Measures against cold and freezing of edible fungi in winter

First, harvest a batch of mushrooms that can be harvested as soon as possible to avoid the direct impact of the cold wave on the yield.

Second, strengthen the heat preservation measures of mushroom shed

The plastic film can be used as an apron at the bottom of the shed to reduce the cold air attack at the bottom of the shed, plug the gap and minimize the heat dissipation of the crevice, and to form a windproof barrier with crop straw to the north of the greenhouse to prevent the wind and cold; reduce the number of times in and out of the mushroom room. In this way, the temperature in the mushroom shed (room) is higher than that of the outside world by 3mi 5 ℃, which can basically maintain the activity of the mycelium. If there is no mushroom shed, please take measures as soon as possible, set up the shed and buckle the film in time to keep warm.

Stop spraying and injecting water immediately.

Try to keep the noodles and sticks dry. Because the mycelia of edible fungi go into hibernation when they are dried at low temperature, spraying water at low temperature is easy to cause the decrease of mycelium activity.

Fourth, clear the ice and snow and open ditches for drainage.

Remove the ice and snow accumulated on and around the mushroom shed (house) in time to prevent the mushroom house from collapsing. Open a drainage ditch around the mushroom shed (room) to keep the drainage smooth and avoid the attack of Rain Water and snow water on the mushroom material.

Fifth, after the temperature picks up steadily, strengthen the management.

(1) the following management measures should be taken for soil-covered cultivation such as Agaricus bisporus:

1. Make up the soil with loose material and clean up the dead mushrooms. When the temperature rises steadily to 10 ℃, loosen the material and replenish the soil in time. This not only helps to eliminate the waste gas from the culture material, but also helps to promote the fracture of old mycelium, promote the growth of new mycelium, form a strong mycelium, and lay a foundation for improving the yield of spring mushroom.

2. Topdressing fertilizer and replenishing water. After the continuous emergence of mushrooms in last autumn, the nutrition loss was serious and the PH value decreased a lot. After the beginning of spring, it is necessary to fertilize and replenish water in time in order to achieve high yield.

(2) the following management measures should be taken for bag cultivation such as Auricularia auricula and Lentinus edodes:

After the temperature rises, timely ventilation, timely spray and injection of water to the material surface, moisture management adopts dry-wet management methods to promote the mycelium to turn tide and produce mushrooms.
