Embodiment 1

[0055] The Nostoc algae shallow 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 shallow culture trays 2. 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 drip port 12; Below any one of the horizontal support bars 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 tank 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 drip port 12 through the culture fluid delivery pipe...

Embodiment 2

[0059] 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:

[0060] Cultivation site and equipment: use glass greenhouse or plastic greenhouse as the training site, place the culture system in the training site, place the shallow culture tray on the multi-layer culture rack, and the interval between each layer of the multi-layer culture rack is 30 cm ~40cm, the aperture of the shallow culture plate is 1-4mm, and the distance between the drip port and the top layer of the multi-layer culture rack is set to 40cm-50cm;

[0061] 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 alga superficial layer culture system and culture method. The system comprises a culture solution recovery tank (7), a multi-layered culture stand (1), a plurality of lighting devices (3), a recovered liquid filtering system (6) and at least one liquid dropping opening (12). The method comprises the following steps: placing a superficial layer culture disc on the multi-layered culture stand, wherein the alga species for inoculation is an alga species obtained by axenic cultivation with the diameter of 1-2mm; uniformly paving the alga species on the superficial layer culture disc during inoculation, wherein the inoculating density is controlled at 0.5g / cm<2> to 1g / cm<2>, and the inoculating thickness is 1cm-2cm; and spraying the culture solution to the culture and controlling the light and the temperature of the culture solution. The system does not need a special air pump to increase oxygen and carbon dioxide. The culture method is simple in step and cancels the processes such as ventilating, cleaning, changing the culture solution and the like. Over 60% of water can be saved, and over 50% of electricity can be saved. Pollution caused by impure algae can be effectively eliminated, and common nostoc is not easy to crush.

Description

Technical field [0001] The present invention is a biotechnology field, which is specifically belonging to a shallow culture system and training method of rosary algae. Background technique [0002] Gexianmi scientific name "Domestic ball -like pearl algae" ( Nostoc SPHAEROIDS KUZ ), Gexian Mi is a multi -cell group with a spherical shape. It has a common glue clothing sheath outside its silk, which is dark green. The diameter of the group can reach 5 cm.Medical books such as "Famous Medicine", "Compendium of Materia Medica", "Medicinal Exam", "Compilation of Chinese Herbal Medicine" and other medical books believe that Ge Xianmi has a bright and qi, cure night blindness, relieve heat and clear, eliminate fatigue, treat burns, and have both beauty and beautyFor the effects, because of its mild medicinal properties, long -term consumption has the effect of health and beauty. [0003] Gexian rice has a very high nutritional value and contains 18 amino acids. Among them, eight essent...
