| 摘要: |
| 【目的】探索沟垄集雨模式下不同垄宽对玉米产量及水肥利用效率的影响。【方法】2018―2019年采用垄沟集雨种植方式,以传统平作(垄宽60cm)为对照,研究3种沟垄比［60:50,60:60；60:70(cm:cm)］对玉米叶面积指数、地上生物量、水分利用效率、肥料利用效率和产量的影响。【结果】结果表明,与传统平作相比,沟垄集雨种植技术能够增加玉米地上生物量、产量、叶面积指数、水分利用效率和肥料利用效率。垄沟集雨种植方式下,采用60cm:60cm沟垄比,两年平均叶面积指数最大,为2.9,较对照增加42.16%；产量最高,为13.13 t?hm-2,较对照增加26.37%；水分利用效率最高,为27.15 k?hm-2?mm-1,,较对照增加42.37%；肥料利用效率最高,为N:7.55 kg?kg-1；P:48.49 kg?kg-1；K:4.66 kg?kg-1,分别较对照增加177.57%,142.69%,59.58%。【结论】在华北地区,采用垄沟集雨种植方式,垄沟比60cm:60cm,能够促进玉米增产和水肥高效利用。 |

| Abstract: |
| 【Objective】In order to explore the effect of different ridge width on maize water and fertilizer use efficiency under ridge-furrow rainfall harvesting planting mode. 【Method】we used ridge-furrow rainfall harvesting planting mode during 2018-2019 years, using traditional plain cropping (ridge width 60cm) as control, researched the effect of three furrow-ridge ratios [60:50,60:60;60:70(cm: cm)] on maize leaf area index, aboveground biomass, water use efficiency, fertilizer use efficiency and yield. 【Result】The results show that, compare with traditional plain cropping, ridge-furrow rainfall harvesting planting technique can increase maize aboveground biomass, yield, leaf area index, water use efficiency and fertilizer use efficiency. Under ridge-furrow rainfall harvesting planting mode, adopt furrow-ridge ratio 60cm:60cm, the two-years average leaf area index was the largest at 2.9, which increase of 42.16% over the control; yield was the highest at 13.13 t?hm-2, which increase of 26.37% over the control ; water use efficiency was the highest at 27.15 k?hm-2?mm-1, with increase of 42.37% over the control; fertilizer utilization efficiency was the highest N:7.55 kg?kg-1；P:48.49 kg?kg-1；K:4.66 kg?kg-1, with increase of 177.57%, 142.69%, 59.58% over the control respectively. 【Conclusion】Therefore, in north China, use ridge-furrow rainfall harvesting planting mode, furrow-ridge ratio is 60 cm:60 cm which can promote maize production , water and fertilizer use efficiency. |
