摘　　要：以进入结实盛期的北五味子果林母树为试验材料,以氮肥、磷肥和钾肥为处理因素,每种处理因素设置3个试验水平,连续3个年度进行施肥试验。结果表明:施肥对果实增产效果显著,3种肥料之间的交互作用效果亦显著,其中以施用氮肥150 kg·hm-2、磷肥150 kg·hm-2、钾肥90 kg·hm-2的施肥量配比增产效果最佳,果实比对照增产46.3%。A fertilization study of Schisandra chinensis was conducted for three consecutive years.It was an experiment of three treatments with three levels.The treatments were nitrogen,phosphorus and potassium,respectively.The results showed that the effect of fertilization on fruit yield was significant,and interactions among treatments were also signifcant.The optimal treatment was a combination of 150 kg·hm-2 nitrogenous fertilizer,150 kg·hm-2 phosphorus fertilizer and 90 kg·hm-2 potassium fertilizer,which increased 46.3% yield more than the control.
