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

Causes and Control Methods of Deformed Mushrooms in Greenhouses
1. Hollow white-stem mushrooms. The mushroom stems become loose and white, and in severe cases shrink to form a hollow center. Causes: during the fruiting body growth stage, it is caused by dry air and high temperatures. When the relative air humidity is below 85%, the water content of the casing soil layer is relatively low, and the temperature inside the mushroom house is above 18°C, the mushrooms grow quickly and evaporate water quickly, causing the water absorbed by the mushroom body to be less than the water lost through transpiration. Control methods: spray water promptly during the day to keep the relative air humidity at 90%, and ventilate promptly after spraying water in the morning and evening to lower the greenhouse temperature, keeping it at 14-

What to Do When Oyster Mushroom Pinheads Die? Cause Analysis and Control Methods
In oyster mushroom production, due to unsuitable mushroom house environmental conditions and compost, as well as improper management or severe weather and other reasons, pinheads on the mushroom bed often shrink, turn yellow, and eventually die; sometimes pinheads on the bed surface die in batches, seriously affecting yield and economic benefits. For this, the author conducted extensive observational research and summarized the causes of mushroom death and control methods, presented as follows: 1 Continuous high temperatures In autumn mushroom production in northern regions, temperatures go from high to low, which is suitable for the growth and development of oyster mushroom fruiting bodies

Cause Analysis and Diagnosis and Treatment Methods for Mycelial Regression in Oyster Mushrooms
In the autumn and winter seasons of last year, mycelial regression occurred frequently in oyster mushroom production, and there were also sporadic cases this spring and summer. The symptoms of mycelial regression are as follows: the spawn blocks germinate normally, the colonization of the substrate is slower than normal, and growth from the spawn blocks is radial. When the mycelium length reaches 4-5 cm, the mycelium gradually becomes sparser starting from the spawn block, while the mycelium at the growing tips is denser and denser white and continues to develop, with the mycelium behind it fading and thinning accordingly, until finally the surface of the entire mushroom bag appears slightly grayish-white or even devoid of mycelium. At 40 days after inoculation, the mushroom bags appear grayish-white rather than the normal pure white, and no

What to Do When the Surface of Oyster Mushroom Substrate Turns Black? Cause Analysis and Control Methods
The main causes of blackening on the substrate surface and the control methods are: (1) Oyster mushroom mycelium soaked in water for a long time causes rot and blackening. In this case, the condensation water on the substrate surface should be absorbed and dried promptly. If it is grown on beds, excess water at the bottom should also be absorbed and dried promptly. (2) Contamination by foreign microorganisms and breeding of insect pests cause blackening. When blackening occurs, pests must be controlled or the affected part dug out promptly to prevent it from spreading.
