The invention discloses a terpolymer, a preparation method and application of the terpolymer in wheat leaf antibacterial water retention, the structural formula of the terpolymer is shown in the specification, and x/x + y + z = 0.05-0.25; and y/x + y + z is equal to 0.05-0.25. The terpolymer is strongly combined with the surface of a plant after being atomized into a film on a leaf, so that the water retention capacity of the leaf is enhanced, stomatal transpiration is reduced, the leaf is in a relatively good moisture state, and an important moisture support is provided for photosynthesis of crops. A hydrophilic-hydrophobic microcosmic phase separation channel is formed in the terpolymer coating, and the formed channel is beneficial to diffusion of gas molecules, so that a breathable effect is achieved. And after the coating is used, the antibacterial effect of plant leaves can be improved, and the morbidity of stem and leaf diseases such as wheat powdery mildew, anthracnose and rust disease can be reduced.
