The pulping and papermaking properties of Guangxi pinus massoniana aged 5-15 were studied under the same cooking and beating conditions.The results showed that the yield of cooked fine pulp of pinus massoniana of 12 years was the highest,followed by 10 years.The average fiber length of pinus massoniana of several ages was more than 1.9 mm,and the draw ratio was higher than 59.The 10 years old pinus massoniana handsheets had a higher tensile index and burst index,and was superior to the natural pine pulp produced by a certain company using imported pine wood as raw material.It indicated that the 10 years old Guangxi pinus massoniana can be used for pulping and has good performance indicators.
