The invention mainly relates to the technical field of wood product processing, and discloses a wicker softening treatment method, including: wicker soaking, primary drying, wicker enzymatic hydrolysis, secondary drying, wicker fermentation, wicker ultrasonication, and triple drying; the method is simple and easy to operate , safe and healthy, does not contain any toxic chemical reagents, does not use high temperature in the process, saves energy, protects the environment, and saves processing costs. The traces of treatment increase the application value of willow and increase the economic income by 9.2%; the willow bark is bundled after harvesting, and the willow bark is retained for processing together with the willow bark. Protective effect, avoiding traces after treatment, soaking in alcohol solution after binding, can not only kill bacteria and insects, but also increase the intercellular moisture of wicker and soften wicker fibers.
