Treatment of Water shortage of Culture material in the later stage of Pleurotus ostreatus

The output of the first stubble of Pleurotus ostreatus accounts for about 40% of the total output. Generally, after the second crop of mushrooms is harvested, due to the depletion of water in the culture material, it is rare to produce mushrooms again, the mushroom body is thin, the mushroom meat is loose and dry, and the taste is poor. In order to increase the yield, the following methods can be taken to replenish water and nutrient solution:

(1) vertical bag hole irrigation method: the immersion method requires a container to hold water, but some are inconvenient because the container is small or for other reasons, this method can be used. Put the mushroom bag upright on the floor of the mushroom room, pull up the edge of the plastic bag to store water after adding water, and then insert a hole with a diameter of 2 cm in the middle of the bag mouth, the hole is as deep as 4 centimeters thick, and pour water into the bag every day, hot and cold, and warm water in cold weather. Wait for the material bag to absorb enough moisture, and then palletize the mushrooms.

(2) broken planting and cultivation method: select good soil quality, near the water source, make the border in the east-west direction, 40 cm deep, 90 cm wide, unlimited length, 10-15 cm above the ground along the border, dig drainage ditches around the site, spray dichlorvos around the site, and disinfect with lime powder around and at the bottom. Remove the plastic bag from the bacterial tube and cut it into two sections, tie 6 holes with iron wire around the bacterial tube, and stand the cross section closely upward in the border. Plug it tightly with soil between the tube and the tube, cover it with 1 cm thick granular soil (after disinfection), pour water into the border once, and wait for the water to seep through, then cover the soil to keep the material surface 1 cm thick. Finally, cover the border with film to keep warm and moisturize, and the mushrooms can be produced after 7 days.

(3) Wall irrigation method: remove the plastic bag from the water-deficient bacterial tube and dig out the mushroom root and the infected part of miscellaneous bacteria. The bottom of the wall is covered with a layer of brick, take more fertile garden soil, require loose soil, according to 100 kg of soil plus 15 kg of wheat bran, 3 kg of lime, mix well and adjust moisture, and then put a layer of bacteria tube to add a layer of soil, the height of the bacterial wall is 1-1.5 meters. Then take the sticky soil as mud, spread all over the surface of the fungus wall, about 0.8 cm thick, thin is better, but there can be no loopholes. Finally, a water tank was built on the top of the wall. After 2 days, the water and wet soil were irrigated, the mycelia were basically filled with bacteria wall in 5 days, and the mushrooms were produced in 8 days.

You can also remove half of the plastic bag of the bacterial tube. When you build the wall, there are plastic bags facing outward, two bacterial tubes that take off half of the plastic bag facing inward, the top of the wall, leaving a 10 cm gap between the tops of the two bacterial tubes, and the gap is filled with fertilizer soil. The part of the bacterial tube where the bag is removed between the layers is also added with a layer of fertile soil (the outside of the plastic bag is not added with soil). The wall is 1-1.5 meters high. Finally, a concave flume was built at the top of the fungus wall, and wet soil was irrigated with water. The mushroom could be produced in 8 days with more mushrooms and good quality.

The above methods should be used according to the situation. If you want to make Pleurotus ostreatus more high-yielding, you can add nutrients to the water while irrigating. The formula of nutrients is: glucose 100g, magnesium sulfate 8g, urea 6g, calcium superphosphate 10g, potassium dihydrogen phosphate 6g, water 50kg.
