The latest course of planting techniques and methods of Pleurotus ostreatus

Pleurotus ostreatus is one of the common edible strains, its fleshy flesh is thick, the flesh is white and strong, it is native to Europe and North America, we began artificial cultivation in the 17th century, and now it is widely cultivated in the world. So how to grow Pleurotus ostreatus? Let's take a look at the detailed introduction.

1. Fermentation of culture material

2000 kg of rice straw, 1500 kg of livestock manure, 15 kg of urea, 20 kg of bean cake, 50 kg of superphosphate, 50 kg of gypsum powder and 30 kg of lime can be used as culture materials. Next, it is necessary to do a good job in the fermentation of culture materials. Choose an area with sufficient water source, convenient drainage and irrigation, and close to the mushroom shed. Before building the pile, pre-wet the straw for 3-5 days to fully soften its water absorption, and then build the pile. The scale of the pile depends on the actual situation. Spread a layer of straw on the bottom, sprinkle with lime, calcium superphosphate, urea, etc., one layer of grass and one layer of dung, so as to fill seven layers. In the construction of the pile, the 1-3 layers do not need to be watered, and then each layer should be watered once, with less watering in the lower layer and more watering in the upper layer. It is necessary to turn the heap in time after the pile is built to ferment it. Each time, the material of the lower layer is turned to the upper layer, the four sides turn to the middle, and the middle one turns around, so as to promote its fermentation evenly. Turn the pile for the first time after 6 days, and then turn the pile every 2-3 days until the fermentation is completed, and then move into the mushroom room after disinfection.

2. Disinfection of mushroom house

Pleurotus ostreatus does not need light during cultivation, after setting up the mushroom bed during cultivation, clean the mushroom room, first spray the ground with dichlorvos, about 1 gram per square meter, and then sprinkle lime powder on the ground, generally 1-2 grams per square meter. After disinfecting the mushroom room, spread the culture material on the bed surface, requiring the material surface to be neat and uniform in thickness. when the temperature of the culture material is lower than 25 degrees, gently pat it flat and tighten it, and the operator should undergo disinfection.

3. Sowing seeds

Sowing can adopt the methods of sowing, mixed sowing and stratified sowing. Sowing takes the bacteria out of the strain bottle and puts it into a container to stir evenly. One bottle of bacteria per square meter is suitable for wheat seed, and it can be evenly scattered on the material surface. After sowing, you can spread a layer of culture material and flatten it. After sowing, the temperature of the shed should be kept between 22 and 28 degrees, and the humidity should be between 60% and 70%. It is not suitable for ventilation within 2 days after sowing, a small amount of ventilation can be allowed on the third day, and the hyphae begin to grow in a week, then the ventilation rate can be increased.

4. Soil covering and disinfection

After 15-20 days of sowing, when the hyphae and growth reached 2/3, the soil could be covered with lime and phosphate fertilizer, then disinfected with dichlorvos and then covered with soil. After covering the soil for a week, spray continuously for 2-3 days, 1-2 times a day, pay attention to the soil moisture should not stick to the hands, which can promote the rapid formation of fruiting bodies.

The above is the introduction of the planting technology of Pleurotus ostreatus. I hope it can help you. If you want to know more about it, please follow us.
