Agricultural stores promote drones to spray chemicals on fruit trees.

1. Introduce the advantages of unmanned aerial vehicles: It is necessary to introduce its advantages when promoting unmanned aerial vehicles to fight drugs. UAV can reach farmland efficiently and conveniently, with wide coverage, less dosage of chemicals and even atomization, which can reduce the damage caused by human operation to fruit trees.

2. Emphasize the safety of UAV: Because pesticides are potentially harmful to human body, and traditional pesticide spraying requires a lot of manpower, there are great hidden dangers in safety and sustainability. UAV pesticide spraying has the characteristics of remote control and automatic control, which can reduce the harm to human body caused by manual operation and improve the safety of pesticide use.

3. Introduce the technical characteristics of UAV: It can help farmers to better understand this technical advantage. Using GPS system for positioning, UAV can realize autonomous operation and intelligent control, and improve working efficiency. At the same time, the drone's body is small and can easily pass through narrow fruit tree branches.

4. Introduce the case of UAV: Introduce the actual situation of spraying pesticides by UAV in an orchard, which covers a larger area per unit time and reduces pesticide waste.
