Abstract The achievements in irrigation and drainage in China in the past 70 years are reviewed in terms of irrigation and drainage facilities, irrigation and drainage management systems and investment policies, respectively. With the increase in irrigation area, irrigation and drainage facilities have greatly improved grain yield and agricultural production capacity of China. The irrigation and drainage management system has experienced huge changes, i.e. from the collective management of farmers to the management of state-owned back-bone institutions, which promoted the rapid development and healthy operation of irrigation and drainage projects. Investment policies served water conservancy infrastructure effectively. However, presently in China, there are still problems such as poor utilization efficiency of irrigation water, small proportion of water and fertilizer integrated irrigation farmland and low extent of informatization of irrigation system, which are far behind the development of high-quality agricultural production. Combined with the strategic needs of national food and ecological security, the future opportunities and challenges in water-saving irrigation equipment and technology to China are proposed in a few aspects, namely, water-saving transformation of large and medium-sized irrigation districts, water and fertilizer integrated water-saving irrigation equipment and technology, spray and drip irrigation, pipeline water delivery irrigation and pump station upgradation. In order to promote the development of water-saving irrigation industry in China, taking the measures, such as strengthening the theoretical research and independent innovation of irrigation and drainage equipment, developing efficient, energy-saving and environmental protection technologies and products, and improving industrial informatization, intelligence and networking, is the inevitable trend to achieve agricultural mo-dernization.
