Fungus cultivation technology and cost

Wood ear is an edible fungus and also a good health food. It has high nutritional value. As people's living standards improve, the market demand for wood ear continues to grow. Let's talk about the cultivation technology and cost of wood ear.

1. Cost of growing fungus

The profit of planting wood ear mushrooms on the ground is about 10,000 to 15,000 yuan per mu; the profit of planting wood ear mushrooms in hanging bags is about 30,000 to 40,000 yuan per mu. Different planting methods will result in different planting costs. Generally speaking, planting wood ear mushrooms requires purchasing production equipment worth about 1,800 yuan, and labor costs are around 6,250 yuan. The total cost is approximately 17,300 yuan per acre.

2. Fungus cultivation technology

1. Bacteria selection

The cultivation of black fungus begins with the selection of high-quality strains. High-quality strains ensure the health and strength of the mycelium, and are the basis for obtaining high-yield and high-quality black fungus.

2. Matrix formula

The culture medium of black fungus is generally made of wood materials, such as corn cobs, sawdust, wood chips, etc. Organic waste such as tofu dregs and corn stalks can also be used. These substrates are rich in nutrients and are conducive to the growth and development of mycelium.

3. Mycelium inoculation

Inoculate high-quality fungus strains into the substrate, and let the hyphae grow to form the mycelium of black fungus. During the mycelium growth stage, appropriate temperature and humidity should be maintained to promote rapid growth of mycelium.

4. Conditional regulation

During the mycelium growth period, environmental conditions, including temperature, humidity, and ventilation, need to be adjusted according to the needs of mycelium growth. Maintaining a suitable growth environment helps to increase the biomass of mycelium.

5. Forming the cap

When the mycelium grows to a certain extent, a cap, which is the body of black fungus, is formed on the surface of the mycelium. After the mycelium forms a cap, the black fungus begins to germinate. At this time, the ventilation volume should be increased and the humidity and temperature should be maintained at appropriate levels to facilitate the formation of a complete cap and rapid germinability.

6. Harvest

The black fungus is generally harvested 7-10 days after the fungus has grown. The black fungus with good growth and complete shape should be picked. After harvesting, the black fungus can be initially cleaned and decontaminated, and then stored in an environment with suitable low temperature and humidity to extend its shelf life and facilitate sales.
