How to keep oyster mushrooms moist? Mushroom growers, remember these three tricks

At present, the main reason for the low yield of oyster mushrooms grown in rural areas is that the water content of the growing substrate is too low after harvesting. How to keep the substrate moist and produce more mushrooms has become an important factor in whether oyster mushrooms can achieve high yields.

Moisture retention by covering mushroom logs with soil in a wall style: inside the shed, lay a ridge of soil 15-20 cm thick along the length of the mushroom bags, and remove the plastic bags from the mushroom logs that have fully colonized and are about to fruit. Arrange the mushroom logs neatly on the soil ridge. Cover each layer with 3-4 cm of soil, 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; 6-9 layers can be arranged, and the top layer must still be covered with soil and smoothed. After the wall is completed, spray a heavy watering once so that the covering soil absorbs enough water. This method can increase the yield of oyster mushrooms by 50-90%.

Moisture retention by covering the bag openings with nutrient soil: 45 kg of fertile soil, 5 kg of plant ash, and the amount of water added should be such that when you grab a handful of soil and release it from a height of 1 m, the soil is ideally able to fall to the ground and scatter. Bag cultivation and management are the same as conventional methods, except that 2-3 cm thick nutrient soil is placed into each of the two ends of the bag. During the fruiting period, spray water on the nutrient soil 1-2 times a day. This method can increase the yield by 50%.

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