Moisture plays a key role in guaranteeing high yield of Oyster mushroom, following are three techniques:
1. Wall Type of Mushroom Stick Moisturizing: pave a piece of ridge in accordance with the length of mushroom bags in greenhouse, which are from 15 to 20cm in depth. Take off plastic bags of mushroom bags, which are about to get fruited (called mushroom sticks). Place sticks in ridge orderly, earth 3 or 4 cm depth of soil in each row, spray water on both sides of soil, then place the second layer of sticks and earth up, 6 to 9 layers can be arranged. After making wall, people can spray more water to moisturize and get fruited in general management. This method can increase 50% to 90% of output on Oyster mushroom.
2. Earth Nutrient Soil Up in Bag Mouth: the formula is productive soil 45 kg, plant ash 5 kg, people can put 2 to 3cm depth of productive soil in both sides of bag. During the fruiting period, people should spray water on productive soil for 1 or 2 times, other management methods are in routines. This method can increase about 50% of output on Oyster mushroom.
3. Cold Frame Earthing Moisturizing: after harvesting first flush of bag-cultivation Oyster mushroom, people should peel bag and dry in the sun for 1 to 2 days to form a layer of skin on the surface of mushroom stick and prevent invading of plant diseases and insect pests, then make longitudinal incision with sterilized kitchen knife, array in cold frame, fill the gap with silver sand and cover 2 to 3cm depth of fine soil, finally pour water solution of superphosphate, monopotassium phosphate and water, the proportion is 2 : 0.2 : 1 : 100, this method can increase above 80% of output on Oyster mushroom.
