随着人们对环境质量要求的不断提高,建设园林生态城市的呼声日益高涨,许多城市逐步开展大规模园林绿化建设。城市绿化具有改善视觉、美化环境、提升城市品位等功能。随着城市园林绿地的大量增加,随之而来的是城市园林植物日益严重的病虫害问题,成为人们不得不重视的一个重要课题。以往防治病虫害就是将害虫和病原微生物赶尽杀绝,这个观点在大多数人的思想中根深蒂固,而用可持续发展的观点,就必须更新这一旧有的观念,要容忍有害生物的存在。对有害生物不应只注重于杀死,更要注重于调节,只要把危害控制在不影响植物观赏效果就可以了。
With the continuous improvement of environmental quality requirements, the voice of building eco-city gardens is on the rise, and many cities are gradually implementing large-scale landscape construction. Urban greening has the function of improving the vision, beautifying the environment and upgrading the city grade. With the large increase of urban garden green space, the pest and disease problems that are increasingly serious in urban garden plants are followed, and become an important issue that people have to pay attention to. In the past, pest and pathogenic microorganisms had been ruthlessly eliminated in the prevention and control of pests. This view is deeply rooted in the minds of most people. From a sustainable development perspective, it is necessary to update this old concept and tolerate the existence of pests. The pest should not only focus on killing, but also on the regulation, as long as the harm control does not affect the plant ornamental effect on it.
