推广抗病品种是防治棉花枯黄萎病的一种经济有效措施。而抗病育种需要建立一个发病重且均匀的病圃。随着科研工作的深入对病圃的需要不仅是几分、几亩,而是十几亩、甚至几十亩的面积。为了有利于棉花抗枯萎病育种工作的开展,枯萎菌种的人工培养繁殖方法必须有所改进。过去,棉花枯萎菌的扩大繁殖,一般多采用麦粒砂培养基。因其以小麦为主要成分,使菌种的大量繁殖受到一定的限制;苏联有人用液体培养基培养成枯萎菌液,进行接种,但使用不便,效果也不理想;西北农 Popularization of disease-resistant varieties is a cost-effective measure to prevent and control cotton yellow-wilt disease. Disease-resistant breeding needs to establish a heavy and uniform disease nursery. With the deepening of scientific research on the needs of the nursery is not only a few, a few acres, but more than ten acres, or even dozens of acres of area. In order to facilitate the development of cotton breeding against Fusarium Wilt, the methods of artificial cultivation and propagation of Fusarium wilt must be improved. In the past, the expansion of cotton Fusarium multiplication, the general use of wheat sand media. Because of its wheat as the main component, so that the multiplication of strains of bacteria subject to certain restrictions; some people in the Soviet Union cultured with liquid medium into Fusarium bacteria for vaccination, but the inconvenience, the effect is not satisfactory; Northwest farmers
