摘　　要：以“白燕一号”燕麦品种为试材，采取小区对比与多点调查的方法，研究了播期、播量、施肥以及耕层土壤盐碱含量对燕麦生育及产量的影响。结果表明：（1）随着播期的推迟，各处理燕麦从播种到出苗的天数以及生育期天数逐渐缩短，处理B3单产260．4kg／667m^2，比B1、B2、B4、B5处理分别增产了15．5％、6．9％、4．6％、10．O％。（2）播量以处理c3的8．0kg／667m^2为宜，其单产372．0kg／667m^2，比c1、c2、c4、c5处理分别增产了9．3％、5．O％、5．4％、16．4％。（3）在施肥量相同的前提下，氮磷全部作基肥，可获得产量250kg／667m^2；若以氮肥的40％作蘖肥施入可使燕麦略有增产；增施抗盐碱剂5．0～10．0kg／667m^2，可使燕麦增产12．5％～17．1％。（4）燕麦遭受盐碱危害，因生长发育受到抑制而减产，其株高、千粒重明显降低，单位面积收获穗数、铃数、粒数明显减少。The strain of Yumi 2 was used as a material to study the grain yield and water use efficiency of proso millet under different water-saving treatments in standstorm area along the Great Wall. The results show that the water saving ways may improve field catchment and water retention, increase soil water content, reduce water consumption amount and water consumption intensity. The grain yield of proso millet with film mulching on ridge and double furrows was largest, reaching 6 927.43 kg/hm2 and increasing by 40% compared to CK, while its water use efficiency was 17.22 kg/（hm2＂ mm）, increasing by 60.19 %. Film mulching on ridge and double furrowss may improve field catchment and water retention, and increase grain yield and water use efficiency.
