Abstract

Fertilization with different ratios of nitrogen（N），phosphorus （P），and potassium （K），for growth physiology of Dalbergia odorifera seedlings was tested using an L9（34）orthogonal design and regression analysis. Results among the nine combinations，showed that for growth of height and diameter as well as biomass accumulation，0.45 gpot-1 N，0.30 gpot-1 P2O5 （N2P3K1） was best；for increases of chlorophyll content in leaves, N2P3K1 and 1.80 gpot-1N，0.15 gpot-1P2O5 （N3P2K1） were best；and for increases of soluble sugar content in leaves，N2P3K1 and 0.45 gpot-1 N，0.15 gpot-1 P2O5，0.6 gpot-1 K2O （N2P2K3） were best. For growth and physiology，P was most important，then K，and then N. Quadratic regression models of growth and physiology for two-year-old D. odorifera seedlings were established for N，P，and K showing suitable application amounts of N as 1.74~2.15 gpot－1，P2O5 as 2.40~2.60 gpot－1，and K2O as 0.35~0.75 gpot－1.［Ch，4 tab. 12 ref.］
