摘　　要：该文在对三倍体毛白杨的化学组成和纤维形态进行研究的基础上 ,着重进行了对其碱性亚钠 蒽醌法制浆特性的研究 .研究表明 :在相同蒸煮条件下 ,三倍体毛白杨较普通毛白杨细浆得率高 ,卡伯值低 ;浆张强度较普通毛白杨好 .三倍体毛白杨的碱性亚纳 蒽醌法浆 ,卡伯值在 18左右时 ,细浆得率达到 53 %以上 ,而且浆张强度较好 .所以 ,三倍体毛白杨是优良的纸浆材 ,而且较适合于用碱性亚纳On the basis of studying the fiber morphology and the chemical components of the triploid of Populus tomentosa, this paper concentrated on the pulp properties by AS-AQ. The result indicates that the pulp of the triploid of Populus tomentosa is higher in yield and lower in Kapper's value than that of general Populus tomentosa and its physical properties of unbreached pulp are better too. Furthermore, the pulp yield of the triploid of Populus tomentosa by AS-AQ reaches 53% when Kapper's value is about 18, and the physical properties of pulp is very good. So it is concluded that the triploid of Populus tomentosa proves to be a fine wood species from aspects of pulping and paper making and it is a good method of AS-AQ to cook the triploid of Populus tomentosa.
