摘要
以１年生泡桐埋根苗为对象，研究苗木年生长规律。采用Ｇｏｍｐｅｒｔｚ方程和Ｌｏｇｉｓｔｉｃ方程模拟高生长进程，结果表明；泡桐幼苗１年内高的生长呈Ｌｏｇｉｓｔｉｃ型曲线；生长最佳回归方程可用１条双Ｌｏｇｉｓｔｉｃ曲线表示；速生期约在７月１０日至８月１５日之间。
The height growing process of 1-year-old root cutting of Paulownia was simulated with Gompertz and Logistic equations. The results indicated that the height growting within on year accorded with the logistic curve, the best regression curve could he defined as a double logistic curve, and the fast growing period of Paulownia root-cutting of 1-year old was between July 10 and August 15.
