Embodiment Construction

[0014] The construction method of the seaweed seedling bank system of the present invention refers to the construction method of seaweed seeds, seedlings and adult seaweeds.

[0015] (1) Select a cofferdam pool site suitable for seaweed growth and build a cofferdam pool. The cofferdam pool site requires a fine sand particle size of 0.02 to 80 microns, a thickness of more than 12 cm, and an organic matter content of 2% in the fine sand; At least 24 days per month can enter the water during the high tide period, the maximum water temperature cannot exceed 30°C, and the duration of the water temperature at 30°C cannot exceed 10 days;

[0016] (2) Seaweed seedling cultivation: After the spores mature, regularly get healthy and mature tetrasporocyte seaweed from the sea, about 500g of each tree, remove its side branches, rinse under tap water and remove the dirt on its surface with a hair brush, and then clean it The algae were washed twice with sterilized seawater, then cut into a...

Abstract

The invention relates to a large-scale seaweed seedling culturing and transplanting method. The large-scale seaweed seedling culturing and transplanting method includes the following steps that a cofferdam pool field suitable for growing of seaweed is selected, a cofferdam pool is built, construction of an artificial seaweed field is performed in the selected cofferdam pool in the manner of transplanting adult seaweed and sowing seaweed seeds; the seaweed field constructed in the cofferdam pool is regularly tracked and observed, complementary planting of adult seaweed or complementary sowing of seaweed seeds is performed, after a seaweed seedling bin of the cofferdam pool is built and a stable state is reached, the adult seaweed or the seaweed seeds are collected from the seedling bin of the cofferdam pool, and transplantation of seaweed plants is performed.

Description

technical field [0001] The invention relates to a method for constructing a seedling bank, in particular to a large-scale seaweed seedling raising and transplanting method. Background technique [0002] Seagrass is a marine monocot angiosperm. Seagrass in the world is divided into 6 families and 14 genera, with a total of 66 species. It is known that there are 10 genera and 20 species in the Chinese sea area (such as Zostera marina L, Zostera caespitosa Miki, Zostera japonica Ascherson&Graebner , Phyllospadix iwatensis Makino). The distribution area of ​​seagrass accounts for 0.1% to 0.2% of the global ocean area, and seagrass grows in tropical, temperate and arctic regions. Seagrass fields, coral reefs and mangroves are three typical marine ecological maintenance systems, which can stabilize the bottom of the seabed, alleviate the erosion of waves on the coast, improve water quality, provide important primary productivity, provide food web support for secondary biological ...
