What is the purpose and significance of the plant nutrient rapid analyzer? This also needs to start from understanding this product, plant nutrient fast tester, also known as plant nutrient analyzer, instrument model TYS-3N. The instrument is independently developed by Top Instrument and widely used in the measurement of nutrients in agricultural and forestry plants. Plant nitrogen content, chlorophyll, and leaf temperature are important nutrient and physiological parameters for plant growth and are important parameters reflecting the vital signs of plants. It is also an important basis for plant fertilization and irrigation.
Plant nitrogen content, chlorophyll, and leaf temperature are important nutrient and physiological parameters for plant growth and are important parameters reflecting the vital signs of plants. It is also an important basis for plant fertilization and irrigation.
The nitrogen content directly responds to the crop's health, growth status, understanding of the plant's actual nitro requirement and the lack of soil nitro, or excessive application of nitrogen fertilizer. It is widely used in nitrogen fertilizer management, herbicide application, Leaf senescence, environmental stress and other studies, chlorophyll measurement instrument in the process of agricultural cultivation has great significance.
The chlorophyll content was determined as the SPAD value, which was calculated by comparing the ratio of the number of light transmitted by the blade at two wavelengths of 650 nm and 940 nm to determine the relative amount of chlorophyll present in the leaf (the transmittance coefficient in the two wavelength ranges was used to determine the leaf current The relative amount of chlorophyll), SPAD value is directly proportional to chlorophyll, so SPAD values ​​often indirectly represent chlorophyll values, which can be used to assess plant health and growth status. In agriculture, chlorophyll meter is often used to perform Chlorophyll content was measured to guide the amount of nitrogen fertilizer applied. Therefore, the chlorophyll meter was used to conduct nitrogen fertilization in the agricultural planting process. At the same time, in many plants, the resistance of plants was judged.
Leaf temperature is commonly used to indicate the temperature condition of a plant. All chemical reactions in plant leaves are affected by leaf temperature and are often used in the analysis of plant physiological activity. The difference between leaf temperature and temperature can indicate the lack of water or drought in the plant. Because when the water supply is sufficient, the plant transpiration is normal, and the transpiration and heat consumption can reduce the temperature of the plant. At this time, the leaf temperature is lower than the temperature. On the contrary, when the drought occurs, the plant temperature rises and can be higher than the temperature at that time.
However, the instruments that can be used to rapidly detect nitrogen at home and abroad are only chlorophyll meters. The SPAD value is tested. The plant nitrogen content can only be estimated based on the SPAD value. Our company broke through tradition and cooperated with Zhejiang University to develop the first plant nutrient fast measuring instrument based on near infrared spectroscopy non-destructive testing method and data mining technology. The rapid non-destructive testing of the chlorophyll, leaf nitrogen content, and leaf temperature of the three nutrients and physiological growth information in the field is of great significance for agricultural research and production.

Plant nutrient rapid analyzer product description:
Plant nutrient rapid tester features:
1. The three parameters (chlorophyll, nitrogen, leaf temperature) can be displayed at the same time and can be saved, which facilitates the mapping of plant nutrients and other information distribution graphics, and provides basis for accurate fertilization of plants.
2. Rapid and non-destructive testing of plants in vivo, without damaging the crops and without affecting plant growth.
3. Multi-parameter fast one-time measurement: The chlorophyll, nitrogen, and leaf temperature of the plant were measured at one time.
4. Acquisition of test point positioning information: Through the built-in GPS module in the instrument, it is received by the serial port interrupt mode through the NAME-83 protocol, and the received data is decoded into latitude, longitude, speed, and time (clock and calendar, year and month Time, minutes, seconds, and direction angles are displayed and stored simultaneously. The time can be manually set. (Multifunction model is equipped with this function)
