棉花桔、黄萎病是国内植物检疫对缘,是一种毁灭性的病害,一般可使棉花减产20～30%,严重的造成绝收,对棉花产量影响很大.近年来我省南阳、安阳、扶沟、荥阳、尉氏等县,采用的地膜覆盖植棉新技术,经实践证明是一项防病增产措施.睢县唐庄公社1981年棉花枯、黄萎病发病株率为26%,1982年采用地膜覆盖,发病株率下降到1.1%,而不覆盖地膜的发病率为 Cotton tangerine, Verticillium wilt is the phytosanitary on the edge of the country, is a devastating disease, the general cotton yield can be reduced by 20 to 30%, resulting in serious failure to yield a great impact on cotton yield in recent years, Nanyang in our province, Anyang , Fugou, Mianyang, Weishi and other counties, the use of plastic film mulching cotton new technology, proved to be a disease prevention and yield stimulation measures.Xiongxian Tangzhuang commune in 1981 cotton withered, Verticillium wilt incidence rate of 26% , The use of mulching in 1982, the incidence of plant rate dropped to 1.1%, but not covered the incidence of plastic film
