在准噶尔盆地北部平原荒漠灌溉区经５年试验，总结出在土壤含有一定盐分的高水位区地下水位与紫花苜蓿根深关系的回归方程为Ｙ＝１．０４６Ｘ－０．３５５，从而确定了控制地下水位的灌溉方法，即当水位降至１ｍ左右时为适宜灌溉期，灌溉至水位上升到地表下３０ｃｍ左右即可，能避免紫花苜蓿死亡，使建立苜蓿人工草地获得成功。
After five years’ experiment in the plain desert irrigation area in the northern part of Junggar Basin, the regression equation of the relation between groundwater level and root depth of alfalfa was found to be Y = 1.046X-0.355 in the high water level area with certain salt content, Bit of irrigation methods, that is, when the water level dropped to about 1m for irrigation, irrigation to the water level rose to about 30cm below the surface can avoid alfalfa death, the establishment of alfalfa artificial grass success.
