Management methods and techniques of Edible Fungi in Spring

The climatic characteristics of spring: the temperature rises quickly, but it is hot and cold and unstable. 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. according to this characteristic, the management should pay attention to the following points:

1. Temperature management

In 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 change 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 spray water to cool the ground in the shed. Take heat preservation measures on cloudy and rainy days or in cool weather.

2. Humidity management

After 2-3 times of mushroom bag in autumn and winter, the water contained in the bag consumes a lot and becomes lighter obviously, so it should be rehydrated in time. 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 in the shed low, so as to avoid the high temperature in the shed after water injection. causing bacterial bags to be contaminated by miscellaneous bacteria. The humidity in the shed can be adjusted by spraying water. when the weather is sunny and the temperature in the shed is high, you can spray more water to cool and moisturize the mushroom. at the same time, you can not spray water on the mushroom body. after spraying water, you must be ventilated, and the humidity in the shed should be kept at about 85%.

3. Ventilation management

After three times of mushroom harvest, 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, which can be combined with appropriate weather conditions and water spraying conditions for ventilation.

4. Light management

When the weather is clear, be sure to cover the cover of the roof at noon to avoid strong light and maintain an appropriate amount of scattered light.

5. 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. Remove weeds, garbage and discarded bacteria bags inside and outside the shed; spray fungicides and insect brakes regularly in and around the shed; all vents, doors and windows should be equipped with microporous nylon screen to prevent mosquitoes and flies from flying in. Once occurs, the use of pesticides should be cautious, the use of high-efficiency and low-toxic pesticides and should be sprayed toward the mushroom bag after picking mushrooms, must not be sprayed directly on the fruiting body.
