摘要
试验利用山东引黄灌区内原有机井灌溉设施,在灌区生产较普遍规格（3m×95m）畦田内进行波涌流灌溉,并在水流推进、土壤含水率变化、冬小麦水分利用效率方面与连续灌溉进行了对比。试验条件下研究结果表明,周期数为2,节水率为10%的波涌流灌第二周期平均水流推进速度为连续灌溉的1.85-1.88倍,波涌流灌第二周期停水后的冲长为连续灌停水后的1.50-1.71倍,可以高质量完成灌溉任务,并且冬小麦水分利用效率提高10.41%。
This test used the original pumped well irrigation facilities to irrigate the border check of general specification （3 m ＆#215; 95 m） with surge irrigation system in Yellow River irrigation area of Shandong Province .And we compared the surge irrigation water flow propulsion ,change of soil water content and water use efficiency of winter wheat with continuous irrigation .Under the test condi‐tion ,the results showed that the second period of surge irrigation which had two periods and whose water-saving rate was 10% was 1 .85-1 .88 times the average speed of continuous irrigation .And the second period＆#39;s water propulsion length after watering was 1 .50-1 .71 times that of continuous irrigation .These proved that surge irrigation finished the irrigation task with high quality .At the same time ,the water use efficiency of winter wheat increased by 10 .41% .
