Simple method for cultivating nostoc commune and cultivating device

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

A kind of simple cultivation method and cultivation device of ground fungus technical field 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 Nostoccommune 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,...

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
