Wind power blade root connecting structure and wind power blade

The invention relates to the technical field of wind power generation, and particularly discloses a wind power blade root connecting structure and a wind power blade. The wind power blade root connecting structure comprises a wedge-shaped block and a UD block. The wedge-shaped block comprises a first body, the first body is of a cylindrical structure, a first inclined face and a second inclined face are arranged on the side face of the first body, and the first inclined face and the second inclined face intersect with the center line of the first body. The wedge-shaped block is located between every two adjacent UD blocks, each UD block comprises a second body, and each second body is provided with a third inclined face corresponding to the corresponding first inclined face and a fourth inclined face corresponding to the corresponding second inclined face. According to the wind power blade root connecting structure, stress concentration can be reduced, the failure risk is reduced, and the load bearing capacit
