摘　　要：本文乃承接今年5月份调查陕西省洛川县于开春时使用高效复合肥“大力丸”春肥后营养生长效果,于膨果期进行追肥后并追踪其对果实质量的效果。本报告针对果实的重量、硬度、糖度和果形指数进一步总结,对比常规复合肥,高效肥“大力丸”增产12~15%,硬度提升20%以上,糖度提高5~7%。所有调查组别之果形指数均维持在红富士良好指数0.8以上。本报告总结“大力丸”使用量仅常规复合肥的10~15%且效果更优,符合国家减肥增效政策,针对大型果树极具推广价值。This is a follow-up research on previous study which studied vegetative performance of “Red Fuji” using high efficiency slow release fertilizer “Daliwan”. In this study, we further applied “Daliwan” during fruit enlarging period and studied its performances on fruit quality. Comparison was made with conventional compound fertilizer and the study concluded that apple weight increased 12% - 15%, fruit hardness increased 20%, and sweetness brix increased 5% - 7%. All group remained good fruit shape index above 0.8. “Daliwan” is concluded to fulfill China National policy in chemical fertilizer reduction and quality improvement. “Daliwan” is worth to promote for many fruit trees in China.
