低压管道输水节水灌溉技术在石头河灌区的运用

Application of Water-saving Irrigation Technique of Water Conveyance with Low-pressure Pipe in Shitouhe Irrigation Area

针对低压管道输水节水灌溉技术在石头河灌区的应用,针对自然高差较大,且属清水灌溉,适合低压管道输水灌溉这一特点,从系统设计、设备选型、灌溉管理等方面对低压管道输水节水灌溉技术进行了全面系统的介绍。通过近年的示范推广,证明该项技术具有节水、省地、省工和工程造价低、施工简便、管理方便及工程寿命长、增产效益显著等多种优势。该技术的应用对缓解水资源危机,提高农业生产水利设施条件,改善农业生态环境,增加农民收入发挥了重要作用。

According to the application of the water-saving irrigation technique of water conveyance with low-pressure pipe in Shitouhe Irrigation Area,and based on the characteristics such as large height difference,clear water irrigation and being suitable for the water-conveyance irrigation with low-pressure pipe,the water-saving irrigation technique with low-pressure pipe is introduced overally and systematically in the aspects such as system design,equipment selection,irrigation management and so on.Through the demonstration and popularization in recent years,it is proved that this techuique has more advantages such as saving water,land and labour,and lower cost,simple construction,simple management as well as long life-span,remarkable benefit,and so on.The application of the technique has played the important part in relaxing the crisis of water resources,raising the conditions of agriculture and water conservancy,improving agricultural and ecological environment and increasing peasent＇s receipts.
