The invention discloses a drying method for eucalyptus core boards and relates to the technical field of wood processing. The method includes the following steps that the eucalyptus core boards are boiled by being immersed in hot water, and then naturally air-dried for 24-32 h; the air-dried eucalyptus core boards are dried two times, specifically, as for primary drying, the drying temperature is68-75 DEG C, drying time is 2-3 h, and heat preservation is conducted for 0.5-1 h after the eucalyptus core boards are cooled to the room temperature; as for secondary drying, the drying temperature is 55-65 DEG C, drying time is 1-2 h, and the eucalyptus core boards are cooled to the room temperature until the water content is smaller than 16%; and the eucalyptus core boards are flattened througha hot press, the hot-pressed eucalyptus core boards are taken out and dried in the air for one to two days, and the finished eucalyptus core boards are obtained. The problem that the drying speed ofeucalyptus core boards in the prior art is low is solved through the drying method.
