摘要
在湖北省西部山区的宜昌市夷陵区进行了21个杨树无性系的造林试验。7年的调查结果表明,只要品种选择合适,杨树可以在山地生长,且速生、经济效益显著。‘鲁山’杨、‘M81-18’杨、‘351’杨、‘375’杨、‘中汉17号’5个优良无性系生长性状优良且稳定,不仅适合超短轮伐期经营,也适合中短轮伐期经营及短轮伐期经营。‘中嘉8号’、‘中嘉5号’、‘中监1号’、‘中监3号’、‘天演’杨、‘辽河’杨、‘108’杨的造林存活率低或者长势差,不宜在该山区推广应用。研究结果为湖北省西部山区营建杨树人工林提供了优良品种选择依据。
The afforestation experiment of 21 poplar clones was conducted in Yiling District of Yichang City located in the western mountain areas of Hubei. The results showed that the five clones including clone ＇ Lushan＇ , clone ＇M81-18＇ , clone ＇351 ＇ , clone ＇375＇ and clone ＇ Zhonghan-17＇ were of excellent characteristics in growth and stable in the areas and not only suitable for intensive short-rotation plantation but also suitable for Short-rotation plantation. However, 7 clones of 21 clones including clone ＇ Zhongjia-8＇ , clone ＇ Zhongjia-5 ＇ , clone ＇ Zhon^ian-1 ＇ , clone ＇ Zhongiian-3 ＇ , clone ＇ Tian- yan＇ , clone ＇ Liaohe＇ and clone ＇ 108＇ were unsuitable for their lower survival rate and slow growth. The results provided a good basis for the selection of superior poplar clones in the western mountain areas of the Hubei.
