The causes and Control methods of the latest abnormal Pleurotus ostreatus

Pleurotus ostreatus is one of the edible fungi that we often eat in our daily life, and it sells very well in the market, so it attracts many people to plant it, but the management of planting it is very important. Many growers often have the phenomenon of mushroom when planting, which gives people a headache. So what is the reason for the deformity of Pleurotus ostreatus? How to prevent and cure? Let's take a look at the detailed introduction.

1. Pleurotus ostreatus

It shows that the cap of Pleurotus ostreatus is small, and when the stalk is longer, it is named Pleurotus ostreatus. The reason is that during the period of primordium formation and differentiation, the concentration of carbon dioxide in the mushroom room is too high, resulting in hypoxia, and it will appear when the light is insufficient or too high.

Prevention and control methods: to strengthen ventilation, reduce the concentration of carbon dioxide in the air, but also adjust the light and temperature, especially the temperature, Pleurotus ostreatus has different requirements for temperature in each growth stage.

2. Pleurotus ostreatus

In this case, the abnormal mushrooms are characterized by granular protuberances on the edges and stiff caps. In severe cases, the cap differentiation is poor and irregular mushrooms are formed. The reason is that the temperature in the development period of mushroom body is too low and lasts for a long time, which leads to the imbalance of cell growth of mushroom body, so it forms Pleurotus ostreatus.

Prevention and control methods: to adjust the temperature, to keep the temperature of Pleurotus ostreatus room at the lowest limit of Pleurotus ostreatus growth, and there is a certain temperature difference between day and night, so as to promote the growth and development of mushroom body.

3. Cauliflower mushroom

As the name suggests, this malformed mushroom is branched and looks like a cauliflower, which occurs because it is sprayed with high concentrations of pesticides during the mushroom production period, or there are other toxic gases in the mushroom house, such as high carbon dioxide concentrations. Cauliflower mushrooms may appear.

Prevention and control methods: pay attention to the concentration when using any medicament, not too high.

4. Atrophic mushroom

It is normal in the early stage of mushroom development, but yellowing, edema or dry shrinkage will appear during the expansion period, and then stop growing, and it is best for the mushroom body to become soft and rot gradually. Edema is caused by excessive humidity or too much water sprayed on the mushroom body, causing the young mushrooms to absorb too much water, affecting normal breathing and metabolism. Dry shrinkage and edema on the contrary, it is because the air humidity is small, ventilation is too strong, resulting in the mushroom body lack of water and death.

Control methods: when selecting excellent varieties for cultivation, we must pay attention to the regulation and control of air humidity, which should not be too high or too low.

The above is the introduction of the causes and prevention methods of Pleurotus ostreatus, hope to help you, want to know more related knowledge, please pay attention to us.
