Abstract: The experiment of fertilizer and afforestation density of young plantation Fokienia hodginsii was carried in 1998.The results showed that Fokienia hodginsii was sensitive to fertilizer and the fertilizer effect sustained for a long time.Phosphate fertilizer should be mainly applied for Fokienia hodginsii and the ideal fertilizer amount is 200 g/tree of calcium magnesium phosphate fertilizer and the fertilizer effect would be better in combination with N fertilizer.The fertilizer formulation of urea 100 g, calcium magnesium phosphate fertilizer 200 g and potassium chloride 50 g for each tree brought an increase of 44.6% in height growth, 42.3% in diameter, 182.99% in volume of timber, and the index of fertilizer effect reached 2.93 and the economic results reached 64 631 yuan/hm².The treatment of urea 50g/tree and Ca、Mg and P 200 g/tree gained the economic effects of 57300 yuan/hm².The results also indicated that the best afforestation density was 2.0 m×1.5 m in spacing to the Fokienia hodginsii young plantation.
