越南二倍体与四倍体马占相思树(Mangium)的纤维和纸浆性能比较本文研究了6个二倍体和5个四倍体的8年生马占相思树(Mangium)的制浆性能和纤维特性。每个树种取样2个或3个。虽然二倍体与四倍体树种在采用硫酸盐法蒸煮到卡伯值20时的制浆得率非常接近,但与二倍体树种的纸浆纤维尺寸(长683μm,宽15.6μm)相比,四倍体树种的纸浆纤维明显更长(883μm)和更宽(20.0μm)。四倍体树种的细胞壁更厚,因而纤维粗度更大。虽然四倍体树种的纤维黏合面积较
Comparison of fiber and pulp properties of diploid and tetraploid Mangium in Vietnam This paper studied the pulping performance of mangium with 6 diploids and 5 tetraploids, Fiber properties. Take 2 or 3 samples for each tree species. Although the rates of pulping of diploid and tetraploid species are quite similar to those of kraft pulp with a kappa number of 20, compared with the pulp fiber size of diploid tree species (683 μm in length and 15.6 μm in width) The tetraploid tree pulp fibers were significantly longer (883 μm) and wider (20.0 μm). Tetraploid trees have a thicker cell wall and thus a greater fiber thickness. Although tetraploid tree fiber bonding area than
