Introduction to the causes of excessive growth of mushroom mycelium and the key points of control techniques

The excessive growth of mushroom hyphae is a common phenomenon in mushroom cultivation, that is to say, mushroom hyphae consume a lot of nutrients in the culture medium, so the fruiting body can not keep up with the nutrition and can not form fruiting body, which is very harmful to the growth of mushroom. Next, let's take a look at the reasons for the excessive growth of mushroom hyphae and the main points of control techniques.

First, the reason for the excessive growth of mushroom mycelium

Mycelium overgrowth is a common phenomenon in mushroom growth, which occurs for many reasons, most of which are due to the influence of planting environment and substrate.

If the mushroom room has fewer windows or chooses a more secluded place to build, the indoor light will be relatively dark, so the hyphae may grow too much. In the configuration of nutrients when adding a lot of water, or adding too much nutrients, similar to cornmeal, the hyphae will grow too much. If the indoor environment is too humid and unventilated, the phenomenon of excessive growth of hyphae is the most common. If the action of lifting the covered film is too light or the time is too short, the hyphae will grow too much.

Why can't mycelia grow well? It is thought that the excessive growth of hyphae will lead to the problem of wasting and consuming most of the nutrients of culture materials, the natural lack of nutrition during mushroom production, and the formation of fruiting bodies will also be affected. If the mycelium skin is too thick, it will inhibit the respiration of the mycelium, resulting in the growth of the fruiting body is more difficult, resulting in a long time or no mushroom phenomenon, growers will have a great loss.

2. Key points of prevention and control of mushroom mycelium overgrowth.

In the mushroom emergence period, the growth and development of the fruiting body is very important, so it is necessary to create a growth environment in which it can develop. If the mycelium of the mushroom has reached two centimeters, the color has turned thick white and the hyphae does not grow evenly, you can lift the film to breathe for a few days and cover the film until the planting bag and the surrounding area are no longer sticky. The next day, you don't need to lift the film and let the soda on it make the mycelium lodge until it changes color. If you don't fall down, you can lift the film again to breathe.

Third, the reason why mushrooms do not produce mushrooms.

The main results are as follows: 1. The carbon and nitrogen in mushroom ingredients are not suitable, it is very likely that the lack of carbon and too much nitrogen lead to the excess nutrition of mushrooms and the phenomenon of excessive growth of hyphae. In this way, the emergence of mushrooms will be delayed.

2. After the mycelium is full, if the humidity in the air is relatively low and the temperature is relatively high, the mouth of the bag can be opened early, and a relatively dry bacterial membrane appears on the pond surface, so that the buds can not be differentiated. If you encounter a similar situation, you can make a hole on both sides of the bacterial bag, remove the dry bacterial film, soak it in water, wait until it is full of water, and then put it on the shelf for ventilation and light, which will accelerate the emergence of mushrooms.
