摘要
将收集到的20个杨树优良无性系,在湖北省长江中游平原地区的监利县进行了造林对比试验。通过10 a的试验选出适宜在湖北省长江中游平原栽培的长江杨、鲁山杨、303杨、中汉17、375杨5个优良无性系。以材积为主要参考指标,所选出的优良无性系生长量比对照提高20%以上。本试验为湖北省长江中游平原地区杨树人工林经营提供了无性系选择依据。
We carried out the afforestation experiment of 20 poplar clones in Jianli district of which lies in plain area of Hubei. Through 10 years of testing, 5 clones including Yangtze Populus, Lushan Populus, 303 Populus, Zhonghan-17 Populus, 375 Populus were selected as the superior clones fit for extending in the plain of the mid-Yangtze river. Judging from volume, the volume growth of selected clones had increased by 20% compared with CK. So this study provided a clone selection basis for the poplar scientific cultivation in the plain of the mid-Yangtze river of Hubei Province.
