The height of the north-south span Greenhouse: height and north-south span, should be based on the latitude to be. Because height and span greenhouse lighting surface determines the angle, the angle of light around the sun again face the size of the angle of incidence. Ensure greater sunlight incident rate should be less than 40 degrees angle of incidence. Because the sun's angle of incidence of light projected rate closely. Its angle of incidence in the range of 0-40 degrees, with the angle of incidence of new greenhouse construction price increases, the rate of incidence of light down, but did not change significantly, while after the incident angle greater than 40 degrees, with the angle of incidence increases, the permeability sharp decline significantly even light. Greenhouse lighting surface of the transparent cover material: To adopt light, no drops, dust, good thermal insulation properties of new greenhouse manufacturers, and has a strong tensile membrane longevity. Winter and spring in order to maintain a certain temperature level in the greenhouse to ensure normal growth temperature of new greenhouse vegetables, if necessary, would require heating. According to weather and temperature changes in ventilation, sunny greenhouse warming fast new design can be as early as ventilation, shade snow slow warming, ventilation can be late.
