How to control the growth of miscellaneous bacteria of Auricularia auricula?

Auricularia auricula is a kind of edible fungus with high economic benefits, which is deeply loved by consumers, whether stir-fried or cold, but also rich in certain nutrients. In the cultivation process of Auricularia auricula, if it is not managed properly, it is easy to be contaminated by miscellaneous bacteria, which will lead to the reduction of yield and quality. Then how to control the growth of Auricularia auricula miscellaneous bacteria?

Generally speaking, the methods of controlling the growth of different miscellaneous bacteria are different. let's take a look at several common methods for the prevention and control of Auricularia auricula.

1. Green mold of Auricularia auricula

Green mold of Auricularia auricula may occur in any link of Auricularia auricula production, once it occurs, the production of Auricularia auricula will certainly be reduced. There are many opportunities for this pathogen to enter the bag, such as sawdust, corncob, wheat bran, etc., especially the weak fruiting bodies, which are easy to be infected.

Prevention and control methods: usually to keep the fungus shed around the clean, fungus cultivation sites must do a good job of ventilation, drainage work, so as to reduce the growth factors of miscellaneous bacteria. Spray lime water every three days after the fungus comes out of the ear. Try to use fresh culture materials, especially the link of sterilization should be strictly controlled. Don't break the bag when dealing with it, or the miscellaneous bacteria will come in immediately.

2. Black fungus rotten ear disease

Black fungus rotten ear disease, also known as Auricularia auricula, mainly shows that after the auricularia auricula is mature, the auricularia auricula piece becomes soft, and if serious, it will lead to the festering of the root of the fungus. The main reason for this disease is the occurrence of rotten fungus in a large area caused by high temperature, poor light, poor ventilation and high humidity due to untimely harvest. Of course, it may also be the reason for the bag material, such as the bag material is too wet, pH ups and downs may cause fungus rot.

Prevention and control methods: at ordinary times, it is necessary to strengthen the ventilation and light conditions of Auricularia auricula cultivation environment. Auricularia auricula should be harvested immediately after it is mature, so as to avoid the phenomenon of rotten ear. Once the rotten ear occurs, scrape off the rotten ear with a wooden knife and rinse it off with a certain concentration of quicklime. If the phenomenon of rotten ears in a large area should be treated with professional drugs, such as mushroom disease elixir.

3. Agaric cowhide hoop

This is a common disease of Auricularia auricula. The main manifestation is that the auricularia auricula is affixed to the fungus like a dog skin plaster. Cowhide hoop is a kind of miscellaneous bacteria that affects the yield of Auricularia auricula, once it occurs, the consequence is more serious. This kind of miscellaneous bacteria is more common in overcast, rainy and humid weather, and if the disease is serious, it will cause the bacteria to be attached to the whole fungus.

Prevention and control methods: strong light can not directly shine on the fungus, ear pile should pay attention to strengthen the daily management work, especially ventilation, watering, weeding and so on. After the heavy rain, it is necessary to drain the stains in the trench in time to avoid the phenomenon of stagnant water and rotten ears.
