Several Factors Affecting The Spraying Effect Of Agricultural Spraying Uav

Summary: Although agricultural spraying uav are highly adaptable to terrain operations, as a "new" spraying method for crop pests and diseases, spraying effect is a frequently mentioned problem, which is also the key to whether agricultural spraying uav can be fully promoted. So what factors will affect the spraying effect of agricultural spraying drones?
Although agricultural spraying uav are highly adaptable to terrain operations, as a "new" spraying method for crop pests and diseases, spraying effect is a frequently mentioned problem, which is also the key to whether agricultural spraying uav can be fully promoted. So what factors will affect the spraying effect of agricultural spraying drones?
1. The effectiveness of agricultural spraying uav pesticides
Because the agricultural spraying uav use ultra-micro high-concentration spraying, the general dosage is about 500-700 ml per acre. At present, the pesticides used in domestic pesticide spraying plant protection drones are basically concentrated on ordinary pesticides sold on the market. Of course, agricultural spraying uav is also possible to use aviation ultra-trace pesticides specially produced by some pesticide manufacturers and corresponding auxiliary additives to ensure the pesticide’s Effect.
2. Agricultural spraying uav spraying method
Agricultural spraying uav use less medicine per unit area, and the uniformity of spraying is crucial. If there is no flight control, the height, speed and spray volume of agricultural spraying drones cannot be linked, especially when the aircraft is hovering, the amount of medicine used under the aircraft increases sharply, causing drug damage. Uneven flying distances cause repeated spray leakage and affect the spraying effect. Therefore, Agricultural spraying uav is necessary for the agricultural spraying drone to maintain a uniform speed and a certain height during the entire operation process, so as to ensure the effect.
3. The technical level of agricultural spraying uav operators
Although most of the agricultural spraying uav have been installed with industrial-grade flight control systems to ensure the altitude of the aircraft is stable, the actual flight speed still needs to be controlled manually, so the proficiency of the pilot's operation will directly affect the spraying effect. . Moreover, the pilot must have the corresponding observation and judgment ability in the actual operation process to reduce the leakage rate, re-injection rate and mis-injection rate in the operation.
4. Agricultural spraying uav spraying system
Agricultural spraying uav currently mainly use pressure nozzles and centrifugal nozzles. Because the range of the pressure nozzle's flow rate with pressure changes is relatively small, the effect of controlling the flow rate according to the speed of the aircraft is not obvious. The centrifugal sprinkler can adjust the flow rate according to the speed of the aircraft. However, due to the high-speed rotation of the centrifugal sprinkler, the pesticide mist is relatively fine, and it is prone to drift and steaming. characteristic.

In the hilly area, agricultural spraying uav can separate man-machine and pesticides, have high operating efficiency and strong adaptability. With the continuous improvement of the ecosystem, agricultural spraying uav will definitely become a trend.
