管道灌溉包括地面软管系统与地下输水系统,是利用管道系统把低压水流送入田间。它适用于井灌区,也适用抽水站与山丘自流灌区。对于不同作物、土壤和水量大小均能全适。从多年运用情况来看,在水资源紧缺、连续干旱、地面条件差的情况下,发展低压管道,效果十分 Pipeline irrigation, including the ground hose system and underground water delivery system, is the use of pipelines to send low-pressure water flow into the field. It is suitable for well irrigation area, but also for pumping station and hill gravity irrigation area. For different crops, soil and water size can be fully adapted. Judging from many years of application, in the case of water shortage, continuous drought and poor ground conditions, the development of low-pressure pipelines has achieved very good results
