摘要
在四川省资中县集约栽培的试验林内采集了泡桐无性系CO20和泡桐各五株进行了多项试验研究。证实了泡桐无性系CO20的木材纤维长度、微纤丝角和纤维素的相对结晶度优于泡桐;综纤维素、α-纤维素以及木材物理力学的主要性能指标低于泡桐。制浆得率低。浆张物理性能接近或燬过两种相思树木材指标。
In an experimental stand of intensive management in Zhizhong County, Sichuan Province, plants of Paulownia clone C020 and 5 Paulownia check plants were collected for the studies. Through experiments of many items, the results showed that the length of the wood fibre and the relative crystallization degree of cellulose and microfibrillar angle are better than those of the checks. But the holocellulose and alpha cellulose of its chemical components and the main indices of strength properties of wood are lower than those of the checks. Its yield rate of pulp-making is low When a comparison of the physical properties of its sheet pulp with those of 2 Acacia spp. is made, the result shows that the former is close to or better than the latter.
