| 摘 要： | 以湖北省广泛栽培的11个杨树优良品种为研究对象，对苗圃一年生截杆幼苗用于纤维材的可行性进行了分析，对影响一年生纤维材质量的主导因素进行了评价，并对参试品种培育一年生纤维材的优劣进行了综合评定与排序。结果表明：杨树苗圃一年生幼苗的纤维形态指标与各种主要化学成分含量符合纤维材的要求，培育杨树一年生纤维材在技术指标上可行，经济上合理，并具有良好的社会基础；苗木根系年龄对纤维长度的影响很小，而品种是影响一年生纤维材质量的主导因素；中嘉2号、中潜2号、辽河杨、中嘉5号、中天1号、鲁山杨、中嘉8号及天寅杨等是一年生纤维材定向培育的较好品种。

| Abstract: | By taking the 11 improved breeds of South Poplar cultivated widely in Hubei Province as the study object,the feasibility of using one-year-old nursery seedlings without roots for fiber timber was analyzed,and the dominant factors which affected the quality of one-year-old fiber timber were evaluated,and the superiority and inferiority of the experimental breeds for cultivating one-year-old fiber timber was also evaluated comprehensively and arranged in order.The main results are as follows: Firstly,both the fiber shape indexes and the main chemical composition contents of the one-year-old seedlings in South Poplar nursery accorded with the demands of fiber timber.It is feasible in technological indexes,reasonable in economy and excellent in social basis to cultivate one-year-old South Poplar's fiber timber.Secondly,the seedling's root age had little influence on the fiber length.However,breed was a dominant factor affecting the quality of one-year-old fiber timber.Finally,there were many improved breeds for cultivating one-year-old fiber timber,such as No.2 of Zhongjia,No.2 of Zhongqian,Liaohe Poplar,No.5 of Zhongjia,No.1 of Zhongtian,Lushan Poplar,No.8 of Zhongjia,Tianyan Poplar,and so on. |
