The invention relates to a complex wood bundle, complex recombinant wood and a preparation method thereof, and belongs to the technical field of wood processing. The preparation method of the complexwood bundle comprises the following steps: step 1, preparing a proper amount of wood bundles; step 2, introducing plant polyphenols into the wood bundles to obtain polyphenol wood bundles; step 3, introducing metal salt into the polyphenol wood bundles to obtain polyphenol metal salt wood bundles; and step 4, drying the polyphenol metal salt wood bundles to obtain the complex wood bundle. By the complex recombined wood prepared from the complex wood bundle, the problems that the recombined wood in the prior art is prone to wire skipping, deformation, cracking and the like are solved, and goodmechanical properties are maintained.
