The causes and control measures of the latest mushrooms and yellow mushrooms

The mushroom we call in daily life is a kind of fungus, also known as Agaricus bisporus, white mushroom, the appearance of which is white-gray after maturity, but many farmers appear the phenomenon of yellow mushroom when planting, and there are a lot of them. Yellow mushroom represents that the mushroom is no longer fresh, although it will not affect eating, but it still has a certain medicinal properties on the taste, but also reduces the economic value, resulting in unnecessary losses. So what is the reason for the emergence of yellow mushrooms? Let's take a look at the detailed introduction of the pro-agricultural network.

1. Improper management of low temperature

During the mushroom cultivation period, if the humidity of the culture environment is high in the low temperature season, or the amount of spraying water is large, the moisture attached to the mushroom is larger, and after absorbing a large amount of water, the mushroom can not evaporate in time in the low temperature environment. it will lead to the weakening of mushroom metabolism, causing a large number of bacteria and microorganisms to invade, infect diseases, and cause mushroom yellowing.

Prevention and control measures: understand the temperature type and normal growth temperature of each variety, do a good management, in addition, do not spray too much water, it is appropriate to control the humidity of the culture room, to maintain the normal growth of mushroom fruiting body, and to spray all kinds of fungicides to kill or inhibit the growth of bacteria.

2. Persistent low temperature climate

Continuous low temperature climate will make the temperature of the culture room too low, the mushroom fruiting body in a poor growth condition, resulting in a variety of diseases, the emergence of yellow mushroom phenomenon.

Prevention and control measures: at low temperature, we should find a way to raise the temperature of the culture room, which should be maintained at more than 15 degrees during the daytime. After discovering diseases caused by low temperature, we should spray fungicides in time to prevent the spread of yellow mushrooms.

3. Malnutrition

The growth cycle of mushroom is relatively short, and stubble can be harvested once a month. After 3-4 consecutive stubble harvesting, the nutrition in the bag can no longer meet the normal growth of mushroom. After budding, the fruiting body can not get enough nutrients, resulting in abnormal growth, gradually yellowing due to malnutrition, until death.

Prevention and control measures: when it is found that the nutrients in the bacterial bag can no longer meet the growth of the mushroom, an appropriate amount of nutrient solution can be added to the bacterial bag to ensure the smooth growth of this crop, wait for the growth to mature, harvest it in time, and then eliminate the bacterial bag without any nutrients. Restart another batch of mushroom culture.

The above are the reasons for the many mushrooms brought by the pro-agricultural network and the prevention and control measures. I hope it can help you. If you want to know more about mushroom cultivation, please pay attention to the pro-agricultural network.
