Efficient Spring Cultivation Techniques and Management Key Points for Oyster Mushrooms
Oyster mushroom is one of the common edible fungi and is cultivated by many people. 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 during spring cultivation? Let's take a detailed look below.
1. Prevent Sudden Temperature Changes
Spring temperatures gradually rise, but in early spring oyster mushrooms are still affected by cold air, so the first thing to do when cultivating oyster mushrooms in spring is to deal with temperature changes, and the temperature of the mushroom shed and the bag temperature should be measured frequently. When the air temperature in the mushroom shed is above 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, removing part of the straw curtains during the day to let direct sunlight increase the temperature, and keeping 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 attention should be paid 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 the relative humidity at about 85%, while reducing direct sunlight. This is to avoid a sudden rise in temperature in late spring that causes the mushroom shed to form a high-temperature and high-humidity environment, so in daily management, spraying should be done 1-3 times a day according to temperature changes to maintain humidity, but there is also a limit to water spraying, and too much is not suitable; keeping air humidity below 95% is sufficient.
3. Strengthen Ventilation
Ventilation and heat preservation are in a mutually contradictory relationship. Under low-temperature conditions, oyster mushrooms cannot grow normally, 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 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 temperature in spring 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. The principle of giving priority to prevention and comprehensive control should be adopted. First is physical control, which can use black light lamps to trap and kill mushroom mosquitoes, mushroom flies, and the like; chemical control can also be used. After harvesting mushrooms, spray dichlorvos on the ground and walls of the mushroom shed to kill insects and sterilize.
