Water Conservation Irrigation and Water Conservancy Engineering of Farmland under the Background of Rural Revitalization

: The sustainable development of resources is one of the challenges facing the world. However, China's water resources are very scarce, and high-efficiency water-saving irrigation projects are an important means to achieve the sustainable development of water resources, which deserves our in-depth study. The purpose of this paper is to discuss the development of farmland water-saving irrigation through the study of the quantity and distribution of water resources, the characteristics and laws of drought, the current status of farmland irrigation and water-saving, and a comprehensive understanding of the water conservancy construction and water-saving irrigation farmland in the research field. Support development, and analyzed the problems and deficiencies in water-saving irrigation technology and water-saving irrigation construction. Comprehensive evaluation of the benefits of water-saving irrigation in farmland using the method of donating materials and expert consultation, the economic, social and ecological environmental benefits of the project were evaluated and analyzed, and the evaluation results were analyzed and summarized. Up to 4%, with a satisfaction rate of 29%, through the combination of theory and experimental data, we have come up with a strategy to improve the efficiency of water-saving irrigation in farmland. The research results show that efficient water-saving irrigation enhances the irrigation capacity and improves the basic environment for crop growth. Increased agricultural productivity, maximized and rationalized benefits.
