What causes mushrooms to turn yellow? Detailed explanation of prevention and control measures
What we commonly call the mushroom is a type of fungus, also known as the button mushroom or white mushroom. When mature, its exterior color is white-gray, but many farmers experience yellow mushrooms during cultivation, and in considerable numbers. Yellow mushrooms mean the mushrooms are no longer fresh. Although they do not affect edibility, they do have a certain effect on taste, also reduce economic value, and cause unnecessary losses. So what causes yellow mushrooms to appear? Let's take a look at the detailed introduction from Qinong Net.
1. Improper low-temperature management
During the mushroom cultivation period, if the humidity of the cultivation environment is high in the low-temperature season, or if too much water is sprayed, the mushrooms retain a large amount of water on their surface. After absorbing a large amount of water, it cannot evaporate in time in the low-temperature environment, which weakens the mushroom's metabolism, causes a large number of bacteria and microorganisms to invade, infects diseases, and leads to mushrooms turning yellow.
Prevention and control measures: Understand the temperature type and normal growth temperature of each variety, and manage them well. In addition, do not spray too much water; control the humidity of the cultivation room to maintain normal growth of the mushroom fruiting bodies. Also, spray various fungicides to kill or inhibit the growth of pathogens.
2. Continuous low-temperature climate
A continuous low-temperature climate makes the temperature of the cultivation room too low. When the temperature is too low, the mushroom fruiting bodies are in a state of poor growth, which triggers various diseases and causes the yellow mushroom phenomenon.
Prevention and control measures: When temperatures are low, find ways to raise the temperature of the cultivation room. Generally, it should be maintained above 15 degrees during the day. After discovering diseases caused by low temperature, promptly spray agents to sterilize, strengthen management, and prevent the yellow mushroom phenomenon from spreading.
3. Malnutrition
The mushroom growth cycle is relatively short, about one month per harvest. After 3-4 consecutive harvests, the nutrients in the fungus bag can no longer satisfy the normal growth of the mushrooms. After budding, because the fruiting bodies cannot obtain sufficient nutrients, they cannot grow normally, gradually turn yellow due to malnutrition, and eventually die.
Prevention and control measures: When it is found that the nutrients in the fungus bag can no longer satisfy the growth of the mushrooms, an appropriate amount of nutrient solution can be added to the fungus bag to ensure the smooth growth of this harvest. Once grown and mature, harvest them in time, then discard the fungus bags that no longer contain any nutrients, and start another batch of mushroom cultivation.
