Realizing agricultural green and low-carbon development is a major strategic requirement for China's agricultural development.The innovation and promotion of water-saving and drought-resistant rice provides a new solution for breaking through the bottleneck of resource constraints in China's agricultural development,alleviating the pressure of ecological environment,promoting food security and increasing farmers'income.Compared with the traditional rice planting mode,the planting method of water-saving and drought-resistant rice with direct dry seeding and drought management can save more than 50％of freshwater resources,reduce about 30％of chemical fertilizer application,and reduce more than 90％of methane emissions,which greatly expands the space of rice planting,realizes cost saving and efficiency increasing,and increases farmers'income.It has significant ecological,economic and social benefits.The countermeasures and recommendations were put forward from the aspects of strengthening the innovation and development of varieties and technologies guided by agricultural green development,establishing and improving the technology promotion system for agricultural green development,and constructing and improving policy and institutional systems suitable for agricultural green development.
