摘要:

【目的】了解间隔交替波涌灌溉对水流推进速度和灌水质量的影响，探究其替代波涌灌溉的可行性。【方法】以冬小麦为研究对象，设置波涌灌溉组（S）、间隔交替波涌灌溉组（AS）、间隔固定波涌灌溉组（FS）以及连续灌溉组（C）4个处理，分析比较了不同灌溉处理对水流推进速度、灌水均匀度、水分利用效率及小麦产量的影响。【结果】波涌灌溉处理下的水流推进速度明显快于连续灌溉的。4种处理下的灌水均匀度S处理为最佳，均值具体表现为：S处理>AS处理>FS处理>C处理；冬小麦产量均值表现为：AS处理>S处理>FS处理>C处理，其中与S处理、FS处理相比，AS处理有更好的增产效果；3种波涌灌溉方式的水分利用效率均值表现为：AS处理>FS处理>S处理，较C处理依次提高了43.84%、28.76%、26.03%。【结论】间隔交替波涌灌溉可显著提高水分利用效率，在山东泰安对冬小麦采用间隔交替波涌灌溉可以取得明显的节水增产效果。

Abstract:

【Objective】 Surge flow irrigation is believed capable of improving irrigation uniform and hence irrigation water use efficiency. In this paper, we investigate the impact of alternate surge flow irrigation on soil moisture dynamics and water use efficiency of a winter wheat field.【Method】We studied four irrigation treatments: standard surge flow irrigation (S), alternate surge flow irrigation (AS), fixed surge flow irrigation (FS) and continuous irrigation (C). In each treatment, we measured the advancing speed of surface water front, irrigation uniformity, water use efficiency (WUE) and yield of the wheat.【Result】The advancing speed of the surface water front under surge flow irrigation was faster than that under continuous irrigation; S gave the best irrigation uniformity, followed by AS, FS and C sequentially. The AS gave the highest yield, followed by S, FS and C sequentially. Compared with C, AS, FS and S increased water use efficiency by 43.84%, 28.76% and 26.03% respectively.【Conclusion】Our results alluded that alternate surge flow irrigation is most effective in improving water use efficiency and yield and can be used to irrigate winter wheat in Tai’an region of Shandon province.
