Through the intelligent distribution equipment assisted by the Internet of Things, remote sensing, and artificial intelligence, the law of crop water and fertilizer demand, the dynamic release of fertilizer, and the interaction mechanism of rhizosphere water and fertilizer are analyzed to implement precision agriculture. Intelligent dispensing equipment: automation equipment, control system, and feedback mechanism. Internet of Things: sensor, networked device, real-time monitoring, and data storage. Remote sensing technology: satellite remote sensing, UAV remote sensing, and ground remote sensing. Artificial Intelligence (AI): data processing and analysis, machine learning algorithm, prediction model, and decision support system. Water and fertilizer requirements of crops: water demand rule and fertilizer requirement rule. Fertilizer release dynamics: fertilizer type, release mechanism, and release model. Rhizosphere interaction mechanism of water and fertilizer: rhizosphere environment and interaction of water and fertilizer.
