Abstract
多年來作農業研究的人常有一種感覺，就是用少數樣品作精細的分析不如採取多數的樣品作準確度較差的分析。這種要求常使我們覺得需要將過去的分析方法加以修改而使它更適台於我們的目的。一般將分析法微量化可減少操作上的一些負擔，但如能將分析缺的部分操作簡化，在多數樣品分析工作上的幫助也同樣值得重視。本研究室多年來從事於植物體的分析工作，經屢次改良漸近乎理想而成一分析系統。現將彙編成文以供大家參考，並有不足之處請大家指教。
The paper describes the mothod for the determination of nitrogh, phosphorus and potassium in plant tissue which is adapted by Plant Nutrition Laboratory (TARI) in its routine analysis The method is suitable for handling large samples and has some advantages over other conventional methods so far as simplicity and minimum of cost are concerned. In principle, the method uses sulfuric perchloric acid digestion and subsequent determination of nitrogen phosphorus and potassium by Conway’s micro-diffusion acid titration, molybdate blue spectrophotometry and flamephotometry, respectively, Precautions in using this method are carefully described and explanations given to make the experimenter understand the basic principles involved.
