【摘要】：针对韩墩引黄灌区实施浑水灌溉后大量泥沙入田的现实情况,为了预控土壤沙化,实现田间科学利用泥沙,精准改良土壤,研究提出了沙化参数的概念,以表征引黄灌区浑水灌溉可能造成土壤沙化的程度;提出了测土配沙改良土壤运行模式及科学配沙工程技术措施。其中,科学配沙工程技术措施包括两种:一是为改良砂质土壤,增加砂质土壤的保水性,利用泥沙沿垂线下粗上细的分布规律,设计了分层取水取沙的工程技术措施;二是为有效改善黏质土壤的透气性能,提出了导沙技术措施。
[Abstract]:In order to predict soil desertification, realize scientific utilization of sediment and improve soil accurately in order to control soil desertification, the concept of desertification parameters is put forward in order to control soil desertification in order to control soil desertification, and to characterize the degree of soil desertification in the irrigation area of Yellow River irrigation area. There are two kinds of technical measures for scientific sand distribution engineering. One is to improve the sand soil, increase the water retention of sandy soil, and make use of the coarse and fine distribution law of sediment along the vertical line, and design the engineering technology of stratified water intake and sand extraction; two is to improve the permeability of the clay soil effectively, The technical measures for sand guide are given.
