Abstract: Based on the wide distribution of Cunninghamia lanceolata, Cunninghamia lanceolata plantation method has been popularized. This paper studied the effects of different fertilization treatments on growth and growth index of Cunninghamia lanceolata seedlings. The results showed that the effect of phosphorus fertilizer was significantly better than that of nitrogen fertilizer when only one fertilizer was applied. At the same fertilizer amount, the effect of base fertilizer plus top fertilizer was significantly better than that of all fertilizer applied at one time. This study provided experimental basis and theoretical reference for the artificial planting of Cunninghamia lanceolata seedlings.
