A futuristic and professional background wall image for a smart irrigation systems lab. Scene layout (3 layers): Bottom layer: vast farmland with smart irrigation devices (weather station, soil moisture station, fertigation machine, irrigation outlets). Middle layer (Applications): four floating tech modules above the farmland, representing: Sky-ground integrated smart monitoring (satellites, drones, ground sensors working together) Smart water-fertilizer integrated control (irrigation network, fertigation mixing, smart valves) Agricultural foundation model (AI data flows, neural network diagrams, prediction dashboards) Agricultural robot control (agri robots working collaboratively, autonomous navigation) Top layer (Cloud services): cloud platform with cloud computing, edge computing, Docker, and microservices icons connecting all modules. Use a color scheme of tech blue, vitality green, and light gray, with clear structure and academic tone, emphasizing the theme “Technology Empowering Smart Agriculture”. See more
