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. Attached below figure 1 Taking the construction of the eelgrass seedling bank system as an example in detail:

[0015] 1. Select a cofferdam pond site suitable for the growth of eelweed and build a cofferdam pond.

[0016] First of all, conduct a thorough investigation of the local conditions of the cofferdam pool, mainly including the bottom quality of the cofferdam pool, preferably fine sand or silt, the particle size of fine sand is generally 0.02 to 80 microns, and the thickness is preferably more than 12 cm , There is no special requirement for the proportion of sediment, and the organic matter content of sediment or fine sand is 2% is the best.

[0017] Secondly, in the cofferdam pool, there are at least 24 days per month when sea water can enter the high tide period, the maximum water temperature ...

Abstract

The invention discloses a construction method of a seaweed germchit bank system. The method comprises the following steps: 1, selecting a cofferdam pond place which is suitable for the growth of seaweeds and building a cofferdam pond; 2, constructing an artificial seaweed land in the selected cofferdam pond through adult seaweed transplanting and seaweed seed sowing; 3, carrying out tracking observation on the seaweed land constructed in the cofferdam pond, and after-transplanting adult seaweeds or resowing seaweed seeds; and 4, after the seaweed germchit bank in the cofferdam pond is constructed and enters into a stable state, collecting adult seaweeds or seaweed seeds from the seaweed germchit bank in the cofferdam pond. The cofferdam pond place is selected according to the following conditions: bottom sand is 0.02-80 micrometers and 12 centimeters in thickness and the organic content of sand is 2%. The construction method of the seaweed germchit bank system can continuously provide adult seaweeds and seaweed seeds required by ecological restoration and artificial seaweed land construction, and therefore seaweeds in natural sea areas are prevented from being damaged and the sustainable and healthy development of the marine ecosystem is maintained.

Description

technical field [0001] The invention relates to a construction method of a seedling bank, in particular to a systematic construction method of seaweed seeds, seedlings and adult seaweed banks. Background technique [0002] Seagrass is a marine monocotyledonous angiosperm. There are 66 species of seagrass in 6 families and 14 genera in the world. It is known that there are 10 genera and 20 species in the Chinese sea area (such as Zostera marina L., Zostera caespitosa Miki, Leaf algae 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 ...
