[0055] Example 2

[0056] Taking Ge Xian Mi as an example, the ecological simulation cultivation method of Ge Xian Mi uses the culture system described in Example 1 for cultivation, which specifically includes:

[0057] Cultivation site and equipment: Take glass greenhouse or plastic greenhouse as the cultivation site, put the cultivation system in the cultivation site, put the perforated culture plate on the multi-layer cultivation rack, and the interval between each layer of the multi-layer cultivation rack is 30cm~ 40cm, the hole diameter of the culture plate 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 Gexian rice 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 by the shading net. Commonly used light sources ar...

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...
