Method for cultivating spirulina

Abstract

This invention discloses a method for spirulina culture, which contains constructing culture environment of spirulina, confecting culture liquid, nursing during culture process, gathering and harvesting spirulina. Firstly construct culture environment of spirulina; then confect culture liquid, whose components and the mass proportions are as follows: NaHCO3 10-15Kg, KH2PO4 0. 1-0. 9Kg, microelement1-8Kg, pure crude water1 ton, and the culture conditions are as foolws: water temperature keeps at 25deg C- 35deg C, humidity keeps at 40íÒ-60íÒ, charge oxygen in the time of the day and illuminate for at least 12 hours a day; then gather the spirulina: flush the filter spirulina and test with pH paper, and it is up to grade when the paper showing neutrality; supplement nourishment: after series gathering, feed each nutrimental materials proportionally into culture crock, consquenty guarantee the spirulina get plenty nourishment. When the pH value of culture liquid ascends to 11, add NaHCO3 to maintain its pH value in 8-11. Continuely culture and harvest to keep the spirulina of certain density; add NaHCO3 to stabilize the pH value of culture liquid and accelerate growth and breeding of spirulina in the culture liquid.

Description

technical field [0001] The invention relates to a method for cultivating spirulina, in particular to a method for cultivating spirulina capable of industrialization and large-scale production. Background technique [0002] Spirulina is a light-energy autotrophic organism. At present, spirulina products have been used in the field of human consumption. Spirulina has good anti-virus ability and can effectively reduce blood sugar and cholesterol. It is a high-value medical and health care product. . [0003] The current large-scale cultivation of spirulina basically adopts open-air cultivation, using natural lakes or building large-scale cultivation ponds for cultivation. This cultivation method has the advantages of low cost, but the product quality is difficult to guarantee, the unit output is low, and it is easily affected by the environment. and seasonal effects. [0004] On February 8, 1995, the State Intellectual Property Office of China published an invention patent ti...

Problems solved by technology

[0003] The current large-scale cultivation of spirulina basically adopts open-air cultivation, using natural lakes or building large-scale cultivation ponds for cultivation. This cultivation method has the advantages of low cost, but the product quality is difficult to guarantee, the unit output is low, and it is easily affected by the environment. and seasonal effects

[0004] On February 8, 1995, the State Intellectual Property Office of China published an invention patent titled "New Method and Device for Spirulina Production". Promote the flow of the culture medium, and then install a filter to raise the liquid level, and at the same time filter the larger spirulina algae. Compared with the original method of cultivating spirulina in a square pond, the product quality and output have been significantly improved, and the cost is low and easy to use. promotion, but the modified plan cannot effectively change the defect that spirulina is easily affected by the environment when culturing spirulina, and open-air cultivation is easily polluted. This method of mixed cultivation in large ponds will affect the output and quality of the overall algal group after local pollution. Spirulina for effective artificial control

[0005] On February 5, 2003, the State Intellectual Property Office of China published an invention patent titled "A Method for Domesticating and Eating Fresh Spirulina". The temperature control device and the container can be cultivated outdoors and indoors. Indoor cultivation needs to increase the light. This scheme is simple in structure and suitable for family cultivation, and can be moderately artificially controlled. However, for large-scale cultivation of spirulina, this scheme is not perfect

[0006] On July 27, 1994, the State Intellectual Property Office of China published an invention patent titled "Closed Culture Method and Device for Spirulina". The aquaculture pipeline composed of multiple U-shaped tubes is connected by gas lift to circulate the culture solution and placed in the greenhouse for cultivation. Light and temperature control are added as needed. This solution better solves the problem that outdoor aquaculture is prone to pollution and seasons. The problem of the impact of environmental changes, and it can be well controlled artificially, and can be produced continuously on a large scale, but the structure of this scheme is relatively complicated, the cost is high, and it cannot solve the problem of the overall impact of algae groups after local pollution
