[0002] At present, my country's edible fungus industry has become the fifth largest industry in the planting industry after grain, vegetables, fruits and oil. The national edible fungus industry has gradually formed a trend of "mushrooms expanding from the south to the north", the production area has been continuously expanded, and the high-altitude areas in the north have become the main production areas of summer mushrooms.

[0003] Edible fungi prefer a cool, humid climate. The main method of cultivating edible fungi in northern China is bag-material facility cultivation. It started late but developed rapidly. The main cultivation facilities include solar greenhouses, steel frame greenhouses, double-arch double-film greenhouses, etc. The cultivation of edible fungi is mainly achieved by simply transforming the original vegetable greenhouse facilities by replacing the greenhouse film materials, adding shade nets or thermal blankets, etc. The transformed edible fungi greenhouses have poor ventilation and cooling effects, and the yield of edible fungi cultivated over the summer is low, and even make it impossible to cultivate over the summer. The design standards of edible fungi greenhouses are different, and the greenhouse design structure and some parameters need to be further improved and adjusted. This is also one of the main technical measures to restrict the oversummer cultivation and year-round cultivation of edible fungi in northern China. Utility Model Content

The spacing between the outer greenhouse arch rod 301 and the inner greenhouse arch rod 303 is reduced from the original 1.2 meters to 1 meter, and a group of composite arch rods are arranged every 3 meters to further increase the bearing capacity of the main structure. The greenhouse foundation is opened by burying the arch rod 0.5 meters deep, and the foundation is manually compacted. Three longitudinal tie rods, 8 diagonal braces and the end column 305 of the greenhouse head are arranged to further fix the overall stability of the greenhouse. The edible fungi greenhouse of the utility model can withstand a wind load of 0.3KN / ㎡, a snow load of 0.1KN / ㎡, a constant load of 4kg / ㎡ and a crop load of 0.15KN / ㎡. The low ventilation height above the ground on both sides of the greenhouse is reduced, the film groove under the vent is 0.3m from the ground, and the vent is set to a width of 1m, and at the same time, top ventilation is increased.

The shed film is fixed with 30mm wide nano-card slots and plastic-dipped retaining springs. The outer shed 100 of the greenhouse is covered with 5 layers of thickened insulation blankets 700, which have the function of waterproofing, heat preservation and shading. During the winter production process, the utility model edible mushroom greenhouse can achieve the good effect of heat storage and protection against strong light during the day and heat preservation at night. During the production process, through the adjustment of the size of the vents, the lifting and lowering of the insulation blanket 700 and the interval opening of the micro-spray, combined with the characteristics of the overall design structure of the greenhouse, the production mode of year-round cultivation in the edible mushroom greenhouse in the northern region can be fully realized, effectively improving the output efficiency per unit land area, from the original one crop a year to 2 to 3 crops a year. Taking the cultivation of oyster mushrooms as an example, each shed can place 12,000 mushroom sticks, with an output of about 40,000 catties. Calculated at 2 yuan per catty, the output value is about 80,000 yuan. Two crops are planted each year, with an output value of 160,000 yuan. The design service life of the greenhouse is more than 5 years. Calculated at 5 years, each shed can increase the output value by 400,000 yuan, and the income increase is obvious.
