摘　　要：对楸树3个无性系的两类径级枝桠材的硫酸盐化学法制浆及造纸性能进行了研究。研究结果表明:粗、细枝桠材硫酸盐法蒸煮最佳用碱量分别为21%和22%(以Na2O计)。在此条件下蒸煮,可获得卡伯值为21、纸浆得率分别为41%和34%的未漂化学浆。在相同的蒸煮工艺条件下,两类径级的楸树枝桠材硫酸盐法制浆性能表现出明显的差异。楸树3个无性系枝桠材硫酸盐法制浆性能差别不十分明显,在相同蒸煮条件下所得纸浆的卡伯值、纸浆得率和筛渣率相近。8401枝桠材硫酸盐浆相对较难漂白,8402和金丝楸硫酸盐浆的可漂性相对较好。In this paper,the characteristics of kraft pulping and papermaking of the lop woods of three different clones Catalpa bungei C.A.Mey.with two diameter grades were studied.The results showed that the optimum alkali dosages for the lop wood with bigger diameter and smaller diameter are 21% and 22%,respectively.Under this cooking conditions,the unbleached kraft pulps,with kappa number of 21 and pulp yields of 41% and 34% respectively,can be obtained.With the same cooking conditions,there are obvious differences of pulping characteristics for the lop woods with two different diameter grades;however,there are no big differences in kappa number,pulp yield and reject ratio for different clones of Catalpa bungei C.A.Mey..It is relatively harder to bleach the lop wood of 8401,while the bleachabilities of 8402 and Golden Catalpa bungei C.A.Mey.lop woods are better.
