| Abstract: |
| The quadratic regression rotation composite design was used to study the effects of nitrogen，
phosphorus and potassium fertilization on the growth of Toona sinensis seedlings. The regression model among NPK
fertilizer amount and the height ground diameter and stem biomass of T. sinensis seedling was established and their
effects on seedling growth were analyzed. The effects of different fertilizers on seedling height，ground diameter
and stem biomass showed N>P>K，and the effect of potassium fertilizer on growth of T. sinensis seedlings was not
significant. When T. sinensis seedling was planted in the pot with 10 kg yellow soil，the seedling height was the
highest with 141.96 cm in the pot with 4.277 g nitrogen and 2.450 g P2O5，the seedling diameter was the widest with
16.895 mm in the pot with 4.845 g nitrogen and 2.896 g P2O5，and the seedling stem biomass was the higest with
52.529 g in the pot with 4.845 g nitrogen and 4.101 g P2O5. |
