| 为探究去电子水灌溉对冬小麦生长及其水分利用的影响，选取关中平原典型灌区为研究区开展大田试验。以冬小麦“小偃22号”为供试作物，设置不同的灌水类型（普通水与去电子水）和灌溉量水平（60、120、180 mm与240 mm），分阶段对冬小麦的生长指标与光合指标进行测定，分析冬小麦的耗水特性、土壤水分变化状况及水分利用效率。结果表明，同一灌溉量水平（180 mm）下，与普通水灌溉相比，去电子水灌溉的冬小麦生长速率更快，同时耗水量较高，其籽粒产量与水分利用效率亦显著提高了17.8%与15.1%；与0 mm灌溉相比，去电子水灌溉的冬小麦增产46.9%，高于普通水灌溉处理（24.7%）。去电子水不同灌溉量处理中，灌溉量为180 mm时冬小麦的籽粒产量与水分利用效率均最高。因此，可以将去电子水灌溉180 mm作为关中平原冬小麦高效用水和高产的较优灌溉方案。 |

| To explore the effect of irrigation with de-electronic water on the growth and water use of winter wheat, a field experiment was carried out in Guanzhong Plain, a typical irrigation area. Winter wheat ‘Xiaoyan 22’ was used as the test crop. Different irrigation treatments (normal and de-electronic water)and irrigation amounts (60, 120, 180 mm, and 240 mm)were used. The growth and photosynthetic indexes of winter wheat were measured in different stages, and the water consumption of this crop, variation in soil moisture, and water use efficiency were analyzed. Compared to winter wheat irrigated with normal water, winter wheat irrigated with de-electronic water under the same irrigation amount (180 mm)had a higher growth rate and water consumption, its grain yield and water use efficiency increased significantly by 17.8% and 15.1%, respectively. Compared with zero irrigation, the yield of winter wheat increased by 46.9% under the de-electronic water irrigation treatment, which was higher than that under the normal water irrigation treatment (24.7%). Under different de-electronic water irrigation treatments, winter wheat had the highest grain yield and water use efficiency with an irrigation amount of 180 mm. Therefore, irrigation with 180 mm de-electronic water can be implemented as an improved irrigation scheme for efficient water use and high yield of winter wheat in the Guanzhong Plain. |
