Problems solved by technology

At present, the cultivation methods of ground fungus are concentrated in culture vessels or artificial culture pools, which require corresponding vessels or artificial culture pools. The culture solution requires a special formula, and the culture solution needs to be replaced frequently. The cultivation cost is large and it is not suitable for large-scale Area cultivation

Embodiment 1

[0020] Such as figure 1 The cultivating device for ground fungus shown includes a frame 3 surrounded by plastic tubes, the frame 3 is provided with a cultivating net 4 with a mesh aperture of 0.5 to 3.0 mm, and pulleys 1 are arranged symmetrically on both sides of the frame 3, Pulley 1 is fixed with shelf, and pulley 1 is provided with suspension rope 2, and suspension rope 2 is fixedly connected with frame 3, and when the ground fungus on the cultivation net 4 is to be dried out like this, as long as pull suspension rope 2 to let framework 3 Hang up with training net 4, fix suspension rope 2 again and get final product. After drying out, just put down the suspension rope 2 and pull up the suspension rope 2 to drain water when harvesting simultaneously, which is also easy to harvest.

Embodiment 2

[0022] The preparation of the culture solution of simple cultured fungus: the quality of nitrogen in 100ml of culture solution is 0.5-2.0g (about 1.0g is better), and the quality of phosphorus is 0.2-0.8g (about 0.5g is better) as a standard. Mix the commercially available nitrogen and phosphorus fertilizers with boiled and filtered clean fresh water, and stir to make the culture solution. Nitrogen and phosphorus fertilizers can also be self-mixed with nitrogen and phosphorus fertilizers.

Embodiment 3

[0024] A kind of simple and easy cultivation method of Auricularia auricularia, in Erlenmeyer flask, add 2000ml of nutrient solution (the nutrient solution of above-mentioned embodiment 2, hereinafter the same), then inoculate 4~20g of Auricularia auricula and plant in Erlenmeyer flask, at temperature is 15 ℃~ Cultivate under the conditions of 25°C, light intensity of 1500-3000Lx, and light time of 10-14 hours until the cell density of the fungus in the culture solution in the Erlenmeyer flask reaches 50,000-100,000 / ml, and the first-class ground fungus culture is obtained material; move the above-mentioned first-class ground fungus culture into a plastic bucket, then add about 40,000ml of culture solution into the plastic bucket (other buckets and bags can also be used instead), and then keep the temperature at 20°C to 25°C and the light intensity at 3000°C. ~6000Lx, the light time is not less than 12 hours (13, 14, 15, 16, 18 hours, etc. can be used), cultivated under the con...

Abstract

The invention discloses a simple method for cultivating nostoc commune and a cultivating device. A plastic pipe is enclosed into a frame; the frame is provided with a simple cultivating device of a cultivating net with hole diameter being 0.5-3.0mm; and nutrient solution with simple prescription is used for preparing an artificial water body nostoc commune seedlings cultivating mode with each-level standard control condition and simple facility, and a natural water body nostoc commune cultivating mode with large-scale, open and large-area and simple facility, wherein the artificial water nostoc commune cultivating mode comprises a first-stage cultivation with a flask, a second-stage cultivation with a plastic bucket and a nostoc commune cultivation with a cement pool. The cultivating device is simple, convenient, economic and practical, and has the advantages of no soil amelioration, recycle and floating bed type. The cultivating method has the advantages of simple facility, standard cultivating condition and low cultivating cost, and is suitable for cultivating the nostoc commune in the natural water body with lager area.

Description

technical field [0001] The invention relates to a method for cultivating ground fungus, in particular to a simple cultivating method and a cultivating device for ground fungus. Background technique [0002] Nostoc commune is a combination of fungi and algae, and its symbiotic algae is Nostoc, which is a common nitrogen-fixing cyanobacteria. It belongs to Cyanophyta, Nostocaceae. Dark black, a bit like soaked black fungus, hence the name. The reproduction method of the fungus is that the algae filaments are separated into several algae segments by the heterocysts, which are easily separated from the heterocysts, and each algae segment grows into a filament through cell division. Heterospores and chlamydospores are produced on the filaments for vegetative reproduction. Ground fungus is widely distributed, mostly born on wet soil surfaces, and is most common on wetlands after rain in summer. It is rich in protein, multivitamins and minerals such as phosphorus, zinc and calc...
