摘要： 本文对马尾松全树材性的纤维形态、细胞壁S_2层的纤丝角、纤维素相对结晶度、化学组分、气干密度、生长轮宽度、晚材率、干缩、吸水性、硬度及纸张的强度进行了比较研究。纤维长度以根材最长(E:4269μm,L:4297μm),其次为干材(3357μm,3564μm)及梢材(2675μm,3224μm),枝材最短(2575μm,2700μm)。抄片纸的强度以干材和根材浆较好,其次为梢材和枝材;根材的撕裂强度最好。

Abstract: The Whole-tree wood properties of Pinus massoniana Lamb., such as fiber form, fibril angles of the Sz layer of tracheids secondary wall, the relative crystallinity of the cellulose, chemical composition, density, shrinkage、hardness of air-dried wood, Width of growth rings, late wood percentage, and water absorbability were studied. The characteristics of paper sheets made from the wood were investigated also.In the different parts of tree the rootwood have the longest fiber (E:4269μm, L:4297μm), next are those in total bole-wood (3357μm, 3564μm) and unmerchantable top-wood (2675μm, 3224μm),and the shortest ones (2575μm, 2700μm) are in branch-wood.The paper sheets made from the pulp of total bole-wood and root-wood have better strength than that of unmerchantable topwood and branch-wood. The best tear strength was found in the paper sheets made from pulp of root-wood. It proves that with suitable technology the whole-tree wood of Pinus massoniana for making bag paper is quite feasible.
