The irrigation and drainage machinery play an important role in the irrigation, combat flood and drought, ensure agricultural steady high production and ecological environment construction, and it has broad market and the developing prospects. After more than 50 years development, China has made great progress in fundamental research, technical performance and scale in irrigation and drainage machinery, but mentioning about product security reliability, variety specification, performance quality, matching degree and post-sale service, China still has long way to go to improve them. The new technology, new materials, new craft research and application efforts in the field of drainage and irrigation machinery should be enhanced, and basic theoretical research should be strengthened, product performance should be improved and the reliability, systematization and advantage of equipment and technology should be perfect and enhanced so as to promote drainage and irrigation machinery development in the orientation of efficiency, multifunction, low energy consumption, environmental protection and intelligence. 
