摘　　要：通过对1年生岗梅Ilex asprella幼苗苗高和地径生长过程进行定期跟踪观察、调查,岗梅幼苗苗高及地径生长曲线均呈“S”形,快速生长阶段均集中在5-8月份之间。苗高与地径均有两次高峰生长阶段,分别在6月和7月。8月开始苗高和地径增长速度逐渐减缓,进入11月生长缓慢,直至12月份基本停止生长。苗高和地径的生长量均符合拟合Logistic曲线方程的生长规律。根据岗梅幼苗生长特点,幼苗生长过程可划分为5个生长阶段:萌动期、出苗期、生长早期、生长盛期、生长后期。Through regular follow-up observation and investigation of the growth process of 1-year-old Ilex asprella seedlings,the growth curve of seedling height and ground diameter of I.asprella was"S"shaped,and the rapid growth stages were concentrated between May and August.There were two peak growth stages of seedling height and ground diameter in June and July respectively.The growth rate of seedling height and ground diameter gradually slowed down from August,and the growth rate slowed down from November until December when growth stops.The growth of seedling height and ground diameter conformed to the growth law of fitting the logistic curve equation.According to the characteristics of seedling growth of I.asprella,the seedling growth process can be divided into five growth stages:the Germination stage,Emergence stage,Early growth,Active growth stage,and Late growth stage.
