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,所以,搞好玉米病虫害的有效防治工作就显得十分重要。近两年来,在探索玉米茎基腐病防治工作中,我们做了大量试验工作,取得了良好效果。1995年全县2,000多公顷玉米得到了有效防治,挽回了经济损失500万元左右。 Changling County, Jilin Province, is one of the key grain-producing counties in the country. Maize sown area accounts for more than 70% of the total cultivated area, is about the backbone of grain yield varieties, so do a good job of corn pests and diseases prevention and control work is very important. In the past two years, we have done a lot of experiments in exploring the prevention and treatment of corn stem-base rot and have achieved good results. In 1995 more than 2,000 hectares of corn in the county have been effectively controlled and saved about 5 million yuan of economic losses.
