摘　　要：在干旱年份，从科尔沁沙地干燥沙丘选择特别耐旱的灌木树种进行育苗试验。通过对1、2年生苗木生长状况分析：叶底珠（Securinega suffruticosa）、鼠李（Rhamnus porflorus）、桃叶卫矛（Evonyms bungeanus）、驼绒蒿（Eurotia arborescens）和杠柳（Periplocasepium）等适应性强，1年生苗木高度为对照树种胡枝子的49．6％～101．8％，2年生苗木为对照树种胡枝子的89．0％～97．9％，可以进一步进行沙地造林试验；东北木蓼生长缓慢，不宜继续进行造林试验。Seedling-raising experiments of drought enduring shrub species on dry dunes in Horqin steppe were conducted. A- daptability of 1 or 2-year-old seedlings of Securinega suffruticosa ,Rhamnus pogqorus ,Evonymus bungeanus ,Eurotia arboresceru, Periploca sepium are stronger. Height of 1 -year -old seedling is 49.6% -101.8% of Lespedeza bicolor. Height of 2-year -old seedling is 89.0%-97.9% of Lespedeza bicolor and can be planted on steppe. Atraphaxis manshurica grows slow and can＇ t be suitable to be planted.
