Problems solved by technology

[0004] At present, natural and artificial light sources are used for large-scale cultivation of seaweed. Under natural light conditions, the temperature and light intensity vary with regions, seasons, and day and night, which seriously affects the absorption of light energy by cells and the growth of biomass; artificial light sources mainly include cool white Fluorescent tubes and high-pressure mercury lamps, the light source consumes a lot of energy, cannot be placed underwater, absorbs a lot of light energy as the algae grows, and there is no light in the depth of the liquid layer, resulting in uneven light in the incubator, which is not conducive to the growth of algae

Embodiment 1

[0015] Take salina and isochrysis algae species (the algae species are taken from the microalgae room of Ocean University of China), dilute with sterile culture medium, centrifuge, wash, and divide 20ml of suspended algae liquid into 300ml triangular flasks, each algae species A total of 6 styles, divided into two groups, one group is irradiated with blue LED linear light strip with a center wavelength of 450nm and a bandwidth of 30nm, the other group is irradiated with white light (fluorescent tube), the illuminance varies between 200-2800lx, and the water temperature is 20- At 25°C, the light cycle is 12 hours a day, and the culture is continued for 1-2 weeks. After testing, the biomass of Salina salina and Isochrysis irradiated by blue light increased by 13.5% and 16.8% respectively; the content of intracellular polysaccharide increased by 14.3% and 9.7% respectively.

Embodiment 2

[0017] Take salina and isochrysis algae species (the algae species are taken from the microalgae room of Ocean University of China), dilute with sterile culture medium, centrifuge, wash, and divide 20ml of suspended algae liquid into 300ml triangular flasks, each algae species A total of 6 patterns are divided into two groups, one group is irradiated with red LED linear light strip and area array light source with a center wavelength of 655nm and a bandwidth of 30nm, and the other group is irradiated with white light (fluorescent tube), and the illuminance varies between 500-3000lx , the water temperature is 20-25°C, the photoperiod is 14 hours a day, and the culture is continued for 1-2 weeks. After testing, the biomass of Salina salina and Isochrysis irradiated by red light increased by 26.4% and 33.1% respectively; the content of intracellular polysaccharide increased by 19.7% and 12.5% ​​respectively.

Embodiment 3

[0019] Take salina and isochrysis algae species (the algae species are taken from the microalgae room of Ocean University of China), dilute with sterile culture medium, centrifuge, wash, and divide 20ml of suspended algae liquid into 300ml triangular flasks, each algae species A total of 6 styles, divided into two groups, one group is irradiated with the above-mentioned blue and red light strips and area light source, the other group is irradiated with white light (fluorescent tube), the illuminance varies in the range of 800-4000lx, and the water temperature is 20-25 ℃, the light cycle is 14 hours per day, and the culture is continued for 1-2 weeks. Tests show that the biomass of salina and isochrysis increased by 36.2% and 46.5% respectively when irradiated by blue light and red light compared with white light; the content of intracellular polysaccharide increased by 26.1% and 20.4% respectively.

Abstract

A method for using monochromic LED light to promote the growth of seaweed includes such steps as providing blue LEDs and red LEDs, cornecting them to beeorne a series or array of LEDs, putting them in sealed transparent water-proof material, and arranging them in ceclture pool of seaweed. It can promote the photosynthesis of seaweed.

Description

technical field [0001] The invention relates to a method for accelerating the growth of algae and improving the quality of the algae by using an LED monochromatic light source. Background technique [0002] As the main source and an indispensable part of human food, the development potential of terrestrial plants has come to an end. In order to obtain longer-term food supply and more abundant food sources, human beings gradually turn their attention to the vast ocean and use the plants grown in the ocean As a new food source, plants have become a development trend, and the research and development of marine plants has become increasingly significant for future economic and social development. How to develop marine plants will become the theme of the agricultural revolution in the 21st century. [0003] As one of the most important marine plants for human beings, seaweed is the main source of oxygen during the formation of the earth's atmosphere, and has played a huge role i...
