本文分析了引种的 7个三倍体毛白杨系号在河西走廊的适应性。结果表明 :供试的 7个三倍体毛白杨系号 (BT85、B10 0 8、A12 9、A12 8、A12 2、B330、BM18)在土壤贫瘠、中度盐渍化的土壤上能正常生长 ,树高、胸径年增长量是当地乡土树种二白杨的数倍至数十倍 ,可作为温度较高的同类地区造林的主要树种。供试的 7个三倍体毛白杨系号中BT85抗冻性较强 ,基本上能够安全越冬 ,可作为河西走廊绿洲内部造林的主要树种之一 ,B10 0 8在有林带庇护小气候的区域内造林可望获得成功
In this paper, we analyzed the adaptability of the introduced 7 triploid Populus tomentosa in the Hexi Corridor. The results showed that 7 triploid Populus tomentosa cultivars (BT85, B10 0 8, A12 9, A12 8, A12 2, B330, BM18) were able to grow normally in poor and moderately saline soils, The tree height and DBH annual increment are several times to ten times that of the local native Populus tomentosa and can be used as the main tree species for afforestation in similar areas with higher temperature. Among the 7 triploid Populus tomentosa strains tested, BT85 is highly frost-resistant and can basically be safely winter-winded. It can be used as one of the major tree species afforestation in the Hexi Corridor oasis. B10 0 8 Afforestation in a sheltered microclimate belt Expected to be successful
