嘉峪关地区属于甘肃河西走廊西部,年降水量不及100毫米,大气干旱,农田全靠祁连山雪水灌溉。小麦是我市的主要粮食作物。小麦全蚀病是近几年发现的一种危险性的小麦根病,它扩展迅速,危害严重。为了我市粮食持续增产,我们从1973年起开始调查,并与甘肃省农科院植保所在我市文殊公社联合建立基点,进行发病规律调查和防治试验,初步积累些危害、发病规律和防治办法。造成小麦枯死的病原,主要是小麦全蚀病(Ophiobolus graminis),在嘉峪关另外还有根腐菌(Helminthosporium spp.)与镰刀菌(Fusarium spp.)等。受全蚀病为害的小麦苗期长势不旺,地上部明显矮小,基部叶片渐
Jiayuguan region belongs to the west of Gansu Hexi Corridor, less than 100 mm of annual precipitation, atmospheric drought, farmland thanks to the snow Qilian irrigation. Wheat is the city’s main food crop. Total eclipse of wheat is a dangerous wheat root disease discovered in recent years. It expands rapidly and endangers seriously. In order to continue to increase grain production in our city, we started the investigation from 1973 and set up a joint base with the Plant Protection Office of Gansu Academy of Agricultural Sciences in Wenshu commune in our city to carry out investigation and prevention and control of disease incidence, and preliminarily accumulated some hazards, incidence laws and prevention measures . The pathogen causing the death of wheat is mainly Ophiobolus graminis, and there are other Helminthosporium spp. And Fusarium spp. In Jiayuguan. By the eclipses of wheat seedling growth is not prosperous, obvious dwarf above the ground, the base leaves gradually
