摘　　要：为探究不同施肥方式对混交造林的影响,以江西省赣州市南康区大山脑国有林场作为杉木木荷混交林试验地,进行梯度施肥实验,分别设置复合肥梯度为100、200、300 g/株和不施肥对照(CK)。结果表明:各个梯度施肥方式均显著促进了杉木和木荷高度和地径的增长,造林8个月后,100 g/株施肥方式杉木高度最高为47.1 cm,地径最大为9.1 mm,相对对照(CK)分别增长33.4%、18.2%;200 g/株施肥方式木荷高度最高为99.6 cm,地径最大为13.1 mm,相对对照(CK)分别增长28.8%、21.3%。从培育成本考虑,以施肥量100 g/株为最佳。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 fertilization experiments were conducted,with compound fertilizer gradients of 100,200,300 g/plant and no fertilization 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 increase of 33.4%and 18.2%compared to the control(CK);The maximum total height of the 200 g/plant fertilization 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.
