Description

Technical Field

[0002] Plastic greenhouses are widely used in agriculture, animal husbandry, and other fields. Taking agriculture as an example, plastic greenhouses are a simple and practical protected cultivation facility. Due to their ease of construction, convenient use, and low investment, they have been widely adopted by countries around the world with the development of the plastics industry. Using materials such as bamboo, wood, and steel, and covering them with plastic film, arched sheds are constructed for cultivating vegetables. This allows for earlier or later supply, increases yield per unit area, and helps mitigate natural disasters. In particular, it ensures a supply of fresh vegetables during the early spring and late autumn off-seasons in northern regions.
