为明确地膜覆盖对棉花枯、黄萎病田间发病的影响,进行了地膜覆盖和露地直播田间对比试验。结果显示,在多雨、气候适宜发病年份,地膜覆盖栽培棉田的枯、黄萎病发病程度明显重于露地直播田。提出了老棉区实行露地直播以控制、减轻棉枯、黄萎病发生的技术措施。 In order to clarify the impact of plastic film mulching on the incidence of cotton withered and Verticillium wilt, a field experiment was conducted to study the effects of plastic film mulching and direct seeding. The results showed that the incidence of withered and Verticillium wilt in cotton field mulched with plastic film mulching was obviously heavier than that in open field in rainy and climatic prone years. Proposed the implementation of open area live cotton to control, reduce the cotton wilt, Verticillium wilt occurred technical measures.
