摘要
甘肃素有"千年药乡""天然药库"等美称,全省有中药材资源2540种,大宗药材30多种,黄芪(Astragalus menbranaceus Bge.)作为"十大陇药"之一,黄(红)芪种植面积达2.8万hm^(2),占全国的40%。黄芪补脾益气,具有生血摄血,增强免疫功能、保肝、利尿、抗衰老、抗应激、降压的功能。随着我省黄芪人工栽培面积的逐年扩大,生长环境的改变和病原菌不断积累,黄芪病害已成为制约其产量和品质的重要因素。
Astragalus membranaceus is one of the"ten most effective drugs".A new fungal disease of A.mongholicus was found in Dingxi,Gansu from 2017 to 2019.The symptoms in the field were premature death and the leaves did not fall off,the whole plant or its one side was ill,and the root vascular bundle became brown and necrosis.In order to identify the disease and its pathogenic fungi,the pathogen was isolated by tissue isolation method and identified by culture character,morphology,and rDNA-ITS.The result showed that the pathogen was Verticillium dahliae.This was the first report on A.verticillium and its pathogenic fungus,which provides a theoretical basis for controlling this disease in production.
