Abstract [Objective ] The most suitahle fertilizers and the application levels for container seedlings of Michelia
macclarei Dandy were explored to provide technical support for cultivation of high-quality seedlings of the specie
(Method The experiments were design
pure yell(w su
nd the treatments were pure yellow subsoil supplementing with slow-release Fertilizers (SRF) al levels of 0. 2%
0.4%,0.6%,0.8 and 1.0%, or with compound fertilizer(C) at levels of 0.3%, 0.5%,0.7% and 0.9%. Height, basal
diameter, chlorophyll content, biomass and survival rate of the seedlings were measured to evaluate the quality af
seedlings through Principal Componen Analysis(PCA [ Result Both SRF and Cfcould promote seedling growth
height, basal diameter, relative chlorophyll content and biomass increments, and the effects of Sitf'were better than those
seedlings A comprehensive ase men of seelng quality vealed a reatment 3(SRF.6)performed best. Generally
speaking, treatments adding SRF or CF grew better than the control, and SRF applieations were superior to Cf'treat-
ments. Conclusion For he cultivalion f M. marei container seedlings, applicalion of 0.6%RF in the substrate
is strongly recommended
