Greenhouses are cultivated in plastic greenhouses and are widely used in the north. It can effectively overcome the unfavorable conditions such as low temperature and dryness, and prolong the growth cycle of fungus. Under outdoor natural conditions, the annual fungus production period is from June to September, using plastic greenhouses, and the growth period is from April to December of the following year. As the plastic greenhouse can increase the temperature and maintain the humidity, the inoculation time of the ear can be carried out within half a month in advance. After the inoculation, the rack is discharged in a “well†shape in the shed, and no additional film or straw curtain is needed to cover the bacteria. When most of the ear buds appear, they are piled up in time, and the earwoods are discharged on the crossbars in a “person†shape. Due to the narrow floor in the shed, 1 to 2 floors can be placed on each side. Ear temperature during the shed to be controlled at 20 ~ 28 °C, if more than 30 °C, in the roof canopy shade, can also spray cold water to the roof and around, while enhancing ventilation and reduce the temperature within the shed. If the temperature is too low, the doors and windows should be closed in the afternoon when the temperature drops, and the straw curtains should be stamped. The curtains will be uncovered the next morning and the sun will be used to warm up. After summer, when the outside temperature is stable above 20°C, the film can be removed and the planting can be performed in situ. However, the sun still needs to be shaved to avoid direct sunlight. The temperature drops gradually after the undulation and can be covered with a plastic film. Spray water into the shed every morning and evening, so that the humidity reaches 80% to 90%. After picking the ear, temporarily stop the water spray, lift the film, and dry it for 3 to 4 days so that the ears can fully receive the sunlight and air to encourage the growth of mycelium and then seal the water.
