In order to realize the monitoring and management of the greenhouse water and fertilizer integration system, a water and fertilizer integration system based on the Internet of things is designed. The system design adopts the structure of the Internet of things, the acquisition control layer collects the greenhouse environment parameters through the STM32 single-chip microcomputer, collects the working parameters of the executive module through PLC, controls the water pump and the valve to complete the fertilization irrigation, and transmits the data to the application layer through GPRS. The web application layer is designed and developed with B/S architecture, MySQL as the database management system, and Java as the functional module of the system. The system has been tested by operation, fast response of water and fertilizer integrated execution module through PID control, and overshoot of 6.8%. The maximum absolute error of EC value of water and fertilizer mixture is 0.5 mS/cm。
