In recent years, plant nutrition science has been continuously developed, and only field research on plant nutrition can hardly reveal the nature of plant nutrition. It is necessary to further reveal the essence of plant nutrition through various simulation experiments under artificially controlled simulation conditions. The plant nutrient analyzer plays an important role in the study of plant nutrition.
Modern plant nutrient simulation tests are automated devices controlled by electronic computers and automated research of plant nutrient analyzers, and are characterized by high management efficiency, accuracy, and high precision. And their relationship with the enzyme reaction, or the change of the atom valence, the transfer of electrons, or as a bridge between the substrate and the enzyme, changes the molecular structure of the enzyme-matrix complex, most of these studies use higher concentrations of inorganic ions, In a laboratory test tube, an ex vivo tissue experiment was performed. However, in the whole plant tissue cells, especially on the plasma membrane where the enzyme reaction is carried out, the ion concentration is not so high. It is doubtful whether the requirement for activating the enzyme can be met. Therefore, in the late 20 years, research methods in the field of plant nutrition have shifted from isolated tissues to whole plants of the plant nutrient analyzer.
Plant nutrient analyzer has radionuclide tracer technology, stable nuclear tracer technology, activation analysis technology and nuclear radiation technology, especially the application of radionuclide tracer technology, promotes the study of ion absorption and transport mechanism. At the same time, the enzymatic kinetic theory and the carrier concept were used to clarify the selectivity of ion absorption.
