试验研究了胶东苹果园土壤中有效养分对pH值的影响。结果表明，胶东苹果园土壤普遍显酸性，pH值小于5．5的不适宜苹果树生长的土壤占调查总数的28．53％。土壤pH 值与有效态养分含量之间关系密切，土壤pH值随土壤有机质、碱解氮、速效磷和速效钾含量的增加均呈现降低趋势，其中随土壤碱解氮含量的增加下降趋势明显。

The effective nutrients in apple orchard soil of Jiaodong region were determined and theireffects on pH value of soil were studied.The results showed that the soil of Jiaodong apple orchards was gener -ally acidic; the soil with pH value less than 5.5 and not suitable for apple growth was accounted for 28.53%of total.Soil pH value had close relation with effective nutrients , which decreased with the content increase oforganic matter, alkaline hydrolytic nitrogen, available phosphorus and potassium, especially the alkaline hydrolyticnitrogen content.
