The purpose and significance of the plant nutrition tester
What is the purpose and significance of the plant nutrition tester? This also needs to be said from the understanding of this product, plant nutrition tester, also known as plant nutrient tester, is 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 of plant growth, and are important parameters reflecting plant vital signs. It is also an important basis for plant fertilization and irrigation. Plant nitrogen content, chlorophyll and leaf temperature are important nutrient and physiological parameters of plant growth, and are important parameters reflecting plant vital signs. It is also an important basis for plant fertilization and irrigation. The nitrogen content is generally directly reflected in the health of the crop, the growth state, understanding the true nitro requirement of the plant and the lack of soil nitro or the excessive application of nitrogen fertilizer, widely used in nitrogen fertilizer management, herbicide application, Leaf senescence, environmental stress and other research, chlorophyll measuring instrument has great significance in the agricultural planting process. The chlorophyll content is determined by the SPAD value, which is the ratio of the number of leaves transmitted by the leaves at two wavelengths of 650 nm and 940 nm. The relative number of chlorophyll in the leaves is determined (the transmission coefficient in the two wavelength ranges to determine the current blade). The relative amount of chlorophyll), SPAD value is directly proportional to chlorophyll, so the SPAD value often indirectly represents the chlorophyll value, so that the health status and growth state of the plant can be evaluated. Therefore, in agriculture, the chlorophyll meter is often used to carry out the plant The chlorophyll content is tested to guide the application of nitrogen fertilizer. Therefore, the chlorophyll meter is used in the agricultural planting process to guide the nitrogen content, and in many plants, the plant resistance is judged. Leaf temperature is often used to indicate the body temperature of plants. All chemical reactions in plant leaves are affected by leaf temperature and are often used in the analysis of plant physiological activities. The difference between leaf temperature and temperature can indicate the water shortage of plants or the degree of drought. Because when the water supply is sufficient, the plant transpiration is normal, the transpiration heat can reduce the plant body temperature, then the leaf temperature is lower than the temperature; otherwise, when the drought occurs, the plant body temperature rises, which can be higher than the current temperature. However, the only instruments that can be used for rapid nitrogen detection at home and abroad are the chlorophyll meter, which tests the SPAD value, and only estimates the nitrogen content of the plant according to the SPAD value. The plant nutrition tester can quickly and non-destructively test the plant's chlorophyll, leaf nitrogen content, leaf temperature three nutrients and physiological growth information, which is of great significance for agricultural research and production. 24% Flavonoids Ginkgo Biloba Extract is a kind of Ginkgo Biloba Leaf Extract, which is the Key Product of our company.
