What are the key points for spring management of oyster mushrooms? Key measures explained in one article
Oyster mushrooms are one of the common edible fungi and are widely cultivated. 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 still suffer from cold air invasions, so the first thing to do when cultivating oyster mushrooms in spring is to deal with temperature changes. The temperature of the mushroom shed and the bag temperature should be measured frequently. When the air temperature in the mushroom shed is higher than 20 degrees, cooling can be achieved by spraying water, adding covers during the day, and ventilating at night. If cold air arrives, attention should be paid to keeping warm: remove part of the straw curtains during the day to let direct sunlight increase the temperature, and close doors and windows tightly at night to reduce the temperature difference between day and night. When the mushroom shed is below 8 degrees, in order to allow the oyster mushrooms to grow and develop normally, measures such as making a fire or other heating methods should be taken, but attention should be paid to the carbon dioxide concentration.
2. Increase humidity reasonably
The fruiting temperature for spring oyster mushrooms is between 10-25 degrees, which is suitable for oyster mushroom growth. At this time, air humidity should be increased and kept at a relative humidity of about 85%, while direct sunlight should be reduced. This is to avoid a sudden rise in temperature in late spring that creates a high-temperature, high-humidity environment in the mushroom shed. Therefore, in daily management, spray 1-3 times per day according to temperature changes to maintain humidity, but spraying water also has a limit and should not be excessive. Keeping air humidity below 95% is sufficient.
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 lead to deformed mushrooms or diseased mushrooms. Therefore, heat preservation and ventilation should be reasonably coordinated to ensure the normal growth of the sown oyster mushrooms. Generally, ventilate more at high temperatures and 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 and prevention and control work should be strengthened, not giving pests and diseases any opportunity. The principle of prevention first and integrated control should be adopted. First is physical control: black light lamps can be used to trap and kill mushroom mosquitoes, mushroom flies, and similar pests. 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.
