Management of bag planting Edible Fungi in plastic greenhouse in Spring

When spring comes, the temperature picks up quickly, but it is unstable. Mushroom farmers who use plastic greenhouse to cultivate edible mushrooms such as Pleurotus ostreatus and Lentinus edodes should, according to the unstable characteristics of climate change in spring, pay attention to the weather forecast every day, and adjust the cultivation and management measures at any time according to the weather changes.

1. Temperature management

In normal sunny weather, the temperature in the shed will be higher when the temperature is higher. In order to keep the temperature lower in the shed and make the quality of mushroom growth good in spring, the temperature and humidity will be changed from warming and moisturizing in winter to cooling and moisturizing. Specific measures: when the sun is strong during the day, such as 8-9 a.m. to 5 p.m., the roof is covered with grass curtains, roll up the grass curtains in the morning, evening or at night, and the ground in the shed is cooled by spraying water. Take heat preservation measures on cloudy and rainy days or in cool weather.

two。 Water management

After 2-3 tide mushroom bags in autumn and winter, the water in the bag consumes a large amount and becomes lighter obviously. There are many ways to replenish water in time. The simpler method is to inject water into the bag with a water injector. After water injection, the mycelium of the bacterial bag will grow again after absorbing water, which will exothermic and increase the temperature of the bag, and the temperature in the shed will become higher. Cooling measures such as rolling the curtain at night should be taken in time to keep the temperature low in the shed and avoid contamination of the bag by miscellaneous bacteria caused by high temperature after water injection.

3. Ventilation management

After the three-tide mushroom, a large amount of nutrients are consumed in the bag, the mushroom production is obviously reduced, and the amount of oxygen needed is relatively reduced. It can be ventilated once in the morning and evening, combined with water spraying, and there is no need to strengthen ventilation.

4. Pest control

As the temperature rises, pests begin to grow and reproduce, preventive measures should be taken in time to avoid the occurrence of insect pests, all vents, doors and windows should be equipped with microporous nylon screen to prevent mosquitoes and flies from flying in, once it occurs, pesticides should be used cautiously, and should be sprayed to the bacterial bag after mushroom picking, and must not be sprayed directly on the fruiting body.

5. Emergency measures in case of ice and snow disaster

1. Reinforce the support in time to prevent the roof from collapse

two。 If the part collapses, the bacterial bag can be transplanted to a safe place.

3. If the roof collapses, clean up the ruins, rearrange the bacterial bags and cover them with a cover. after the bad weather, re-build the shed, move into the bacterial bags, and continue to produce mushrooms.

4. If the disaster is serious, and the planting quantity is large, and it is difficult to repair, clear the shed thoroughly.
