摘　　要：对衡水市桃城区的公共绿地进行实地徒步调查,结果发现:桃城区公共绿地的园林植物种类繁多,植物病害主要有流胶病、叶斑病、白粉病、煤污病、枯萎病、病毒病6种,发病部位主要为叶片和枝条。衡水市在植物病害研究和防治方面主要存在的问题是:植物单一,群落结构不稳定,植物容易受病原菌的侵害;广场等地的硬质铺装,街道边人造树池等不利于植物的呼吸和水肥的吸收,造成生长势衰弱易得病害;前进街植物绿化密度过大,影响植物的通风、透光,树势容易衰减,造成病害的猖獗;后期养护普遍不到位。针对病害发生的原因和出现的问题,提出的建议是:增加植物种类,建立稳定的群落结构,增强树势;改变观念,园林绿化重视养护,培训专业技术人员,及时合理地加强街道、住宅区、公园等绿地的植物养护;科学合理地使用农药,及时发现并治疗植物病害。The public green space in Hengshui Taocheng District has been investigated by way of field hiking.The results show that:there are many kinds of garden plants in the public green space in Taocheng District.There are mainly 6 kinds of plant diseases,which mainly occur in leaves and branches,such as gummosis,leaf spot,powdery mildew,coal pollution,blight and virus.There are mainly the following problems in the research and prevention of plant diseases in Hengshui City:The instability of community structure caused by single plant makes plants vulnerable to pathogen;the hard-paved square and other places,the artificial tree pool along the street are not proper for the respiration of plants and the absorption of water and fertilizer,resulting in the weak growth of trees and being easy to get disease;in Qianjin Street,the density of plants is too high,which affects the ventilation and light transmission among plants and causes the tree growth potential to decay easily and the disease is rampant.Generally inadequate postcuring.In view of the causes and problems of diseases in Hengshui City,the following suggestions are proposed:increase plant species,establish stable community structures and enhance tree potential;change our perceptions and strengthen the maintenance of plants in streets,residential areas,parks and other green spaces in a timely and reasonable manner by training professional and technical personnel;use pesticides scientifically and reasonably,detect and treat plant diseases in time.
