[0002] The material covered by the greenhouse is plastic film. It is suitable for large area coverage because it is light in quality, good in light transmission and heat preservation, strong in plasticity and low in price. In addition, it can use light skeleton material, is easy to build and shape, can be taken locally, has less construction investment and higher economic benefit. It can also resist natural disasters, prevent cold and preserve heat, resist drought and waterlogging, cultivate early and late, and prolong the growth period of crops to achieve the purpose of early maturity, late maturity, yield increase and yield stability, especially in cold and high-cold areas, sandy and dry areas to resist low temperature and drought and wind sand hazards.

[0003] The present breeding greenhouse is mostly single-layer shed frame structure, that is, a single body structure covered by shed film on the shed frame. In some sandy areas or areas with low temperature, the single-layer shed frame structure has low strength and is prone to deformation due to wind and sand damage.
