新疆地处我国西北内陆,年降雨量200毫米以下,地面水相当缺乏,而一些地区却有丰富的地下水。但由于长期使用不当,造成土地大片盐碱。如何解决这个问题?以下,就我区利用地下水长观资料,进行土地盐碱预测、预报和控制,淡几点体会。我区4800万亩农田中,不同程度盐渍地占三分之一,严重影响区内农业发展,因此,进行盐碱地改良势在必行。
Xinjiang is located in the hinterland of northwestern China, with an annual rainfall of less than 200 millimeters and a considerable shortage of surface water. However, some areas have abundant groundwater. However, due to improper use for a long time, resulting in land salinities. How to solve this problem? The following, the use of long-term groundwater information in our area, the land salinization forecast, forecast and control, a few short experience. Among 48 million mu of farmland in our district, saline land occupies one third of the farmland, which seriously affects the development of agriculture in the area. Therefore, it is imperative to carry out the improvement of saline-alkali land.
