摘　　要：本文采用正交设计对红松播种苗进行了施肥效应研究,测定了不同施肥组合条件下苗木的形态指标。结果表明:影响苗木生长的各肥料因子的顺序依次为C(追施尿素)、A(施基肥)、B(追施二铵),促进苗木生长的较佳施肥组合为A3(4)B1C3,即基肥用量为有机肥7 500 g/m2+二铵7g/m2或有机肥7 500 g/m2+二铵7 g/m2+硫酸钾12 g/m2;追肥二铵用量为0;追肥尿素的用量为30 g/m2。The effect of fertilization on growth of Pinus koraiensis seedlings was researched in this article. The results were as follows： The effect sequence of different fertilizer factor in proper order was C （additional fertilizer of CO （NH22）, A （basic application）and B（additional fertilizer of （NH4）2 HPO4 ）. The fertilizing regime A3（4）B1C3 had better effect on growth of seedlings. The regime was composed of basic fertilizer （organic fertilizer 7 500 g/m^2 ＋ （NH4 ）： HPO4 7 g/m^2 or organic fertilizer 7 500 g/m^2 ＋ （NH4 ）2 HPO4 7 g/m^2 ＋ K2SO4 12 g/m^2 ） and additional fertilizer of CO（NH2）2 with application rates of 30 g/m^2 .
