Commercial cultivation of blueberry has rapidly expanded in China in recent years. However, suboptimal fertilization results in poor growth and management practices in blueberry orchards. The present study studied fertilization of southern highbush blueberry in southwest of China. We evaluated the effects of inorganic nitrogen, phosphorus, and potassium fertilizers at different doses. Plant vegetative growth, leaf photosynthesis parameters, fruit quality and soil nutrient contents were analyzed. Application of ammonium sulfate enhanced fruit weight, sweetness, and nutrient content, including vitamin C and anthocyanin contents. Comparison of P and K fertilizer treatments revealed that 30 g P/plant in combination with 30 g K/plant conferred superior plant growth and improved fruit sweetness and nutrient content. Using ammonium sulfate as the N source and monopotassium phosphate as the P and K source contributed to maintenance of soil acidity
