摘　　要：采用基质与肥料进行蓝莓栽培试验,研究氮磷钾对蓝莓生长发育性状的影响,以研发出更加节肥、高效的基质营养配方。通径分析表明,基质磷(通径系数0.344)、肥料磷(通径系数0.529)与成活率呈极显著正的通径关系。回归分析表明,影响单株叶片数的最佳施氮量为4.0871 g,最佳施磷量为4.5587 g,最佳施钾量为5.0499 g。The effects of nitrogen, phosphorus and potassium on the growth and development traits of blueberry were studied by substrate and fertilizer, in order to develop a more fertilizer-saving and efficient matrix nutrition formula. Path analysis showed that there was a significant positive path relationship between matrix phosphorus, fertilizer phosphorus and survival rate. Regression analysis showed that the optimum nitrogen application rate, phosphorus application rate and potassium application rate were 4.0871 g, 4.5587 g and 5.0499 g, respectively.
