土默特平原大小黑河灌区耕地中的盐斑地,根据其本身的特点和性状,应该采取培育土壤熟化层的办法改良。第一,大小黑河灌区耕地中的盐碱地主要是呈斑状分布,一般均处在较低的碟形洼地中,排水困难,而且水资源及供水时期均满足不了冲洗用水的需要,所以水利措施改良一时还难以上马。 According to its own characteristics and traits, the saline land in the cultivated land in the Heihe Irrigation Area of ​​the Tumote Plain should be improved by cultivating the soil maturing layer. First, the salinity-alkaline soil in cultivated land in the Heihe Irrigation Area is mainly in a patchy distribution. Generally, it is in a low disc-shaped depression and has difficult drainage. Moreover, the water resources and water supply period can not meet the needs of flushing water, so the water conservancy measures are improved temporarily It is difficult to launch.
