为研究临安山核桃林土壤理化性状的变化，在临安山核桃林主产区采集263个土壤样品为实验材料，对山核桃林土壤进行分析。结果表明，山核桃林土壤随着农户化肥施用量的增加，土壤有机质、速效养分含量不同程度的提高，但土壤pH迅速下降；而有效硼、有效锌含量较低。通过分析，更进一步表明，由于长期施用化学氮肥，山核桃树生长和产果所需的养分与土壤供给的养分不平衡。为此，改为施用氮、磷、钾复合肥或山核桃专用肥，特别增施硼肥，对山核桃主产区土壤肥力和山核桃林吸收养分平衡至关重要。

263 soil samples were gathered from the main Chinese hickory production area of Linan to analyze a change in soil physical and chemical properties. The results show that with the increasing application amount of chemical fertilizer in the main Chinese hickory production area of Linan, the contents of organic matter and some available macro-nutrients, to different extent, increased in the soil, accompanied by a sharp fall in soil pH value and the low contents of available boron and zinc in the soil. Thus, it’s recommended that the compound fertilizer including N, P and K nutrients or Chinese hickory specific fertilizer should be applied, along with the addition of boron fertilizer due to the long-term more application of chemical nitrogen fertilizer, which may lead to an unbalance in nutrients between supplied by the soil and needed by the growth and fruition of Chinese hickory.
