摘要
储水灌溉在北方灌区被普遍应用,目的是将秋冬季多余的水分储存于土壤,供作物来年生育期利用。但储水灌溉灌水定额普遍偏高,水分利用率低,因此在北方缺水地区,研究提高储水灌溉的水分利用率,是节水灌溉制度研究的重要内容。对储水灌溉的水分利用效率进行了研究,探讨了在河西内陆区实行节水型冬季储水灌溉的可行性,分析了节水潜力。
In the northern China, water-reserving irrigation technology is widely used to store excess water during autumn and winter periods in soil for crop use next year. Traditionally, the volume applied in water-reserving irrigation is large, and the water use efficiency is very low. In dry region with limited water resources of northern China, it is necessary to study on improving water use efficiency and water-saving irrigation scheme. The paper deals with the water use efficiency of water-reserving irrigation, and discusses the feasibility and the potentials of applying water-saving technology in water-reserving irrigation in the Hexi Corridor.
