In order to improve the deposition in the target area of orchard wind-fed spray and reduce the drift of fog drops between rows, a V-shaped anti-drift spray device with multi-airflow cooperation was designed on the basis of conventional airflow assisted spray. CFD simulation was used to verify the anti-flapping effect. The simulation results showed that the droplet deposition area of multi-airflow was more concentrated than that of single air flow, and the droplet escape rate was reduced by 40.3%. The feasibility of anti-drift and droplet uniformity test under multi-airflow and single airflow were carried out. The results showed that the droplet drift rate, quality center distance and droplet deposition distribution coefficient of variation were reduced by 29.2%, 25.2% and 30.2% compared with single airflow, respectively. The wind speed in the V-shape wind field, the wind speed in the crosswind and the spray pressure were taken as factors. Single-factor and three-factor and three-level fog droplet drift deposition experiments were carried out in apple tree canopy. The influence law of multi-ariflow V-shaped wind field on fog drop canopy deposition was analyzed. The results showed that when the crosswind speed was 3m/s, the deposition density and deposition amount of fog droplets under the synergistic action of multiple flows were increased by 28.7% and 17.4%, and the drift amount was decreased by 21.8%, respectively, compared with single ariflow. The three factors had significant influence on the droplet deposition characteristics. The influence degree from large to small was the wind speed in V-shaped wind field, the wind speed in crosswind, and spray pressure. The optimal model for predicting droplet deposition was established by response surface. When the crosswind speed was 2m/s, the spray pressure was 0.52MPa, the wind speed was 21.8m/s in the V-shaped wind field, the optimal value of fog droplet deposition was 4.81μL/cm2. The result of field experiment was 4.72μL/cm2, which was consistent with the prediction of fog droplet deposition model.
