The application discloses a method for constructing a Vietnamese terminalia regenerative system, and comprises the following steps: Vietnamese terminalia stem segment test materials are obtained by grafting seedling saplings with superior branches, semi-lignified stem segments with axillary buds are used as explants, and after disinfection, the explants are inoculated into an induction culture medium to induce axillary buds, then the induced axillary buds are subjected to micro-branch cutting to carry out proliferation and rooting culture, and a large number of Vietnamese terminalia regenerative plants can be obtained. The method has the advantages of high propagation efficiency, high phenotype consistency, good genetic stability and the like, greatly shortens the production cycle of Vietnamese terminalia seedlings, reduces the variation risk of the seedlings, and provides high-quality seedlings for ecological afforestation and landscaping.
