History and function

1957 was extended from Beijing to Tianjin, Shenyang, Northeast China, Taiyuan and other places, and was welcomed by all localities. From 65438 to 0958, China has been able to produce agricultural polyethylene film by itself, so the production of vegetables covered in greenhouses has been very extensive.

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