摘要
采取“全根法”进行了杜仲根系的调查 ,揭示了杜仲的生长特点。同时 ,应用多种数学模型进行相关分析 ,建立杜仲地下部分生长与地上各部分之间的回归相关模型 。
The growth characteristics of eucommia were expounded with the whole-root method, with a view to identifying the relationship between the aboveground growth and the underground growth. From correlational analysis with mathematical models, several regressional formulas were derived that could be useful in estimating the growth of this medicinal plant under certain site conditions.
