本文根据我国北方各地农民群众应用低压管灌系统的实践经验和典型试点研究资料,分析了近几年低压管灌系统在我国迅速发展的原因,提出在山丘区和大中型自流灌区、提水灌区发展自压式低压管灌系统的前景广阔。它将是解决我国北方缺水地区农业灌溉的节水、节能的技术措施。
Based on the practical experience and typical experimental data of low pressure pipe irrigation system applied by peasants in different parts of northern China, this paper analyzes the reasons for the rapid development of low pressure pipe irrigation system in China in recent years. It is proposed that in the hill areas and large and medium gravity irrigation areas, Irrigation area development of self-pressure low pressure pipe irrigation system has a bright future. It will be to solve the water-saving and energy-saving technical measures of agricultural irrigation in the water-scarce areas of northern China.
