The invention relates to a degreasing and desugaring method of sympodial bamboo, which belongs to the technical field of processing and preservation of wood or similar materials. The degreasing and desugaring method is combined with the structural characteristics of the sympodial bamboo, and the two steps, namely high-temperature and high-pressure smoking and cooking, and high-temperature and high-pressure carbonization, are adopted for degreasing and desugaring the sympodial bamboo. In the step of high-temperature and high-pressure smoking and cooking, water and steam are simultaneously used for steam-boiling so as to strength the degreasing and desugaring; and in the step of high-temperature and high-pressure carbonization, the secondary degreasing and desugaring is performed on bamboo fiber, and exhaust is performed during the carbonization process multiple times, thereby removing lipids and sugars in the bamboo fiber to the greatest extent, simultaneously unifying the color of the bamboo fiber and performing the color matching on the bamboo fiber. According to the degreasing and desugaring method, simple equipment and the simple process are applied for performing the degreasing and desugaring treatment on the sympodial bamboo so as to realize anti-moth-eaten and anti-mildew effects, no preservative type substances are added during the treatment process, the high-temperature and high-pressure carbonization treatment is simultaneously adopted, the color matching can also be performed on the bamboo fiber, and the adding of a dyeing agent is not required, thereby being green and environmentally-friendly.
