通过对辽西地区6个乡镇10个苹果园2010年苹果树腐烂病发病情况进行调查,初步明确了辽西地区苹果树腐烂病的发病率与品种关系不密切,与树龄和管理方式关系密切;发病类型中的枝枯型发病与灌溉关系密切,发病部位以剪锯口发病最多,病斑复发所占比例也较大。加强田间管理、合理修剪、病斑刮治、伤口保护是防治苹果树腐烂病的关键。
By investigating the incidence of apple tree rot disease in 10 apple orchards in 6 towns and 10 western Liaoning Provinces in 2010, it was initially clarified that the incidence of apple tree rot disease in Liaoxi region was not closely related to the cultivars and was closely related to the tree age and management style. The incidence type In the incidence of branch blight and irrigation are closely related to the incidence of parts to cut the most incidence of kerf mouth, lesion recurrence accounted for a larger proportion. Strengthening field management, reasonable pruning, disease curettage, wound protection is the key to control apple tree rot disease.
