Application Research and Prospect of Intelligent Irrigation Control System in Greenhouse

At present, intelligent irrigation control system mostly adopts timing control, that is, equipment works when it reaches start time, and stops when it reaches irrigation duration．Automatic irrigation has been realized to a certain extent．However, due to different water requirements of crops in different growth periods, it is difficult for irrigation control system to generate irrigation schemes consistent with needs of crops．Intelligent irrigation technology of greenhouse has started relatively late in our country, and has not been widely used, and its control mode and control strategy are different in those areas where intelligent irrigation has been used．Taking intelligent irrigation control system as starting point, composition and problems of greenhouse intelligent irrigation control system were expounded, and its future development was prospected．
