Mushrooms are common fungi and vegetables in our daily life. How to prevent mushroom death?

During the growth period of mushrooms, due to poor management or the bad external environment, some small mushroom buds on the mushroom bed often shrink, turn yellow and finally die. In severe cases, a batch of small mushrooms on the bed will die. The main causes of death are: lack of nutrients in the culture medium, high fruiting position and dense fruiting bodies on the soil surface; When picking mushrooms, careless operation will destroy the surrounding small mushrooms, affect the normal growth and development of small mushrooms, and lead to mushroom death. Due to the sudden temperature rise, the mushroom house lasted for several days (2 1? 25℃), the evaporation of water in mushroom bed is accelerated, the metabolism of mushroom body is accelerated, and the supply of water and nutrition is insufficient. Due to lack of nutrition and water, the small mushrooms withered and died.

Some small mushrooms died because of poor ventilation, high carbon dioxide concentration and lack of oxygen. Especially at high temperatures. Mushrooms are sensitive to water. If the covering soil layer fails to replenish water in time, or the mushroom water and high-quality water are sprayed too much, or the culture oozes water, water accumulates on the upper part of the material layer, resulting in mycelium death, insufficient nutrient supply and mushroom withering. The suitable pH value for mushroom mycelium growth is 6 ~ 8. At the fruiting stage, when the pH value of covering soil and watering is lower than 5, the mushroom buds die. Excessive use of pesticides will cause harm and a large number of mushrooms will die. If mushrooms turn red and brown after spraying, and no pathogenic bacteria are found, it is mostly caused by drug damage.

In order to prevent hyphae from growing on the soil surface, the position of mushrooms should be pressed down to avoid too dense mushrooms. In the later stage of spring mushroom, we should pay attention to the cooling of mushroom house to prevent high temperature invasion. Strengthening ventilation is an effective measure to reduce relative humidity, prevent carbon dioxide accumulation and avoid the breeding of miscellaneous bacteria.

In water resources management, we should pay attention to time, weather and water quality. Spray more on sunny days and less on rainy days; Spray more mushrooms and less mushrooms. Be careful, use hard water to grow mushrooms. To ensure water quality, pay attention to stubble water and manage it scientifically. Avoid spraying water. Strictly control pesticide concentration to avoid excessive pesticide.
