摘要
我国进入20世纪80年代以来,水资源日益紧缺,低压管道灌溉技术在农业生产中开始迅速发展。但由于技术、设备等原因,在华北的一些井灌区,虽然使用了管道输水技术,但仍然采用普通灌溉技术,致使节水效果不明显。分析了管道输水的优势,并讨论了其与优化的灌溉技术相结合的制约因素与前景。
Since the 80＇s, there is urgent lack of the water resource in our country. The low-pressure pipeline irrigation technique developed rapidly in agriculture. Because lack of the technique and equipments, some well-irrigated regions in Northern China, although have used the pipeline system were still use the common irrigation technique, cause the water saving not obvious. This paper analyzes the advantage of the low-pressure pipeline system, and discussed the limited factors and the foreground when it combined with the optimized irrigation technique.
