In order to improve the wind sprayer on the fruit tree canopy area droplet deposition, reduce the fruit tree rows of droplet drift, solve the environmental wind speed airflow caused by the nonuniform canopy droplet deposition, a kind of umbrella wind field anti-drift spraying device was designed, anti-drift spraying device regulating mechanism on the anti-drift spraying device umbrella wind field by using a combination of simulation tests and physical tests was used to explore the impact of wind field. With the anti-drift spray device outlet diameter, side wind speed, spray pressure as factors, respectively, single-factor and three-factor three levels of apple canopy droplet drift deposition test was done to analyze the influence of umbrella wind field on the effect of droplet canopy deposition law. The results showed that the droplet drift rate, center-of-mass distance, and coefficient of variation of droplet deposition distribution were reduced by 27.5%, 16.2%, and 7%, respectively, compared with that of the normal airflow. The three factors have more significant effects on the droplet deposition characteristics, and their influences in descending order were side wind speed, spray pressure, and outlet diameter. The multi-island genetic algorithm was used to optimize the application parameters with the highest deposition, and the results showed that the optimal value of droplet deposition was 6.34μL/cm2 when the side wind speed was 2m/s, the spray pressure was 0.4MPa, and the outlet diameter was 70mm, and the actual validation value with the optimal combination of the factors was 5.96μL/cm2, with a discrepancy rate of 5.9%, and the experimental validation results were basically in agreement with the model prediction. The experimental validation results were basically consistent with the model prediction.
