The invention discloses a preparation method of a high-yield camellia oleifera shell pulp. The preparation method of the high-yield camellia oleifera shell pulp specifically comprises the steps of mechanical grinding, pre-impregnation, mechanical disc grinding treatment, washing, defibering and screening. The preparation method prepares the high-yield camellia oleifera shell pulp through a chemical and mechanical method; the prepared high-yield camellia oleifera shell pulp has the advantages of being high in yield, good in pulping performance and drainability and the like and can be applied tothe fields of paper-based packaging, molding and decorating materials and the like, thereby to some extent easing the stress brought about by shortage in papermaking fiber resources. Besides, a largenumber of waste camellia oleifera shells are applied to the fields of pulping and papermaking to achieve efficient and high-value application of agricultural waste.
