Embodiment 1
[0030] Embodiment one, refer to Figure 1 to Figure 3 ,in figure 1 Shown in A is the state of seeds cultured in sterilized seawater with a salinity of 15, 15°C and shading conditions for 14 days, and B is the state where germinated seeds were transferred to sterilized seawater with a salinity of 25, and cultured for 15 days at 15°C and shading conditions State, C is sterilized seawater with a salinity of 30, 15°C, light of 3000lx, and seedlings cultivated for 7 days.
[0031] This embodiment includes the following steps:
[0032] (1) Configure seawater with salinity 15, salinity 25, and salinity 30
[0033] Slowly add distilled water to the seawater and keep stirring, measure the salinity of the seawater with a salinity meter, until the salinity reaches 15, 25, 30, stop adding distilled water;
[0034] Fill the prepared seawater with salinity 15, salinity 25, salinity 30 and normal salinity into the triangular flask respectively, and sterilize for 15 minutes in an autoclave...
Embodiment 2
[0044] Embodiment 2. The difference between this embodiment and Embodiment 1 is that in the step (4) of this embodiment, the seedling bases are connected in series with gridded hollow trays to form seedling base trays. The diameter of the hollowed-out square should be slightly smaller than the diameter of the "seedling base" to facilitate firm fixation. Specifically, the image 3 The shown seedling base is stuffed into the hollowed out part of the grid, and the number of grids can be customized according to the actual transplanting needs. Figure 5 For the combined seagrass skin, then cultivate the sea grass skin for 14 days at 15°C and 5000lx light conditions, refer to Image 6 , the seedlings are in good condition and ready for transplantation. Figure 7 It is a photo of the effect of transplanting the eelgrass artificial seagrass turf cultivated by the present embodiment. Dig a pit with a depth of 3 to 3.5 cm on the substrate of the transplanted sea area, bury the cultiv...
Embodiment 3
[0046] Embodiment 3 is different from the foregoing embodiments in that:
[0047] In step (2), wash the seeds with seawater of normal salinity for several times, then put them into a triangular flask, cultivate them under shading conditions at 15°C for 10 days, then place them in sterilized seawater with a salinity of 25°C, and cultivate them under shading conditions at 15°C 12d;
[0048] In step (3), place the seeds of the eel algae in sterilized seawater with a salinity of 30, culture at 15°C, and light of 4000lx, and develop the eel algae seeds into seedlings after 10 days;
[0049] In step (5), culture is carried out for 10 days at a temperature of 15° C. and a light of 6000 lx.
[0050] This embodiment also overcomes the shortcomings of the traditional recovery method of eelgrass seagrass beds, and the seedlings develop well.
