To address the time-consuming and wasteful manual pesticide application faced by farmers in rural Fujian, drones equipped with multispectral sensors deploy low-altitude spraying along pre-set routes, ensuring uniform atomization. They also collect real-time data on soil nutrients and crop health, generating digital maps to guide field management.

Effects:
Pesticide utilization has been improved, environmental pollution has been reduced, pesticide application time for 300 mu (approximately 1,000 acres) of seed rice has been reduced from 10 days to 3 days, reducing costs by 30%.
