The chlorophyll content of aquatic plants is the verification method for the eutrophication of water bodies. Eutrophication refers to the fact that under the influence of human activities, nutrient substances such as nitrogen and phosphorus enter the lakes, estuaries, bays and other slow-flowing bodies of water, causing algae and Other plankton blooms rapidly, the amount of dissolved oxygen in the water drops, water quality deteriorates, and fish and other organisms die. The degree of eutrophication of the water can be measured and analyzed by the chlorophyll meter to measure the chlorophyll content of aquatic plants. This article is to analyze the chlorophyll content of the re-forced flower using the chlorophyll meter.
Thalia dealbata is a genus of plants of the family Paphiopedilum. It is native to the tropical America. It is a long- standing, evergreen, and highly ornamental value. It is widely cultivated in the south of the Yangtze River basin in China. Therefore, it was selected as The object of measurement. The value measured by the chlorophyll meter is the SPAD value. By verifying various plants, it is found that the chlorophyll content is directly proportional to the SPAD value. Therefore, the SPAD value can represent the chlorophyll content, and the eleven control form during the experiment process. To measure, by measuring the degree of eutrophic water quality, it was found that the total amount of chlorophyll a, chlorophyll b, and chlorophyll re-exerted with different degrees of sewage treatment was significantly lower than that of the control group, which was related to the sewage stress. The results of studies on the decline of chlorophyll content in aquatic plants are consistent. This indicated that the chlorophyll synthesis of plants was hindered under stress conditions and the photosynthetic apparatus was damaged. At the same time, the impact of pollution sources on the chlorophyll content of re-affirmed chlorophyll content was verified. It was found that the plants treated with domestic sewage received relatively less damage, followed by industrial sewage, and the most serious urban sewage. This may be due to the higher BOD contained in municipal sewage. The content of the flowering plant is subjected to more severe environmental stress.
Therefore, in order to understand the degree of eutrophication of water quality, a chlorophyll meter can be used to measure the chlorophyll content of the plant and a simple analysis can be performed to understand the degree of eutrophication.
