近年来,运用叶分析技术测定柑桔植株的营养状况,并以此指导果园施肥,国内外已有大量报道。但是,Childers认为,在进行植株营养诊断时,除叶片分析外,还需要对果实进行分析,因为有时叶片中的元素含量常说明不了果树真正需要或不需要哪一种营养元素。Gallasch等也报道了采用果汁分析测定柑桔需肥状况的可行性。本试验对柑桔果皮的氮、磷、钾、钙、镁和有效硼等
In recent years, the use of leaf analysis technology to determine the nutritional status of citrus plants, and as a guide orchard fertilization, a large number of reports at home and abroad. However, Childers believes that in the diagnosis of plant nutrition, in addition to the leaf analysis, the fruit needs to be analyzed because sometimes the content of the elements in the leaf often can not explain what kind of nutrients are really needed by the fruit tree or not. Gallasch et al. Also reported on the feasibility of using fruit juice analysis to determine the status of fertilizer use in citrus. The test of citrus peel nitrogen, phosphorus, potassium, calcium, magnesium and available boron
