摘要
园林绿化林木病虫害防治是城市园林绿化养护的重要工作之一,防治效果直接影响和决定城市园林绿化质量,因而一直受到高度的重视。以宁夏彭阳县为例,近年来,国槐、白腊、海棠、油松等绿化树木频繁发生病虫害,严重威胁到城市水生态安全。基于此,必须明确和掌握城市园林绿化中加强林木病虫害防治的要点与策略。探讨了城市园林绿化中林木病虫害的发生特点与防治原则,重点从植物选择、栽培技术、生物防治、化学防治、物理防治5个方面论述城市园林绿化中加强林木病虫害防治的要点与策略。
The prevention and control of forest diseases and insect pests is one of the important work of urban landscaping maintenance,and its control effect can directly affect and determine the quality of urban landscaping,so it can always get high attention.Taking Pengyang County of Ningxia as an example,in recent years,the occurrence of diseases and insect pests of Chinese pseudoacacia,white ash,Begonia,Chinese pine and other greening trees has seriously threatened the ecological security of urban water.Based on this,it is necessary to make clear and master the key points and strategies of strengthening forest pest control in urban landscaping.This paper firstly analyzes and discusses the occurrence characteristics and control principles of forest tree diseases and insect pests in urban landscape afforestation,and then analyzes and discusses the key points and strategies of strengthening forest tree diseases and insect pests control in urban landscape afforestation from the five aspects of plant selection,cultivation technology,biological control,chemical control and physical control.
