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 ” apple as test material, soil nutrient status and fruit quality of four dwarfed and dense apple orchards in Tuanjie Subdistrict Office in Xishan District of Kunming were investigated, measured and analyzed. The results showed that the average soil pH value of four dwarf and close planting apple orchards was 5.99. The content of soil organic matter, available nitrogen, available phosphorus and available potassium was low, and there was a big difference in the application level of various fertilizers between orchards. There was a positive correlation between soil organic matter and soil nutrients, and the pH value was negatively correlated with soil nutrients. There was also a correlation between soil nutrients and fruit quality. Among them, the correlation between single fruit quality and soil organic matter, total nitrogen, total phosphorus, total boron, Available nitrogen, available phosphorus, available potassium were positively correlated with soil pH value was a significant negative correlation, soluble solids and pH value, organic matter, total nitrogen, available potassium was positively correlated.
