Abstract
A testing device for integrated irrigation and disinfection includes a centrifugal pump, pressure sensors, flow sensors, an ion concentration sensor, and a control system. The testing device has comprehensive functions of fertilization, spray and drip irrigation load simulation, water and fertilizer parameter detection, fertilizer absorbing channel parameter detection and backflow channel parameter detection. The detection of nutrient ion concentration in a nutrient solution is combined with the aspects of irrigation, dynamic preparation of a nutrient solution and disinfection of a nutrient solution, to realize a high-precision dynamic preparation of a nutrient solution and irrigation area load simulation, and satisfy the requirements on a test system during a research and development process of an irrigation and fertilization system. The testing device is applicable to the research on the techniques and the development of a system for precise irrigation and accurate preparation of a nutrient solution in the field of facility agriculture.
