摘要
为寻找对白毛杨生长有利的混交模式,选择榆树、刨刺槐和紫穗槐3中树种与白毛杨进行了3 a的混交实验,分析不同混交模式对白毛杨生长的影响。结果表明,白毛杨与紫穗槐混交的模式下,白毛杨的树高、胸径、单株材积和蓄积量均达到了最大值,分别为16.67 m、14.03 cm、0.116 m^(3)/株和140.01 m^(3)/hm^(2),显著高于白毛杨与榆树、白毛杨与刺槐混交模式。因此,造林时建议选择紫穗槐作为白毛杨的混交树种。这一研究结果可为杨树混交造林提供有益的参考。
In order to find the favorable mixing pattern of Populus growth,the mixing experiment of 3 middle species of Ulmus pum‐ila,Robinia pseudoacacia and Amorpha fruticosa with Populus tomentosa was carried out for 3 years,and the effects of different mixing patterns on the growth of Populus tomentosa were analyzed.The results showed that the tree height,DBH,tree volume and stock volume reached the maximum value under the mixed mode of Populus tomentosa and Amorpha fruticosa,respectively,which were significantly higher than that between Populus tomentosa and Ulmus pumila,and between Populus tomentosa and Robinia pseudoacacia.Therefore,it is suggested to choose Amorpha fruticosa as the mixed species of Populus tomentosa in afforestation.The results of this study can provide useful reference for mixed afforestation of Populus tomentosa.
