灌区水盐动态是灌区各种自然因素和人为活动效果的综合反映,是检验技术措施和客观效果的依据、因此在讨论河套灌区灌溉农业问题时,必须首先研讨土壤和潜水水盐动态问题。但由于河套灌区目前尚无专门的观察研究机构从事长期系统研究,原五原土套改良试验站和水文地质站,在六十年代初虽作了很多工作,累计大量资料,但后来下马中断,失去与近期灌区资料的连续性,有的资料在文化革命中又多失散,而近些年来河套灌区各地试验站又断
Therefore, when discussing irrigation agriculture in Hetao Irrigation District, we must first discuss the dynamic issue of soil and sub-surface water and salt. However, as there is no long-term systematic study conducted by the specialized observation and research institutes in the Hetao Irrigation District, the original Fifth Pilot Station and hydrogeological station made a lot of work in the early 1960s with a large amount of data accumulated. However, Lost and the recent irrigation data continuity, and some information in the cultural revolution and more lost, and in recent years the Hetao irrigation area test stations and broken
