| Abstract: |
| Changes in the characteristics of water and salt migration and their impact on saline-alkali soils are the main issues that need to be considered during the implementation of large-scale saline-alkali soil improvement projects. As the Hetao irrigation area is an important commercial grain production area in my country, soil salinization is a key factor affecting the high-quality development of the irrigation area. The calculation and analysis of water and salt balance has gradually become an important content of the study of water and salt transport in the process of saline-alkali land management in the irrigation area.In this paper, the 50,000 mu "salt, increase grass (forage) and grazing" experimental demonstration project area in Wuyuan County is used as the research area, and the regional soil-groundwater-surface water information fixed-point monitoring method is adopted, and the digital agricultural cloud platform is used to obtain monitoring data.The annual irrigation and drainage period is a cycle, discussing the impact of irrigation water and rainfall; deep soil leakage; soil groundwater replenishment; soil evaporation; open ditch drainage on regional water and salt transport. Calculation of water and salt balance under the condition of improving saline-alkali land in Hetao Irrigation District.Quantitative analysis showed that during the improvement period of the study area, the salt control effect and salt discharge efficiency increased year by year, the root layer soil changed from salt accumulation to desalination, and the water and soil environment improved year by year. |
