| Abstract: |
| 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. |
