Abstract:

Salt water desalination technology is the most reasonable way to develop and utilize marine resources. This article describes the harm of soil salinization caused by direct irrigation with saline water. It outlines the significance of salt water treatment and precision irrigation, and introduces the brackish water desalination process and precision irrigation process. Meanwhile, this paper proposes a combination of brackish water treatment and precision irrigation and discusses the development trend of salt water desalination and precision irrigation. The study analyzes the two major factors of energy and technology that restrict the development of salt water desalination technology, and concludes that water-saving irrigation technology will integrate remote irrigation management and comprehensive control analysis in the future, which can truly achieve intelligent irrigation management. The combination of solar technology and nanofiltration technology will have broad market prospects, and materials such as nanoparticle membranes and photothermal conversion carbon fibers will be the hot spots of seawater desalination research. Therefore, the combination of salt water desalination technology and precision irrigation will greatly improve the resource utilization efficiency and the soil environment, which will be more in line with the future development trend of ecological technology.

Key words: water resources, seawater agriculture, salt water desalination, precision irrigation, soil salinization
