More and more fungus crops have become an indispensable food on the dining table. Pleurotus ostreatus is a common fungus food in life. It is not only delicious, but also rich in minerals and complete in amino acids, which can be compared with milk, lean meat and fish, even worse. Then, this paper introduces the steps of nutrient preparation, growth management, timely harvesting and disease prevention.

First, nutrient preparation

Wood chips, rice straw, bagasse, corn stalk, peanut hull, bean stalk powder and other raw materials can be used to cultivate Pleurotus ostreatus, but in order to obtain high-yield and high-quality Pleurotus ostreatus, appropriate amount of auxiliary materials such as bran and calcium superphosphate need to be added.

Second, growth management

Pleurotus ostreatus needs to adjust the temperature, keep moisture and prevent the pollution of miscellaneous bacteria during the fungus growing period. Two days after sowing, the strains will start to germinate and gradually grow around. At this time, it is necessary to check the temperature change in the culture material several times a day. Pay attention to control the room temperature below 30℃ and the air humidity around 65%. In order to prevent the pollution of miscellaneous bacteria, the room temperature should be controlled below 10 after sowing.

Third, timely harvesting

The harvesting period of Pleurotus ostreatus is when the color of the mushroom cap changes from deep to light, and there is white velvet in the concave part. At this time, the Pleurotus ostreatus is thick, with high yield and delicious taste. After harvesting, it is necessary to clean up the mushroom surface in time, remove the dead mushrooms and rotten mushrooms in time, and recuperate the mycelium for a period of time, and the next batch of mushrooms can grow, which can generally be taken for 3-4 times.

Fourth, disease control

The common disease of Pleurotus ostreatus is brown spot, which will endanger its normal growth. It is necessary to reduce the temperature, and the ward can spray 2% formaldehyde solution or1:500 times carbendazim for prevention and control.
