近年来,随着生态建设步伐的加快,杨树种植面积逐年扩大,长期单一树种的形成,常常导致一些病虫害的发生。根据近年来的调查发现,经常发生的杨树病害以杨树黑斑病、杨树叶锈病、杨树溃疡病和杨树烂皮病为主。害虫主要有蛀干类害虫、食叶类害虫、刺吸类害虫和螨类。为避免和减轻病虫害的发生,本文对其防治技术进行了介绍,为指导杨树病害防治提供有益借鉴。 In recent years, with the accelerating pace of ecological construction, poplar planting area expanded year by year, the formation of long-term single tree species, often lead to some pests and diseases. According to recent surveys, it is found that the most common poplar diseases are poplar black spot disease, poplar leaf rust, poplar canker disease and poplar disease. Pests are mainly borer pests, leafy insects, sucking insects and mites. In order to avoid and reduce the occurrence of pests and diseases, this paper introduces its prevention and control technology, which provides a useful reference for guiding the prevention and control of poplar diseases.
