摘要
在长白山保护区天然针阔混交林和张广才岭地区红松人工林内,设立5个样地,采集蜜环菌样本331号。利用体细胞非亲和性的试验方法,鉴定出东北地区林木病原菌奥氏蜜环菌在林间的遗传体密度较低,是以菌索的形式存在,并为主要传播方式。在防治中应以切断病原菌的土壤传播为主要原则。
In the natural coniferous-broad-mix forest of the Changbai Mountain and the Pinus koraiensis plantation of the Zhangguangcai Mountain range, 5 plots were set up, 331 Armillaria specimens were collected. Somatic incompatibility test showed that the density of Armillaria ostoyae genet was lower in the northeast forest of the Changbai Mountain, and it existed in rhizomorphs which was main dissmination mode. The main principle of prevention should be to stop the dissmination of the pathogeny-fungi in soil.
