摘要
杨树烂皮病是湖北地区近年来危害性上升迅速的林业有害生物,其主要寄主在湖北种植广泛。其病原金黄壳囊孢菌Cytospora chrysosperm侵染杨树枝干部,从而导致死亡。依据林业有害生物风险分析指标体系,采用多指标综合评价法对杨树烂皮病危险性进行定量化分析和评判。结果表明,杨树烂皮病在湖北省的危害风险值为2.01,即:杨树烂皮病在湖北地区为中度危险性的林业有害生物。此结果将为我省应杨树烂皮病的综合防控技术研究提供基础科学依据。
Cytospora canker of poplars is increasing swiftly in Hubei where poplars are widely planted, and the pathogen is Cytospora chrysosperm, which can infect branch and trunk of poplars and then weaken the tree or even lead to death. In this paper, multi-index method, which was based on the forest pest risk analysis index system of China, was employed to evaluate the risk of C. chrysosperm to poplars in Hubei. The risk value is 2. 01 in Hubei, which revealed that Cytospora canker possesses high risk to the poplars and other trees in local area. This research will provide fundamental evidence for the management of this disease.
