What are the advantages and disadvantages of unmanned plant protection machines?

Advantages:

1. High efficiency. It is 15-20 times that of manual work.

2. Save water and medicine. Using plant protection drones with special pesticides for aerial control saves water, uses less pesticides, and is safer and more environmentally friendly.

3. Widely adaptable. Drones can be used for plant protection operations on flat lands, hills, hills and depressions. Compared with large-scale ground-walking plant protection equipment, there is no need for passage.

4. Little harm to human body. The drone operator is kept away from the drug during operation, and there is almost no harm.

Disadvantages

1. The battery life of electric plant protection drones is short and the load needs to be improved. Oil plant protection drone technology still needs to be improved.

2. Industry standards need to be formulated.
