Method for non-destructively identifying tree species of red wood products

The invention relates to a method for non-destructively identifying tree species of red wood products, and belongs to the technical field of gas sampling and testing. The method comprises the following steps: firstly, establishing a smell library of various rosewood smells, then selecting any rosewood smell olfactory source and combining with an identification tank for repeated training, and training a dog to actively complete an identification process: firstly actively deeply olfactory the olfactory source, then orderly smelling and recognizing the identification tank, and finally giving an alarm. And then the dog actively and smoothly completes the identification process through various smell training. When actual redwood identification operation is carried out, the soft adsorption material is used for rubbing the surface of the redwood product to adsorb the smell of the redwood product as a detected smelly source, and a dog smells the detected smelly source, finds out the corresponding smell in the redwood
