| 摘 要： | 大田条件下研究了陇中半干旱区小麦/玉米复合群体集雨补灌的产量及水分效应。结果表明,复合系统的产量水平和水分利用效率(WUE)因补灌而显著提高,小麦组分也取得明显的边行优势。根据对产量、WUE和灌水利用效率(IWUE)的综合分析,认为在小麦播前补3 mm水,小麦拔节期、孕穗期各补21 mm水,玉米抽雄期补45 mm水是该区最理想的补灌模式。

| Abstract: | The results of the experiment conducted in the semi-arid area of central Gansu showed that the yield and water use efficiency(WUE) of wheat/corn compound colony could be improved by supplementary irrigation with catchment rainfall.The marginal predominance of wheat was obvious,and there were insignificant differences among the treatments.According to the results of yield,WUE and IWUE,the best cropping and supplementary irrigation pattern was determined for semi-arid areas. |
