果树营养诊断是研究果树营养规律及提供施肥理论指导的重要手段。数十年来,许多国家很重视果树营养研究,并致力于通过营养诊断达到果树高产、稳产、优质、低消耗,取得了不少进展。1966年,在美国营养生理学家Chapman主持下,归纳汇编了全世界始于三十年代后,以果树为主及其他植物的营养诊断标准。近二、三十年,一些柑桔主产国家,采用植株分析(以叶片分析为主),并结合施肥等方面的研究,以确定柑桔各营养元素的含量
Nutritional diagnosis of fruit trees is an important means to study the nutrition law of fruit trees and provide guidance of fertilization theory. For decades, many countries have attached great importance to fruit tree nutrition research and have made great progress in achieving high yield, stable yield, high quality and low consumption of fruit trees through nutritional diagnosis. In 1966, under the auspices of the US nutrition physiologist Chapman, the diagnostic criteria of nutrition prevailing in the world mainly fruit trees and other plants after the 1930s were compiled. Nearly two or three decades, some citrus-producing countries, the use of plant analysis (leaf-based analysis), combined with fertilization and other aspects of research to determine the content of citrus nutrients
