在设计灌水量(3 750 m3/hm2)条件下，采用宽带微喷式、滴灌两种微灌管带，观察了不同铺设方式对洋葱的影响，结果表明，以宽带微喷式管带每膜铺设2行处理的洋葱折合产量最高，为108 371 kg/hm2，较对照大水漫灌(7 500 m3/hm2)增产7.94%，灌溉水利用效率和灌溉水效益分别达28.90 kg/m3和8.7元/m3；其次是滴灌管带每膜铺设3行处理，折合产量为103 231 kg/hm2，较对照大水漫灌增产2.82%，灌溉水利用效率和灌溉水效益分别为27.53 kg/m3和8.3元/m3。

The two kinds of micro-irrigation pipe belt tapes of broadband micro-sprinkling and drip irrigation was used under the condition of design irrigation amount 3 750 m3/hm2， and the effect of mode of micro-irrigation pipe laying on onion cultivation was observed . The results showed that the treatment of the highest yield of onion is broadband micro-sprinkling pipe laying per film two rows， which is 108 371 kg/hm2， yield than flood irrigation(7 500 m3/hm2) 7.94%， the water use efficiency and irrigation benefit is 28.90 kg/m3 and 8.7 yuan/m3； the second yield was 103 231 kg/hm2 of drip irrigation pipe laying per film three rows， which higher than flood irrigation 2.82%， and the water use efficiency and irrigation benefit is 27.53 kg/m3 and 8.3 yuan/m3.
