Greenhouse vegetable production was originally dedicated equipment, yin and yang greenhouse manufacturers, along with the development of greenhouse production applications become increasingly widespread. Greenhouse shade covering the role: a cooling effect. Shade network coverage due to the greenhouse temperature has dropped, particularly the largest, 10:00 surface and soil tillage layer cooling rate - 2:00 p.m., the yin and yang cost greenhouse, shed the upper temperature up to 37-40 ℃, yin and yang, greenhouse, and the surface Plants ambient temperature at 22-26 ℃, the yin and yang greenhouse construction manufacturers, the soil temperature is between 18-22 ℃, suitable for crop growth. Greenhouse vegetable production was originally dedicated equipment, along with the development of greenhouse production applications become increasingly widespread.
