棉花黄萎病是我省棉花生产上仅次于枯萎病的第二大病害。近10年,此病已蔓延及徐州、盐城、南通和苏州等市的30个县(市),影响了棉花的产量和纤维品质。“六五”期间,全省组织了协作攻关研究,采取了综合防治措施,在一定程度上控制了病区的蔓延速度。但由于棉花黄萎病寄主范围广,传播途径多,因此仍有扩大蔓延的趋势。了解并掌握黄萎病蔓延扩展趋势,对于调整抗病育种目标,进一步加强综合防治措施均具有指导意义。要做到这一点,必须把以经验为基础的判断,同运用科学的理论和方法对棉花黄萎病蔓延扩展趋势作出定量的预测结合起来。
Verticillium wilt is the second largest disease of cotton in our province after wilt disease. In the recent 10 years, the disease has spread and 30 counties (cities) in Xuzhou, Yancheng, Nantong and Suzhou have affected the yield and fiber quality of cotton. During the “Sixth Five-Year Plan” period, the province organized a collaborative research project and adopted comprehensive prevention and control measures, to a certain extent, to control the spread of the ward. However, due to the wide range of host hosts of cotton Verticillium wilt and the wide range of routes of transmission, there is still a tendency to expand and spread. Understanding and mastering the spreading trend of Verticillium wilt will be instructive for adjusting the goal of disease-resistant breeding and further strengthening the comprehensive prevention and treatment measures. To do this, it is necessary to combine experience-based judgment with the quantitative prediction of the spread of the spread of Verticillium dahliae using scientific theories and methods.
