Mineral nutrition is the basis for plant growth and development, yield formation and quality improvement. Mineral nutrient analysis and diagnostic techniques are prerequisites for accurate fertilization. Through the nutritional diagnosis of plants to track the deficiency of plant nutrition, to understand the key period of fertilizer needs, so as to guide people in timely and appropriate amounts of fertilizer, to meet their optimal growth needs, in order to achieve the production of fertilization on-demand, and ultimately achieve The purpose of environmental protection economy. Many countries have widely used it as an important means for the modernization of agriculture (forestry) production science and technology in a variety of crops and trees, and have achieved good results. The plant nutrient diagnosis instrument can effectively determine the nutrition of plants and provide scientific basis for the growth and development of crops.
In recent years, the use of electronic computers to process complex diagnostic data and various parameters affecting plant production to formulate fertilization schemes has opened up a broad path for the accuracy and prediction of diagnostics. The diagnosis of plant nutrition in developed countries has reached the stage where commodity production is widely used. They have a central functional agency that specializes in the diagnosis of plant nutrition. Since the 1960s, with the improvement of analytical instruments, the diagnostic methods and applications of plant nutrition have made great progress. Many methods have been proposed in succession. This brings flexibility to the choice of applying these methods in our production, but it also brings arduousness. The diagnosis method of plant nutrition diagnosis instrument directly affects the accuracy and practicality of the diagnosis result. Therefore, how to choose the correct, reasonable, economical and practical diagnosis method has become an issue that people are increasingly concerned about.
The leaf is the main organ for nutritional diagnosis. The changes in nutrient supply are more obvious on the leaves. Leaf analysis is the most quantitative method that can easily be standardized in nutrition diagnosis. However, sometimes it is difficult to explain the problem only by the total content of elements, especially calcium, iron, zinc, manganese and boron. Such elements that are particularly prone to exhibit physiological inactivation in fruits and leaves often do not have a low total amount, but are due to the loss of transport or metabolic activity leading to the occurrence of deficiency symptoms. Therefore, in addition to leaf analysis, analysis of other plant organs may also be used according to different diagnostic purposes, or relative to full-quantity analysis/component 0 analysis, as well as histochemical, biochemical and physiological measurements.
Since malnutrition generally occurs in some typical changes in plant physiology and biochemistry and tissues, modern biotechnology and experimental methods can be used to determine the nutritional balance of plants through physio-biochemical and tissue morphology analysis. For example, potassium, phosphorus, zinc, and other elemental nutrition levels can be tested using the morphology of vegetable leaves. Anatomic and histochemical methods can also be used to test the nutritional balance of plant copper.
In general, the plant nutrient diagnosis instrument has its own advantages and disadvantages in its nutrient measurement and various plant nutrient diagnosis methods. In production, it can only be used in combination with actual conditions to obtain correct nutritional diagnosis, improve diagnostic efficiency, and reduce diagnostic costs.
