Last Updated: 2024/11/05, In the process of Pleurotus ostreatus production, because the management measures are not in place and the environmental conditions are not suitable, deformed mushrooms are often formed. The reasons for the formation of abnormal mushrooms should be found out and effective control measures should be taken in production. 1. The stalk of spherical or flask-shaped Pleurotus ostreatus is spherical or flask-shaped, the surface is uneven or twisted in the shape of waves, the cap can not be formed, only a small point or obvious ice-like stripes. This is caused by virus infection, the application of virus K, virus A, carbendazim spray or smear prevention and treatment. two。 The seed of cauliflower-shaped Pleurotus ostreatus

In the production process of Pleurotus ostreatus, abnormal mushroom is easy to form due to inadequate management measures and inappropriate environmental conditions. In the production, we should find out the causes of abnormal mushroom formation and take effective control measures.

1. The stipe of spherical or flasks mushroom is spherical or flasks, the surface is uneven or twisted and wavy, the cap can not be formed, only a small point or obvious icicle stripes. This is caused by viral infection, the application of virus K, virus A, disinfectant spray or smear control.

2. The fruiting body primordium of broccoli mushroom is enlarged continuously, and the stalk is strongly branched, forming a hemisphere like cauliflower. This is due to the high concentration of carbon dioxide in the cultivation environment and the saturation of air humidity. Ventilation should be strengthened to reduce carbon dioxide concentration and air humidity.

3. Coral-shaped mushroom stipe is not long thick or does not form a cap, but continues to repeat the division, resulting in coral-like, white color. This is due to high carbon dioxide concentration and weak light, should strengthen ventilation, improve lighting conditions.

4. Sprout-shaped Pleurotus ostreatus stem slender, cap very small or no cap. This is due to the low temperature and long duration of cap formation. Therefore, during the formation period of the cap, if the temperature is about 0℃, try to warm up and keep warm.

5. The stipe of Pleurotus ostreatus is thick and long, edematous, and the cap is abnormal, small or without cap. This is due to the high temperature, strong light and high carbon dioxide concentration in the differentiation stage of Pleurotus ostreatus fruit body, which disturbed the metabolism of substances and caused crazy growth. Ventilation should be used to cool down and improve lighting conditions.

6. Mushroom body shriveled and withered Pleurotus ostreatus grew emaciated, fruiting body was yellow-white or light brown, mushroom body withered from top to bottom. This is due to lack of water or low air humidity in the culture medium, and it should be replenished in time.

7. After the formation of flat cut primordium of irregular shape Pleurotus ostreatus, it did not differentiate into stipe and cap, but grew into irregular fungus block, and the cap twisted and cracked at the later stage and exposed the flesh. This is due to excessive amounts of pesticides such as dichlorvos and metocide, which should be used less or not.
