Embodiment 1

[0048] Embodiment 1: Preservation of germplasm resources of Sargassum sargassum

[0049] (1) Turn on the instrument, put an appropriate amount of seawater into the seawater recovery pool 6, turn on the temperature control system to keep the seawater temperature at 16°C; turn on the seawater delivery pump 7 and delivery controller 9, and spray the culture net tray 2 to keep it moist ; Simultaneously, turn on the lighting system LED lamp 12 to control the lighting to 4000lx, and adjust the switch timing controller 13 to control the lighting cycle as: light: dark=12:12h.

[0050] (2) Select a well-grown Sage algae, soak the main branch of the algal strain with alcohol with a volume concentration of 75% for 30 seconds, and quickly wash it with a large amount of sterilized seawater for 3 to 4 times; cut off the main branch of the algal strain, and the length of the fragment is 5 to 6 cm , wash carefully with sterilized seawater, remove the surface attachments, and evenly fix it on ...

Embodiment 2

[0059] Embodiment 2: the preservation of sea millet germplasm resources

[0060] (1) Turn on the instrument, put an appropriate amount of sterilized seawater into the seawater recovery pool 6, open the temperature control system 8, and keep the seawater temperature at 14°C; Wet; at the same time, turn on the lighting system LED light 12 to control the lighting to 3000 lx, and adjust the timer 13 to control the lighting cycle as: light: dark = 12:12h.

[0061] (2) Select an excellent variety of sea millet with strong growth potential and high alginate content, use a brush and tweezers to remove the sundries and attached organisms on the surface, soak the main branch of the algae strain with alcohol with a volume concentration of 75% for 30 seconds, and disinfect it with a large amount of water. Quickly wash the seawater 3 to 4 times; cut off the main branch of the algae strain, the length of the fragment is 5 to 6 cm, and evenly fix it on the culture net plate 2, and the densit...

Abstract

The invention discloses a device and method for sargassaceae seaweed germplasm preservation. The device includes a culturing system, a cycling filtration system, a spraying system and an illumination system; the technology and equipment required by the culturing system are simple, the investment is small, the production cost is low, a culturing device and a long-term culturing method are provided for living-body germplasm preservation and eco-physiological characteristic study of sargassaceae seaweed, and according to the culturing device and the long-term culturing method, observation can be conducted at any time, and experimental operation is simple and easy to implement. When the germplasm preservation device is used for sargassaceae seaweed culturing, the dry exposure state under the natural ecological environment is simulated, the duration of contact between the seaweed and air is long, the photosynthetic efficiency is high, and the seaweed more easily grows. When the method is used for seaweed germplasm preservation, epiphytic algae is little, the stress resistance is good, and the seaweed germplasm can be preserved in a room for a long time; according to the method, management in the seaweed germplasm preservation process is convenient, little water is used, sea water is recycled, and more than 80% of water can be saved.

Description

technical field [0001] The invention relates to a large seaweed germplasm preservation device and preservation method, in particular to a Sargassum family seaweed germplasm preservation device and preservation method, and belongs to the technical field of algae germplasm resource preservation and cultivation. Background technique [0002] Sargassum family seaweed is a kind of large seaweed with high economic value. It has important development and application prospects in the fields of aquaculture, medicine and health care, biological products, food processing, aquatic feed, seaweed fertilizer, chemical industry and marine ecological environment protection. In recent years, due to the pollution and over-harvesting of the near-shore sea area, its resources have declined sharply, and the lack of good provenance has seriously restricted the development of the entire industry. Therefore, large-scale breeding of germplasm resources with excellent traits is a key way of industrial...
