Abstract: As two main factors affecting growth of crops, water and fertilizer management will directly affect yield and quality of crops．In view of extensive management mode, low degree of automation and serious waste of water and fertilizer in agricultural water and fertilizer management in China, with aid of wireless communication technology, automatic control technology and sensor technology and other modern technology, a set of intelligent irrigation control system has been developed, which integrated field information collection, remote automatic control, equipment operation status monitoring and irrigation process regulation, etc．It could effectively improve utilization rate of water and fertilizer and automation and refinement level of field management．At the same time, it could also accurately measure water consumption in system and irrigation areas, provide data support for calculation of irrigation water price and comprehensive reform of agricultural water price, meet development demand of modern agriculture．
