摘要
[目的]为合肥地区的番茄根结线虫病和青枯病的防治提供理论依据。[方法]选用西粉3号番茄在试验基地进行基质栽培试验,从青枯病发病率的差异和相对电导率的差异的角度,探讨根结线虫的入侵对青枯病发生的影响,并对合肥地区侵染番茄的根结线虫进行鉴定。[结果]当南方根结线虫与青枯菌同时入侵番茄时,青枯病的发病率在70%~100%;而没有根结线虫入侵,青枯病的发病率仅为30%。[结论]合肥地区侵染番茄的根结线虫为南方根结线虫。在生产上,有根结线虫存在的田块,在进行番茄青枯病的防治时,应考虑到根结线虫的防治。
[Objective] The study aimed to provide theoretical basis for controlling tomato root-knot nematodes and bacterial wilt in Hefei area. [Method] The tomato variety Xifen 3 was selected to conduct the substrate cultivation test. The effect of infection of root-knot nematodes on the incidence of bacterial wilt was discussed from the view of the difference of incidence of bacterial wilt and the change of relative conductance. The infected root-knot nematodes in Hefei area were identified. [Result] When the tomato plants were infected by root-knot nematodes and bacterial wilt simultaneously, the incidence of wilt disease was 70 %-100 %, but when the tomato plants were only infected by bacterial wilt, the incidence of wilt disease reduced to be 30 %.[Conclusion] The root-knot nematodes infecting tomato in Hefei district were south root-knot nematodes. In production, the control on root-knot nematodes should be considered when the control on bacterial wilt disease was conducted in the field that root-knot nematodes existed.
