调查表明,祁连山区林木病原菌有107种,造成病害134种。其中,叶部病害74种,干部病害38种,枝梢病害17种,种实、根部病害较少。病害发生种类随植被垂直分布和林区气候不同而变化,人为活动对林分的干扰破坏是诱发森林病害的重要因素。通过总结生产经验和试验筛选,提出了适宜祁连山区主要森林病害的植物检疫、抗病育种、林分抚育、经营管理、生物防治、物理防治及化学防治方法。
The survey shows that there are 107 kinds of forest pathogenic bacteria in Qilian Mountains, causing 134 kinds of diseases. Among them, there were 74 leaf diseases, 38 cadres diseases and 17 branch diseases, with less disease and root diseases. The types of diseases vary with the vertical distribution of vegetation and the climate of forest area. The disturbances and damages of artificial activities to forest stands are the important factors that induce forest diseases. Through summing up the production experience and the screening test, the paper puts forward the plant quarantine, disease resistance breeding, forest tending, management, biological control, physical control and chemical control methods suitable for the main forest diseases in the Qilian Mountains.
