The embodiment of the invention provides a method for quickly cultivating seaweed in a pond, and referring to fig. 1, fig. 1 is a schematic flow chart of the method for quickly cultivating seaweed in the pond. As shown in FIG. 1, the method for rapid cultivation in a seaweed pond comprises the following steps:
step 101, installing a supporting device at the bottom of a preset cultivation pond.
In this step, the pond bottom is mild, the elevation in pond is below the big sea tide level of predetermineeing, the pond bottom is provided with the gate, can regulate and control inside water exchange and the water degree of depth in pond.
The distance between the supporting device and the bottom of the pond is 5cm-10cm.
Optionally, the supporting device comprises a supporting frame, a grating plate and an iron bracket; the support frame is located the bottommost, the grid plate is arranged in the support frame upper strata, the iron support is arranged in grid plate upper strata.
Optionally, the distance between the support frame and the bottom of the pond is 5cm-10cm, and the support frame can be used for supporting the bottom of the grid plate. The size of the grid plate is 1.22m multiplied by 3.66cm, the thickness is 2.5cm, and the grid size of the grid plate is 3.8cm multiplied by 3.8cm; the grating plate is made of o-benzene resin; the grid plates can be used for planar support of iron supports. As shown in fig. 2, fig. 2 is a partial structural view of the iron bracket of the present invention; the iron support is in a strip-shaped interval structure, the size of the iron support is 60cm multiplied by 60cm, and the iron support is made of sheet iron.
It can be understood that the iron bracket is designed with less materials and low cost. The iron bracket can be used for supporting the sediment and reducing the sulfide content in the sediment; and convenient for the later stage of seaweed transplantation.
And 102, paving a fine mesh layer on the supporting device.
Wherein, the size of the fine mesh layer is matched with that of the iron bracket, and the size of the fine mesh layer is 60cm multiplied by 60cm, so that the fine mesh layer can be used for preventing the omission of sediments and seaweed.
Optionally, in a specific implementation, the fine mesh layer may be a jute bag sheet, and the jute bag sheet is made of jute fabric, and it can be understood that the jute bag sheet is degraded into a fertilizer along with a culture process, so that the jute bag sheet is environment-friendly.
103, paving calcareous sand and slow release fertilizer on the fine mesh layer.
Wherein the calcareous sand is a mixture containing fragments of coral or shell. The thickness of the calcareous sand is 7cm-10cm, and the composition granularity of the calcareous sand is 500um-6500um. The slow release fertilizer is doped into the calcareous sand, the slow release fertilizer can be granular, and the mass ratio of the slow release fertilizer to the calcareous sand is 1:1000.
specifically, the mass ratio of nitrogen to phosphorus to potassium of the slow release fertilizer is 25:14:12, the slow release fertilizer can promote the growth of the seaweed quickly.
It is understood that the calcareous sands can provide proper pH value for seaweed due to the alkali-containing substances, wherein the proper pH value is 8.0-8.5; the loose pore structure of the calcareous sand can provide dissolved oxygen for the root of the seaweed and can reduce the generation of seabed sulfides.
And 104, transplanting the seaweed plaques soaked by the phytohormones into the calcareous sand.
In this step, the plant hormone is a combination hormone including auxin, cytokinin and gibberellin. In specific implementation, the seaweed can be selected from egg She Xi saltgrass.
Specifically, the eggs She Xi saline grass plaques are placed in seawater prepared according to a certain plant hormone proportion, soaked for 48 hours, and then transplanted into calcareous sand by using a plaque method, the transplanting depth is-5 cm in the calcareous sand, the checkerboard arrangement can be adopted, and the coverage of the eggs She Xi saline grass plaques is about 16%.
It is understood that the ratio of the plant hormones auxin to auxin, cytokinin and gibberellin, and the concentration of the plant hormone in seawater affect the egg She Xi saltgrass plaque growth coverage. As shown in table 1, table 1 is the egg She Xi saline grass plaque coverage in the iron stent after 1 month of the experiment.
TABLE 1
It should be noted that when the coverage of the egg She Xi saline grass is more than 60%, the egg She Xi saline grass can be directly transplanted to the area needing repair by using an iron bracket. Plaques can be placed in a checkerboard manner, and maximum transplantation efficiency is achieved. The transplanted iron stent is not recycled, so that the content of sulfide in sediments can be reduced, and the growth and development of the seaweed are promoted.
