摘要
改性PE软管是近几年在我国北方地区发展起来的低压管道灌溉中广泛使用的一种输水管材.本文对改性PE软管输水性能、特点进行理论分析和试验研究,并参照我国北方地区,如山东、河南、河北的有关经验给出常用规格的改性PE软管在低压输水灌溉应用中的主要水力要素参数改性PE软管低压输水性能一览表,供各地从事低压输水灌溉的人员参考使用.
The IFPP is used widely to convey water in the low pressure pipe irrigation system which has been developed in the north districts of China in recent years. The conveyance characteristics of the IFPP have been tested and studied. This paper, referring to the irrigation practice in Shandong, Henan and Hebei Provinces, indroduces the main results of the test and study, which can be applied to the low pressure pipe irrigation.
