摘　　要：我国北方寒冷干旱地区的大苗造林面临成活率及保存率不高的问题。针对这一问题,通过总结整地技术、树种选择、造林技术及造林后抚育等方面冻土坨杯苗造林技术,利用该技术进行造林,苗木土坨不散,根系不受损伤,可以大大提高北方干旱地区大苗造林成活率及保存率,适宜在北方寒冷干旱地区进行推广。The survival rate and preservation rate of large seedling afforestation in the cold and arid areas of northern China are not high.In view of this problem,through summing up the frozen soil lump seedling afforestation technology in the aspects of land preparation technology,tree species selection,afforestation technology and post afforestation tending,the use of this technology for afforestation can greatly improve the survival rate and preservation rate of large seedlings in the northern arid regions,which is suitable for promotion in the northern cold and arid regions.
