Prevention and Control of Death of Young Straw Mushrooms

When cultivating straw mushrooms, you may encounter various pests and diseases. So today I will tell you about the prevention and control of the death of young straw mushrooms:

1. The culture medium is acidic:

Straw mushrooms prefer alkaline environments. When the pH is less than 6, they can produce mushrooms, but it is difficult for them to grow. Acidic environments are more suitable for the growth of fungi such as green mold and yellow mold, which compete for nutrients and cause the death of straw mushrooms. Therefore, when preparing the culture medium, the pH value in the medium should be appropriately increased. After picking the first batch of mushrooms, you can spray 1% lime water or 5% wood ash water to keep the pH value of the medium at around pH 8.

2. The material temperature is low or the temperature changes suddenly:

The growth of straw mushrooms is very sensitive to temperature. Generally, when the material temperature is lower than 28 degrees Celsius, the growth of straw mushrooms will be affected or even die. If the temperature changes too much, such as when a cold wave or typhoon hits, the temperature will drop sharply, causing the death of young mushrooms, and in severe cases, the death of adult mushrooms.

3. Improper water management:

Straw mushrooms have certain requirements for water temperature, generally requiring the water temperature to be about the same as room temperature. For example, spraying deep well water at about 20℃ in the hot summer will cause a large number of young mushrooms to die. Therefore, spraying water should be done in the morning and evening, and the water temperature should be around 30℃.

According to the different stages of the growth and development of the fruiting bodies of the straw mushroom, the water spraying method should be mastered correctly. If the fruiting body is too small, spraying too much water will cause the young mushrooms to die. In the fruiting body needle stage and small button stage, the material surface must be sprayed with water. If the material surface is dry, it can only be sprayed in the aisle of the cultivation room and water can be poured on the ground to increase the relative humidity of the air.

4. Mushroom picking damage:

The mycelium of straw mushrooms is relatively sparse and very easy to be damaged. If the action is too big when picking, it will touch the surrounding culture medium, causing the mycelium to break. The mycelium of the surrounding young mushrooms will break and the water and nutrition will not be supplied. Therefore, the action should be as gentle as possible when picking mushrooms. When picking straw mushrooms, press the growth base of the straw mushroom with one hand to protect other young mushrooms, and use the other hand to twist and pick up the mature mushrooms. If there are densely clustered mushrooms, they can be picked together to avoid the death of most immature mushrooms due to the collision of individual mushrooms.
