摘　　要：本文评述了葡萄叶分析营养诊断技术及其在葡萄施肥中的具体应用。要成功地运用叶分析技术进行葡萄营养诊断,就必须建立统一的取样、制样、标准分析方法及各品种叶矿质元素含量的标准值。解释叶分析结果的主要方法有临界值法、适宜值法和比值法。叶分析诊断技术主要应用在确定葡萄施肥种类、施肥时期、施用量及测定葡萄植株对肥料反应的研究等方面。Leaf analysis technique and its application in grape fertilization were summarized in this paper. To diagnose thenutritional status of grape with leaf analysis technique successfully, the uniform method of leaf sampling, making sample, standardanalysis method and standard values of mineral elements content in different kinds of grape leaves should be founded. Three majormethods of data interpretation are critical values, sufficiency ranges and ratios. The technique is mainly used to confirm the typesand periods of fertilization, fertilization rates and the response of the grape to fertilizers.
