| 摘要: |
| 本文围绕咸水淡化技术在农业灌溉中的应用，归纳与评述了各类咸水淡化技术在在农业方面的应用场景与处理效果。目前淡化水灌溉技术已经在以色列、西班牙、澳大利亚等国家广泛应用。其中反渗透技术是应用于农业最广的咸水淡化技术，电吸附技术被认为是实现低耗淡化水的关键技术，太阳能蒸馏与海冰水淡化可以因地制宜地淡化咸水。咸水淡化技术具有提高作物产量、保护土壤等优势，但存在环境污染、成本较高等局限，本文展望了淡化灌溉水的应用前景与发展方向，为咸水淡化技术在我国农业灌溉方面的研究提供参考。 |

| 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. |
