The latest course on winter management techniques of Pleurotus ostreatus

Pleurotus ostreatus is a kind of mushroom, which tastes very good and has rich nutritional value. The market demand in our country is also very large, and when cultivating Pleurotus ostreatus, we should adjust the management method according to the change of season. Especially in winter, the temperature is very low, which is very disadvantageous to the growth of Pleurotus ostreatus. So how to manage Pleurotus ostreatus in winter? Let's take a look at the management technology of Pleurotus ostreatus in winter with Xiaobian.

1. Clean up the material surface

The harvest time of Pleurotus ostreatus is usually in autumn every year. After the harvest of Pleurotus ostreatus in autumn, the first thing we should do is to clean up the bed of Pleurotus ostreatus. The main thing is to clean up the dead mushrooms, old mushrooms and some withered and yellowed old hyphae on the bed. Because there will be a lot of miscellaneous bacteria on these things, if they are not cleaned up in time, then the miscellaneous bacteria will cause great harm to the growth of Pleurotus ostreatus in the spring of the following year, affecting the yield and quality, so we must pay more attention to it.

2. Timely ventilation

After the autumn mushroom has been moisturized for about two months, the humidity of the mushroom room will be relatively high. In particular, the water content of culture materials and cover soil is also very high. Therefore, after cleaning the noodles, we should immediately open the doors and windows of the mushroom room and ventilate the mushroom room. Then punch a number of holes in the material surface to promote the discharge of water and waste gas. So that the mycelium can resume growth as soon as possible, while maintaining indoor air quality. Usually ventilation for about two hours at noon every day, if the temperature is low, then the ventilation should be stopped and the indoor temperature should be kept at about 3-4 degrees.

3. Proper fertilization

In winter, we also need to fertilize the mushroom bed properly to supplement the nutrients needed for its growth. Fertilizers can be mixed with substances such as livestock manure and superphosphate. Then boil it and spray it into the mushroom bed after cooling. And the PH value of the soil in the mushroom bed should be kept at about 7-7.5. The mycelium exposed to the bed should be covered with fine soil. Then we should also pay attention to do a good job of loosening the soil and removing the roots. For the mushroom bed with good mycelium growth, the ventilation should be improved. Remove the old mycorrhiza and dead mushrooms, do not hurt the mycelium, and then flatten the soil.

4. Water management

In winter, although the temperature is relatively low, the climate is relatively dry. Therefore, we also need to spray an appropriate amount of water on the bed to maintain the humidity in the mushroom bed. When spraying water, can be combined with spraying some micro-fertilizer, but also pay attention to the amount of water spraying. Not too much, if too much, the soil humidity is high, easy to freeze, affecting the growth of Pleurotus ostreatus. Then, after handling, close all the doors and windows, and if you encounter frost and snow, you should also pay attention to covering the grass outside the doors and windows.

The above is a brief introduction to the winter management technology of Pleurotus ostreatus. That's all for today's introduction. This article is for reference only. I hope it can help you all.
