Abstract: It is important for the solar greenhouse to study the environment index of greenhouse inside and it will improve the performance of greenhouse and the adaptability of crop on environment. This paper studied the change rule of solar greenhouse environment and its relation with the matrix of potted flowers. The results showed that the temperature, intense of illumination of single or double-layer membrane solar greenhouse elevated differently along with the outdoor temperature and intense of illumination elevating, but the peak of temperature appeared at the same time with the intense of illumination. Change of the temperature and illumination intense of greenhouse would be kept smooth after using artificial management, and wave of the temperature and illumination intense of double-layer membrane solar greenhouse were more calmly than that of single-layer membrane solar greenhouse; The temperature and water content of potted matrix were affected by indoor environment, The speed of temperature rise and drop of double- or single-layer membrane greenhouse were smaller compared with outside. The matrix temperature and the water transpiration rate elevated along with temperature, light elevating indoors, and their transpiration capacity would come to a peak from 12 to 18 o'clock whether plant or potted matrix.
