Greenhouse sit to: Greenhouse to be built facing south and west (yin) 3--5 degrees as well. This direction, accepting the sun for a long time, energy utilization. Ruoyin topography and other reasons, can not reach the above requirements, it should try to adjust it so that at 10 degrees west to east within the range of 5 degrees. As follows: between 12:00 to 12:20, on the ground insert a vertical pole, through observation, select its shortest projection, and then do the vertical line, then the vertical line prevail, partial shade 5 degrees draw a straight line straight line drawn nursery greenhouses offer, namely the direction of the reference line the back wall of the greenhouse. 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 nursery greenhouse construction company, with the angle of incidence of the increase in greenhouse nursery cost, light incident rate decreased, but did not change significantly, while after the incident angle greater than 40 degrees, with the angle of incidence increases , its transmittance significantly even dramatically.
