摘　　要：以长白落叶松S1-1苗木为对象,利用正交试验方法研究氮、磷、钾肥对苗木生长量和叶绿素含量的影响,结果表明:影响苗木生长的各肥料因子表现为尿素>过磷酸钙≥硫酸钾,其中,尿素对苗高、地径及叶绿素含量的影响差异显著,为影响苗木各项指标的主导因子;培育换床苗的最佳施肥量为尿素55 g·m-2、过磷酸钙200 g·m2或150 g·m-2、硫酸钾60 g·m-2或20 g·m-2。Larix olgensis Henry S1-1 seedling was taken as objects to research the effects of nitrogenous , phosphatic and potash fertilizer to seedling growth and chlorophyll content by using orthogonal experimental method , results indicated that the effects of influence factors was urea 〉 superphosphate ≥potassium sulfate , including that the influence of urea presen-ted significant difference to seedling height , ground diameter and chlorophyll content , which was the dominant factor that affected seeding indicators .The best fertilizing amount of transplanting seedling was urea 55 g· m^-2 , superphosphate 200 g· m^-2 or 150 g· m^-2 , potassium sulfate 60 g· m^-2 or 20 g· m^-2 .
