本实验研究是对黑龙江省近年来引种的田菁植物原料进行化学成分的分析和纤维形态的观测。结果表明,我省产田菁主要成分的含量与山东省产田菁相差不大,含木素为14.06％,多聚戊糖14.45％、综纤维素73.61％。与芦苇等相比,木素和多聚戊糖的含量较低,而纤维素含量则相近。纤维平均长度为0.942mm,优于稻草、山杨等,与芦苇、白皮桦等相近。而且田菁秆部细胞壁较薄,壁腔比较小,作为造纸原料与同等纤维长度的其它原料相比会有较好的结合力。因此,黑龙江省产田菁作为造纸原料是适宜的,该省引种田菁必将取得较好的社会效益和经济效益。
The experimental study is to analyze the chemical composition and fiber morphology of the raw materials of Sesbania plants introduced in recent years in Heilongjiang Province. The results showed that the content of main components of Sesbania in our province was similar to that of Shandong Sesbania, with 14.06% of lignin, 14.45% of polypentose and 73.61% of holocellulose. Compared with reeds and other lignin and pentasaccharide content is low, while the cellulose content is similar. The average fiber length is 0.942mm, better than straw, aspen, etc., and reed, Betula platyphylla and other similar. And Tian Jing stalk cell wall thinner, wall cavity is relatively small, as raw materials for papermaking and other fibers of the same length compared to have better binding power. Therefore, Heilongjiang Province Tianjing as papermaking raw materials is appropriate, the introduction of the province Tianjing will achieve better social and economic benefits.
