本文论述了沧州地区在节水灌溉发展中的经验、措施和突破性的进展。对降低管材造价,机具、管件和出水口的系列化研究作了科学的分析比较。沧州地区是河北省水资源最紧缺的地区。多年来人们在抗旱灌溉中,为减少渗漏提高水的利用率,创造了多种形式的防渗节水措施。近几年有显著节水节能效果的低压管道输水灌溉发展很快。据统计,截止1990年9月全区兴建管道灌溉工程1737.17万米,其中:砼地下管道31.68万米,硬塑地下管道76.5万米,地埋软管2.8万米,地上移动软管1626.19万米,共配套机井4.08万眼,控制灌溉面积269万亩,在我区抗旱夺丰收中发挥了重大作用。实践证明,低压管道输水灌溉是我区发展节水型灌溉的重要措施。
This article discusses the experiences, measures and breakthroughs in the development of water-saving irrigation in Cangzhou. To reduce the cost of pipe, machinery, fittings and outlet series made a scientific analysis and comparison. Cangzhou is the most scarce water resources in Hebei Province. Over the years people in drought irrigation, to reduce leakage to improve water utilization, creating a variety of forms of seepage water saving measures. In recent years, there is a significant water saving and energy saving effect of low pressure pipe water transport irrigation developed rapidly. According to statistics, by the end of September 1990, a total of 17.3717 million meters of pipeline irrigation projects have been constructed in the whole district, including 316,000 meters of concrete underground pipes, 765,000 meters of hard-plastic underground pipelines, 28,000 meters of buried hoses and 16,261,900 meters of ground moving hoses , A total of 40,800 wells supporting wells, control of irrigation area of 269 acres, drought-harvested in our region has played a significant role. Practice has proved that the low-pressure pipeline irrigation is the development of water-saving irrigation in our region an important measure.
