This article analyzes the theoretical foundations of differential micro-spraying technology used in plant protection processes in small-scale farming and household plots. It also highlights the disadvantages of traditional spraying methods, including excessive resource consumption and the resulting environmental issues, while demonstrating the advantages of differential micro-spraying technology. The relationship between droplet size, pressure, and spraying efficiency in the micro-spraying process is theoretically substantiated. The research findings indicate that differential micro-spraying technology plays a significant role in reducing pesticide consumption, increasing crop yields, and ensuring environmental sustainability.
