The invention relates to a static energy storage type atomized disc, which comprises a bottom in a circular plane shape and a sidewall part extending outwards from the bottom to form a bell mouth shape; a ring of waterproof wall is fixedly arranged on the surface of the inner side of the bottom; and a metal film layer is arranged on the inner annular surface of the bottom between the waterproof wall and the sidewall part. At that time, the atomized disc is like a capacitor which can store the energy of static charges; compared with the atomized disc fully made from plastic in the prior art, when liquid with the static charges conveyed by a liquid conveying pipe is contacted with the metal film layer on the inner annular surface of the atomized disc, the atomized disc can charge instantaneously and store energy and reversely carries out the energy replenishing and conveying of the static charges on atomized liquid, thereby strengthening the energy of the static charges contained in the sprayed atomized drops and further increasing the adsorption density and the strength of adhesive force between the atomized drops and the surface of stem leaves of crop in order to promote the killing effect of electrostatic spraying.
