High-yield cultivation techniques of Pleurotus ostreatus

Pleurotus ostreatus, a wild variety domesticated in recent years, has not formed large-scale production so far, and occasionally has a small amount on the market.

Base material preparation basic formula: cottonseed shell 250 kg, calcium superphosphate 5 kg, gypsum powder 4 kg, urea 1 kg, edible fungus three-dimensional nutrient essence (mixing bag) 1 bag. Points for attention: according to the technical level, the water content of the base material should be increased as much as possible, and the temperature of the mushroom shed should be kept at 20 ℃ ~ 25 ℃ after sowing.

The mushroom shed treatment was sprayed twice to eliminate all diseases without a trace, with an interval of 2 days, according to the dosage of one bag for every 20 square meters, carpet spraying was carried out to kill miscellaneous bacteria and pathogens. During the period of high temperature, insecticides can be applied together. Points for attention: after spraying, seal the mushroom shed, remove the mulch and other mulch, through the sun shed to maximize the efficacy of the agent under high temperature.

Bagging sowing is generally sown in August, when the temperature is higher, such as a higher level of cultivation technology and better conditions in the mushroom shed, the raw material cultivation can be adopted, and the formula is the same as above; if you feel unsure, you can adopt fermentation material cultivation, adding 3 kilograms of lime powder to the above formula, and then evenly spray the three-dimensional nutrient essence of edible fungi with water after the completion of fermentation, stir evenly and sow seeds in bags.

The management of pathogenic bacteria can be carried out according to Pleurotus ostreatus. After completing the germization, continue to send bacteria in the post-ripening stage. In the low temperature season, measures such as cooling and ventilation should be taken when the temperature is high, pay attention to avoid light strictly and accept as little stimulation from external conditions as possible, so that the mycelium can continue to grow nutritionally. Generally, about 15 days, the biological energy in the bacteria bag can reach the maximum accumulation, which lays a good foundation for mushroom production. According to the conditions of mushroom shed and cultivation environment, 800-1000 times liquid was sprayed every 3-7 days. To spray to the wall, ground, vents, etc., try not to spray bacterial bags directly.

The temperature of mushroom production management is generally higher in autumn, which can meet the temperature requirements of fruiting bodies, and there is no need for manual regulation. The relative air humidity should be kept at 85% to 95%. It is necessary to maintain good ventilation to reduce the concentration of carbon dioxide in the mushroom shed to 0.05%. Measures such as uncovering the grass or turning on the lights were taken to keep the light intensity in the mushroom shed about 500 lux.
