黄萎病圃是研究黄萎病和抗病育种不可缺少的基本条件。本所应用接菌棉籽随棉种播下,连续二年收效甚微。远途运来感病棉秸又恐传播病害,故用当地诱发感病棉秸接种病圃。黄萎病是棉花生产上的大敌,根据唐山、湖北等地报道,棉花黄萎病所造成的损失与发病程度和发病时期有关。唯恐生长前期对棉株注射黄萎病菌,影响产量过大,造成经济损失过巨,因此采用中后期接种,籍此机会也观察发病对产量的影响。 Verticillium wilt is an indispensable basic condition for studying Verticillium wilt and disease-resistant breeding. The application of cotton inoculation with cotton sowing, with little success for two years. Long-distance transport of susceptible cotton straw and spread of fear of disease, it is induced locally infected cotton inoculation disease nursery. Verticillium wilt is the enemy of cotton production. According to reports from Tangshan and Hubei, the losses caused by Verticillium dahliae are related to the degree of the disease and the onset of the disease. Fear of early growth of cotton plants infected with Verticillium wilt bacteria, affecting the production is too large, resulting in huge economic losses, so the use of late inoculation, take this opportunity to observe the incidence of the impact on the yield.
