The invention discloses a production method of a nanometer wood fiber board based on a continuous hot pressing method. The production method comprises the steps of peeling and chipping, cooking and hot grinding, gluing and drying, winnowing and paving, pre-pressing and hot pressing, and saw cutting and sorting, and artificial forest fast-growing wood is processed into the fiber board. According to the production method of the nano wood fiber board based on the continuous hot-pressing method, lignin and hemicellulose can be rapidly removed based on the onlooking structure analysis of the raw material wood, targeted cooking and a hot grinding process, and meanwhile, the loss of cellulose performance is reduced as much as possible, so that the excellent mechanical property of cellulose is kept; and a continuous hot-pressing process is adopted, so that the controllability is high, different orientations of fibers can be realized, and the performance designability of the material can be effectively exerted.
