Description

Suspended composite double-layer culture bag for fresh water microalgae culture Technical Field The utility model relates to the technical field of microalgae cultivation, in particular to a suspended composite double-layer cultivation bag for freshwater microalgae cultivation. Background Microalgae belong to algae, are a subset of algae, and particularly belong to a micro-algae population which can be observed by means of a microscope, and are usually only a few micrometers to hundreds of micrometers, lack differentiation of typical plant organs such as roots, stems, leaves and the like, and have relatively simple cell structures. Microalgae are miniature populations in algae, and have biological characteristics and wide application value. Microalgae are not strictly taxonomic terms, but refer to microscopic populations of microalgae, and common economic microalgae include haematococcus pluvialis, chlorella and the like. At present, the artificial culture of fresh water microalgae in the prior art can be divided into 1, and the culture is carried out outdoors by adopting a closed glass pipeline, so that the temperature is required to be proper, for example, haematococcus pluvialis is suitable for growth at the temperature of about 25 ℃. The temperature difference is not large all the year around in Yunnan, and the temperature is about 25 ℃ in most of the time, so that the haematococcus pluvialis is cultivated outdoors in some regions of Yunnan by using a closed glass pipeline. Because the natural air temperature cannot be kept at a constant temperature completely, the temperature is regulated by water circulation in Yunnan. The closed glass pipeline can effectively control the environment, but the cultivation mode occupies a large area, and the equipment cost and the operation cost are high. 2. Constructing an open pond on the ground, adding a culture medium into the pond for culturing, and controlling the temperature for culturing the fresh water microalgae in the pond. The pool cost is low, but the environment is uncontrollable, the pool is easy to infect mixed bacteria and protozoa, the growth of algae is endangered, and the harvest of algae is low. 3. Hanging cultivation by using a transparent plastic bag, and conveying the algae liquid into the transparent plastic bag for cultivation. The method has low equipment cost, can effectively control the culture environment, but is independent among bags, is only suitable for small-scale culture, and is generally suitable for culturing algae. Therefore, the growth of the fresh water microalgae needs to comprehensively consider various factors such as illumination, temperature, nutrient salts, pH, a culture system and the like, and different types and environments need to be optimized in a targeted manner. In summary, the present application provides a suspended composite double-layer cultivation bag for fresh water microalgae cultivation. Disclosure of Invention The utility model aims to provide a suspended composite double-layer culture bag for fresh water microalgae culture.
