在新疆地区,盐渍土面积根大,这与环境条件水文状况的影响有关。乌鲁木齐垦区,全年降水约130毫米,蒸发量为2,000毫米,大於水量15倍。在作物生长期间(5—9月),蒸发量占全年总量的90％。由於地下水位较高(一般是1.5—2公尺),土壤含盐重,所以土壤中的盐分随毛细管水上升,累积於表层。加上土壤缺乏有机质,结构不良,耕作粗放,所以盐渍化情况严重。每年有根大面积由於土壤溶液浓度大,地面反碱,造成严重的缺苗损失。即或免强出苗,但生长矮小,产量很低。因此,明确对於什麽样的盐碱地可以耕种,种什麽作物?或什麽样的盐碱地不能
In Xinjiang, the area of saline soil is large, which is related to the hydrological condition of the environment. Urumqi reclamation area, the annual precipitation of about 130 mm, evaporation of 2,000 mm, 15 times greater than the water. During crop growth (May-September), evaporation accounts for 90% of the total for the year. Due to the high groundwater level (typically 1.5-2 meters), the salt content in the soil increases with capillary water and accumulates on the surface. Coupled with the lack of soil organic matter, poor structure, extensive farming, so salinization is serious. Every year, a large area due to the concentration of soil solution, the ground anti-alkali, causing serious lack of seedlings. Namely or strong emergence, but the growth of short, low yield. Therefore, it is not clear what kind of crop can be cultivated or what kind of saline-alkali soil can not be cultivated
