摘　　要：从乳源木莲苗高年生长曲线上看出,苗高从5月开始快速生长,7月进入速生期,7月中旬达到生长高峰,9月生长速度变缓,10月净生长量开始下降,至11月生长逐渐趋于稳定.以乳源木莲定期观测的苗高净生长量为样本,采用有序样本聚类分析将乳源木莲苗高生长过程划分为4个时期,出苗期为3月12日至4月30日,幼苗期为5月1日至6月30日,苗高速生期为7月1日至9月30日,苗木生长后期为10月1日至12月16日.根据各时期苗高的生长特点,提出了关键育苗措施,以提高成苗率、质量与产量.It is showed that its height grow rapidly from May,accelerate in July with the peak of the height growth in Jul15, and decline from Sep,and the growth stop in Decfrom the curve of the growth of height of Manglietia yuyuanensis seedlings Taking the height net growth increment of Manglietia yuyuanensis seedlings as samples,the height growth process of Manglietia yuyuanensis seedlings is divided into 4 stages by the sequential sample cluster analysis: emergence stage(May 12~Apr30), early growth stage (May 1~Jun30),rapid growth stage(Jul1~Sep30)and late growth stage (Oct1~Dec16) According to the growth of seedlings in different stages,the key managements of seedlings for cultivating is put forward to improve the rate of survival,the quality and the quantity of seedlings
