摘要
[目的]筛选青枯病的有效防治措施。[方法]通过小区试验研究了烟草-丹参轮作、土壤熏蒸处理、拮抗菌剂处理、链霉素处理对烟草青枯病的防效和烟叶产值的影响。[结果]拮抗菌剂处理对青枯病的防治效果较好,并且其产量、产值方面均表现较好。丹参茬处理均价及上中等烟比例较高。土壤熏蒸处理对烟草青枯病的防治效果相对较差。[结论]为达到较理想的防治效果,建议采用丹参轮作及使用拮抗菌剂对烟草青枯病进行综合防治。
[Objective] The aim was to screen out of efficient measures for tobacco bacterial wilt.[Method] Control effects of tobacco-Salvia miltiorrhiza rotation,soil fumigation,biological antibacterial agent and streptomycin sulfate against tobacco bacterial wilt and their effects on tobacco yield and output value were studied through plot test.[Result]Biological antibacterial agent had good effect and tobacco yield and output value;tobacco-Salvia miltiorrhiza rotation had good average price and the proportion of superior tobacco.Soil fumigation showed poor control effects against tobacco bacterial wilt.[Conclusion]To achieve ideal control effect,it is suggested that using tobacco-Salvia miltiorrhiza rotation and the biological antibacterial agent for comprehensive prevention and control of tobacco bacterial wilt.
