Embodiment 1

[0031] 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.

[0032] This embodiment includes the following steps:

[0033] (1) Configure seawater with salinity 15, salinity 25, and salinity 30

[0034] 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;

[0035] 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

[0045] 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

[0047] Embodiment 3 is different from the foregoing embodiments in that:

[0048] 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;

[0049] 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;

[0050] In step (5), culture is carried out for 10 days at a temperature of 15° C. and a light of 6000 lx.

[0051] This embodiment also overcomes the shortcomings of the traditional recovery method of eelgrass seagrass beds, and the seedlings develop well.

Abstract

Aiming at solving the existing problems that an existing repairing method of a zostera marina seagrass bed is low and a germination rate of seeds is low, the invention provides a cultivation method of zostera marina artificial sea turfs. Seed propagation is used in the cultivation process, existing seagrass bed resources do not need to be damaged, and a group genetic diversity of a repairing area is increased. A seedling grows in a 'seedling base' in an earlier stage, substrate particle size is small, nutrition is rich, rhizomes of the seedling grows fast, a survive rate of the seedling is high, adaptability to a transplant sea area is strong, and the cultivation method of the zostera marina artificial sea turfs is applicable to a new-built seagrass bed and overcomes the shortcoming that direct seed sowing is low in germination rate.

Description

[0001] Technical field [0002] The present invention is an ecological repair technology and application field, involving a method of cultivating the cultivation of artificial seagrass skin and using the artificial seagrass skin of large leaf algae. Background technique [0003] Seagrass is a high plant that lives in the sinking water environment of the ocean and has a complete rhizome leaf system.The area where seaweed gathers and grows can be called seagrass bed.Seaweed beds are one of the typical marine ecosystems with the highest productivity and biological diversity, and their ecological value is much higher than mangroves and coral reefs.Big leaves are typical representatives of seagrass and are widely distributed in my country, Liaoning, Hebei, Shandong and other regions.Large algae usually forms a large community in the shallow waters, and is an important part of the offshore ecosystem.In recent years, due to the changes in the natural environment and the influence of hum...
