侧柏根系十分发达,耐干旱能力较强,是荒山造林、退耕还林的主要树种之一。近几年,我国林业项目中侧柏栽植面积越来越大,栽植数量越来越多,但受气候条件因素影响,很多省份侧柏在春季都会出现严重叶枯病,使受害林枯黄,给生态安全带来较大威胁。所以,相关林业管理部门必须加强侧柏叶枯病的研究,不断探索新的防治技术。基于此,主要介绍侧柏叶枯病的症状、侧柏叶枯病的病源与发病规律以及侧柏叶枯病的防治技术,旨在提高造林成效。
Arborvitae root is very developed, drought-resistant ability is barren hill afforestation, returning farmland to forest one of the main species. In recent years, the planting area of arborvitae in our country’s forestry project is more and more large and the number of planting is more and more. However, due to the influence of climatic conditions, arborvitae in many provinces will appear serious leaf blight in spring, Ecological safety poses a greater threat. Therefore, the relevant forestry management departments must strengthen the research on oriental leaf blight and continuously explore new prevention and control technologies. Based on this, we mainly introduce the symptom of oriental leaf blight, the pathogen and pathogenesis of oriental leaf blight, and the prevention and control technology of oriental leaf blight, so as to improve the afforestation effect.
