Cultivation method of Pleurotus ostreatus wall covered with soil

The yield of Pleurotus ostreatus decreased sharply due to the consumption of water and nutrition. Using fully covered soil cultivation, not only the mushroom body is stained with a lot of soil, but also the mushroom is crisp and the price is low. By using the method of covering soil on the wall, Pleurotus ostreatus not only increases production, but also has good quality, and will not be stained with soil. The specific practices are as follows.

First, the manufacture of bacterial wall. After harvesting two or three tide mushrooms, use a knife to cut one end of the mushroom bag into a 10-centimeter-long bag, put it on the other end of the stick, and line up 2 sticks. One end of the film is placed on the outside, and the first layer between the two mushroom tubes is 30 centimeters apart, unlimited in length. Fill each row with crushed sticks or soil in the middle, pour enough water and then arrange the second layer. Draw in 3 to 5 centimeters in each row. It is arranged into a trapezoidal bacterial wall, which can be arranged in 5-7 layers. After the row, the top is covered with 3 to 4 centimeters of broken soil to wet the soil to make a small ditch. Insert a sorghum or corn stalk every 50 cm long to facilitate ventilation and downward water seepage.

Second, the management of bacterial wall. After the mushroom wall is made, pour a flood of water to make the whole mushroom wall soak through the water. Then cover with film for 1 week without watering. One week later, the film was removed, the ditch was watered, and the bacterial wall was watered once. After 3-5 days of primordium appearance, the whole mushroom stage should add water to the ditch according to the situation to keep the bacterial wall naturally moist.

Third, harvest. When the cap is basically unfolded and the mushroom color changes from dark to light, the spores have not yet ejected or there is a small amount of ejection, that is, medium well, it can be harvested. Early harvest will affect the yield, too late affect the quality and the growth of Pleurotus ostreatus. After each harvest, the mycorrhiza left on the mouth of the bag should be cleaned in time. At this time, the two ends of the mushroom stopped spraying water for 2-3 days and only added water to the ditch. One week later, water the mushroom thoroughly and wait for the arrival of Erchao mushroom. Generally, 3 gas and 4 tide mushrooms can be harvested.
