Magnetic reconnection is a fundamental physical process in various magnetized plasma systems, capable of rapidly converting magnetic energy into plasma energy. The role of wave-particle interactions causing anomalous effects in triggering or accelerating collisionless magnetic reconnection remains highly controversial. Here, we investigated energy conversion and anomalous effects within a turbulent magnetic reconnection diffusion region in the solar wind using Magnetospheric Multiscale mission data. Our analysis reveals that the electromagnetic turbulence continuously gains energy from the plasma within the diffusion region. Furthermore, we find that the anomalous electric field induced by the field-particle interaction in the diffusion region is primarily provided by the electromagnetic anomalous viscosity, but its contribution to the reconnection rate is minimal. Therefore, the locally developed turbulence in the diffusion region could not modify the reconnection rate significantly in the solar wind.
