测定了奎屯垦区棉花黄萎病致病类型,明确了该区棉花黄萎病发生与温、湿度等气象因子的关系;通过黄萎病抗性鉴定,表现耐病的品种(系)有13个;利用选择性培养基以新陆早35号为供试材料分析了棉花黄萎病发病与土壤中黄萎病菌微菌核数量之间的关系。获得了新陆早35号菌核含量致病的临界点。调查了生物药剂萎菌净防治棉花黄萎病的效果。
The pathogenic types of cotton Verticillium wilt were surveyed in Kuitun reclamation area. The relationship between the occurrence of cotton verticillium wilt and temperature, humidity and other meteorological factors was clarified. Thirteen cultivars (lines) showed resistance to Verticillium wilt, The relationship between the incidence of Verticillium dahliae and the number of Mycological nuclei in Verticillium dahliae in soil was analyzed by using selective culture medium Xinluzao 35 as test material. Obtained Xin Lu Zao 35 sclerotinia pathogenic critical point. Investigated the effect of biological agent wilt net prevention and control of cotton verticillium wilt.
