内蒙古自治区水资源贫乏,扩大灌溉面积的主要途径是节约用水全区年灌溉引水量近95亿立方米,若能将现有渠系利用系数0.4提高到0.7,则可扩大面积100万亩.节约用水的一条重要措施就是渠道衬砌,但我区气倏寒冷,渠道衬砌遭受严重破坏.为解决这一问题,我们在亦峰市哲里木盟和河套灌区,就防冻害问题作了一些探索,取得了几项较为
Inner Mongolia Autonomous Region is short of water resources, the main way to expand irrigation area is to save water throughout the region’s annual irrigation water diversion of nearly 9.5 billion cubic meters, if the existing canal utilization factor of 0.4 raised to 0.7, you can expand the area of 100 hectares. An important measure of water use is channel lining, but the gas in our district is cold, and the lining of the channel has suffered serious damage.In order to solve this problem, we made some explorations on the issue of frost damage in Zheli League and Hetao Irrigation District in Yifeng City, Made a few more
