| Abstract: |
| In order to get more irrigation water and to reduce the impact of salt on plants and soil, people have used desalination technology to produce freshwater in some areas. This paper focused on the application of desalination technology in agricultural irrigation, summarized and reviewed the application scenarios and treatment effects of various types of technology in agriculture. At present, desalinated water irrigation technology has been widely used in Israel, Spain, Australia and other countries. Reverse osmosis technology was the most widely used desalination technology for agriculture. Electrosorption technology was considered to be the key technology for realizing low-consumption desalination water. Solar energy distillation and sea-ice water desalination could desalinate brackish water according to local conditions. The application of desalination technology has advantages of improving crop yield and protecting soil, but also has limitations in terms of environmental pollution and high cost. At the end, the agricultural application prospect and development direction of desalination technology were concluded. This study provides reference for the development of water desalination technology in agricultural irrigation in China. |
