摘　　要：研究了青钱柳1a生苗的年生长节律,结果表明Logistic方程拟合苗木生长节律效果良好;并将其生长期划分为出苗期(5月15日以前)、生长初期(5月16日～7月6日)、速生期(7月7日～9月26日)和生长后期(9月27日～11月20日),速生期内的净生长量占总生长量的60%左右。Growth rhythm of Cyclocarya paliurus one-year-old seedlings was studied in the paper. The results showed that the Growth patterns of Cyclocarya paliurus seedlings could be simulated by Logistic equation. And the integral growth could be divided into four stages, which were emergence stage （before May 15 ）, young seedling stage （May 16 to July 6）, fastgrowing stage （July 7 to September 26） and late-growing stage （ September 27 to November 20）. The production of the seedlings in the fast-growing stage was approximately 60% of the total production.
