摘要
对华北落叶松1年生播种茁苗高、地径、根长生长规律的研究结果表明，利用Logistic曲线方程能够很好的对生长进程进行拟合，相关系数均大于0．95，显著水平达到0．0001。有序样本聚类分析显示，苗高生长盛期为7月15日～9月15日，地径生长盛期为8月25日～9月25日，根长生长盛期为7月25日～9月25日。
The yearly growth regularity of height,diameter and root length was studied of One-year-old seedlings of Larix principis-rupprechtii.The growth pattems can be fitted well with the Logistic curve equation;the correlation coefficient （R2） were greater than 0.95, and the significant level of P were 0.0001. Based on the ordered sample cluster analysis, the fast-growth period of height was July 15th to September 15th, the diameter was August 25th to September 25th, and the root length was July 25th to September 25th.
