The latest management points of Pleurotus ostreatus in spring

Pleurotus ostreatus is one of the common edible fungi, and there are many cultivators. With the gradual rise of temperature in spring, the instability of temperature and the aggravation of diseases and insect pests seriously affect the yield and quality of Pleurotus ostreatus. So how to manage the cultivation of Pleurotus ostreatus in spring? Let's take a look at the detailed introduction.

1. Prevent sudden changes in temperature

The temperature rises gradually in spring, but Pleurotus ostreatus will still be attacked by cold air in early spring, so the first thing to do in spring is the change of air temperature, and the temperature of mushroom shed and bag should be measured frequently. When the temperature in the mushroom shed is higher than 20 pairs, the temperature can be cooled by spraying water, covering the mulch during the day and ventilating at night; in case of cold air, pay attention to heat preservation, remove some grass curtains during the day, increase the temperature in direct sunlight, close doors and windows at night, and reduce the temperature difference between day and night. When the mushroom shed is less than 8 degrees, in order to make the normal growth and development of Pleurotus ostreatus, fire or other heating measures should be taken, but pay attention to the concentration of carbon dioxide.

2. Reasonable humidification

The spring temperature of Pleurotus ostreatus is between 10 and 25 degrees, which is suitable for the growth of Pleurotus ostreatus. At this time, it is necessary to increase the air humidity, keep it at about 85% relative humidity, and reduce direct sunlight. In order to avoid a sudden rise in temperature at the end of spring, the mushroom shed will form a high-temperature and humid environment, so it is necessary to spray 1-3 times a day according to the change of air temperature to maintain humidity, but there is also a limit for spraying water, which should not be too much, and the air humidity should be kept below 95%.

3. Strengthen ventilation

Ventilation and heat preservation are contradictory to each other. Pleurotus ostreatus can not grow normally in low temperature environment, but poor ventilation will form deformed or diseased mushrooms. Therefore, it is necessary to reasonably coordinate heat preservation and ventilation, sow the normal growth of Pleurotus ostreatus, generally more ventilation at high temperature, and less ventilation at low temperature to achieve balance.

4. prevention and control of diseases and insect pests

The temperature rise in spring is also a period of high incidence of diseases and insect pests, so we should attach great importance to it, strengthen prevention and control work, do not give opportunities to diseases and insect pests, and adopt the principle of giving priority to prevention and comprehensive control. First of all, physical control, black light can be used to trap and kill mushroom mosquitoes, mushroom flies, etc., or chemical control can be used. After mushroom picking, dichlorvos is sprayed on the floor and walls of the mushroom shed to kill insects and sterilize.
