东干渠为呼图壁河下游东河水库放水干渠,担负芳草湖总场四、五、六分场及总场直属单位的灌溉引水任务。该灌区规划面积60万亩,其中可耕地43.8万亩,目前灌溉面积为12—15万亩。 根据总场气象站1962—1980年资料,历年最高气温为43.8℃,最低为-41.9℃,多年平均气温为6.2℃,多年负温最早开始于10月,最晚截止于3月,多年负温平均天数127天,冻结指数为1455度·日。历年最大降水量157mm,最小64mm,平均降水量114mm,多年平均蒸发量1819mm。干渠沿线大部分为砂壤土及砂土。土壤一般从11月10日开始结冻,第二年3月10日解冻,最大冻深103cm。地下水埋深150—250cm。
The trunk canal of the East Hutubi River Diversion Canal for the East River Diversion Canal, responsible for the grass Lake total field four, five, six sub-field and the total field units directly under the irrigation and water diversion task. The planned area of the irrigated area is 600,000 mu, of which 438,000 mu are arable land. Currently, the irrigated area is 12-15 mu. According to the total weather station data from 1962-1980, the highest temperature over the years was 43.8 ℃, the lowest -41.9 ℃, multi-year average temperature of 6.2 ℃, many years negative earliest began in October, the latest deadline in March, many years negative temperature The average number of days is 127 days, freezing index is 1455 degrees day. Over the years the maximum rainfall of 157mm, the smallest 64mm, the average rainfall of 114mm, the average annual evaporation of 1819mm. Most of the main canal along the canal are sandy loam and sand. The soil generally starts to freeze from November 10, the second is thawed on March 10, and the maximum deep freezing depth is 103cm. Groundwater depth of 150-250cm.
