近年,蔬菜保护地生产发展迅速,实现了周年多种、多茬蔬菜栽培。但是,与此同时也为根瘤线虫的转主寄生、连续繁殖提供了适宜的环境条件。北京近郊的大型温室和固定大棚等曾有根瘤线虫病发生,造成减产30%～60%。长江流域以南的湖北、贵州、云南、广东、广西等地,此病的发生也较为普遍。有些地方可减产80%以上。一、常见的蔬菜根瘤线虫根瘤线虫用肉眼难以观察,需借助于显微镜。雌雄幼虫为线形,成虫形态

In recent years, the rapid development of vegetable production has achieved many anniversaries and more vegetable cultivation. However, at the same time, it also provided suitable environmental conditions for the host parasitism and continuous breeding of root-knot nematode. Large-scale greenhouses and fixed greenhouses in the suburbs of Beijing once had root-knot nematodes disease, resulting in a 30% -60% reduction in production. South of the Yangtze River in Hubei, Guizhou, Yunnan, Guangdong, Guangxi and other places, the occurrence of the disease is also more common. In some places it can cut more than 80%. First, the common root-knot nematode root canal nematode with the naked eye is difficult to observe, with the help of a microscope. Male and female larvae for linear, adult morphology
