Abstract: In the process of agricultural development, agricultural water-saving technology has always been one of the most crucial and key technologies, and because the distribution of water resources is very uneven. And globally, the shortage of water resources has become an issue that is urgently needed to be solved by the people of all countries in the world. Agricultural water-saving technology has a long history of development. From the simplest canal construction and other agricultural irrigation facilities, we can clearly identify the design traces of agricultural water-saving. In the process of modern agricultural development, the application of agricultural water-saving technologies is becoming more and more common, and as modern materials become more and more advanced, the water-saving effects that can be achieved are also getting better and better. This article focuses on the research process and the future development trend of modern agricultural water-saving technologies, hoping to provide reference for relevant researchers of agricultural water conservancy technology.
Key words: agriculture; water-saving technology; research process; development trend
