In order to study the process of charged droplets impacting the plant target interface，a test method by using PDPA was given. Both the morphological characteristics of charged droplets after impact and its causes were analyzed. The measurement results indicated that the special space movement form of charged droplets determined their unique morphological characteristics after impact. Charged droplets after impact would adhere to the interface or rebound but never splash. The existence of more fine droplets made coalescence phenomenon remarkable so as to increase the charged droplet size but decrease their number. The critical value of K for determing a single droplet’s adhesion or rebound after impact was not suitable for the process of charged droplets impacting the plant target interface. However, 30，the critical value of normal Weber number，could be a reference for determing charged droplets’ adhesion or rebound after impact. Larger tangential velocity may encourage charged droplets to rebound from the interface after impact. A part of normal kinetic energy of charged droplets would translate into tangential kinetic energy after impact. 
