摘要
采用绿色木霉菌和抗生素溶杆菌菌剂对苗期和大田期烟草进行喷施处理,研究它们对烟草农艺性状及黑胫病、野火病发病情况的影响.结果表明:苗期喷施质量浓度为2.50 g/L的绿色木霉菌菌剂,对提升烟草素质效果好;大田期喷施质量浓度为2.50 g/L的抗生素溶杆菌菌剂,对提高大田烟草农艺性状的各指标效果好;抗生素溶杆菌菌剂对大田烟草野火病防治效果较好,而绿色木霉菌菌剂对大田烟草黑胫病的防治效果较好,它们的最佳喷施质量浓度都是2.50 g/L.
Spraying the seedling-stage and field period tobacco with Trichoderma viride and Lysobacter antibioticus microbial inoculum studies the effects of Lysobacter antibioticus and Trichoderma viride on agronomic trait, the incidence of black shank and wildfire diseases. The results suggested that 2. 50 g/L Trichoderma viride microbial inoculum significantly increased the agronomic characters index in seedling-stage. The Lysobacter antibioticus microbial inoculum concentration of 2. 50 g/L significantly increased the agronomic characters index in field period. The Lysobacter antibioticus had better control effect on tobacco wildfire disease, and the Trichoderma viride had better control effect on tobacco black shank, equally, optimal concentration of 2. 50 g/L.
