The entropic squeezing properties of the field in the system of the cascade three-level atom interacting with superposition states field are studied.When the field is superposition state of |0〉 and |1〉,the results obtained using the numerical method indicate that the entropic squeezing properties of the field is closely related to the superposition coefficient φ and is influenced by the superposition coefficient.When φ is larger than 0 and smaller than π/2,with the increasing of the value of φ,the entropic squeezing properties of the field is getting stronger.
