N, P and K nutritional status of grape leaves directly affect the quality and yield of grape fruit. In this experiment, we discussed the characteristics of nitrogen, phosphorus and potassium nutrition of grape by leaf analysis and provided the basis for rational fertilization of high quality and high yield of southern grape. Test materials and methods The experimental arrangement includes two parts: potted plants and field experiments. The varieties of potted plants were giant peaks. The seedlings of branches and shoots were transplanted into glass net room for culture. Thirteen treatments
