关于棉花枯、黄萎病混生病株的鉴别,前人曾作过一些探索,但方法均不尽完善。通常采用常规分离镜检的方法鉴别混生病株。在实践中此方法费时、费力,结果也未必准确。即使初步鉴别出混生病株,也难将混生在一起的枯、黄萎菌分别移植出来进行纯化,作精确的鉴定。六十年代初提出的双重染色鉴别法,尚有一些问题需要澄清。在利用选择性培养基从种子和土壤中分离鉴别枯、黄萎菌的研究中,说明利用选 On the cotton withered, Verticillium wilt mixed disease identification, some have made some exploration, but the methods are not perfect. The method of routine separation microscopy is usually used to identify the mixed strains. In practice, this method is time-consuming, laborious, the result may not be accurate. Even if the initial identification of mixed strains, it is difficult to mixed together withered, Verticillium were transplanted for purification, for accurate identification. There are still some problems that need to be clarified in the double staining method proposed in the early 1960s. In the study on the separation and identification of Withered and Verticillium wilt from seed and soil using selective media,
