order to determinate the most suitable tobacco varieties of Myzus periscae reproduction in Zunyi Tobacco Area, the reproduction amount of M. periscae, the main agronomic characters of tobacco plant and the aphid number in unit area on 7 varieties were compared , the tolerance index of different varieties were calculated. The results showed that the aphid reproductive number and the tolerance index of Guiyan-1 was the best, and K326 was the second. Guiyan-1 and K326 could be the suitable tobacco varieties of M. periscae for Mass Rearing of A. gifuensis in Zunyi Tobacco Area.
