As an important part of social production and life, agriculture's dependence on water resources has become increasingly prominent. But in fact, China's total water resources reserve and its distribution are not optimistic. The lack or unreasonable use of water resources in some areas hinders the development of agriculture. In order to solve this problem and realize the balanced regulation of water resources, it is necessary to construct scientific irrigation and water conservancy projects. Through irrigation and water conservancy projects, the allocation and use of water resources can be further optimized to provide stable water resources guarantee for agricultural development. This article will be based on this issue. The development and application of irrigation and water conservancy projects in agriculture are analyzed in depth to provide reference for the development of agriculture in China.展开更多
