We know that the more plant information we acquire, the more we understand it and the more comprehensive it is, the more refined it will be in fertilizing and irrigating. In order to increase the understanding of plants, modern plants often use chlorophyll detectors and other plant physiological testing instruments to conduct research on plants. This not only increases the efficiency of work but also saves a lot of time, while the use of instruments such as chlorophyll detectors. It also promoted the modernization of agriculture.
Plant research work is all-sided. Chlorophyll detectors are just one of them. Others include root analyzers and leaf area analyzers. Chlorophyll detector is mainly used to detect the chlorophyll content of plants, and then determine the nitrogen content of plants, and guide the application of nitrogen fertilizer. It is a very important test instrument used in the process of promotion of precision agriculture. Here's how to compare the chlorophyll detector with other methods for determining the chlorophyll content of a plant. What are the advantages of using a chlorophyll detector? Is it worth the large-scale promotion and application?
There are mainly three ways to determine the nitrogen content of plants, and the chlorophyll detector method is one of them. It can directly measure the SPAD value in the leaves and then calculate the nitrogen content according to the critical value, so it is a direct measurement method. The method of determination has more or less certain drawbacks, such as the use of a soil tester to determine the content of nitrogen in the soil, and then indirectly to determine the plant chlorophyll content, which is an indirect method; or the use of visually measuring the color of the leaf Change to judge, this is a kind of past experience judgment method, often used in the past agricultural production process, but this method is not accurate because it is not quantitative analysis.
By comparison, it can be seen that the use of chlorophyll detector to determine the chlorophyll content of plants is an ideal and simple and convenient way to quickly and accurately monitor the nitrogen status of crops in the field, determine the absence of nitrogen, and provide timely The information needed for topdressing can therefore be widely used and promoted in modern agriculture.
