葡萄叶片氮磷钾营养状况直接影响着葡萄果实的品质和产量．本试验通过叶片分析探讨葡萄的氮磷钾营养特点，为南方葡萄优质高产提供合理施肥的依据．试验材料与方法试验布置包括盆栽与田间试验两部分，盆栽试验品种为巨峰，枝条扦插的小苗移栽到玻璃网室培养，试验设置13个处理 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
