| Abstract: |
| Drip irrigation is one of the most advanced precision irrigation technologies in the world. Based on the consulting research project of academician of China Engineering Academy “Research on the Development Strategy of Field Drip Irrigation in China”, after a two and a half years of research, the development history of domestic and international drip irrigation technology was systematically reviewed, and the general cognition of field drip irrigation in China was clarified. Combined with the development process of drip irrigation water\|saving technology in Xinjiang, the problems existing in the development of drip irrigation in China were analyzed in the following aspects: unbalanced regional development, low automation degree, high energy consumption, lack of effective management standards and norms, low utilization efficiency of water and fertilizer, and serious residue\|film pollution. Five suggestions for the development of field drip irrigation in China were put forward: (1) Formulate the development plan by areas, levels, and steps; (2) Innovate and develop the key technologies and equipment of drip irrigation informatization and automation; (3) Develop self\|pressure drip irrigation according to local conditions; (4) Develop drip irrigation technology towards standardization and normalization; (5) Improve the water and fertilizer utilization efficiency with drip irrigation system and promote the ecological sustainability of drip irrigation under mulch. Four development strategies of field drip irrigation in China were formed, including regional development and engineering construction of drip irrigation technology, integration and automation collaborative construction of irrigation and drainage pipe network, scientific problem tackling and engineering construction of large\|scale self\|pressure automatic drip irrigation system, and long\|term research on water\|saving efficiency and ecological sustainability of drip irrigation. The results provided some ideas and support for promoting the sustainable development of drip irrigation technology, supporting the idea of “water saving priority” and implementing national water\|saving action. |
