摘　　要：膜上灌是一种新型地面灌溉技术,具有节水和增产的双重效应。为此,在河西内陆灌区对春小麦和玉米进行了平铺打埂膜上灌水技术试验研究,以期为膜上灌技术的大面积推广应用提供技术指导和理论依据。通过试验,得出膜上灌春小麦和玉米的地膜覆盖技术要点、灌水技术要点和全生育期适宜灌水量。其中,膜上灌春小麦在全生育期内进行4次灌溉,膜上灌玉米全生育期内进行5次灌溉。同时,也得出了不同作物各生长期的灌水定额。Film hole irrigation is a new type of border irrigation technology and has double effects of water-saving and yield-increasing. The experiment of irrigation technology of spring wheat and maize under film hole irrigation were conducted in the Inland Irrigation District of Hexi. Thus technique supervises and scientific basis were offered for the comprehensive popularization and application of film hole irrigation. The experiment discovered some keystones of plastic film mulching and irrigating, and fitting irrigation quota in whole growth period. As a result it was irrigated four times in the whole growth period of spring wheat. As such it was irrigated five times in the whole growth period of maize.
