High quality and prolific planting techniques of Pleurotus ostreatus in early spring

When the temperature in the greenhouse was lower than 8 ℃, the growth of Pleurotus ostreatus was slow, and the growth of Pleurotus ostreatus was inhibited when it was below 4 ℃. In order to ensure the normal growth and development of Pleurotus ostreatus, the temperature in the mushroom shed should be controlled at 10 ℃ ~ 20 ℃. Artificial fire or other heating measures should be taken, but the harmful substances such as carbon dioxide produced in the heating process must be discharged out of the mushroom shed.

The reasonable humidification spring mushroom temperature is 10 ℃ ~ 25 ℃, which is suitable for the growth of Pleurotus ostreatus, increase the relative humidity of ambient air by about 85%, reduce direct sunlight, and prevent the temperature from rising suddenly at the end of spring to form a mushroom environment with high temperature and high humidity. According to the change of air temperature, spray water one or three times a day to ensure the humidity in the mushroom shed. However, it is not suitable to spray too much water, and the air humidity in the mushroom shed should not exceed 95%.

Strengthening ventilation and heat preservation in the greenhouse contradicts each other. Pleurotus ostreatus can not grow at low temperature, and poor ventilation will lead to the increase of diseased and deformed mushrooms. The coordinated management of heat preservation and ventilation can ensure the normal growth of Pleurotus ostreatus. In general, there is more ventilation when the temperature is high, and less ventilation when the temperature is low.

Rational use of yield-increasing agents can increase production of Pleurotus ostreatus, and there are many kinds of yield-increasing agents, and there are also a variety of preparation methods. At present, there are many such commodities on the market, including powder and liquid, Zhuang Psilocybin, Zengmailing, Yuling and so on. They all have a good effect on increasing production, and they can be used with reference to the prescribed dosage of the commodity.

Replenish the moisture of the bacterial bag in time the culture material in the bacterial bag is continuously lost due to the direct exposure of both ends to the air during the mushroom emergence period. when the moisture in the material is lost by half, it will affect the normal mushroom production. Usually after two crops of mushrooms, the material surface appears the symptom of lack of water, resulting in dryness and cracks, and it is not easy to form mushroom buds. At this time, we should pay attention to timely replenishment of water, to prevent the lack of water and do not produce mushrooms, or less mushrooms, poor quality. At present, the commonly used water replenishment methods in production are immersion replenishment method and pressure water replenishment method. The soaking replenishment method is to pour the prepared nutrient solution into a pool or a specially made water container, and the bacteria bag uses iron strips to make several holes in a triangle on the material surface. Pay attention to the iron bar to penetrate the culture material so that the material can absorb enough water. Generally soak for 5 to 8 hours, so that the weight of the bacterial bag after absorbing water reaches about 90% of the original weight. Pressure rehydration method. A special replenishing needle for Pleurotus ostreatus is generally used to connect with the agricultural sprayer. One end of the needle is in the shape of an injection needle, and the other end is connected to the effluent skin tube of the sprayer. The needle is inserted into the culture material and pressurizes the pressure rod of the sprayer. In this way, the nutrition contained in the sprayer will be injected into the bacterial bag of Pleurotus ostreatus under certain pressure, playing the role of replenishing water and nutrition. Generally, about 3 holes need to be inserted in each bag. Replenish water to 90% of the weight of the raw material. When there are conditions, equipped with water pumps to increase water pressure, you can use multi-head water replenishment device to speed up the efficiency of water supply.

Pick mushrooms in time. Pleurotus ostreatus grows vigorously in this period. When a white fluffy substance appears at the place where the cap is connected to the stalk, the mushroom should be picked in advance. If the harvest is too late, the tissue of Pleurotus ostreatus is aging, the resistance is reduced, it is easy to break and rot, and the quality is reduced.
