The invention discloses a method for testing the dynamic bonding property of a basalt fiber rebar and concrete under reciprocating loading. The method comprises steps as follows: a basalt fiber rebar and a concrete sample are placed on an inner frame, and a basalt fiber rebar on the lower side of the concrete sample extends out of the inner frame; a backing plate is placed on the upper side of the concrete sample, the basalt fiber rebar at the upper part of the concrete sample penetrates through a hole in the center of the backing plate; strip-shaped plates are placed on the upper side of the backing plate and placed on the lower surface of a bottom plate to clamp the concrete sample; the basalt fiber rebar at the lower part of the concrete sample is connected with a clamp, and a displacement sensor and the basalt fiber rebar are connected through a magnetic gauge stand; a pull and press actuator is controlled by a computer to realize reciprocating loading and produce pull force for the basalt fiber rebar, an
