A sprinkling head comprises a base member and a variational water-discharging cover having several radial ribs defining several fully discha rging openings and a mesh plate placed within and connected to the radial ribs. Six different variational sprinkling holes and two closed holes are integrally annul arly arranged on a central portion of the mesh plate. The base member is connected with the mesh plate by ultrasonic fusion and spaced from the radial ribs so that water can pass through the fully discharging openings. The base member further has a fine mesh water inlet and a T-shaped depression formed on a back face thereof. When the T-shaped depression is aligned with a water outlet of a sprinkling gun connected with the sprinkling head, water flows through a space defined by the sprinkling gun, the water-discharging cover and the base member and out of the fully discharging openings and all the sprinkling holes.
