A Complete Analysis of the Latest Key Points for Spring Management of Oyster Mushrooms

Oyster mushroom is one of the common edible fungi, and many people cultivate it. As spring temperatures gradually rise, unstable temperatures and worsening pests and diseases seriously affect the yield and quality of oyster mushrooms. So how should oyster mushrooms be managed when cultivated in spring? Let's take a look at the detailed introduction.

1. Prevent sudden temperature changes

Spring temperatures gradually rise, but in early spring oyster mushrooms will still be hit by cold air, so the first thing to do when cultivating oyster mushrooms in spring is to deal with temperature changes, frequently measuring the temperature of the mushroom shed and the bag temperature. When the air temperature in the mushroom shed is higher than 20 degrees, you can cool it by spraying water, add covers during the day, and ventilate at night; when cold air arrives, pay attention to keeping warm, remove part of the straw curtains during the day to let direct sunlight raise the temperature, and keep doors and windows tightly closed at night to reduce the temperature difference between day and night. When the mushroom shed is below 8 degrees, in order for the oyster mushrooms to grow and develop normally, measures such as lighting a fire or other heating methods should be taken, but pay attention to the carbon dioxide concentration.

2. Increase humidity reasonably

The fruiting temperature of oyster mushrooms in spring is between 10-25 degrees, which is suitable for oyster mushroom growth. At this time, air humidity should be increased to keep relative humidity at about 85%, while reducing direct sunlight. This is to avoid a sudden rise in temperature in late spring that creates a high-temperature, high-humidity environment in the mushroom shed, so in daily management, spray 1-3 times a day according to temperature changes to maintain humidity, but there is also a limit to spraying water; it should not be excessive, and keeping air humidity below 95% is enough.

3. Strengthen ventilation

Ventilation and heat preservation are in conflict with each other. Oyster mushrooms cannot grow normally in a low-temperature environment, but poor ventilation will also produce deformed mushrooms or diseased mushrooms. Therefore, heat preservation and ventilation should be reasonably coordinated to ensure the normal growth of sown oyster mushrooms. Generally, ventilate more at high temperatures and ventilate less at low temperatures, achieving a balance.

4. Prevent and control pests and diseases

The rise in spring temperatures is also a period of high incidence of pests and diseases, so great attention should be paid, prevention and control work should be strengthened, and no opportunity should be given to pests and diseases, following the principle of prevention first and integrated control. First is physical control: black light lamps can be used to trap and kill mushroom mosquitoes, mushroom flies, and so on. Chemical control can also be used: after harvesting mushrooms, spray dichlorvos on the floor and walls of the mushroom shed to kill insects and sterilize.
