Abstract: A field experiment was conducted in a nursery of Zhoushan Forestry Institute in 2013 to compare the effects of different fertilization strategies \[i.e. no fertilization (CK), onetime fertilization (DF), linear fertilization (LF), average fertilization (AF) and exponential fertilization (EF)\] on growth and nutritional characteristics of M. thunbergii seedlings. The results showed that the treatment effect on plant height, ground diameter and biomass followed the order of EF>AF>LF>DF>CK. The height and basal diameter in EF treatment were significantly higher than in DF and CK (P<0.05), the total biomass and the nutrient contents in EF treatment were higher than in the other four treatments, but there was no significant difference between AF, LF and DF. As compared to DF, LF and AF, fertilizer efficiency by EF increased by 0.89, 1.42 and 1.73 times, respectively.
