Chlorophyll meter helps understand changes in chlorophyll content during plant growth Chlorophyll meter, as the name suggests, is a special instrument used to determine the chlorophyll content of plants. The instrument can measure the chlorophyll content of plants in time, enabling us to understand the growth status of plants. In all plant researches, we often use the chlorophyll meter to measure the chlorophyll content of plants and use their measured chlorophyll content to guide us to conduct scientific and rational fertilization. This is related to the use of SPAD- The 502 Chlorophyll Content Analyzer measures the chlorophyll content and guides the application of nitrogen fertilizer. It can reduce the use of 10% nitrogen fertilizer without reducing the crop yield. However, the chlorophyll content change trend during the growth of the plant is relatively small. Understanding and analysis, now is the use of chlorophyll meter to track the growth of sea-island cotton. By using the chlorophyll meter to determine and analyze the chlorophyll content in different growth stages of sea-island cotton, it was found that the change law of sea-island cotton during different growth periods is not the same. From the seedling stage to flowering stage of island cotton, it is The change in chlorophyll content is almost constant, but with the continuous growth of seaweed, the chlorophyll content gradually increases from the flowering stage to the boll stage, until the chlorophyll content in the boll stage reaches the highest value, followed by the chlorophyll content. At the beginning of the decline, the chlorophyll content in sea-island cotton began to slowly decompose until it was finally harvested. This change in chlorophyll can also reflect a change in plant nitrogen content and demand. At this time we can determine the nitrogen content of the plant from time to time, and then according to the demand for nitrogen in this stage, to properly fertilize or supplement fertilizer, in order to increase the growth of the crop. The change trend of chlorophyll content in sea-island cotton is the same, and the change trend of chlorophyll content in other plants also has a certain change pattern. The chlorophyll content in the seedling stage is relatively low, and the chlorophyll content will increase with the growth time. Gradually increase slowly until after the crop matures, so when using the chlorophyll meter to understand the nitrogen deficiency of the plant, combine the different growth periods of the crop and plant the crop in different areas. To ensure the accuracy of the measurement results.
