在设计灌水量(3750 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108371 kg/hm2,较对照大水漫灌(7500 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103231 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.
在設計灌水量(3750 m3/hm2)條件下,採用寬帶微噴式、滴灌兩種微灌管帶,觀察瞭不同鋪設方式對洋蔥的影響,結果錶明,以寬帶微噴式管帶每膜鋪設2行處理的洋蔥摺閤產量最高,為108371 kg/hm2,較對照大水漫灌(7500 m3/hm2)增產7.94%,灌溉水利用效率和灌溉水效益分彆達28.90 kg/m3和8.7元/m3;其次是滴灌管帶每膜鋪設3行處理,摺閤產量為103231 kg/hm2,較對照大水漫灌增產2.82%,灌溉水利用效率和灌溉水效益分彆為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.
