In order to implement precise fertilization, reduce application amount of nitrogen, phosphorus, potassium, and increase the nutrient absorption and utilization rate of grapevines as well as the quality and yield of grape, two grape varieties, "Golden Finger" and "Longyan", are used as test subjects, a comparative experiment is carried out to explore the effect of grape balanced nutrition fertilizer. The experimental results show that the single fruit weight, panicle weight and yield of grape can be improved to varying degrees under the condition of greatly reducing the application amount of nitrogen, phosphorus and potassium. The contents of soluble solids, soluble total sugars, organic acids, VC, total phenols, flavonoids, amino acids, etc. of grape fruits also increase to varying degrees. Grape balanced nutrition fertilizer not only achieves the effect of reducing fertilizer and increasing efficiency, but also can greatly improve grape quality.
