摘　　要：以水红木(Viburnum cylindricum Buch.Ham.ex D.Don)一年生播种苗为对象,对其苗高、地径的年生长规律进行了探讨。结果表明,地径与苗高的年均生长量分别为0.347、10.493 cm;地径与苗高的年生长规律均可以分为慢-快-慢3个生长阶段,其在时间上具有不同步性,地径较苗高要早进入快速生长期,但二者每个生长期的时间长短相差不大。Taking one-year-old Viburnum cylindricum Buch.Ham.ex D.Don seedings as test material,the diameter and height annual growth dynamics were studied.The results showed that the annual increment of diameter and height of were0.347 cm and 10.493 cm.The annual growth law of ground diameter and seedling height can be divided into three stages（slow-rapid-slow）,their occurrence were not synchronous,ground diameter were earlier than seedling height entered in the rapid growth period,but little difference were found in the length of each stage.
