摘　　要：研究南方红豆杉(Taxus chinensis var.mairei)1年生裸根苗在苗期各个器官生长的变化规律,模拟苗木各器官生长与时间之间的相关关系和各器官生长与苗高生长的数学模型,结果表明:南方红豆杉1年生苗出现2次生长高峰期和1次生长缓慢期,4-6月为第1次生长高峰期,7-9月为生长缓慢期,10-11月为第2次生长高峰期;苗高、地径与生长时间呈y=atb的幂函数关系,根、径同苗高的生长有着直线型的相关关系;拟合模型符合该树种1年生苗的生长规律,各器官间的数学模型及相关关系均达到极显著水平。Growth rhythm of bare-rooted 1-year seedling of Taxus chinensis var. mairei was observed in Lishui, Zhejiang province. Models weresimulated for growth of each organ with time and with seedling height growth. The result demonstrated that two growth peaks occurred respectivelyduring April to June and during October to November, and a poor growth period was during July to September. Seedling height, ground diameter hadpower function relation with time, y = atb, root and stem had linear correlation with height growth. Models were fitted with growth rhythm of 1-yearseedling.
