Abstract:

Plantation timbers such as English Walnut, Common Jujube, Gingko, Chinese Chestnut, Camphor Tree Camphor Wood and Rubber Tree were studied on anatomical, physical, mechanical, chemical properties. The results showed that: English Walnut, Gingko and Camphor Tree Camphor Wood grew fast and exhibited good wood properties, so they could be planted mainly for timber use or for both timber and non-timber use; though Gingko and Chinese Chestnut exhibited good wood properties, they grew slowly, so they could be mainly planted for fruit use. The density and strength of English Walnut, Gingko, Camphor Tree Camphor Wood and Rubber Tree were medium,and the density and strength of Common Jujube and Chinese Chestnut were high. The cellulose content of Gingko, Camphor Tree Camphor Wood and Rubber Tree was close to Poplar, the lignin content of which was between Poplar and Masson Pine, and the morphological features of fiber conformed to the requirements for paper making, so the stem and processed residue of which could be utilized for paper making. Basic density of Common Jujube and fiber length of English Walnut could be predicted, and the results were significant.

Key words: plantation, wood properties, fiber morphology, growth ring width, physical and mechanical properties
