刺果藤(Sicyos angulatus L.)以前我国仅在台湾、大连和青岛有发生记载。北京市2010年在海淀区温泉镇山区林地首次发现刺果藤危害林木。2013年在延庆、密云、海淀3个区县9个乡(镇)大面积发生危害,发生面积274 hm2,并已从山区林地扩展到大田、果园等地。北京市植保系统高度重视,并进行了有效铲除。但由于土壤中难以彻底灭除的积存种子以及贸易、旅游、交通等影响,刺果藤仍有蔓延的危险。必须高度重视,加强检疫监测,一经发现,立即彻底铲除。
Sarcodon (Sicyos angulatus L.) Previously, only recorded in Taiwan, Dalian and Qingdao. Beijing in 2010 in the town of Haidian District, Wenquan spring forest was found for the first time thorn fruit vine damage trees. In 2013, 9 townships (towns) in Yanqing, Miyun and Haidian districts and counties were damaged in a large area with an area of 274 hectares (2 hectares) and expanded from mountainous areas to Daejeon and orchards. Plant protection system in Beijing attaches great importance to and effective eradication. However, because of the accumulation of seeds in the soil, which is difficult to eradicate, and the impact of trade, tourism and transportation, there is still a danger that Spurgeon will spread. We must attach great importance to strengthening quarantine and surveillance and, once discovered, completely and immediately eliminate it.
