The introduction of the nutrient controller

The nutrient controller is an agricultural instrument. As we all know, plant nitrogen, chlorophyll and water content are important nutritional and physiological parameters for plant growth and important parameters reflecting plant vital signs. It is also an important basis for fertilization and irrigation of plants. However, in the research of agriculture and forestry at home and abroad, the only instrument(nutrient controller) that can be used to detect chlorophyll is chlorophyll meter. However, the SPAD value measured by chlorophyll meter is only a comparison value of reference basis, and there is only a correlation with chlorophyll content. Only the SPAD value can be used to roughly infer the level of plant nitrogen content. In this case, it can quickly and nondestructive test three kinds of plant nutrition and growth information in the field. It can be widely used in scientific research institutions and universities related to agriculture and forestry to study plant physiological indexes and guide agricultural production. Because of its small and exquisite, easy to carry, fast measurement and real-time display of data, it is loved by university teachers and researchers.
