| 摘 要： | 通过白桂木播种育苗，研究白桂木1年生苗在苗期的生长规律。经定期观测和回归分析，模拟苗木生长与时间的数学模型。结果表明：采用有序样品聚类法将生长期划分为3个时期：生长初期、生长盛期、生长后期，生长盛期生长量占总生长量的60％-70％；用幂函数模型来模拟白桂木1年生苗各生长时期苗高和地径的生长情况的相关系数和拟合度最高。

| Abstract: | Growth rule of one-year-old seedlings of Artocarpus hypargyreus Hance was studied. The mathematical model of eorrelativity between the growth quantity and growth time was established by means of stable measurement and regression analysis. The results indicated that the growth process of seedling could be divided into four stages： early growth stage, rapid growth stage and late growth stage, the growth quantity of rapid growth stage accounted for the total growth 60%-70%. The relationship among height, ground diameter and growth time could be best described by the power model （y：αt^b）. |
