杨树水泡型溃疡病是我国杨树的主要病害之一。我国自1955年发现此病后,到目前已遍及华北、东北、西北等地区,分布广泛,蔓延迅速。我省尚无资料报道。我们曾于1979—1984年对该病在山西省的分布危害情况、发病规律、病菌特性、抗病品种的筛选等方面进行调查研究。本文着重阐述该病在我省的分布危害情况、病原菌形态特点、发病与杨树品种间的关系,以期为我省林木病害综合防治和林业经营布局提供依据。一、杨树水泡型溃疡病在我省的分布及危害情况近年来在我省运城、晋中地区和五台山林区都先后发现杨树水泡型溃疡病。晋中、
Poplar canker disease is one of the main diseases of poplar in China. After the disease was discovered in China in 1955, it has spread widely in north China, northeast and northwest regions and spread rapidly now. No data is reported in our province. In 1979-1984 we conducted a survey on the distribution of the disease in Shanxi Province, the incidence of disease, the characteristics of bacteria, screening of resistant varieties and so on. This article focuses on the distribution of the disease in our province, the morphological characteristics of pathogens, the relationship between disease and poplar varieties, in order to provide a basis for the comprehensive prevention and control of forest disease and forestry management layout in our province. First, the poplar blister-type ulcer disease distribution and damage in our province in recent years in our province Yuncheng, Jinzhong and Wutaishan have discovered poplar canker disease. Jinzhong,
