| Abstract: | 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. |
