Production line for microalgae active cell nutritional repair liquid

Abstract

The invention discloses a production line for a microalgae active cell nutritional repair liquid and belongs to the technical field of microalgae production. The production line, according to the technical scheme, includes the following production zones: a single cell selection zone, an early stage amplifying culture zone, a final stage amplifying culture zone, and a mixing zone; wherein a plurality of culture sub-zones are arranged in the final stage amplifying culture zone, walking pathways being reserved between adjacent culture sub-zones; each culture sub-zone includes a plurality of culture apparatuses, each of which includes a culture bucket having an upward opening. A flexible transparent culture bag is placed in each culture bucket and is used for accommodating algae liquid. A topopening is formed in the top of each culture bag and communicates internal and external spaces of the culture bag. A top cover is detachably fixedly connected to each top opening. A gas inlet, a gas outlet and a liquid outlet are disposed on the top cover. The production line can improve efficiency of production operation and improve culture efficiency.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to a production line of microalgae active cell nutrient repair liquid. Background technique [0002] When the soil fertility level cannot meet the nutrients required for plant growth, the soil needs to be fertilized. Chemical fertilizers are currently widely used fertilizers. However, the negative effects of chemical fertilizers cannot be ignored: the raw materials for the production of chemical fertilizers contain Zn, Heavy metals such as Cu, Co, and Cr, these heavy metals are applied to the soil with chemical fertilizers, and cause the accumulation of heavy metal elements in the soil, which are absorbed into the plants through plants, affecting plant growth and the quality of agricultural products; chemical fertilizers will reduce soil microorganisms The quantity and activity of soil microorganisms, thereby reducing the transformation of organic matter in the soil, ...

[0002] When the soil fertility level cannot meet the nutrients required for plant growth, the soil needs to be fertilized. Chemical fertilizers are currently widely used fertilizers. However, the negative effects of chemical fertilizers cannot be ignored: the raw materials for the production of chemical fertilizers contain Zn, Heavy metals such as Cu, Co, and Cr, these heavy metals are applied to the soil with chemical fertilizers, and cause the accumulation of heavy metal elements in the soil, which are absorbed into the plants through plants, affecting plant growth and the quality of agricultural products; chemical fertilizers will reduce soil microorganisms The quantity and activity of soil microorganisms, thereby reducing the transformation of organic matter in the soil, the decomposition of minerals and the degradation of toxic substances; long-term application of chemical fertilizers will aggravate the acidification of the soil, aggravate soil compaction, inhibit the development of plant roots, and seriously reduce the stress resistance of plants. sex
