What Is The Main Reason For Shiitake Mushrooms Sticks To Rot?

1. Proper Proportion of Base Materials
The proportion of raw materials used in mushroom cultivation is crucial. Each material must be mixed in a scientifically balanced ratio, correcting the misconception that "more is better." For trace elements, it’s important to follow the principle of "less is more." Exceeding the recommended amount of certain materials, such as lime, superphosphate, gypsum, or urea, can cause detrimental effects like stick rot. Additionally, excessive moisture, uneven mixing of materials, or high-temperature sterilization shortly after mixing can increase acidity and alter pH levels, contributing to stick rot.

2. Poor Ventilation During Cultivation
Inadequate ventilation during the cultivation process can lead to insufficient oxygen levels and a buildup of carbon dioxide, which weakens mycelial activity. This may result in the phenomenon of "bacterial reversion," where the mycelium weakens or retreats, inhibiting its development and causing stick rot. Proper ventilation is essential to maintain healthy mycelium growth and prevent such issues.

3.High Temperatures During Mycelium Development
Excessive heat, especially during the puncturing or ventilation of the substrate, can cause sudden temperature spikes in the piles. This often leads to the phenomenon known as "burning bacteria," where the mycelium shrinks or even dies due to thermal stress. Consistent temperature control during the mycelium development stage is critical to avoid such damage.

4. Improper Shading and Sun Exposure
Improper shading in the mushroom cultivation area can expose the mushroom bags to direct sunlight, leading to the damage of the mycelium. Ultraviolet rays can burn the mycelium on the sticks, causing localized yellowing, leakage of red water, and even ulceration or infection. Ensuring proper shading is vital for maintaining healthy mushroom growth.

5. Excessive Watering or High Water Temperature
Over-watering the mushroom sticks or using water that is too hot can cause problems, especially in hot and humid weather. If not managed properly, these conditions can result in stick rot. Moreover, when mushroom sticks fail to produce mushrooms after being watered, the stagnant moisture within the sticks can also contribute to rotting. Careful water management is crucial to prevent these issues.

6. Improper Mushroom Picking and Root Management
Failing to clean the mushroom roots promptly or using incorrect picking techniques can cause physical damage to the mushroom sticks. Large pieces of mushroom material left on the sticks can create wounds, which, when watered, may lead to mold growth and stick rot. Proper handling during the picking process and root cleaning is essential to avoid such contamination and ensure healthy mushroom cultivation.
