摘　　要：采取建立2个长期定位监测点，对临安山核桃产区的碳质黑油泥和黑油泥两种土壤类型进行肥力变化的研究。经6年时间前後比较，测试临安山核桃产区土壤养分含量动态变化结果。经LSD榆验法测定，结果表明，2种土壤类型的有机质、全氮、全磷、全钾、碱解氮、速效磷、速效钾、锌和铜养分含量分别比6年前增加，增加幅度均达到极显着水平；而硼、铁、钙含量分别比6年前下降，没有达到显着水平。通过两种土壤长期定位监测，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．对临安山核桃产区土壤肥力平衡提出相关的培肥措施。The fertility changes in carboniferous waxy black limestone soil and waxy black limestone soil were studied at two long-term fixed-location monitoring sites in the Chinese hickory production area of Lin＇an, Zhejiang. The results of soil nutrient analysis from two soils in 2002 and 2008 showed that after 6 years, the contents of soil organic matter, total N, P, K, available N, P, K and Zn and Cu increased and by means of the LSD test, there was statistically difference at P〈0.01 significance level between the comparative results of these soil nutrients analyzed respectively in 2002 and 2008, but no statistically difference was found when the comparison was made between the contents of B, Fe and Ca analyzed respectively in 2002 and 2008 even though there was the decrease trend of these soil nutrient contents after 6 years. The results of the long-term fixed-location monitoring of two soils also showed that due to the long-term application of chemical fertilizers, there was the imbalance between the demand of Chinese hickory for soil nutrients and the soil＇s capacity to supply nutrients. As a result, the technique of soil fertility improvement is proposed in the Chinese hickory production area of Lin＇an, Zhejiang.
