为了选出适合于丹东地区的速生杨品种,于2003年春开始,在东港市、凤城市、岫岩县三地交界大洋河河畔砖瓦窑村进行了不同速生杨的栽培试验。到2013年,通过对杨树调查与分析,总结出杨树10a栽培试验结论:(1)迎春5号、中黑防、辽育杨有较强抗病虫害、抗低温特性,树高、胸径生长性能也较好,综合表现优于其他品种。(2)中林系杨、新疆杨生长特性优于其他品种,但保存率偏低,具有一定抗病虫、抗低温冻害能力。(3)3930杨、308杨、127杨、108杨、128杨,虽生长指标不错,但保存率很低,抗病虫、冻害能力差。
In order to select the poplar varieties suitable for Dandong, different poplar cultivation experiments were carried out in the brick and tile kiln village along Dayang River at the junction of Donggang, Fengcheng and Xiuyan counties in spring 2003. By 2013, through the investigation and analysis of poplar, the poplar 10a cultivation experiment conclusion is concluded: (1) Yingchun 5, Zhonghei and LiaoYuang have strong resistance to pests and diseases, low temperature resistance, tree height and DBH growth Performance is better, the overall performance is better than other varieties. (2) The middle forest forest poplar and the Xinjiang poplar forest have better growth characteristics than the other cultivars, but the preservation rate is low, and they have the ability of resistance to diseases, pests and frost.
