摘　　要：应用有序样本聚类分析法将云南樟Cinnamomumglanduliferum1年生播种苗苗高生长过程分为4个时期:出苗期为3月12日～5月13日,生长初期为5月14日～7月15日;速生期为7月16日～9月15日;生长后期为9月16日～11月15日。云南樟1年生苗苗高、地径生长量最大值出现的时期不一致,苗高最大生长量出现在速生期,而地径最大生长量出现在生长后期。同时还对苗木的生物量积累规律、各生长指标的相关关系进行了分析,并针对苗木各时期生长特点提出了相应的培育技术建议。Sequence sample cluster analysis is used to divide the height growth process of the annul Cinnamomum glanduliferum seedlings. The results indicated that the height growth process of seedlings can be divided into four stages: juvenile stage (March 12-May 13),early growth stage(May 14-July 15),rapid growth stage(July 16-September 15) and late growth stage (September 16-November 15). The periods of maximum growth of height and diameter were inconsistent, the period of maximum growth of height was in rapid growth stage, while the period of maximum growth of diameter was in late growth stage. The biomass accumulation and the relationship between growth indices of seedlings were analyzed. According to the growth characteristics of seedlings in different stages, some measures on culture of Cinnamomum glanduliferum seedlings were suggested.
