Causes and prevention methods of deformity of hericium Erinaceus

Hericium Erinaceus is a kind of high-grade edible fungus with nutritional value and health care value. with the higher and higher living standards of people, the demand for it is also increasing, and more and more people grow it. But in the cultivation of hericium Erinaceus, it is found that hericium Erinaceus is abnormal, which makes people have a headache. what is the cause of this? Let's take a look at the detailed introduction with the editor.

1. Bald mushroom without thorn

The reason for this deformity is that the temperature is too high and the humidity is on the low side. Generally, at a temperature of about 25 degrees, the fruiting body does not form a cycle because of excessive evaporation but low humidity or moisture. So it leads to the formation of bald mushrooms without bristles.

Prevention and control methods: when the temperature is higher than 25 degrees, it is necessary to connect the film or open the window in time to strengthen ventilation and reduce the temperature, while timely irrigation or spraying water mist to increase humidity, keep humidity above 90%, and cover the roof in time to reduce sunlight exposure and reduce water evaporation.

2. Coral cluster mushroom

Coral cluster-shaped hericium Erinaceus is generally clustered with multiple branches at the base, like a pile of corals. If you look closely at the mushroom body, it will be obvious that a rhizomatous fungal cord is connected to the culture medium. Many of the fruiting bodies in this condition have already grown at the fruiting stage, and some of them can continue to grow, and the top will swell at the time of growth, forming multiple fruiting bodies like hericium Erinaceus. The main reason for this state of deformed mushroom is that the concentration of carbon dioxide is too high, which stimulates the stalk differentiation, thus inhibiting the growth and development of the central part.

Prevention and control methods: to strengthen ventilation and reduce the concentration of carbon dioxide in the air, especially in the stage of fruiting body formation and growth, the fruiting body that has formed coral clusters should be scraped off together with the surface culture material in time, and then cultured to make it produce mushrooms normally.

3. Abnormal mushroom color

This kind of deformed mushroom generally has yellow surface color, short and thick spines, and some fruiting bodies turn red and pink after maturity, with a bitter smell. The main reason for the formation of this kind of mushroom is that the temperature is too low. When cultivated in autumn and winter, due to the sudden drop in temperature, the temperature of the fruiting body is lower than 10 degrees, which will cause the mushroom body to turn red, and the color will become darker as the temperature drops. In addition, when cultivated indoors, when the fruiting body is stimulated by retention wind because of ventilation, it will also lead to the yellowing of the mushroom body.

Prevention and control methods: caused by low temperature, it should be taken into account in cultivation, arrange an appropriate time for vaccination to avoid the low temperature period. When cultivated in the field, it should be sealed with film, ventilated during the day and sealed at night; when cultivated indoors, the vents should not be opened too wide to avoid blowing directly to the direct current wind.

The above is the introduction of the causes and prevention methods of hericium Erinaceus deformity. I hope it can help you. If you want to know more about it, please follow us.
