The performance research on a two-phase gas-liquid electrostatic induction nozzle was carried out in the lab. The results showed that the droplets deposition and coverage ratio on the upper leaf surfaces achieved by electrostatic spraying were increased by 43.03% and 22.07%, respectively. The coverage ratio on the down leaf surfaces was up to 30.95%; when gas flow rate was 1.4m3/h, liquid flow rate was 60mL/min, voltage was 1000 V, chargetomass ratio could reach to 3.2mC/kg, which was high enough for electrostatic spraying. The optimum work parameters were: gasliquid ratio of 0.18, spraying angle of 0°, and voltage of 1000 V. 
