摘　　要：按随机区组设计,利用不同浓度GGR6号,浸泡不同品种沙棘种子,结果表明,GGR浓度为30mg.kg-1时,供试的三个品种出苗率最高,对沙棘的株高、根幅、根径粗、新枝生长量的促进作用最为明显。GGR6号浸泡沙棘种子后,对中华沙棘品种促进作用最好,向阳、楚伊次之。By randomized block design, using different concentrations of GGR6, soak different varieties of Sarch seed, their emergence and growth were tested. The results showed application of GGR concentration of 3mg·kg^-1, tested three varieties were the highest germination rate, the height of Sarch, roots range, root diameter thick, new branches growth promoting role were the most significant. The variety of Zhonghua was promoted the best by GGR6 soaking Sarch seed, Xiangyang and Chuyi were the second.
