In physiological and ecological research, professional instruments such as chlorophyll meters can help scientific researchers make rapid determinations, help data management and analysis, and are good assistants in scientific research. The main function of chlorophyll meters is to determine the relative content of chlorophyll in plants, based on the absorption law of chlorophyll spectrum Employing two different light-emitting tubes to illuminate the leaves, and calculating the relative chlorophyll content or greenness of the leaves by measuring the intensity of the light passing through the leaves, so as to provide a reliable scientific basis for reasonable, appropriate and timely fertilization. The chlorophyll meter is widely used For scientific research and production guidance in agriculture, forestry, and plants. So what is the value unit measured by the chlorophyll meter? The unit of the chlorophyll value measured by the chlorophyll meter is SPAD. The SPAD value is a parameter that measures the relative content of a plant's chlorophyll or represents the greenness of the plant. The spad value has a specific proportional relationship with the nitrogen content. Nitrogen fertilizer is the main fertilizer for plants, so If the spad value is high, it means that the amount of nitrogen fertilizer is sufficient and no fertilization is required; if the spad value is relatively low, it means that the nitrogen fertilizer content is low and timely fertilization is required. Top Yunnong TYS-B Chlorophyll Meter is a high-precision plant chlorophyll measurement and analysis instrument, which can measure the relative content of chlorophyll and leaf surface temperature. The measurement range is: chlorophyll: 0.0-99.9SPAD, leaf surface temperature: -10-99.9℃ ; Measurement accuracy: Chlorophyll: within ±3.0 SPAD units (the SPAD value is between 0-50 at room temperature), leaf temperature: ±0.5℃; Repeatability: Chlorophyll: within ±0.3 SPAD units (the SPAD value is between 0-50 ), leaf temperature: ±0.2℃. This instrument is widely used to analyze the photosynthesis capacity of plants, that is, the health status of plants; to analyze the true nitro demand of plants and to help understand the lack of nitro in the soil or whether excessive nitrogen fertilizer is applied; to identify the chlorophyll content of plants It is easy to extract and other research projects.
