Water-fertilizer-pesticide integrated system and working method

The invention provides a water-fertilizer-pesticide integrated system and a working method. The system comprises a monitoring device which is used for shooting and monitoring the growth state of crops; a upper computer platform is used for analyzing the information acquired by the monitoring device to obtain the irrigation water amount, the fertilizer type, the fertilization amount, the pesticide type and the usage amount required by plants; a control system receives information transmitted by the upper computer platform and controls starting and stopping of a pump valve through a control cabinet, so that irrigation, fertilization and pesticide application are carried out on the plants. Uniform irrigation, fertilization and pesticide application on the crops are facilitated, soil looseness can be guaranteed, crop growth is promoted, diseases and insect pests are reduced, and integrated management of irrigation, fertilization and pesticide application is achieved. 本发明提供了一种水肥药一体化系统及工作方法，所述系统包括监控设备，用于对农作物的生长状态进行
