摘　　要：对7个沙棘品种苗期生长动态进行研究的结果表明:各品种幼苗的苗高和叶片数的前期生长量要快于后期生长量,苗高和叶片数半月生长量中最高的是契切克,其次为壮圆黄;叶片数半月生长量中最低的是丘依斯克;以不同品种沙棘苗高半月净生长量为指标,采用有序样本聚类分析将沙棘苗高生长过程划分为4个时期:出苗期、幼苗期、速生期和生长后期,其中,速生期苗高生长量最大,其次为幼苗期,出苗期和生长后期生长量最低。The grow dynamics in seedling period of 7 sea buckthorn varieties were studied. The results showed that the seedling height and number of leaves early growth were faster than the latter part of the growth in 7 sea buckthorn varieties. The maximum growth of seedling height and numbers of leaves in15days was QiQieke,and followed by ZhuangYuanhuang. The lowest growth of numbers of leaves in15days was Qiuyisike. The height growth process of 7 sea buckthorn seedlings was divided into four stages with the sequential sample cluster analysis,taking the height net growth increment of 7 sea buckthorn seedlings as samples： emergence stage,early growth stage, rapid growth stage and late growth stage,and height growth was maximum in rapid growth stage,followed by early growth stage,the lowest growth at emergence stage and late growth stage.
