摘　　要：白木香是我国珍贵树种,以1.5年生的白木香幼苗作为实验对象,对照CK、复合肥N_1、叶面肥N_2以及根肥N_3,采用四种不同的施肥处理方式对其进行试验,观察白木香幼苗生理生长的变化。研究发现,通过对照组比较,得出不同施肥方式对枝下高生长有促进作用、地径以及株高的生长,在利用复合肥N_1处理30天后,白木香幼苗的枝下高以及植株高均有较大幅度的增长,且差异显著(P<0.05);除N_1处理90天后的SPAD、叶片含水量、叶片氮含量略有降低,叶面肥N_2以及根肥N_3的处理均高于对照CK。Aquilaria sinensis is precious tree species in China for the 15A year of Aquilaria sinensis seedlings as the experimental object. The control of CK and N1 compound fertilizer and foliar fertilizer N2 and fertilizer root N3 by using four different fertilizer processing on the test to observe the change of Aquilaria sinensis seedling physiological growth. The study found that the control group for the different fertilization methods on heightunderbranch promoted growth, diameter and height growth in the use of fertilizer N1 treatment after 30 days of Aquilaria sinensis. Seed- lings under branch height and plant height were greatly increased and the difference was significant （P 〈 0. 05 in addition to SPAD, N1 ） ; after 90 days of treatment of leaf water content, leaf nitrogen content decreased slightly, foliar fertilizer N2 and fertilizer N3 root were higher than that of control CK.
