摘　　要：以春小麦垄作沟灌入渗规律试验和其水流运动研究为基础,通过田间灌溉实验,分析不同耕作技术参数(垄宽、沟深、沟底宽、垄坡)对春小麦生长指标和产量的影响。结果表明:在河西走廊灌区垄宽40cm、沟深15cm、沟底宽15cm、坡度1:1的参数组合为垄作春小麦的最优组合模式,与垄宽30cm(T1)和50cm(T3)相比,产量增加了10.4%和10.84%;与沟底宽0cm(T5)和10cm(T6)相比,产量增加了15.89%和8.78%;与沟深20cm(T4)相比,产量增加了15.7%。Based on the studies on infiltration and water movement with the ridge furrow irrigation experiments in spring wheat,we analyzed the growth status and yield of spring wheat under the different bed planting technical parameter combinations（ the depth of ditch,the width of ditch,slope of ditch and width of ridge）. The results showed that the treatment with 40 cm ridge width,15 cm ditch depth,15 cm ditch width and 1： 1 slope was the best. The yield was 10. 4 % and 10. 84% higher than that with the 30 cm and 50 cm ridge widths,was 15. 89%and 8. 78% higher than that with 0cm and 10 cm ditch widths,and was 15. 7% higher than that with 20 cm ditch depth.
