Edible mushroom cultivation requires those basic knowledge

Basic knowledge of microbiology and agriculture.

The mycelium of edible fungi grows white, stout, dense, no peculiar smell, no wall off, no infection, no insect pests, and the age of the fungus is suitable.

The mycelium is robust, dense, pure in color, no peculiar smell, and no bacterial infection. Pest-free. The bacterial age is moderate.

I think there are many problems that often arise when cultivating edible mushrooms, such as the possibility of bacterial infection, the fact that we do not do enough when sterilizing the culture material, or the bacteria we cultivate carry the corresponding bacteria. The problem may also be that after inoculation, our mycelium will not germinate, or we have various unreasonable phenomena when batching, the strains we cultivate have corresponding quality problems, or the mycelium is slow to eat in the later stage of germination. <>

When we are cultivating edible mushrooms, it is very likely that there will be a phenomenon that mushrooms do not appear after the mycelium is full. The main reason for this phenomenon is likely to be related to the unsuitable ambient temperature, because the adaptability of different strains at different ambient temperatures is very different, and when our ambient temperature is higher or lower than the normal temperature, it is difficult to produce mushrooms. It may also be caused by the inappropriate carbon and nitrogen ratio in the culture material, because different strains have different formulas, and we can only make the most suitable carbon and nitrogen ratio culture material to make the edible mushrooms we grow grow normally.

There is also a possibility that due to insufficient light, some strains must have a certain amount of light exposure in the corresponding stage to be able to produce mushrooms normally. <>

In the process of edible mushroom cultivation, it is very likely that there will be symptoms of bad fungus, such as our mycelium grows slowly, or it will not germinate, and when it grows to a certain extent, it will not grow again. This is likely to be because there is more moisture in our culture material, resulting in poor air permeability, so a large number of bacteria are breeding, we should open the vent in time, ventilate, and increase a certain oxygen content to reduce the humidity in the culture material. <>

All in all, in the process of edible mushroom cultivation, we must pay attention to various common problems and take a more scientific way to solve them.

1: The mycelium germinates slowly, grows slowly, or does not germinate, and no longer grows when it grows to a certain extent; or the mycelium grows weakly, sparsely and loosely. 2：

Mycelial growth often occurs in mushroom and shiitake mushroom cultivation. After the mushroom is covered with soil, the fluffy mycelium grows continuously on the surface of the fine soil, and in severe cases, it forms a fungus skin, delaying the emergence of mushrooms or not setting mushrooms.

The common problems in the cultivation of edible fungi mainly include unreasonable ingredients. The sterilization of the bacterial bag is not complete. There is a problem with the quality of the culture. High temperature, high humidity. and pests and so on.

Different types of edible mushrooms have different requirements for substrates, for example, mushrooms like to use waste such as cow dung, straw, and wood chips as substrates, while shiitake mushrooms are suitable for using alkaline materials such as wheat straw, cottonseed husks, and corn cobs as substrates. Selecting a suitable substrate is the key to ensure the growth and reproduction of the strain. 2.

Pay attention to aseptic technique: the preparation of cultures needs to be aseptically processed to avoid contamination by other bacteria or fungi. Hygienic measures should be taken during operation, such as wearing gloves, masks and other protective equipment correctly, and using disinfectants to wash utensils and tools.

3.Temperature control: The growth of strains requires a certain temperature environment.

Different varieties of fungi have their own requirements for the temperature and humidity of the growing environment, so the internal temperature and humidity should be controlled during the growth process according to the characteristics of each fungus. 4.Oxygen**:

Edible mushrooms require a lot of oxygen to grow, so make sure that the air in the incubator is well ventilated to ensure adequate oxygen**. 5.Culture Quality:

The quality of the strain also has a great impact on the cultivation effect. High-quality strains can improve the growth rate and fecundity, and get a better harvest effect. Therefore, we need to choose a regular and professional strain manufacturer to obtain high-quality strains.

The above are the elements that need to be paid attention to in making edible mushroom cultivars.

Pure culture method, selective culture.

method and advantage cultivation method.

Edible fungi is a general term for fungi that can form large fruiting bodies and can be used for human consumption or medicine. There are more than 350 species of edible fungi known in China, and the above-mentioned fungi grow in different regions and different ecological environments. There are many species and quantities that grow in mountain forests, such as shiitake mushrooms, fungus, white fungus, monkey's head, pinemouth mushrooms, red mushrooms and porcini mushrooms.

In the fields, roadsides, grasslands and grass piles, there are straw mushrooms, mushrooms, etc. In the south, there are more high-temperature fruiting fungi; In alpine areas and cold areas in the north, low-temperature fruiting fungi grow more often.

There are many types and quantities of woody fungi growing in mountain forests, such as shiitake mushrooms, fungus, white fungus, lion's head, pinemouth mushrooms, red mushrooms and porcini mushrooms. In the field, roadside, grassland and grass pile on the dung, grass mushrooms, straw mushrooms, mushrooms, etc. In the south, there are more high-temperature fruiting fungi; In alpine areas and cold areas in the north, low-temperature fruiting fungi grow more often.

Brother, I have a V letter from a technician in the agricultural world here: Nongyef, and there is a Q Q group of thousands of people, and the dao in it are all farmers.

There are 5 commonly used methods for edible mushroom cultivation:

1 bag cultivation method. 2. Bed cultivation method.

3. Furrow planting method. 4 box cultivation method.

5. Potted cultivation method. Specific cultivation techniques can be found on the Internet.

Nutritional conditions: carbon source, BAI nitrogen source, inorganic DU

Salt, vitamins, growth cause zhizi dao

Environmental conditions: temperature (lower temperature in the fruiting body stage, higher temperature in the mycelium stage) moisture (the optimal moisture content of the culture material is 65%)

Humidity (optimal humidity is 75% in the mycelium growth stage and 90-95% in the fruiting body growth stage).

Light (no light is needed in the mycelium growth stage, and appropriate light supplementation in the fruiting body stage can induce fruiting body differentiation) air (the mycelium growth stage has low air requirements, and the fruiting body growth stage must have smoother air and can be ventilated).

pH (most edible fungi prefer an acidic environment for growth and development.
