摘要
以高等数学的有关理论，通过Ｌｏｇｉｓｔｉｃ方程对加拿大杨、紫穗槐、刺槐、沙棘等４种苗木的生长规律进行了模拟研究，并对速生期进行重点分析。提出了苗木大量供应水肥的起始时间，为苗木科学管理提供了理论和方法。
The growth regulation of nursery stocks of four tree species, Canadian poplar, Amorpha, Black locust, Sar-buckthorn, were simulated with logistic equation and their quick-growing period were analyzed. The authors suggested theoretically the start and end date of large amount irrigation and fertilization for practical management of nursery stocks.
