Non-pathogenic diseases of edible fungi

2. Non-pathogenic diseases

Inappropriate living conditions and improper cultivation and management measures or genetic variation will cause obstacles to the growth and development and physiological obstacles of edible fungi.

All kinds of abnormal phenomena. This disease is not caused by pathogenic microorganisms and insect pests, so it is also called non-infectious disease. The causes and symptoms are as follows:

(I)

Lentinus edodes, mushrooms, Pleurotus ostreatus can all occur is the phenomenon of overgrowth. Especially after the mushroom is covered with soil, the villi hyphae grow vigorously, and the fine soil surface produces "emergence".

"hyphae", the formation of hyphae overgrown, in serious cases dense agglomeration, forming a bacterial membrane, and delay the emergence of mushrooms, reducing the yield. Pleurotus ostreatus due to improper management, hyphae

In vain growth, a strong bacterial bundle network was formed on the surface of the culture material, but the fruiting body primordium was not formed, and the mushroom was delayed. The mycelial healing stage of Lentinus edodes cultivation materials, if

Due to improper management, a thick white bacterial membrane was formed on the surface of the culture material, which did not change color and could not form a fruiting body.

The excessive growth of mycelium may be caused by improper management, the mushroom room is less ventilated, and the plastic film covered by Pleurotus ostreatus, Lentinus edodes and cultivation materials is not covered for a long time.

Can ventilate, the carbon dioxide concentration is too high; the mushroom material covers the fine soil and the mushroom material block surface humidity is too high, and the Pleurotus ostreatus material layer is dry and so on.

All of them can cause hyphae to grow, which is not conducive to the formation of fruiting bodies.
