Abstract
Since the 20th century, national investment in agricultural irrigation has been increasing, indicating that the state is paying more and more attention to the “Three Rural Issues”. Along with the national emphasis on the "Three Rural Issues" and the background of increasing economic investment in agricultural irrigation, irrigation technology has been developing rapidly in Gansu Province, which is reflected in the year-on-year expansion of efficient water-saving irrigation area. The goal of water-efficient irrigation technology is to improve the water utilisation coefficient, thus optimising the planting structure of crops and increasing crop yields. Therefore, a variety of high-efficiency water-saving irrigation technologies such as pipe irrigation, sprinkler irrigation and micro-irrigation have been vigorously promoted and applied. The article analyses the current status and benefits of high-efficiency water-saving irrigation infrastructure in Gansu Province, and aims to provide data support and theoretical guidance for the development and improvement of high-efficiency water-saving irrigation in the province.
