摘要

Based on the study of parse wood materials, the fitting empirical equation of tree growth was obtained, a function with tree growth as a variable and time as an independent variable. Through mathematical operations such as function derivation, the mature age of tree growth was obtained, and the obtained expected mature age of Saliz matsudana was 21 a. And the application, research directions and precautions of the mature ages were proposed.
