In order to explore the effect of different formula fertilizations on growth of theTaiwania flousiana planted young forest, fertilization experiment in Gaoloushan plantation TianE county of Northwest Guangxi. The author introduced three formula fertilizations, namely A was 25.5% of N, 5.3% of P, 6.0% of K; 0.2% of copper sulphate, 0.5% of zinc sulfate, 1% of borax ; B was 20.9% of N, 6.0% of P, 9.0% of K; 0.2% of copper sulphate, 0.5% of zinc sulfate, 1% of borax and C was N,P,K compound fertilizer,the total amount of ≥48%.The results showed that the average diameter of 4 a of youngTaiwania flousiana were 7.12~8.33cm, the average tree height were 2.86~3.59m while the average crown were 1.92~2.39m2. The overall, the effect of formula B was more significantly.
