摘　　要：胡杨是干旱大陆性气候环境条件下的树种,原始分布地的自然环境条件与陕北相似,榆林市的定边县和靖边县有零星分布,但数量很少,仅存50余株。为了改善榆林沙区树种结构,丰富园林绿化树种,保护濒危物种资源,对胡杨进行引种繁育,开展播种育苗技术研究,总结胡杨在榆林沙地的育苗技术,扩大胡杨栽植范围,对于增加沙地生物多样性,提高沙区生态治理水平具有重要意义。Populus euphratica(POPULus euphratica)is a tree species in arid continental climate environment.The natural en⁃vironment conditions of the original distribution area are similar to that of northern Shaanxi province.There are scattered distri⁃bution in Dingbian county and Jingbian County of Yulin City,but the number is very small,only more than 50 plants remain.In order to improve the yulin sandy tree structure,rich garden greening tree species,protect the endangered species resources,ar⁃tificial breeding of p.euphratica planting seedling technique study,summarizes the Euphrates poplar seedling technique in yulin sandy land,expand the scope of populus euphratica planting,to increase the sand biodiversity,raise the level of its eco⁃logical governance is of great significance.
