The chlorophyll meter and the chlorophyll fluorescence meter are very similar in name, so many people will confuse the two instruments, but in fact, they are completely different instruments, whether for research purposes, measurement methods, methods of use, and objects of use. There are big differences on it. So let's briefly introduce the differences between the chlorophyll meter and the chlorophyll fluorescence meter. 1. Different research purposes The chlorophyll meter is mainly used for the portable chlorophyll meter, which is mainly used to judge the nutritional status (especially the nitrogen level) in the process of plant growth, and provides a reference for the production of crop fertilization, which belongs to the field of applied research. The chlorophyll fluorometer mostly studies the mechanism of photosynthesis, such as the process and efficiency of electron transfer, the function of photosynthetic reaction center II (PSII) and reaction center I (PSI), environmental changes (drought, saline, metal pollution). The influence on electron transfer is a category of theoretical research. 2. Measurement method The measurement method used by different chlorophyll meters is to use the special absorption characteristics of chlorophyll to red light, and the amount of red light absorption is measured by photoelectric sensor. Therefore, the measurement of chlorophyll analyzer is at a certain point. Instantaneous measurement. The chlorophyll fluorescence instrument utilizes the fluorescence phenomenon unique to chlorophyll, and uses a sensor with extremely high sensitivity and reaction speed, supplemented by a photoelectric pulse design to capture fluorescence data at various times during electron transfer. Fluorescence measurement is a process measurement. 3. Different methods of use The chlorophyll meter is used to measure the chlorophyll content of plant leaves. It is necessary to make time to make correction curves for different samples. When measured using a chlorophyll fluorometer, the leaves need to be dark treated for a longer period of time. Therefore, there are obvious differences in the method of use. 4, the use of different objects, chlorophyll meter and chlorophyll fluorescence instrument are also used in different objects, such as chlorophyll meter used in agricultural extension stations, agricultural technology station (station) production technical guidance, and chlorophyll fluorescence instrument is mostly used in scientific research units, Research work in universities and colleges. The above is the difference between the chlorophyll meter and the chlorophyll fluorescence meter. Through the above explanation, I believe that everyone will have a clearer distinction between the two instruments, and it will be clearer in the process of selection in the future.
