What Causes Many Yellow Mushrooms? 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 the phenomenon of yellow mushrooms during cultivation, and in considerable numbers. Yellow mushrooms mean the mushrooms are no longer fresh. Although they do not affect edibility, they still have a certain medicinal effect on taste and also reduce economic value, causing unnecessary losses. So what are the causes of yellow mushrooms appearing? Let's take a look at the detailed introduction from Qinnong Web.
1. Improper low-temperature management
During the mushroom cultivation period, if the humidity of the cultivation environment is relatively high during the low-temperature season, or if the amount of water sprayed is large, the water adhering to the mushrooms will be relatively great. After absorbing a large amount of water, it cannot evaporate in time in the low-temperature environment, which will weaken the mushroom's metabolism, cause a large amount of bacteria and microorganisms to invade, infect diseases, and cause the mushrooms to turn yellow.
Prevention and control measures: Understand the temperature type and normal growth temperature of each variety, manage them well, and in addition, do not spray too much water. Control the humidity of the cultivation room and keep it suitable for the normal growth of the mushroom fruiting bodies. In addition, spray various fungicides to kill or inhibit the growth of pathogens.
2. Continuous low-temperature climate
A continuous low-temperature climate will make the temperature of the cultivation room too low. When the temperature is too low, the mushroom fruiting bodies are in a poor growth condition, thereby triggering multiple diseases and causing 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 for one harvest flush. After 3-4 consecutive harvest flushes, the nutrients in the mushroom 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 and gradually turn yellow due to malnutrition until they die.
Prevention and control measures: When discovering that the nutrients in the mushroom bag can no longer satisfy the growth of the mushrooms, an appropriate amount of nutrient solution can be added to the mushroom bag to ensure the smooth growth of this flush. After the mushrooms mature, harvest them in time, then eliminate the mushroom bags with no nutrients left, and start another batch of mushroom cultivation anew.
