Problems solved by technology

However, Spirulina has a strong adsorption capacity. The use of chemical fertilizers will easily cause chemical substances to remain in Spirulina, and the heavy metals in Spirulina will easily exceed the standard. The use of chemical fertilizers will pollute the water environment, and the investment in environmental protection is also large.

Embodiment 1

[0017] This embodiment includes the following aspects:

[0018] 1. Selection of breeding base: strictly follow the requirements of pure organic breeding base without pollution. You can choose that there should not be any industrial and mining production enterprises within a radius of 30m, do not contact with residential areas, and avoid the breeding environment (mainly air) caused by industrial production and life. , water quality) pollution.

[0019] In this embodiment, the organic spirulina breeding base is selected in Danzhou, Hainan. There is no industrial pollution source within 10 kilometers around the base, and there are only trees around the base, completely isolated from residential areas. The sun is shining and the air is fresh.

[0020] 2. Nutrients for cultivating spirulina: select high-quality organic fertilizer concentrate: Riying brand liquid compound fertilizer produced in Hainan.

[0021] 3. Specific breeding operations: Take the 1000 square meters cement r...

Embodiment 2

[0024] Specific farming operation: Add enough non-polluted groundwater in the area to the runway pool, add the Longan liquid bio-organic fertilizer concentrate produced by Hainan Jiangdao Company according to the weight ratio of pure water and organic fertilizer concentrate 1000:1, and then add the spiral Algae species. By the agitation of the stirrer, the spirulina is allowed to carry out normal photosynthesis, and when the pH is raised to 10 from 8.5, it is cultivated for 5-6 days, and when containing 0.5-0.7 gram of spirulina dry powder in every kilogram of culture solution (that is, adopting OD560 to measure the number as 1.0-1.2), using the method of drop filtration to harvest, only harvest 50% of the culture solution of spirulina, and the water after harvesting and filtering is returned to the original runway pool for recycling. Add the concentrated solution of organic fertilizer according to the concentrated solution of purified water and organic fertilizer in a weight ...

Embodiment 3

[0026] Concrete breeding operation: Take the cement runway pool of 1000 square meters as an example, add enough non-polluting groundwater in this area in the runway pool, add the concentrated solution of organic fertilizer by the concentrated solution of pure water and organic fertilizer 1000: 5 weight ratio, pass The agitation of the mixer allows the spirulina to carry out normal photosynthesis, and the pH is raised to 10 by 8.5, and the concentrated solution of the organic fertilizer is supplemented by adding the concentrated solution of the pure water to the concentrated solution of the organic fertilizer at a weight ratio of 1000: 2, and simultaneously charged with carbon dioxide gas, so that The pH of the culture medium returns to 8.5-9. After 5-6 days of cultivation, the method of drop filtration is used for harvesting. Only 45% of the culture medium of spirulina is harvested, and the collected and filtered water is returned to the original runway pool for recycling. , ad...

Abstract

The invention discloses a method for cultivating organic spirulina in large areas, which comprises the following steps: 1. the selection of a cultivation base; 2. choosing the concentrated solution of organic fertilizer with fine quality for use; 3. Cultivation; a track pool is added with enough purified water, the concentrated solution of the organic fertilizer according to the 1000: 1-5 weight ratio of the concentrated solution of the purified water and the organic fertilizer and spirulina seed; the photosynthesis is carried out on the spirulina by stirring; the cultivation is carried out; when per kilogram of culture fluid contains 0.5-0.7 g of spirulina dry powder, the collection is carried out; and the concentrated solution of the organic fertilizer is supplemented again; meanwhile, the carbon dioxide gas is filled till the pH value of the cultivate fluid reaches 8.5-9 to cause that the spirulina continuously grow; the steps are cycled in sequence. In the method, the chemical synthetic fertilizer or the chemical treatment are entirely not used or basically not used, thus fundamentally solving the problem of the chemical substance residue of the spirulina products and the overproof of the heavy meta; of the spirulina, guarantying the organic performance and safety of the spirulina powder and increasing the yield of the products.

Description

technical field [0001] The invention relates to a culture of spirulina, in particular to a method for cultivating organic spirulina in a large area. Background technique [0002] Chemical fertilizers can rapidly promote the growth of Spirulina and increase the yield of Spirulina and are widely used. However, Spirulina has a strong adsorption capacity, and the use of chemical fertilizers may easily cause chemical substances to remain in Spirulina, and heavy metals in Spirulina may exceed the standard. The use of chemical fertilizers will pollute the water environment, and the investment in environmental protection is also large. Contents of the invention [0003] The purpose of the present invention is to: overcome the defect of using the prior art to make spirulina contain residual chemical substances, and provide a large-area cultured organic spirulina that can ensure the organic performance of algae powder and ensure that the various nutrients contained in spirulina a...
