摘　　要：为提高巴西人参在林下的产量及其品质,明确不同肥料处理对其早期生长发育的影响,采用磷肥、钾肥和复合肥对林下巴西人参幼苗进行施肥处理,观察比较了不同处理对巴西人参早期生长发育影响的差异,为林下巴西人参的合理施肥提供理论依据。结果表明:3种肥料处理可不同程度影响巴西人参早期的生长发育,不同施肥处理之间除对巴西人参幼苗地径影响不显著之外,对株高、分枝数量、叶长、叶宽和生物量等生长指标的影响存在显著差异;综合来看,实验中复合肥对巴西人参幼苗生长发育促进效果最佳,钾肥次之,磷肥最差。In order to improve the yield and quality of Pfaffia paniculata under the forest and clarify the effects of different fertilizer treatments on its early growth and development,phosphate fertilizer,potassium fertilizer and compound fertilizer were used to fertilize Pfaffia paniculata under the forest seedlings,and the differences in the effects of different treatments on the early growth and development of Pfaffia paniculata were observed and compared,so as to provide a theoretical basis for the rational fertilization of Pfaffia paniculata under the forest.The results showed that the three fertilizer treatments could affect the early growth and development of Pfaffia paniculata to different degrees,and different fertilization treatments have obvious differences in plant height,branch number,leaf length,leaf width,biomass and other growth indicators.While there are no obvious impact on the ground diameter of Pfaffia paniculata seedlings.Overall,in this experiment,compound fertilizer had the best effect on the growth and development of Pfaffia paniculata seedlings,followed by potassium fertilizer and the worst phosphate fertilizer.
