苹果叶分析是目前果树营养诊断中比较成熟的有效方法。近年来,随着科学技术的发展,果树营养诊断的分析工作已从常规的化学分析进入仪器分析阶段,分析速度和精度都大大提高了。因而,对叶样粉碎的速度也必须相应地跟上。在果树营养诊断研究中,需要同时分析10种以上元素的含量,以便根据养分平衡学说来分析判断各元素之间的关系。对于微量元素的分析,叶样处 Apple leaf analysis is the fruit tree nutrition diagnosis more mature and effective method. In recent years, with the development of science and technology, the analysis of nutritional diagnosis of fruit trees has entered the stage of instrumental analysis from the conventional chemical analysis, and the speed and precision of analysis have been greatly increased. Thus, the rate of comminution of the leaves must also be kept up accordingly. In the study of nutrition diagnosis of fruit trees, it is necessary to analyze the contents of more than 10 elements at the same time so as to analyze and judge the relationship among elements according to the theory of nutrient balance. For trace element analysis, leaf-like place
