杉木幼林中混交泡桐年生长动态的研究

Study on Annual Growth Performance of Paulownia imperials Mixed with Chinese Fir

本文对杉木幼林中混交泡桐的年生长进行逐月调查，并进行幼林管理和幼林生长动态的LOgistic模型拟合，以研究泡桐年生长中的速生期，生长极大值最大点，为泡桐生产和管理提供理论依据．

Through monthly investigations on large sapling of Paulownia imperials stands mixed with Chinese fir, the annual growth performance was fitted by the means of Logistic model in this paper, then the fastgrowing stage and maximum increment point within one year were determined with the aid of the model. Thisstudy would provide a theoretical basis on the production and management of Paulownia imperials.
