Abstract
A solar heat reservoir for further increasing the underground and ground temperature of a plastic greenhouse to improve the crop yield belongs to the field of further application of solar energy in plastic greenhouses. Heat collection boxes are arranged in front of a plastic greenhouse. Heating pipes are arranged in the ground, and one end of each heating pipe is connected with the air outlet of the corresponding heat collection box. A return pipe is arranged below each heating pipe, one end of each return pipe is connected with the air inlet of the corresponding heat collection box, and the other end of each return pipe and the other end of the corresponding heating pipe are connected to form a circulation airway. After the sun shines on the heat collection boxes to heat the air in the heating field, the heated air flows into the higher heating pipes; and after the air in the heating pipes heats the ground, cooled air returns to the heat collection boxes through the return pipe to be heated again. Thus, solar energy is stored in the ground, the temperature of air in the greenhouse rises during the day, and the heat stored in the ground is released to heat the ground air when there is no sunlight at night. The yield of crops in the greenhouse is improved due to the increase of temperature.
