摘要
１９９２～１９９３年，我们在河南省内黄县设点系统调查了纯作春棉、麦套春棉的黄萎病发生消长情况，结果表明，麦套春棉与纯作春棉相比，发生始期约迟３天，前期发展缓慢，７月２０日前后形成第一发病高峰（与纯作春棉一致），以后发展减缓，隐症期无或不明显，８月２０～３０日形成第二个发病高峰。
In 1992～1993,systematic investigations showed that the occurrence of cotton Ver-ticillium wilt in wheat-cotton double-cropping field was 3 days later and its development inearly stage was slower than that in monocrop field,the first occurrencing peak were formed onJuly 20～30th, after that,the developing of cotton Verticillium wilt was slowly and the stageof concealment was not clear or non,the secondary occurrencing peak were formed on August20～30th.
