The kinetic energy of sprinkler irrigation water droplets is the source of the energy required to break up soil aggregates, detach particles, and splash in fields, which is detrimental to advancing sprinkler irrigation awareness and widespread application. However, it remains uncertain whether the influence of the crop canopy on the splash erosion rate in soils with varying textures under sprinkler irrigation conditions has any bearing. The response mechanism of the splash erosion rate of different textured soils to sprinkler water specific power was elucidated in this study. The influences of growing maize plants and irrigation features on the splash erosion rate were clarified. A relationship between the sprinkler water partitioning process and energy conversion was developed. The results showed that the specific power of the sprinkler water positively influenced the soil splash erosion rate. The splash erosion risk of the different textured soils was ranked as follows: sandy soil > loamy soil > clay soil. The threshold kinetic energy of the water droplet population was 0.0214, 0.0262, and 0.0361 J
