[0002] Greenhouses are made of bamboo poles, cement poles, light steel pipes or pipes as the skeleton, and are made into columns, pull rods, arch rods and pressure rods, covered with plastic film to form an arched material shed. Greenhouses need to be built in sunny, windproof, dry and well-drained places. Plastic greenhouses generally cover an area of ​​1-3 acres. Greenhouses are widely used in agriculture as an environmentally friendly planting method.

[0003] Existing environmentally friendly agricultural greenhouses mostly use light steel pipes as the skeleton during use. Light steel pipes can fully support the greenhouse film under natural conditions. However, when encountering blizzards, as the snow accumulates, the pressure on the light steel pipes will become greater and greater, and eventually the greenhouse will collapse due to bending, resulting in a shorter service life of the greenhouse and poor wind and snow resistance. Therefore, an environmentally friendly agricultural greenhouse is urgently needed to solve the above problems. Utility Model Content
