摘　　要：以"金世纪"苹果为试材,对昆明市西山区团结街道办事处4个矮化密植苹果园的土壤养分状况、果实品质进行了调查、测定和分析。结果表明:4个矮化密植苹果园的土壤pH值平均为5.99;土壤有机质、碱解氮、速效磷、速效钾含量偏低,且果园之间各肥料的施用水平存在较大差异。土壤有机质与土壤各养分间均呈正相关,pH值与土壤各养分间呈负相关;不同土壤养分与果实品质也存在着相关性,其中单果质量与土壤有机质、全氮、全磷、全硼、碱解氮、速效磷、速效钾均呈正相关,与土壤pH值呈极显著负相关,可溶性固形物与pH值、有机质、全氮、速效钾呈正相关。Taking ＂Golden Century＂ as test material,the soil nutrients and fruit qualities of four short-stalk close planting apple orchards in Xishan Tuanjie Subdistrict,Kunming city were investigated and analyzed. The results showed that the average values of soil pH value were 5.99 in these four short-stalk close planting apple orchards. The contents of soil organic matter （OM）,alkaline nilrogen （N）,available phosphorus （P） and available potassium （K） were very low. In addition,there was a big difference between the fertilizer application levels of these four short-stalk close planting apple orchards. Furthermore, soil OM had positive correlation with all soil mineral elements, while soil pH value had negative correlation with most of soil mineral elements. The soil nutrients,pH value and fruit quality existed different sizes of correlation coefficients ;fruit mass had positive correlation with soil OM, total N, total brachium（B）, alkaline N, available P and available K, and significant negative correlation with soil pH value; soluble solids content had positive correlation with soil pH value,soil OM,total N and available K.
