吉林省长岭县是全国重点产粮大县之一。玉米播种面积占总耕地面积的70％以上,是左右粮食产量的骨干品种。近两年来,在探索玉米茎基腐病防治方面,我们做了大量的试验工作,收到了很好的防治效果,1995年全县2,000多公顷玉米得到了有效的防治,挽回了经济损失近500万元。 Changling County, Jilin Province, is one of the key grain-producing counties in the country. The sown area of ​​maize accounts for more than 70% of the total cultivated land, which is the key variety of grain output. In the past two years, we have done a lot of experiments in exploring the prevention and treatment of corn stem-based rots and have received good control effects. In 1995, more than 2,000 hectares of corn in the county were effectively controlled and the economic loss was nearly 500 Million.
