in rial operation and technical publicity activities，researcher xing suli explained the design purpose, research status and development advantages of water and fertilizer intelligent control equipment, and dr. gao pengbo introduced the system design principle, use function and operation precautions.
at present, the technology applies solar power supply and 4g wireless transmission technology. with the help of surface drip irrigation system, flow meters and automatic control valves are used to accurately control the input of water and nutrients in different periods. among them, three recommended management modes are adopted for nutrient input, namely: expert program human-computer interaction mode, computer model recommendation management and manual mode. in the process of detection and trial operation, the control system of water and fertilizer intelligent control equipment, field pipeline system, sensor system, etc. were operating normally. this activity laid a good foundation for further application and promotion.
