Causes and control methods of mycelium atrophy of mushroom

The cultivation method of mushroom is not difficult, but every step must be strict. Once there are omissions, it is easy to appear miscellaneous bacteria, diseases and even mycelium shrinkage, which is "fatal" for mushrooms. It will also affect the harvest of growers, so let's take a look at the causes and prevention methods of mushroom mycelium shrinkage.

1. Excessive temperature leads to mycelium burning.

In the process of mushroom cultivation, the temperature is too high, the culture material is relatively thick, and the material temperature is not stable and decreased after fermentation, all of which will lead to mycelium shrinkage.

Prevention and control methods: mushroom planting period should be staggered high temperature period, material temperature had better be controlled below 25 degrees Celsius. Once it is found that the mycelium shrinks caused by high temperature, it is necessary to turn the pile and ventilate immediately, and then re-adjust the humidity of the culture material and sow again.

2. the ammonia in the culture material leads to the atrophy of mycelium.

Many people add too much nitrogen fertilizer when building the pile, or add nitrogen fertilizer later, which will lead to the presence of ammonia in the culture material, leading to mycelium shrinkage.

Prevention and control methods: when planting mushrooms, add an appropriate amount of chemical fertilizer urea to avoid the emergence of ammonia in the later stage. If ammonia has been found in the culture material, open the window in time to ventilate, and use formaldehyde solution to turn over the material, wait until there is no smell of ammonia, sow again.

3. The culture material is too dry.

If the culture material is too dry, it will also lead to the filth of the hyphae, coupled with the very dry climate, the growth of food is very slow after the mycelium germinates.

Prevention and control method: you can cover a layer of wet straw on the side of the material, which can be soaked in lime water. In this way, the mycelium can sprout and eat again. If you encounter relatively dry weather when sowing, you can close the doors and windows after three days.

4. The quality of mushroom strain is not up to standard.

When the strain is bought, it is heated, and the vitality of the mycelium is reduced. It is also possible that the purchased strains are not planted in time, resulting in the aging of the strains, the natural growth is relatively slow, the growth is relatively weak.

Control methods: strain selection is very important, try to choose suitable culture materials to cultivate bacteria, the best is a variety with good germination ability and strong hyphae. When buying bacteria, try not to choose when the temperature is relatively high, and do not choose aging strains.

5. Too much moisture in the culture material.

Too much water in the culture material, and then cover the soil when encountered high-temperature weather, or high-temperature weather watering too much water without timely ventilation, will lead to mycelium lack of foreign gas, the phenomenon of shrinkage.

Prevention and control methods: in the stacking of materials to control moisture, not too high nor too low. If the moisture content in the culture material is too high when turning the pile, it should be flattened and dried immediately. In the later stage, remember not to spray water too heavily, pay attention to ventilation, so that the hyphae can resume growth.
