Abstract

Plant growth requires a certain amount of trace elements.An experiment was designed in nursery in order to test the effects of Zn,Mn,and B on seedling growth of Taiwania flousiana. The results showed that these three trace elements had significant effects on the height,basal diameter,branch number,and lateral root of 2-year old seedlings under the same fertilization.The best performance of seedling growth happened in the treatment of A₁B₂C₂,where 0.03% MnSO₄ and 0.03% H₃BO₃ were sprayed without ZnSO₄.The growth indices of 2-year old seedlings reached average height of 32.5 cm,basal diameter of 3.91 mm,12.9 branches,and 7.3 lateral roots.
