Abstract: The experiment was conducted to study the fertilization on vegetative and reproductive growth of Dalbergia odorifera, and then provide useful suggestions for plantation management. The effects of Nitrogen(N, 185.6 g N per tree), Phosphorus(P, 120 g P₂O₅ per tree), Potassium(K, 120 g K₂O per tree) as well as their mixtures(PK, 120 g P₂O₅ mixed with 120 g K₂O per tree; NPK, 185.6 g N mixed with 120 g P₂O₅ and 120 g K₂O per tree) on leaf growth, branch development, inflorescences set and biomass accumulation of a 8-year-old D.odorifera plantation were studied. There were significant differences on vegetative and reproductive growth of D.odorifera among these treatments(P<0.05). Nitrogen(N) treatment was helpful for vegetative growth of D.odorifera, and suitable for large-timber forest cultivation, because the ratio of vegetative branch, leaf number and leaflet width of vegetative branches were increased by 40.25%, 21.75% and 9.52%, and the inflorescence diameter and biomass were decreased by 12.75% and 48.63%, respectively. While P and P mixed with K were more appropriated for breeding purpose, because the ratio of vegetative branch was decreased by 47.96% and 46.84%, respectively. When N, P and K were mixed together(NPK), the vegetative and reproductive growth were both enhanced significantly(P<0.05), because the ratio of vegetative branch, length of vegetative branch, leaf number, leaflet length, leaflet width, branch biomass, inflorescence number and inflorescence biomass were increased by 26.04%, 68.16%, 32.98%, 15.20%, 11.40%, 83.60%, 54.20% and 49.84%, respectively. Thus, the vegetative and reproductive growth of D.odorifera can be regulated though formula fertilization(biased to N or P and K).
