The invention relates to a broad-leaved wood board gum-removing and drying integrated treatment method. According to the broad-leaved wood board gum-removing and drying integrated treatment method, a broad-leaved wood board is placed in a lumber kiln. The broad-leaved wood board gum-removing and drying integrated treatment method comprises the following steps: (1) setting dry-bulb temperature to increase to 90+/-3 DEG C from room temperature and relative humidity to increase to 93+/-3%, and carrying out gum removal on the broad-leaved wood board repeatedly so that lumber gum is oozed to be coagulated on lumber surface; and (2) setting medium state to have dry-bulb temperature of 65 DEG C and relative humidity of 82%, and carrying out a plurality of stages of drying treatment processes so that the moisture content of wood is 8%-10%. High temperature high humidity-low temperature low humidity circular treatment is adopted in the lumber drying pretreatment stage, treatment time and treatment period of each stage can be adjusted in different dry-bulb temperature and relative humidity states so that the purpose of removing gum of lumber is achieved in pretreatment stage, gum of lumber is basically removed through drying, and percent of pass of lumber after oil paint reaches more than 95%.
