The size of the shed depends on the scale of cultivation, and it is generally appropriate to cultivate 110~330m2 of mushrooms per shed. Shiitake mushroom high-yield cultivation technology mushroom room setup, composting, fermentation, seeding and mushroom management bed frame arrangement mushroom beds are set up vertically with the mushroom room. Don't lean against the wall around the mushroom beds and leave a 0.6 meter wide aisle. If the mushroom room is narrower than 3 meters, only one middle aisle can be left. The aisle between bed frames is 0.6m, bed frames can be built in 4~5 layers, the distance between each layer and mushrooms is 0.6m, the bottom layer is 15~30cm from the ground, the top layer is 1.3~1.5m from the top of the trellis. the length depends on the mushroom room. The bed frame is usually built of bamboo and wood, with a pair of upper and lower windows on the wall at both ends of the aisle; the upper window is about 15cm from the canopy and the lower window is about 10cm from the ground. The size of the windows should be 40×45 cm, and a ventilation pipe with a height of 1.3 to 1.5 meters and an air cap mounted on the top should be installed in the middle roof of every 2 to 3 sheds.

In the process of composting, the nitrogen content is too low, the microbial activity is weakened, the temperature of the material is not high, the fermentation is not sufficient, and the mixing of seedlings is easy. If the nitrogen content is too high, the ammonia, amine and amide content in the fermented material is too high, which will inhibit the growth of mushroom seedlings. In production, the c/n ratio of culture material before fermentation is 30~33: 1, and the c/n ratio after fermentation is 17:1. Mushroom Sheds Mushroom shed is one of the simplest facilities for cultivating edible mushrooms, with the advantages of simple construction, easy to take materials, low cost, well ventilated, good heat preservation and humidity preservation, utilization of solar energy, diffused light and so on, and it can be adjusted to the temperature difference between day and night by lifting the cover. Simple mushroom shed is generally made of bamboo sheets into an arch-shaped trellis, both sides with bamboo poles or sticks fixed. Inside the shed, it is covered with plastic film or sunshade net, sometimes with grass curtain, and the surrounding area is firmly pressed with soil. Simple mushroom trellis is 1~2 meters wide, the length depends on the size of the field, the height is 50~70 cm, and the ground inside the trellis is covered with plow furrow, which is about 1 meter wide.

How should each facility work? Well-built mushroom shedsLarge mushroom sheds constructed of bamboo or wood as the main material are covered with awnings such as grass curtains or canvas around and on top. The actual usable area of a single greenhouse is 550m2 with a floor area of about 150m2, i.e. 20m long, 6-8m wide and 4m high. the greenhouse has 7 bed frames and 3 convection air screens of about 25cm x 30cm in size, which can be opened and closed flexibly. The bottom bed frame should be kept above 35cm from the ground and divided into 5 layers; each bed frame is 1.4~1.5m wide, the height between layers is 0.m, and the width of the walkway is 0.6~0.7m. There are mushroom trellises at the ends of each operation road, which can be constructed with steel pipes, cement frames, plastic pipes and so on. As the main material, in addition to the cultivation greenhouse constructed with bamboo and other wood as the main material; the cover can be divided into several layers, including film, felt, heat-insulating cotton, reflective film and shade net.

Mushroom sheds in the construction of mushroom housesMushroom houses are the main places for indoor cultivation of edible fungi. Conventional mushroom houses are mostly of brick wall structure, with the inner walls coated with cement or lime, and the walls and roofs are as thick and smooth as possible to minimize the influence of the external environment on the temperature inside the mushroom house. Except for the ventilation window, the mushroom room should leave no gap as far as possible, and the floor should be paved with cement or relatively flat tiles, so as to facilitate cleaning and sterilizing. Ventilation windows should be opened on the north and south walls, and the area of the windows should not be too large to control the temperature, humidity and light intensity of the mushroom room. Nylon gauze should be used for ventilation windows to prevent pests from entering. In addition, fans and exhaust fans should be installed in the mushroom room as much as possible, the roof should be equipped with extractor pipes, and the doors and windows should be oriented to the aisles to avoid the outside wind blowing directly onto the beds.
