Whether it is seed sowing, vegetable planting, or flower cultivation, horticultural greenhouse devices are gradually being adopted, among which plastic greenhouses are especially adopted by the majority of vegetable farmers. Among the existing plastic greenhouse technologies, the most commonly used is a fixed plastic greenhouse built on-site with bamboo strips. A bamboo strip is bent into an arc shape, and the two ends are deeply inserted into the mud. Multiple bamboo strips are inserted in rows according to this method, and covered with plastic film to build a plastic greenhouse for farming. With the development of technology and the improvement of materials, the sheds of plastic greenhouses are gradually replaced by plastic poles or metal poles, making plastic greenhouses more and more solid, large-scale, and with a longer lifespan.

The most primitive method is to bury the edge of the film in the soil or fix it on the scaffolding with clips, which makes the film fixing work quite troublesome and the fixing quality cannot be guaranteed. It cannot withstand wind and rain, especially in typhoon season. Since the greenhouse film is not firmly fixed, the film may be blown into pieces, which not only damages the greenhouse, but also affects the growth of plants in the greenhouse.
