As a new efficient water-saving irrigation equipment, the buried automatic telescopic sprinkler system has reached the international advanced level and has significant advantages. Based on the buried automatic telescopic sprinkler system constructed the alfalfa planting demonstration area in Ningxia water-saving and effi- cient agriculture science and technology park, the construction technology and the matters needing attention were summarized and concluded from the following as- pects: excavation site survey, construction scheme design, site lofting and earth ex- cavation, pipeline installation and pressure testing, nozzle installation and pipe canal backfilling, investigation well and drain well construction, head filter system installa- tion, water power system construction, which provided guidance for construction and renovation of the sprinkler system and efficient water-saving irrigation projects. 展开更多
