乌盟广大群众很早就在庭院和村旁栽植榆树,近年来它已成为后山地区营造‘三北’防护林的先锋树种。但前山地区有相当一部分群众认为榆树不如杨树生长快,因而发展缓慢,有林面积所占比例很少。其实,榆树是一个优质、速生、抗逆性强的树种,不仅生长量可与杨树媲美,其适应性则大大优于杨树。

In fact, elm tree is a high-quality, fast-growing, strong resistance species, not only growth can be comparable with poplar, its adaptability is much better than poplar.
