摘　　要：丹红杨是中国林业科学研究院2003年培育成功的新一代超速生抗虫杨,雌株。耐桑天牛、易生根、速生(年胸径生长量达5.8 cm,年平均高生长量4.9 m)。为了提高丹红杨的造林成活率,进行了杨树插干深栽造林试验。试验结果表明,丹红杨采用插干深栽造林方法与传统的带根植苗造林相比,具有成本低、成活率高、生长量大等特点,是一种比较经济、安全、高效的杨树造林方法,适宜在中原地区大面积推广。Populus deltoides CL.＇Dan Hong＇which is a successful new-generation superfast-speed pest-resistant poplar,being female plants,were cultivated by Chinese Academy of Forestry in 2003;it is resistant to mulberry beetles,easy to root,fast-growing（annual DBH increment being 5.8 cm,and annual average height growth being 4.9 m）.In order to improve the survival rate of Populus deltoides CL.＇Dan Hong＇,deep planting experiment with direct slip was conducted.Result shows that： compared with the traditional afforestation by seedling with complete root,Populus deltoides CL.＇Dan Hong＇ which takes afforestation method of deep planting with trunks,have characteristics of low-cost,high survival rate,large growth;it is a more economical,safe efficient poplar silvicultural method and should be spreaded in large area of central plains region.
