Embodiment 1

[0053] The Nostoc algae ecological simulation culture system includes a culture solution recovery tank 7, and also includes a plurality of vertical support rods 13 for supporting and a plurality of horizontal support rods 14 for placing the culture tray 2 with holes. Layer culture frame 1, multiple lighting devices 3, recovered liquid filtration system 6, culture liquid delivery controller 10, culture liquid delivery pipeline 11, at least one nozzle 12; Underneath the layer horizontal support bar 14, the bottom of the multi-layer culture frame 1 is provided with a culture solution recovery tray 4, and the culture solution recovery tray 4 communicates with the culture solution recovery pool 7 through the recovery pipeline 5 and the recovery solution filtration system 6; The culture fluid recovery pool 7 is connected with a culture fluid delivery pump 8 and a temperature control device 9; the culture fluid delivery pump 8 communicates with the nozzle 12 through the culture fluid ...

Embodiment 2

[0056] Taking Gexianmi as an example, the method for cultivating Gexianmi ecological simulation is cultivated with the cultivation system described in Example 1, which specifically includes:

[0057] Cultivation site and equipment: use glass greenhouse or plastic greenhouse as the training site, place the culture system in the training site, place the culture plate with holes on the multi-layer culture rack, and the interval between each layer of the multi-layer culture rack is 30cm~ 40cm, the hole diameter of the culture plate with holes is ≤1mm, and the distance between the nozzle and the top layer of the multi-layer culture rack is 40cm-50cm;

[0058] Light source: The light intensity required for the growth of Gexianmi is 1000-8000lx. When the natural light intensity meets this condition, artificial light sources can be used. When the light intensity is too high, the light intensity needs to be reduced through the sunshade net. Commonly used light sources are waterproof fl...

Abstract

The invention provides a nostoc algae ecological-simulation culturing system and a culturing method. The culturing system comprises a culturing solution recovering tank (7), a multi-layer culturing shelf (1), multiple light irradiation device (3), a recovered solution filtering system (6) and at least one spray nozzle (12). The culturing method comprises the following steps: putting a culturing tray with holes on the multi-layer culturing shelf; when inoculating, uniformly spreading algae seeds in the culturing tray with holes, wherein the inoculation algae seeds obtained by aseptic culturing are the algae seeds with the diameter of 1-2mm, the inoculation density is controlled to be 0.5-1g / cm<2> and the inoculation thickness is 1-2cm; spraying a culturing solution on cultures, and controlling light irradiation and culturing temperature. According to the method, 80% of water can be saved, spheres do not rupture easily in the process of culturing nostoc commune, the wild algae pollution resisting capability of the nostoc commune is high, the rate of wild algae pollution is low, and the content of dry matter in the produced nostoc commune can be up to 8%.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation, in particular to an ecological simulation cultivation system and a cultivation method of algae of the genus Nostoc, in particular to a cultivation system and a cultivation method of Gexianmi. Background technique [0002] Gexianmi is a kind of rare freshwater cyanobacteria that can be used for both medicine and food, which is a special product in Zouma Town, Hefeng, Hubei, my country. Because Ge Hongxian, an alchemist, medical scientist, and Taoist theorist known as Ge Xiangong in the Eastern Jin Dynasty, and the emperor and prince fell ill after eating this for a long time The body became smoother, so it was named "Ge Xianmi". It belongs to Cyanophyta, Cyanophyceae, Hormogonales, Nostocaceae, and Nostoc together with Nostoc commune vanch. and N.flagelliforme. (Nostoc), scientific name "Nostoc sphaeroids kuz". Gexianmi is a multicellular population, its main shape is spherical, and a f...
