| 摘 要： | 采用电子蒸散计(Lysimeter)逐日测定春小麦和玉米生育期的蒸散(地面蒸发和植物蒸腾)量, 结果表明, 作物的蒸散量随生育期的进程而变化, 并受供水条件所制约。春小麦全生育期的最大蒸发蒸腾虽约312mm, 最小蒸发蒸腾量245mm; 玉米全生育期的蒸发蒸腾量约468mm。春小麦套种玉米的增产节水效果显著, 其产量比单种春小麦和玉米的产量高约50%, 而蒸散耗水量比单种的低18%。本文就河西干旱区农业节约用水合理灌溉问题作了讨论。

| Abstract: | The evapotranspiration of spring wheat and maize during the developmental stages were measured daily with electronic Lysimeter. The results showed that the evapo transpirations of them varied with their developmental stages and were controlled by the watering conditions.The Yield-increasing and water-saving effects of inter planting spring wheat with maize were notable.The water-saving problem and rational irrigation in the Hexi Region were also discussed in the paper. |
