How to Manage Edible Mushrooms in Spring? Detailed Methods and Techniques

Climate characteristics of spring: temperatures rise quickly, but alternate between cold and hot, and are unstable. Based on the unstable climate changes in spring, pay attention to the weather forecast every day, and adjust cultivation management measures at any time according to weather changes. Based on these characteristics, management should pay attention to the following points:

1. Temperature management

On clear days, when the air temperature is relatively high, the temperature inside the shed will be even higher. To maintain a relatively low temperature inside the shed so that spring mushrooms grow with good quality, change from warming and moisturizing in winter to cooling and moisturizing. Specific measures: when sunlight is strong during the day, such as from about 8-9 am to about 5 pm, cover the top of the shed with straw curtains; in the early morning, evening, or at night, roll up the straw curtains, and spray water on the ground inside the shed to lower the temperature. On rainy days or when the weather turns cooler, take insulation measures.

2. Humidity management

After 2-3 flushes of mushrooms are produced in autumn and winter, the water contained in the mushroom bags is greatly consumed, and they become noticeably lighter, so water should be replenished in time. After water injection, the mycelium in the mushroom bags absorbs water and resumes growth, which releases heat and raises the bag temperature, and the temperature inside the shed rises accordingly. Cooling measures such as rolling up the curtains at night should be taken in time to maintain a relatively low temperature inside the shed, avoiding contamination of the mushroom bags by weed molds caused by high temperature inside the shed after water injection. The humidity inside the shed can be adjusted by spraying water. When the weather is clear and the shed temperature is high, more water can be sprayed to cool and moisturize. At the same time, note that water must not be sprayed onto the mushroom bodies. After spraying water, ventilation must be carried out. The humidity inside the shed should be maintained at about 85%.

3. Ventilation management

After harvesting three flushes of mushrooms, the nutrients in the bags are greatly consumed, mushroom production decreases noticeably, and the amount of oxygen needed is relatively reduced, so ventilation can be carried out according to appropriate weather conditions and watering conditions.

4. Light management

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

5. Pest and disease control

As the temperature rises, pests begin to grow and reproduce, so preventive measures should be taken in time to avoid pest outbreaks. Clear weeds, garbage, discarded mushroom bags, and so on inside and around the shed; regularly spray fungicides and insecticides inside the shed and around it; install microporous nylon gauze on all vents, doors, and windows to prevent mosquitoes and flies from flying in. Once an outbreak occurs, be cautious when using pesticides. Use high-efficiency, low-toxicity pesticides, and after harvesting mushrooms, spray toward the mushroom bags. Never spray directly onto the fruiting bodies.
