The invention discloses a long-distance tree transport method. The trees are transported by adopting containers with temperature and humidity regulation devices. Bryophytes are uniformly coated on thesurfaces of tree soil balls and trunks, and environmental conditions suitable for bryophyte growth are created, so that water evaporation of the roots and trunks is reduced, and the water balance between an overground part and an underground part is maintained. According to the method, the trees can be transported for a long distance for 30 days or longer, the tree transplantation survival rate is 95% or higher, the engineering cost can be reduced, and the aim of rapidly improving the urban landscaping and ecological benefits can be achieved. According to the long-distance tree transport method disclosed by the invention, due to own treatment of the trees, by controlling the environmental conditions in the containers, the trees can be transported in a long distance under the condition of10-15 DEG C, low temperature damage is avoided, and the method is low in energy consumption and environmental-friendly.
