摘　　要：为摸清海南省贡蕉重要病害种类,采用五点取样法在贡蕉种植主产区进行病害种类调查。经过田间症状观察和室内分离病原菌,共鉴定出7种病害,其中病毒类病害2种,真菌性病害5种。调查发现,在贡蕉种植区均有发生的病害有香蕉黄条叶斑病、香蕉灰纹病和香蕉束顶病,属于常发性重要病害,发病率分别为18.37%,10.69%,6.53%。在部分种植区发病比较严重的病害有香蕉煤纹病和香蕉黑星病,发病率分别为8.27%和6.56%。香蕉黑条叶斑病属于次发性重要病害,发病率为4.16%。香蕉花叶心腐病属于偶发性重要病害,发病率为3.24%。以上结果为贡蕉病害有效防控提供技术参考。To find out the important diseases of Gongjiao(Musa AA)in Hainan Province,the five-point sampling method was used to investigate the disease species in the main producing areas of Gongjiao.Seven kinds of diseases,including two viral diseases and five fungal diseases,were identified through field symptom observation and indoor isolation.yellow sigatoka,Cordana leaf spot,banana bunchy top were major diseases in all Gongjiao plantations,with incidence rates of 18.37%,10.69%and 6.53%,respectively.Guignardia leaf spot and Helminthosporium leaf spot were serious in some Gongjiao plantations,with incidence rates of 8.27%and 6.56%,respectively.Black sigatoka was a secondary serious disease,with an incidence rate of 4.16%.Cucumber mosaic virus banana strain was an important disease,occurring occasionally,with an incidence rate of 3.24%.The results provide a technical reference for the effective control of Gongjiao banana disease.
