[0001] The invention relates to the technical field related to concrete maintenance, and specifically to a construction method and device for a greenhouse with comprehensive heat storage in winter. Background Art

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening.
