玉米是我州主要粮食作物之一。近年来,我地区受玉米大斑病的为害较重,特别七、八月多雨湿润年份发生更重。据调查,减产可达10％以上,巳成为玉米高产、稳产的重大阻碍。同内外多年研究工作都已证明,培育和应用抗病、丰产良种是防治大斑病的根本途径。为了选育抗病品种,我配合育种教研室,自一九七六至一九八○年院内玉米品种田,共 Corn is one of the main food crops in my state. In recent years, my area is severely damaged by the maize leaf spot, especially in rainy and wet years in August and August. According to the survey, a reduction of more than 10% has become a major obstacle to the high yield and stable yield of corn. With many years of research both inside and outside, it has been proved that cultivating and applying disease-resistant and high-yielding varieties is the fundamental way to prevent and cure large spot disease. In order to breed resistant varieties, I worked with the Breeding and Teaching Departments to grow corn fields in the hospital from 1976 to 1980
