The invention relates to an electric pole. A protecting frame (02) comprises a basket and a connecting plate, one side of the connecting plate is welded together with the basket along the radial direction of the basket, a supporting frame (03) is a semicircular support, lug plates are arranged on the left side and the right side of the semicircular support, an inner ring of the supporting frame (03) is fastened on an electric pole column (01), the connecting plate of the protecting frame (02) is clamped between the lug plates of the supporting frame (03), and a fastening bolt (04) penetrates the lug plates of the supporting frame (03) and the connecting plate of the protecting frame (02) and is fixedly tightened. A sensor (25) is used for sensing the humidity of soil and transmitting sensed soil humidity values to a controller (41) in real time, and the controller (41) controls a signal electromagnetic switch (20) to open or close an irrigation portion according to the soil humidity values. By additionally arranging the supporting frame on the basis of an original electric pole column and fixing the basket onto the electric pole column by the fastening bolt, flowers and plants can be cultivated on the original electric pole.
