| Abstract: |
| 【Background】Water scarcity is an important factor affecting the sustainable development of agriculture in northwest China. In Xinjiang, the problems of limited water resources, low rainfall, intense evaporation, and fragile ecology have been highlighted. Therefore, agricultural development and economic construction must be carried out under limited water resources. It is extremely urgent to improve the utilization rate of water resources and increase the yield per unit area of crops on the premise of ensuring the quality, and develop facility agriculture. It may be seen that the development of facility grape and the improvement of water resource utilization rate and water productivity through optimizing crop irrigation system is the inevitable way for regional sustainable development. 【Objective】The objective is to explore the optimal irrigation quota and irrigation methods for grapes to improve yield and quality. 【Method】The test used a common irrigation cultivation method of the small-pipe outflow with the Red Globe in the facility greenhouse in Xinjiang. The four water treatments T1, T2, T3, and T4 (the irrigation quota is 580mm, 620 mm, 660 mm, 700 mm respectively) were studied on grape transverse and longitudinal diameter, yield, the weight of single grain, grape soluble solids, titratable acid, glucose content, and irrigation water use efficiency. 【Result】Different water treatments have an impact on the fruit transverse and longitudinal diameter, quality and yield of grapes, . The transverse diameter of T4 treatment was significantly higher than that of other treatments (P<0.05), but there was no significant difference in longitudinal diameter between T3 and T4 treatment. In terms of production,and the yields of T3 and T4 treatments are significantly (P<0.05) higher than those of T1 and T2 treatments, and there is no significant difference in weight of single grain in T3 and T4 treatments; The grape soluble solids and titratable acid of T2 treatment decreased significantly compared with T3 and T4. But the glucose content of T2 treatments was the largest, and there was no significant difference from T3 treatment. The irrigation water use efficiency of different treatments showed a trend of decreasing first and then increasing with the increase in irrigation water volume. T1 treatment was the largest, followed by T4, T3 treatment, and T2 treatment was the smallest, and T1 treatment was significantly different from the other three treatments on irrigation water use efficiency. 【Conclusion】Comprehensive analysis of grape yield, quality indicators, and irrigation water use efficiency, the irrigation quota of about 660mm is determined as the optimal irrigation index under these experimental conditions. |
