The greenhouse is an upgrade of the greenhouse, which is actually a super large greenhouse. The original independent single-room greenhouse is connected with the original independent single-room model greenhouse by scientific means, reasonable design and materials. Features: 1. Compared with traditional greenhouses, the greenhouses and greenhouses in the form of connected buildings are a highlight compared with the traditional greenhouses, and their utilization area is far greater than that of traditional greenhouses. 2. More unified management, more scientific operation, time saving and extraction rate than traditional greenhouse. Function: the greenhouse is an economical greenhouse, which is popular with users for its graceful curve shape and low cost. Arcuate room top is beautiful and easy, line of sight is fluent. Small amount of structural steel, good insulation performance. Manufacturing cost is relatively low, is an economic greenhouse, suitable for most areas in China. In the north, double-film greenhouses are used, while single-film greenhouses are used in the south. Light can be obtained within the visible light range of 0.4 to 0.7 micron. After the film is inflated, a thick air bag can be formed, which can effectively prevent heat loss and prevent the invasion of cold air. The double-layer air-filled film can greatly improve the thermal insulation performance of the greenhouse and save operating costs. The top of the covering material is covered with polyethylene drip-free longevity film. The outer layer is uv resistant and the inner layer is dew resistant. According to the needs of users around the use of polyethylene drip - free longevity film or polycarbonate hollow plate cover.
