摘要： 为研究‘泽州红’山楂古树生长情况与土壤化学特性间的关系，通过野外采集土样、实验室测定和数据处理，对山西晋城百年以上42棵山楂古树生境的土壤化学特性进行了分析。结果表明：42棵山楂古树生境土壤大部分为中性非盐渍土壤，少数为碱性或酸性土；土壤有机质及速效养分含量均存在一定的差异；适宜山楂古树生长的土壤pH、全盐量、有机质含量、有效氮含量和有效钾含量5项指标的正常标准分别为pH 6.92~7.29，0.05%~0.06%，20.11~28.05 g/kg，40.81~50.99 mg/kg，117.85~147.06 mg/kg。有效磷含量由于不符合正态分布，不能进行概率分级，而未能得出标准值。说明该区山楂古树生境土壤状况亟待改善。

Abstract: In order to research the relationship between growth situation and soil chemical characteristics of ancient hawthorn tree ‘Zezhouhong’, the author analyzed soil chemical characteristics of 42 ancient trees of hundreds years old in Shanxi Jincheng through collecting soil sample, laboratory test and data treatment. The results showed that most soil samples of 42 ancient hawthorn trees were neutral saline and a few were alkaline or acid. There were some differences in soil organic matter and available nutrient content. The normal standards of pH value, salt content, organic matter, available nitrogen and available potassium for growth were pH 6.92-7.29, 0.05%-0.06%, 20.11-28.05 g/kg, 40.81-50.99 mg/kg, and 117.85-147.06 mg/kg, respectively. The standard of available phosphorus was not given because the content did not conform to normal distribution law and could not be graded. This means that the soil condition of the ancient trees needed to be improved urgently.
