摘要:
为解决半干旱、半湿润地区灌溉水利用率低、劳动效率低等问题，提出了一种多口水带地面节水灌溉技术，对多口水带地面节水灌溉装置进行了一系列设计、制作及试验，为地面节水灌溉技术的进一步研究与推广提供相应的数据及操作技术经验，对半干旱、半湿润地区节水灌溉新技术的发展起到积极的推进作用。
Abstract:A multiport hose ground water-saving irrigation technology was proposed to solve irrigation low efficiency and low labor efficiency problem in semiarid and semihumid areas． Through this technology, a series of design, manufacture and experiment were carried out on multiport hose ground water-saving irrigation device, which provided data and technical experience for further research and promotion of this technology． It could play a positive role in promoting development of new water-saving irrigation technology in semiarid and semihumid areas．
