The invention discloses a method for identifying aquilaria sinensis, a primer, a probe and application of the method. The primer and the probe have exclusive specificity of the aquilaria sinensis. On one hand, detection sample capacity is small, and structural morphologies of wood and wood finished products cannot be damaged; and on the other hand, proper DNA (deoxyribonucleic acid) information of the wood serves as a basis, and a species identification result of the aquilaria sinensis can be obtained quickly, accurately and objectively, the shortcoming that the traditional identifying method is necessarily established on the basis that detected wood has a complete morphological structure which is easy to recognize is overcome, and detection of the aquilaria sinensis has high specificity and high sensitivity.
