Causes of mycelium growth of Lentinus edodes and its control methods

Lentinus edodes is an important edible strain, which has strong edible and medicinal value. Lentinus edodes is cultivated in various areas of our country, but many people will have the phenomenon of excessive mycelium growth during cultivation, which affects the formation of fruiting body. So what is the reason for the growth of hyphae? How to prevent and cure it? Let's take a look at the detailed introduction of the pro-agricultural network.

1. The harm of mycelium overgrowth

The so-called excessive growth of mycelium means that the mycelium grows too vigorously in the culture substrate, which occurs not only in Lentinus edodes, but also a common physiological disease in many edible strains. Excessive growth of hyphae will consume and waste a lot of nutrients in culture materials, resulting in a lack of nutrient supply during mushroom production, thus affecting the formation of fruiting bodies. In addition, the mycelium skin is too thick, the respiration of mycelium is inhibited, and the growth of fruiting body is difficult, which leads to slow or no mushroom production.

2. The reason for the excessive growth of hyphae

There are many reasons for mycelial growth, most of which are related to the planting environment and cultivation substrate. If the shiitake mushroom cultivation room has too few windows or is built in a hidden environment, resulting in indoor darkness and less light, it may cause mycelium to grow too much. If too much water or nutrients such as cornmeal are added in the preparation of nutrients, the hyphae will also grow too much. The ventilation of the indoor environment and high air humidity will also lead to excessive mycelium growth, too light when lifting the covered film or too short time to lift the film, and so on.

3. Prevention and control of mycelial growth.

In the mycelium growth period and mushroom period must create a good environment to promote the formation and growth of fruiting bodies, when the hyphae begin to thicken white, and grow to 2cm or so, the mycelium growth is mostly uneven, then the film will be opened for one to several days to ventilate, until the cultivation bag around and do not stick hands, and then cover the film again.

On the second day, there is no need to lift or lift the film, let the water vapor in the culture material make the mycelium lodge and change color, if not lodging, strengthen ventilation, brush the mycelium with a tool to force lodging. Or spray very low concentration of lime water, dry and then cover the film, you can change color and lodge.

The above are the causes and control methods of the mycelium growth of Lentinus edodes brought by the pro-agricultural network.
