摘　　要：为了解决荒漠地带造林难的问题,2017年引进栽植了盐柳1号、新疆杨和速生杨,对这3个树种的生长情况进行比较,以选出适宜于本地栽植的优良树种。结果表明:盐柳1号适宜在荒漠地带栽植。盐柳1号的成活率、保存率、树高、新梢生长量和胸径均优于新疆杨,新疆杨优于速生杨;施肥对盐柳1号树高和胸径生长有一定程度的影响,但对新梢长度生长影响很小,可以考虑不施肥。In order to solve afforestation difficulties in the desert area,in 2017,Salix psammophila'Yanliu-1'、Populus alba L.and Populus tomentosa Carr.were introduced and cultivated;the growth of the three tree species were compared to select the best tree species suitable for local planting.The result showed that Salix psammophila'Yanliu-1'was suitable for planting in desert zone.Survival rate,preservation rate,tree height,growth quantity of the shoots and diameter at breast height(DBH)of Salix psammophila'Yanliu-1'were better than that of Populus alba L.;and these indexes of Populus alba L.were better than that of Populus tomentosa Carr..Effect of fertilization on tree height and DBH of Salix psammophila'Yanliu-1'was definite,but negligible on growth of the shoots.Therefore,fertilization might not be considered.
