随着果树树种品种调整范围的扩大和频率的加快,跨国界、跨地区的引种越来越多,植物检疫工作显得越来越重要,这是从源头上防治病虫害的关键环节。植物检疫是国家或地区政府为了防止危险性有害生物随植物及其新产品的人为引入和传播,以法律手段和行政措施强制实施的植物保护措施。因此,植物检疫又叫法规防治。北方果树检疫性病虫害种类主要有苹果绵蚜、美国白蛾、杏仁蜂、猕猴桃溃疡病等。根据各地区果树生产上病虫害发生情况,在选择树种、品种时要有意识地选择对本地区易发生病虫害有一定抗性的树种和品种,以减轻病虫害发生的程度,进
With the expansion and frequency of the adjustment of the species of fruit trees, more and more transnational and trans-regional introductions are made, and phytosanitary work is becoming more and more important. This is a key link in the prevention and control of pests and diseases at the source.

Therefore, phytosanitary is also called regulation and control. The main types of quarantine pests in northern fruit trees are apple aphid, white moth, almond bee, kiwi canker and so on. According to the occurrence of pests and diseases in the production of fruit trees in various regions, tree species and varieties with certain resistance to pests and diseases that are prone to occur in this region should be consciously selected when selecting tree species and varieties in order to reduce the occurrence of pests and diseases.
