How to prevent and treat spots on enoki mushrooms? A few practical methods to teach you

Mushrooms are an indispensable ingredient in our daily life, and among them, enoki mushrooms are deeply loved by consumers for their delicious flavor and smooth texture. Enoki mushrooms are also rich in many nutrients, and eating them regularly is good for the human body. Everyone knows that when it comes to cultivating mushrooms, the environmental requirements are very high, and their growing conditions must be met. So what are the growing condition requirements for enoki mushrooms? When spots appear,how should they be prevented and treated?

I. Growing conditions for enoki mushrooms

1. Temperature requirements

Enoki mushroom is a low-temperature solid fungus, so its mycelium can grow normally within the range of 5-30°C, but it is generally required to grow better under the condition of 22-25°C. If the temperature is too high, the mycelium will stop growing or die. If the temperature is too low, enoki mushrooms will show small caps, thin and elongated stalks, and excessive spindly growth.

2. Nutrients

As a saprophytic fungus, the enoki mushroom can only rely on its mycelium to absorb ready-made culture materials. In the specific planting process, choosing materials is very critical and will directly affect the quality and yield of enoki mushrooms. The nutrients needed for the growth of mycelium and fruiting bodies include vitamins, minerals, sugar nutrients, and so on.

3. Moisture requirements

During the mycelial growth period of enoki mushrooms, if the water content of the culture material exceeds 70%, the oxygen content will decrease, directly affecting mycelial growth. Therefore, during the period when the fruiting body primordia form, attention should be paid to air humidity.

4. Fresh air

During the growth process of enoki mushrooms, they need to continuously absorb fresh air to grow better. Especially during the formation period of the fruiting bodies, a lot of oxygen is consumed. If there is too much carbon dioxide in the air, it will negatively affect the growth of the fruiting bodies.

5. Light conditions

The mycelium and fruiting bodies of enoki mushrooms can grow in the absence of light, but if there is no light at all, deformed enoki mushrooms are very likely to appear. A little scattered light is best, as this can stimulate the growth of the caps, while too much light is not conducive to the growth of the enoki mushroom stalks. Therefore, we should keep a small amount of light coming into the mushroom house, and it cannot be completely dark.

II. How to treat spots on enoki mushrooms?

During the cultivation process of enoki mushrooms, spots often appear, generally due to attacks by diseases, commonly including black spot disease and rust spot disease.

If an enoki mushroom contracts black spot disease, it will first show on its caps. At this time, brown or dark brown oval spots will be seen. At first they are as small as a needle tip, and as time goes on, they will slowly become larger, with very neat edges. Sometimes cracks will appear on the caps.

To prevent black spot disease, the temperature and humidity in the mushroom house must be well controlled. When water needs to be sprinkled in the mushroom house, water must never be sprayed onto the fruiting bodies of the enoki mushrooms, especially not cold water. The humidity in the mushroom house must not be greater than 90 percent, and watering should be done according to changes in the weather. After each watering is completed, attention should be paid to ventilation. Once diseased enoki mushrooms are found, they should be removed in time.

If an enoki mushroom contracts rust spot disease, it generally infects the caps of the enoki mushrooms, on which spots the size of sesame seeds with irregular edges will appear. The preventive work is also similar to preventing black spot disease.
