History and function

1957 was popularized and used in Tianjin, Shenyang, Northeast China, Taiyuan and other places from Beijing, and was welcomed by all localities. 1958 China has been able to produce agricultural polyethylene film by itself, so the production of vegetables covered in sheds has been very extensive.

In the mid-1960s, the shed was arched, with a height of about 1 m and a width of 1.5-2.0 m, so it was called a small arch shed. Because the shed type is short and not suitable for application in the cold area of Northeast China, 1966, the small arch shed was first converted into a 2-meter-high square shed in the suburbs of Changchun. However, it collapsed because of its poor snow resistance. After repeated reconstruction and trial use, it finally created an arched greenhouse with a height of about 2 meters, a width of 15 meters and an area of 1 mu.
