Arched shed, also known as low shed, requires a door shaped steel pipe to be built. The production method is to bend a 3-meter-long and 8mm diameter steel pipe into a door shaped structure with a top length of 1 meter and 1 meter on each side. A door shaped steel pipe is inserted every 2 meters as the skeleton of the arched shed. The steel pipe needs to be inserted into the soil layer for about 0.3 meters to ensure the stability of the arch. Connect each door shaped steel pipe with a support film line, and then lay a sunshade net. The sunshade net is the same as the sunshade net used in the shed, with a shading rate of 75%. In areas without sprinkler irrigation conditions, there must be sufficient water sources to water the morel mushroom beds with water pipes.
