Abstract: Dendrocalamus mutatus Yi et B.X. Li was selected as the research object, and the characteristics and pulping performance of Dendrocalamus mutates were studied. The application of Dendrocalamus mutatus in pulping and papermaking was studied, so as to provide more and better bamboo varieties for the high-quality development of bamboo industry in Sichuan province. The results showed that Dendrocalamus mutatus had higher biomass per unit area, wich was a high-yield bamboo species. Besides the high kappa number and viscosity, there were no other problems in the pulping experiment, which could be used to produce bamboo dissolved pulp and bamboo chemical pulp. The length of Dendrocalamus mutates fiber was longer than that of bamboo fiber for production, and the cooking difficulty was slightly higher than that of bamboo fiber for production. If Dendrocalamus mutates was used in production, it is necessary to properly strengthen the cooking conditions.
