摘　　要：Objective] In order to improve the survival rate of Hippophae rhamnoides hardwood cuttings, cultivate high-quality sea buckthorn seedlings. [Method] This pa-per took hard branches of Russian big fruit H. rhamnoides as material. The days of striking roots, rate of striking roots,root length and number of adventitious root were determined. [Result] The cuttings col ected from upper treetops were obviously inferi-or to the lower ones. Three years cutting is obviously better than one or two years. Cuttings from lower branches were not so good as the cuttings from upper branch-es. Base oblique incisions were clearly superior to paper-cover incision. The optimal length of cuttings was 20-25 cm. The rooting rate of cuttings was the highest by fast dipping with NAA of 50 mg/L. [Conclusion] The study provides theoretical basis for H. rhamnoides artificial cultivation.[目的]提高沙棘硬枝扦插成活率，培育优质沙棘苗木。[方法]以俄罗斯大果沙棘硬枝为材料，设计不同采条部位、插穗年龄、插穗长度、下切口方式、扦插基质、药剂等处理进行沙棘硬枝扦插试验，测定和分析了不同处理的硬枝插穗生根天数、生根率、不定根长度、不定根数量4个指标。[结果]采自树冠上部的插穗生长明显劣于来自树冠中、下部插穗，3年生插穗明显优于1、2年生插穗，枝条下部不及枝条上部插穗，插穗基部斜切口优于平切口，20～25 cm插穗较优用50 mg/L NAA速蘸，插穗生根率最高，达80．67%。[结论]该研究为大果沙棘人工栽培提供理论依据。
