The latest course of planting techniques and methods of Pleurotus ostreatus in greenhouse

Pleurotus ostreatus is a species of Pleurotus genus of Pleurotus family, also known as Pleurotus ostreatus, Beifeng mushroom, Pleurotus ostreatus, etc. It is a widely cultivated edible fungus, rich in nutrients, containing 20~23 grams of protein per 100 grams of products, with extremely high cultivation value. Let's take a look at the cultivation technology of Pleurotus ostreatus in greenhouse together!

Greenhouse construction

Pleurotus ostreatus cultivation greenhouse east-west direction, leeward sunny, shed width 5 meters, length 30 meters, depth 0.5 meters (from the ground), surrounded by brick base or mound into a south low north high wall, south wall height 1 meter, north wall height 1.5 meters (from the ground). A 40×40 cm vent hole shall be reserved every 3 meters (one for each north and south/wall), the roof of the shed shall be firmly supported with bamboo poles, covered with plastic film, and straw curtain shall be added at the top. 3~5 days before feeding, fill enough water in the shed, sprinkle a layer of lime after water infiltration, and the dosage is 1 kg/m2.

Select a good seed

Pleurotus ostreatus can be cultivated all year round. The most suitable temperature for low temperature varieties is between 13~17℃, such as frozen bacteria, P2~2, etc., and the most suitable temperature range for medium temperature varieties is between 20~24℃, such as P.

Cultivation material allocation

The new cottonseed hulls of the same year can be stored for 24 hours after mixing, and can be bagged on the second day. The old cottonseed hulls of the next year can be fermented for 4~6 days after mixing to eliminate the breeding miscellaneous bacteria. When stacking fermentation, the material pile should be perforated and ventilated, and the pile should be turned over at least twice during the fermentation period. The longest fermentation time should not exceed 1 week. The ratio of material to water should be strictly controlled in mixing materials. Too wet mixing materials is not conducive to fermentation and growth of bacteria. Nitrogen and nutrients should be added according to proportion, and bacteria should be added to sterilize and prevent insects. When bagging, the amount of bacteria should not be less than 20%, so as to ensure that the bacteria can be produced quickly and the bacteria bag will not be contaminated by miscellaneous bacteria.

Hair management

The culture materials are bagged and put into the shed to grow bacteria. In autumn planting, all the bacteria bags are placed on the ground and only one layer is stacked. In spring planting, the bacteria bags can be stacked in 2 layers or 2~3 layers in a cross shape. In winter planting, the bacteria bags are stacked every 4 layers into a stack, and the two stacks are put together to promote the mycelium growth at both ends of the bacteria bag. When autumn planting, the shed film will be rolled up, and the greenhouse will be covered with straw curtains to avoid the greenhouse heating due to the closed shed. In winter planting, put down the film to keep warm, and open several grass curtains during the day to raise the temperature of the shed. Spring planting can be rolled up in front of the shed film to ventilate and cool down. In particular, pay attention to the temperature in the bag during the bacteria development period. If it exceeds 30℃, immediately ventilate and cool down or pour the stack to dissipate heat. Once high temperature burning bacteria occurs, the place where green mold grows in the bacteria bag can be dug out and filled with plant ash. If green mold has formed spores, plant ash can be mixed with 20% lime water to fill the contaminated part.

fruiting management

After pleurotus ostreatus hyphae grow full of bags, they can be stacked on the ridge in the shed to produce mushrooms. In autumn planting, the stacking height is 2~4 layers, 2~3 sorghum stalks or wooden sticks should be placed between each layer, ventilation holes on the back wall should be opened, straw curtains should be pulled up for ventilation in the morning and evening, and water spray should be used for cooling at noon. During winter planting, the stacks can be stacked into 8 layers. Spray water when it is hot at noon, and roll up the shed film in front of 1~1.5 meters for ventilation. Generally, the ventilation time is between 10~20 minutes. After ventilation, put down the shed film and straw curtain in time. In the morning, part of the straw curtain can be raised to warm up. When planting in spring, stack 4~8 layers, roll up the front film 1 meter high, and cover the grass curtain to the ground or the same height as the film depending on the temperature. Spray water 1~2 times a day to keep the relative humidity in the shed at about 85%, or water in the furrow to keep the surrounding of the stack moist. Spring planting and autumn planting to roll up the shed film, put down the straw curtain to avoid stuffy shed, pay attention to the temperature of bacteria stick. A tide mushroom should be cut off for 3 days after harvest, and then sprayed with water to produce mushrooms after the formation of primordium. In general, the first 2 tidal mushrooms can form 70~80% of the yield. In order to connect the stubble and improve the efficiency, it is appropriate to cultivate Pleurotus ostreatus with 2~3 tidal mushrooms in the greenhouse.
