[0054] To further optimize the solution, the top surface of the sediment 10 is tilted so that the sediment 10 is sloped, which is used to simulate the natural sediment form of mangroves. By simulating the ecological environment for the growth of mangroves and using the controlled variable method to explore the most suitable growth conditions, the experimental purpose is achieved.

[0056] Such an arrangement allows microorganisms to exchange substances with the sediment 10 through the porous ceramic plate 7. By inoculating different types of microorganisms on the porous ceramic plate 7, the effects of different types of microorganisms on the growth of mangroves can be explored.

[0057] According to a further optimized solution, the height of the sediment 10 is 3 cm to 10 cm.

[0058] To further optimize the solution, a water inlet 18 and a water level observation window 19 are installed on the water tank 1, and a scale 20 is provided on the water level observation window 19; the water inlet 18 is used to add seawater to the water tank 1, and the scale 20 on the water level observation window 19 is used to observe the water level in the water tank 1 to ensure that there is enough seawater in the water tank 1 for the incubator 3 to use.

[0059] The solution was further optimized, and the dimensions of the water tank 1 and the incubator were both 168cmx58cmx40cm.

[0060] The mangrove seedlings of the utility model are cultured in a culture box 3, which contains 500g of mangrove sediment 10 (dry weight) and 1000m artificial seawater (high tide level), the target pollutant is EtFOSA, and the concentration is 50μg / kgdw, and one one-year-old Kandelia candel seedling is planted in each culture box 3, and the high tide level, mid-tide level and low tide level are controlled at 8h, 8h and 8h respectively every day;

[0061] Kandelia candel seedlings were planted artificially in the laboratory, with the aboveground height of about 30 cm, and other growth conditions such as pH, temperature and nutrients were controlled by a soil conditioning system; the absorption time was 0, 4, 8, 12, 24, 48, 72, 96, and 120 h, and 3 parallels were set at each time point, and fresh roots were collected and stored at -80 °C for later use;

[0062] The experiment was conducted in a greenhouse. During the experiment, each group of mangrove plants was randomly placed. The water evaporation was calculated by weight method and supplemented with an equal amount of deionized water. [Before the measurement, the mangrove culture device was placed on an electronic scale and its initial mass (M1) was recorded. After the above time point, the culture device was placed on an electronic scale and weighed again, and its final mass (M2) was recorded. According to the principle of conservation of mass, the water evaporation is equal to the difference between the initial mass and the final mass, that is, ΔM = M1-M2. This method is a rough calculation, and the growth of mangroves and the absorption of soil water need to be considered.]

[0063] For microbial compartments, it is necessary to record the types of inoculated microorganisms and their initial numbers, sample the microorganisms in the compartments regularly, analyze the changes in the microbial populations, and record the growth parameters of mangroves, such as plant height and crown width, to evaluate the impact of microbial compartments on mangrove growth. It is also necessary to reflect the growth status of microorganisms by measuring the metabolic activity of microorganisms, such as enzyme activity, respiration and other indicators, in order to analyze the interaction and influence between mangroves and the microorganisms in the microbial compartments.
