摘　　要：笔者采用正交试验设计方法,单施尿素以及尿素、过磷酸钙、氯化钾不同组合配比施肥对黄连木幼苗进行处理,通过对苗高、干重、茎根比三个形态指标分析。试验结果表明,黄连木幼苗单施氮肥,施肥量以株施0.5～1g/kg为宜;黄连木幼苗应多施氮肥;对黄连木幼苗综合施肥,施肥比例以N∶P2O5∶K2O=12～6∶1∶2,苗木生长质量较好。Based on orthogonal experiment, the paper studies on different proportion of nitrogen, phosphorus and potash fertilizer and only nitrogenous fertilizer on seedling growth of the Pistacia chinensis Bunge. Through analysis of the height, dry weight and shoot to root ratio of the seedling, the experiment has proved that the suitable amount of fertilization for only nitrogenous fertilizer is 0.5~1g/kg per seedling. For different levels of nitrogen, phosphorus and potash fertilizer, the applicable proportion of N∶P_(2)O_(5)∶K_(2)O is equal to 12~6∶1∶2.
