This study used two high speed digital cameras to test and analyze the process and result of spray droplet impact on the soybean leaf surface. The result showed that when spray droplets were deposited and rebound broken, K values were less than 57.7. When splashing, K values of the most droplets were more than 57.7 because of the dense pilose of the leaf surface. The droplets were splashed easily at a low impact angle. K values were less than 57.7 when impact angles were 28° and 44°. Considering the same particle size and impact angle in the deposited droplets, the maximum spreading increased and the spreading time prolonged with increasing impact velocity. The final maximum spreading ratio of the high impact velocity was close to the low impact velocity. Deposit locations significantly influenced the process and result of the droplet spreading. In the process of receding break up, the droplets separated and were broken under the rebound action of the surface tension and viscosity of the leaf surface. Compared with the droplets deposited on the leaf surface, the total final maximum spreading ratio of the droplets enlarged greatly after receding break up. The total final maximum spreading ratio of uniform droplets was larger than that of nonuniform droplets. When Weber number (We) of the impact was high, the spray droplets appeared as a series of small droplets. When We was low, the spray droplets appeared as two to three large droplets. The final maximum spreading ratio of the main body of the droplets after spraying a series of small droplets was larger than that when individual large droplets are sprayed.
