苦水灌溉对于发展干旱、半干旱地区农牧业生产具有重大意义。宁夏南部山区干旱少雨,河沟、水库以及地下水中,含有大量盐分,一般在3～6克/升以上,有的甚至高达10克/升。为了发展农业生产,改变干旱面貌,山区人民十多年来利用这些高含盐量的苦水进行农田灌溉,通过长时间的生产斗争和科学实验,取得了较丰富的正反两方面的经验。
Bitter-water irrigation is of great significance for the development of agriculture and animal husbandry in arid and semi-arid areas. In the southern part of Ningxia, there is a lot of salt in arid areas, dry valleys, reservoirs and groundwater, generally above 3 to 6 g / l, and some even up to 10 g / l. In order to develop agricultural production and change the landscape of drought, people in mountainous areas have used these high-salt and bitter waters for farmland irrigation for more than a decade. Through long-time productive struggles and scientific experiments, they have gained a wealth of positive and negative experiences.
