微喷带是适宜辽宁西部地区补充灌溉的节水灌溉技术，为了提高微喷带的适用性，文章通过与滴灌（ DI）和漫灌（ FI）做对比试验研究了玉米微喷带灌溉（ SI）的效果。试验结果表明SI较FI节水35％，灌溉次数为DI处理的1／2；SI和DI较FI对植株营养生长有一定抑制作用，但均促进了生殖生长，获得较多的穗行数和行粒数；SI节水增产效果低于DI，仍较FI玉米产量和WUE分别提高1.1％和19.0％。因此，微喷带灌溉可用于玉米节水灌溉，尤其在滴灌等设备使用效率低的补充灌溉地区，微喷带是适宜的选择。

Spray-hose irrigation is a new kind of water saving irrigation method suited for supplementary irrigation in semi-arid region of western Liaoning province.In order to promote its usability,experimental study of the effects on maize of spray-hose irrigation ( SI ) was conducted in this paper, and drip irrigation ( DI ) and furrow irrigation ( FI ) were carried as checks.The results showed that SI saved 35%water of FI and have times for irrigation of DI;the water saving irrigation methods of SI and FI restrained the vegetative growth of maize,but promoted its reproductive growth,and thus,got more ear rows and line grain numbers;though the amount of water saved and yield increased of SI were less than DI,they were still larger than FI,its yield and WUE increased 1.1%and 19.0%,separately.Therefore, it was estimated that maize could be irrigated by spray-hose, especially in the region where water irrigated as a supplement and the rates of utilization of irrigation equipments were very low,sprayhose could be a reasonable choose.
