Physiological Diseases of Mushroom and its Control

Mushroom is more sensitive to the environment, poor cultivation environment, will hinder its normal growth and development, resulting in a variety of abnormal phenomena, resulting in the reduction of mushroom yield and quality. The common physiological diseases of mushroom are mycelium growing, hard umbrella opening, thin skin opening early or Pleurotus ostreatus, empty root Pleurotus ostreatus and so on. The introduction is as follows:

Overgrowth of hyphae

Symptoms: after the mushroom bed is covered with soil and transferred water, the mushroom villi hyphae will continue to grow to the fine soil surface, and in serious cases, a fine, impervious quilt will be formed, thus delaying the mushroom production and reducing the mushroom yield.

The cause: it is mainly due to the light and fast water transfer in the soil layer, the mushroom room temperature exceeding 22 degrees Celsius, humidity exceeding 90%, and poor ventilation.

Preventive measures: 1, try not to use aerial mycelium growth is too exuberant, too dense bacteria. 2. After covering the soil, the water transfer of the soil layer should not be too urgent, and the water spraying should be carried out when the weather is cool in the morning and evening. At the same time, the ventilation of the mushroom room should be increased and the air relative humidity should be reduced. 3. It is necessary to re-cover the soil immediately and spray more water appropriately to promote the mycelium to form a fruiting body in time, or gently rake the covered soil surface before the mushroom bud is formed, increase ventilation and reduce relative humidity.
