In order to explore the effects of different fertilization methods on mixed afforestation,this study used Dashannao State-Owned Forest Farm in Nankang District,Ganzhou City,Jiangxi Province as an experimental site for mixed forests of Cunninghamia lanceolata(Lamb.)Hook and Schima superba Gardn.et Champ.Gradient ferti-lization experiments were conducted,with compound fertilizer gradients of 100,200,300 g/plant and no fertiliza-tion control(CK)set.The results showed that all gradient fertilization methods significantly promoted the growth of the total height and ground diameter of Cunninghamia lanceolata(Lamb.)Hook and Schima superba Gardn.et Champ.After 8 months of afforestation,the highest total height and ground diameter of Cunninghamia lanceolata(Lamb.)Hook under the 100 g/plant fertilization method were 47.1 cm and 9.1 mm,respectively,with a relative in-crease of 33.4％and 18.2％compared to the control(CK);The maximum total height of the 200 g/plant fertiliza-tion method is 99.6 cm.and the maximum ground diameter is 13.1 mm,with a relative increase of 28.8％and 21.3％compared to the control(CK),respectively.Considering the cultivation cost,the optimal fertilization rate is 100 g/plant.
