L.K.Jackson指出:“叶片分析是测定柑桔果树营养状态的最好标准。佛罗里达州在过去二十年中已广泛应用叶片分析于柑桔营养与肥力的研究,但是个别的生产者未注意采用。“叶片分析的好处是从某一施肥措施来确定果树多年的营养状态趋势。这样的趋势靠每年的分析可以最好地测定出来。叶片分析对解决病态抽梢的营养问题也有益,特别 LKJackson points out: “Leaf analysis is the best standard for determining the nutritional status of citrus fruit trees. Florida has extensively studied the use of leaf analysis in citrus nutrition and fertility for the past two decades, but individual producers are not aware of it. ”The benefit of leaf analysis is the determination of the nutritional status of fruit trees from years of fertilization. This trend is best measured by annual analysis. Leaf analysis is also beneficial for addressing the nutritional problems of diseased shoots, especially
