摘要：在开放体系中用1 mol L ~（-1）HNO_3煮沸提取K和Mg用于预测植物对K和Mg的吸收是一种重复性低的方法。本研究的目的是比较不同的酸法相对于氢氟酸提取钾和镁的提取能力。另一个目的是开发一种化学提取方法，使用封闭系统（微波）的非交换和结构形式的这些营养素，以[...]
ABSTRACT: Extraction of K and Mg with boiling 1 mol L-1 HNO3 in an open system for predicting K and Mg uptake by plants is a method of low reproducibility. The aim of this study was to compare the extraction capacity of different acid methods relative to hydrofluoric acid extraction for K and Mg. A further objective was to develop a chemical extraction method using a closed system (microwave) for nonexchangeable and structural forms of these nutrients in order to [...]
