The invention discloses an agrobacterium tumefaciens gene transformation method of hybrid poplar. The method comprises the following steps of: (1) pre-culture; (2) strain activation and culture; (3) infection; (4) co-culture; (5) delayed selection; (5) adventitious bud induction; (7) extension culture; and (8) root induction and detection. In the method provided by the invention, NAA and 2ip act together to induce the agrobacterium tumefaciens-mediated stem section or leaf stalk to generate callus; under the effect of cytokinin TDZ, the callus redifferentiation is promoted to form adventitious buds; the bud in a vitrified state extends under the induction of BAP (Benzo A Pyrene), and the form gradually becomes normal; and the resistant regenerated poplar roots in a 1/2MS (Murashige and Skoog) culture medium containing antibiotic hygromycin. The resistant genetically-modified poplar obtained by the method has the advantages of short period and high transformation efficiency, thereby laying firm foundation and theoretical support for the practical breeding of the genetically-modified poplar.
