Therefore, it is recommended that farmers and agricultural production enterprises with sunlit greenhouses, especially those with earthen walls, pay attention to preventing rainwater erosion and erosion of exposed walls and back slopes. Felt and plastic film can be covered on the exterior and back slopes of the walls to prevent rain.
