中文摘要	在民勤沙漠绿洲进行了洋葱膜下滴灌灌溉试验研究,结果表明:膜下滴灌适当减少灌水可以促使洋葱更多的利用土壤底墒,灌水相对较少的处理T2底墒利用率最高,分别比T1、T3、对照CK高10.73%、9.85%和9.92%。膜下滴灌不同灌水处理以灌水最多的T3洋葱产量最高,水分利用效率也最高;灌水最多的常规灌溉CK水分利用效率最低,分别比T1、T2、T3低35.28%、55.21%、58.79%。膜下滴灌条件下适当增加灌水量在一定程度上可增加洋葱产量,当灌水量在一定范围内,洋葱产量和水分利用效率均会显著提高。
英文摘要	Experimental study was conducted in arid environment of Minqin desert oasis to evaluate the effect of drip irrigation under mulch on soil moisture and onion yield. There were three treatments of drip irrigat ion under mulch and a CK of small border irrigation with different irrigation quotas (T_1: 2 490 m~3/ hm~2, T_2: 3 030 m~3/ hm~2, T_3: 3 570 m~3/ hm~2 and CK: 8 100 m~3/ hm~2) in the whole growing season of onion; and each treatment distributed different irrigation water amount in various growing stages. The result indicated that the highest use of soil moisture was obtained in T_2 with the relative lower growing season irrigation, and its soil moisture use in 0~ 60 cm soil layer was higher than T_1, T_3 and CK by 10. 73%, 9. 85% and 9. 92% respectively. The highest yield and the highest water use efficiency were obtained in T_3. The lowest water use efficiency was obtained in CK, which was lower than in T_1, T_2 and T_3 by 35. 28%, 55. 21% and 58. 79% respectively. So proper increase of irrigation amount on drip irrigation under mulch can improve yield and WUE in Minqin desert oasis.
