High-quality and High-yield cultivation techniques of Pleurotus ostreatus

1 Culture material formula: corncob or rice straw as the main material, plus 20% wheat bran, 5% corn flour, 2% lime, 1% gypsum, 1% sucrose, 65% water content in the material.

2 bagging and sterilization: use 17cm × 45cm × 0.04cm pressure-resistant polyethylene plastic bag, put the well-mixed material into the bag, loose and tight, and tie the two ends of the string tightly. Then put on the brick type atmospheric pressure aseptic stove to sterilize, when the temperature reaches 100℃, maintain a constant temperature of 8 ℃ for 10 hours, then turn off the engine, cool naturally, then take it out and place it in the receiving room.

3 inoculation culture: move the sterilized material bag into the inoculation room, which is required to be dry and clean, and the window is closed. Before vaccination, 10% limewater should be sprayed indoors to purify the air. After about 15 minutes, you can be vaccinated. The seeds were inoculated at both ends and sowed with the method of drilling holes, with two rows in each bag and 4 eyes in each row. After receiving the seeds, the bacteria bags were moved into the culture room for culture. Keep temperature 22 ℃ 25 min, about 25 days, the hyphae will fill the bag.

(4) mushroom production management: in order to increase the yield per unit area, the new soil mulching cultivation technique was adopted. The method is to take off the plastic bag full of bacteria, cut it into two sections, and arrange it vertically in the sunny border, which is 1 meter wide and 25Mel 30cm deep, unlimited in length. While taking off the bag, cover the soil at the same time, the thickness of the soil is 2 cm, should not be too thick. Build a bow-shaped bamboo sheet on the sunny border and cover it with plastic film to keep warm and moisturizing. About a week later, the mushroom can be budded, and the humidity in the air will be increased by 85% and 90%. The scattered light will be given, and the temperature will be kept at 16% 25 ℃. There is no need for temperature difference stimulation to produce a large number of mushrooms. When mushrooms reach medium well, they can be harvested.

The cultivation of Pleurotus ostreatus by this method has a wide range of raw materials, low cost, high economic benefits, and the average bioconversion rate is more than 180%.
