我师塔里木垦区位于塔里木河下游,其气候特点是:寒暑变化剧烈,雨量稀少(年降水80毫米),蒸发量大,春夏常多干热风.土壤一般属轻砂壤和砂壤土,1—2米以下是砂土,整个地区都含有不同程度的钠盐(氯化钠、硫酸钠).由于近年来新开荒地面积继续扩大,大面积的洗盐和作物灌水,再加排水设备不完善,地下水位急剧上升.据塔四场52个观测井的记载:开垦前,地下水位深度一般3—5米,最深的在7米以下,有些地势较低的轮作区,地面积水已形成沼泽.
My teacher Talimu reclamation area is located in the lower reaches of the Tarim River, its climate is characterized by: severe cold and summer changes, rainfall is scarce (annual precipitation 80 mm), evaporation, spring and summer are often dry and hot air .Lands are generally light sandy loam and sandy loam, 2 meters below the sand, the entire region contains varying degrees of sodium (sodium chloride, sodium sulfate). As in recent years continue to expand the area of newly reclaimed land, large areas of salt washing and crop irrigation, coupled with imperfect drainage , The groundwater level rose sharply.According to the records of the 52 observation wells in the four towers of the tower, before the reclamation, the depth of the groundwater table is generally 3-5 meters, the deepest is less than 7 meters, and some of the terrain is low, the groundwater has formed swamp .
