How to keep oyster mushroom substrate moist? Sharing practical tips

1. Moisture retention by casing soil over a wall of mushroom logs. Inside the shed, lay a soil ridge 15-20 cm thick along the length of the mushroom bags, take the bags that are fully colonized and about to fruit out of their plastic bags, and arrange them neatly on the soil ridge. For each layer placed, cover with soil 3-4 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; up to 6-9 layers can be placed, and the topmost layer must still be covered with soil and smoothed. After the wall is built, spray one heavy watering so the casing soil absorbs enough water. After that, spray water every day to keep the casing soil moist, and manage fruiting as usual. This method can increase oyster mushroom yield by 50%

After the wall is built, spray one heavy watering so the casing soil absorbs enough water. After that, spray water every day to keep the casing soil moist, and manage fruiting as usual. This method can increase oyster mushroom yield by 50%-90%.

2. Moisture retention by covering the bag mouths with nutrient soil. Nutrient soil formula: 45 kg of fertile soil, 5 kg of plant ash, add an appropriate amount of water and mix well; the amount of water added is appropriate when a handful of soil released from a height of 1 m falls apart on hitting the ground. When filling the bags, put 2-3 cm thick nutrient soil into each end of the bag. During the fruiting period, spray water on the nutrient soil 1-2 times a day, and manage the rest as usual. This method can increase yield by about 50%.

3. Moisture retention by casing soil in a sunny bed. After bag-cultivated oyster mushrooms finish one flush, remove the bags and sun-dry for 1-2 days so that a skin forms on the surface of the mushroom logs, to prevent invasion by pests and diseases and to inhibit excessive formation of fruiting bodies. Then use a sterilized kitchen knife to cut the surface lengthwise, and arrange them on the sunny bed with the cut side facing up. Fill the gaps with fine sand, then cover with fine soil 2-3 cm thick. Finally, irrigate with an aqueous solution containing calcium superphosphate, monopotassium phosphate and white sugar, in a ratio of 2:0.2:1:100, and then manage as usual. This method can increase yield by more than 80%.
