Cover layer structure for increasing and protecting temperature of soil

The utility model relates to a cover layer structure for increasing and protecting the temperature of a soil body. The cover layer structure comprises a light-transmitting heat preservation layer (1) and a light-transmitting single-face reflection layer (2) arranged on the bottom face of the light-transmitting heat preservation layer (1). A plurality of compartments are arranged in the light-transmitting heat preservation layer (1) and filled with air. And the light-transmitting single-sided reflecting layer (2) transmits light from top to bottom and reflects light from bottom to top. According to the utility model, a composite structure combining heating and heat preservation is creatively provided, solar radiation in the daytime is fully utilized to heat a soil body, and meanwhile, the heated heat can be effectively stored in the soil body, so that the soil body is rapidly heated and finally maintained at a higher level, and a better soil body anti-freezing effect is further realized; meanwhile, natural con
