摘要
为了筛选适宜晋南地区栽培的杨树品种,选择21个杨树优良品种,按照完全随机区组设计进行栽植,调查其年生长量、生长势以及病虫害等情况,通过对测定指标进行打分来评价杨树的生长适应性。结果表明,树高和胸径年均生长量最高的是鲁林1号、北抗1号、鲁林2号、鲁林3号。生长适应性分析表明,21个杨树品种均适宜在晋南地区栽培,其中,美洲黑杨和欧美杨品种表现良好,青杨派与黑杨派的杂交种表现一般。
To select the suitable Poplar varieties for cultivation in the south of Shanxi Province,21 Poplar varieties were selected in this research.Different Poplar varieties were planted according to the completely randomized block design which annual growth,growth potential,diseases and pests were measured and investigated.The growth adaptability of each Poplar variety was evaluated by scoring the indexes.Results showed that Lulin No.1,Beikang No.1,Lulin No.2 and Lulin No.3 had the highest annual growth of tree height and DBH.The analysis of growth adaptability showed that 21 poplar varieties were suitable for cultivation in the south of Shanxi Province.Among them,the Populus deltoides and P.deltoides×P.nigra varieties showed good performance,and the hybrids between P.cathayanaand the P.nigra showed average performance.
