中文摘要	为了研究垄膜沟灌系统下不同灌水量对河套灌区土壤水盐运移规律及春玉米生长特性的影响,于2019年410月在河套灌区曙光试验站开展田间试验,通过布设5个典型灌水量(T1,200 mm;T2,275 mm;T3,350 mm;T4,425 mm;T5,500 mm),深入研究垄膜沟灌土壤水盐运移特征及其对春玉米产量和水分利用效率(WUE)的影响,尝试寻求轻度盐渍化农田的垄膜沟灌适宜灌水量。结果表明:T4与T5处理0120 cm土层的土壤贮水量接近,T5处理的玉米耗水量显著高于其他处理。T1~T5处理垄上平均储盐量分别为48.37,26.84,19.34,21.38,22.79t/hm~2。T1、T2和T5处理垄体储盐量较播种前分别增加27.33,1.54,5.88 t/hm~2,T3和T4分别减少10.04,3.42 t/hm~2,积盐量呈先减少后增加的V形变化;200,275 mm灌水量下土壤严重缺水,储盐量高,350 mm处理的土壤水盐环境适宜,WUE最高,且产量与T4和T5处理无显著差异,425,500 mm的深层渗漏大,积盐量有逐渐升高的趋势。因此,在引黄水量减少前提下,河套灌区使用垄膜沟灌350 mm的灌水量可达到节水控盐增产的目标。
英文摘要	In order to explore the effect of different irrigation amount on soil water and salt transport and growth characteristics of Spring Maize in Hetao Irrigation District(HID)under ridge with film mulchingfurrow irrigation system,field experiments were carried out in Shuguang experimental station of HID from April to October,2019.Five typical irrigation amounts(T1:200 mm,T2:275 mm,T3:350 mm,T4:425 mm,T5:500 mm)were arranged to study the characteristics of soil water and salt transport under ridge with film mulching-furrow irrigation and its effects on yield and water use efficiency(WUE)of spring maize.The results showed that the soil water storage of 0120 cm soil layer in T4 and T5 treatments was close,and the water consumption of maize in T5 treatment was significantly higher than that in other treatments.The average salt storage in T1~T5 treatments were 48.37,26.84,19.34,21.38,and 22.79t/hm~2,respectively.The salt storage quantity of T1,T2,and T5 treatments increased by 27.33,1.54,and 5.88 t/hm~2 respectively,and T3 and T4 decreased by 10.04 and 3.42 t/hm~2 so that the salt accumulation showed a" V-shaped" change.With the increase of irrigation amount,WUE first increased and then decreased,and the yield increased first and then stabilized.Under the irrigation amount of 200 mm and 275 mm,the soil was seriously short of water,and the salt storage was high.The soil water and salt environment of 350 mm treatment was suitable,where the yield and water use efficiency were high,and the deep layer leakage of 425 and 500 mm was large,and the salt storage quantity tended to increase gradually.Therefore,on the premise of reducing the amount of water diversion from the Yellow River,the irrigation amount of 350 mm under ridge with film mulching-furrow irrigation can achieve the goal of water saving,salt control and yield increase in HID.
