银川引黄灌区有两千多年灌溉历史,是我国古老灌区之一,也是北方著名的稻、麦高产区之一。但很多耕地上土壤盐碱化现象严重,地下水位较高,影响生产的发展。因此研究确定适合灌区稳产高产的地下水位控制标准,对灌区当前农田基本建设、排水工程配套具有重要意义。本文采用1964年以前排水地段地下水动态与盐化春小麦地上的土壤水盐动态等方面的观测资料,对地下水控制标准作一粗浅探讨。
Yinchuan Diversion Yellow Irrigation Area has more than two thousand years of irrigation history, is one of the ancient irrigation areas in China, but also one of the famous northern rice, wheat high yield areas. However, many of the cultivated land is characterized by serious soil salinization and high groundwater level, which affects the development of production. Therefore, it is of great significance to study and determine the control standard of groundwater table that is suitable for stable and high yield in irrigated area, which is of great significance for the current farmland infrastructures and drainage projects in the irrigated area. In this paper, the use of groundwater in the drainage area before 1964 and groundwater salinity dynamics of soil water and salt dynamic observations and other aspects of the groundwater control standards for a brief discussion.
