The advantages of this greenhouse, one is to better improve the temperature inside the greenhouse. In the local outside temperature reaches minus 30 ℃, hanging in the room a layer of canopy. Can control the minimum soil temperature above 9 ℃, for the greenhouse cucumber in advance, delayed cultivation, and create a good environment for reproduction. The second is to increase the transmittance, to overcome the original structure of the greenhouse roof pillars of the lack of light
