摘　　要：针对地埋式滴灌这一新兴高效节水技术在民勤绿洲推广应用中存在的技术难点,从滴头流量选择、滴灌带埋设深度、铺设间距三方面开展试验研究,分析了生育期土壤水分变化情况及玉米穗物理指标、产量,提出了适合民勤绿洲生产实际的地埋式滴灌技术参数,解决了地埋式滴灌推广应用中的实际问题,提高了水资源利用效率,节约了有限的水资源,为保护民勤绿洲生态环境不再恶化起到了积极的作用。In view of the technical difficulties of subsurface drip irrigation,which is an emerging highly efficient and water-saving technique in the popularization and application of Minqin Oasis. The experiment and research are carried out from three aspects ： dripper flow selection,drip irrigation depth and laying spacing. The changes of soil moisture the physical index and yield of corn ear are analyzed,and the technical parameters of buried drip irrigation suitable for the actual production of Minqin Oasis has been put forward. The practical problems in the popularization and application of subsurface drip irrigation has been solved. The utilization efficiency of water resources and has been improved and limited water resources has been saved to protect Minqin Oasis ecological environment from deteriorating.
