Shed the history and function: 1976 Taiyuan suburb built shed 29 different specifications for the greenhouse roof structure, the construction of the scale provides a wealth of experience. Greenhouse production in 1978 has been extended to the southern parts of the country has reached 10 million mu of greenhouse area. So far, the country has been basically stable in the greenhouse area of ??over 10 acres. Which in our arid region in northern provinces, municipalities and about 70,000 acres. Features greenhouses: the lighting conditions. Generally the film is also easily adsorb water vapor condensed into water droplets on the film cost greenhouses skeleton, making the film transmittance decrease 10-30%. Therefore, to prevent contamination of the film, to prevent the agglomeration of water droplets is an important measure. Furthermore film greenhouses during use skeleton manufacturers, due to the high temperature, low temperature, and the influence of ultraviolet sunlight, the film "aging." After aging film transmittance rate decreased by 20-40%, and even loss of use value. So the film greenhouses covering should be used in anti-aging temperature, dust and drip-free membrane to enhance shed the light, warming and extended use period.
