What to Do When Straw Mushroom Mycelium Shrinks? Causes and Control Methods
1. Using inferior spawn: Spawn that is too old or too young, degenerated spawn, weak mycelial vitality, poor stress resistance, or spawn stored for a long time in environments with temperatures that are too low or too high can all lead to failure to germinate after spawning and shrinkage of mycelium in the spawn blocks. Control: Select spawn of the appropriate age and high quality, and ensure the temperature during the cultivation process does not get too low. 2. Improper control of compost temperature: When the air temperature is high, the compost is too thick, and the mushroom house has good insulation, the temperature inside the compost after spawning exceeds 42°C for an extended period, which causes mycelium to shrink and die, resulting in burning of the mycelium.

Causes of Deformed Mushrooms in Agaricus bisporus and Their Prevention and Control Methods
1. Deformed mushrooms. When ventilation is poor and the carbon dioxide content in the mushroom house exceeds 0.3%, deformed mushrooms are likely to appear. If the fruiting position is too deep, mushrooms growing between the cracks of the coarse soil also tend to be deformed. The key to prevention and control is to pay attention to ventilation and air exchange in the mushroom house. 2. Red root mushrooms. Slightly acidic cultivation material, a high-temperature stage before fruiting, excessive water content in the casing soil layer, excessive application of glucose as a supplemental fertilizer, and poor ventilation in the mushroom house can all easily lead to red root mushrooms. The pH of the compost should be properly adjusted, the water content of the casing soil should be maintained at 22%-25%, watering should be avoided during high temperatures, and the concentration of supplemental fertilizer should be appropriate.

Analysis of the Causes of Abundant Yellow Mushrooms and Prevention and Control Methods
The main causes are improper management during the low-temperature season. During the low-temperature season, the humidity inside the mushroom shed may be too high, with excessive watering, and too much free water adhering to the mushroom bodies. After absorbing water, it cannot evaporate, which weakens the metabolism of the mushroom bodies, causing various pathogens to take advantage of the opportunity, multiply in large numbers, and trigger various diseases of the fruiting bodies; continuous low-temperature weather causes the temperature inside the mushroom shed to be too low, and the edible fungus fruiting bodies remain in a poor living environment for a long time, leading to disease; some edible fungus varieties are at the 3rd to 4th flush during the fruiting period, and the nutrient supply in the fungus bags is insufficient. After budding, the
