The invention provides a method for producing high-whiteness bleached ramulus mori pulp by a caustic soda-anthraquinone continuous stewing technology. The method comprises the steps of: treating the raw material ramulus mori, continuously stewing by a caustic soda-anthraquinone method, stewing coarse pulp and screening, washing, and bleaching by CEpH or DEpD or DEpDD technology to obtain the pulp. The treatment of the raw material comprises the steps of naturally cooling, oxidizing, cracking, slicing and washing, so that the influence of the epidermis and medulla cybrid cell to the paper quality is basically and thoroughly solved, and the problem of even stewing is solved; the traditional stewing ball is replaced by continuous stewing equipment for stewing, so that the energy of an unit product can be saved by more than 40%; the step of stewing can be performed without the sodium sulphide, and the step of stewing can be performed without peculiar smell such as the hydrogen sulfide and the like, so that the method is more environment-friendly; the pulping whiteness is more than 80%; and the method is stable for industrial production on a large scale.
