摘　　要：为研究玄参根腐病的生物防治措施,以贝莱斯芽孢杆菌为供试材料,通过在定植期、苗期和营养生长前期使用,研究不同处理方式对玄参根腐病的防治效果。结果表明,贝莱斯芽孢杆菌对玄参根腐病防治效果较好,其防治效果受使用时间影响较大,定植期使用效果优于苗期和营养生长前期。使用次数对防治效果影响较大,同在定植期使用,追施2次效果优于1次。在连续使用3次的情况下,其田间防效最高可达77%。该研究可为玄参根腐病的有效防控提供指导依据。In order to study the biological control measures of root rot of Chinese figwort,Bacillus velezensis was used as the test material to estimate the control effects of different treatment methods on root rot of Chinese figwort at the planting stage,seedling stage,and early vegetative growth stage.Results showed that Bacillus velezensis had a good control effect on root rot of Chinese figwort and its control effect was greatly affected by the application time.The control effect of using at the planting stage was better than that of seedling stage and early vegetative growth stage.The frequency of use had a significant impact on the control effect,and the effect of reused twice was better than once in the same planting period.Under the condition of continuous use for three times,its field control effect could reach a maximum of 77%.This study provides an important guiding basis for the effection prevention and control of Chinese figwort root rot.
