How to Keep Oyster Mushrooms Moisturized? Learn These Three Techniques

Mushroom Cultivation 0 views
At present, growing oyster mushrooms in rural areas is fairly common, but yields are not high, mainly because after harvesting oyster mushrooms the water content of the substrate is low. But at this point the oyster mushroom mycelium has already spread throughout the entire substrate, making it very difficult to replenish water. How to keep the substrate moisturized and produce more mushrooms has become an important factor in whether oyster mushrooms can achieve high yields. There are three techniques: 1. Wall-style soil covering of mushroom logs for moisture retention. In the shed, lay a ridge of soil 15 to 20 cm thick along the length of the mushroom bags, and remove the plastic bags from the mushroom bags that have fully colonized and are about to fruit (these are called mushroom bags). Arrange the mushroom logs neatly

At present, growing oyster mushrooms in rural areas is fairly common, but yields are not high, mainly because after harvesting oyster mushrooms the water content of the substrate is low. But at this point the oyster mushroom mycelium has already spread throughout the entire substrate, making it very difficult to replenish water. How to keep the substrate moisturized and produce more mushrooms has become an important factor in whether oyster mushrooms can achieve high yields. There are three techniques:

1. Wall-style soil covering of mushroom logs for moisture retention. In the shed, lay a ridge of soil 15 to 20 cm thick along the length of the mushroom bags, and remove the plastic bags from the mushroom bags that have fully colonized and are about to fruit (these are called mushroom bags). Arrange the mushroom logs neatly on the soil ridge. Cover each layer with soil 3 to 4 cm thick, spray water on both sides of the soil and smooth it with mud. Then arrange the second layer of mushroom logs and cover with soil; 6 to 9 layers can be arranged, and the topmost layer must still be covered with soil and smoothed. After the wall is finished, spray heavily once so the covering soil absorbs enough water. After that, spray water every day to keep the covering soil moist, and manage fruiting according to conventional methods. This method can increase oyster mushroom yields by 50% to 90%.

2. Covering the bag openings with nutrient soil for moisture retention. The nutrient soil formula is: fertile soil 45 kg, plant ash 5 kg; the amount of water added is appropriate when a handful of soil taken at a height of 1 m and released falls to the ground and breaks apart. Bagging, cultivation and management are the same as conventional methods, except that nutrient soil 2 to 3 cm thick is placed in each of the two ends of the bag. During the fruiting period, spray water on the nutrient soil 1 to 2 times a day, and carry out other management as usual. This method can increase yields by about 50%.

3. Soil covering on raised beds for moisture retention. After bag-cultivated oyster mushrooms finish a flush, remove the bags and sun-dry for 1 to 2 days so that a skin forms on the surface of the mushroom logs, to prevent invasion by diseases and pests and to inhibit excessive formation of fruiting bodies. Cut vertically with a sterilized kitchen knife, and arrange them with the cut surface facing up on the raised bed. Fill the gaps with fine sand, then cover with fine soil 2 to 3 cm thick. Finally, irrigate with an aqueous solution containing superphosphate, monopotassium phosphate and white sugar, in a ratio of 2:0.2:1:100, and manage according to conventional methods. This method can increase yields by more than 80%.
