烟草青枯病影响因子筛选

Screening of Impact Factors of Tobacco Bacterial Wilt

烟田连作导致低海拔烟区青枯病日渐严重,为筛选出土壤环境变化因子,并研究其对烟草青枯病的影响程度,开展了盆栽试验。研究结果表明,土壤中的硫酸铝盐和硫酸锰盐可能是青枯病流行的主要原因,可以通过调节这些因子的变化来达到抑制青枯病流行的目的。

Bacterial wilt became more and more serious in low altitude area. The filed experiment was conducted to screen some soil environment factors,and to study their effects on bacterial wilt. Results showed that the main cause for bacterial wilt may be sulphoaluminate and manganese sulfate, and through adjustment of these impact factors can control the prevalence of bacterial wilt.
