Anti-cold and anti-freezing technology of Lentinus edodes in Zhejiang Province caused by cold wave

It is during the mushroom emergence period, but affected by the strong cold wave, Zhejiang Province will usher in a severe freezing day of rain and snow on the 20th-25th. In order to avoid anoxia, decline in vitality and softening rotting sticks in the mycelium caused by abnormal weather, the majority of mushroom farmers should strengthen their management and do the following work well:

Snow disaster in mushroom shed

First, pre-rain and snow management:

1. Strengthen the heat preservation management of Lentinus edodes shed. The small arch shed can be buckled in the greenhouse, and the mulch such as film and straw curtain can be covered outside the shed to keep warm and dehumidify. Plastic film is used as an apron at the bottom of the shed to reduce the invasion of cold air at the bottom, plug the gap and minimize the heat dissipation of the gap, and reduce the number of times in and out of the mushroom room, so that the temperature inside the shed is 3m / m 5C higher than that of the outside world, which can basically ensure the activity of mycelium.

2. Stop spraying water and keep the material surface as dry as possible (at low temperature, the mycelium of Lentinus edodes goes into hibernation, such as spraying water is easy to die).

3. Remove the ice and snow accumulated on and around the roof in time to prevent the mushroom shed from collapsing.

4. Dig drainage ditches around the mushroom shed to keep the drainage smooth and avoid the attack of Rain Water and snow water on mushroom materials. Rush to harvest Lentinus edodes that can be harvested or are about to be harvested; do a good job of heat preservation and warming.

5. Check and reinforce the scaffolding to prevent the heavy snow from collapsing.

6. According to the snow situation, remove the mulch if necessary to reduce the pressure of the mushroom shed, prevent the mushroom shed from collapsing caused by freezing rain, and reduce the loss.

7. The mushroom shed of "human mushroom mixed residence" should do a good job of evacuating personnel before the coming of rain and snow to ensure the safety of mushroom farmers.

Second, disposal after rain and snow:

1. Remove snow, clear ditches and drain water

The main results are as follows: (1) for the edible fungi cultivated in the open field (Auricularia auricula, Lentinus edodes cultivated in semi-basement), the stagnant water in the field with melting ice and snow should be eliminated, the soaking time of the bacterial rod (bacterial bed) in the snow water should be reduced as much as possible, and the mycelium in the bacterial rod should be anoxic and its vitality decline. the rotting rod appeared to soften;

(2) for protected cultivation or factory cultivation, the ice and snow on and around the mushroom shed (house) should be removed in time to prevent the mushroom shed from collapsing. Dig drainage ditches around the mushroom shed to keep the drainage smooth and prevent Rain Water and snow water from attacking the mushroom material.

two。 Do a good job of ventilation. Keep the air fresh, reduce humidity and reduce diseases. In case of disease, timely isolation management or harmless treatment.

3. Wait for the temperature to rise steadily, clean the mushroom bed in time and remove the dead shiitake mushrooms. After the mycelium growth was restored, the daily management was restored.
