Environment-friendly orchid cultivation temperature control system

The invention discloses an environment-friendly orchid cultivation temperature control system which comprises a frame body, an upper cavity is formed in the top of the interior of the frame body, a lower cavity is formed in the bottom of the interior of the frame body, and a connecting hole is formed in the position, located at the rear end of the upper cavity, of the frame body; by means of the advantages that when the temperature in the upper cavity rises, the irrigation efficiency of orchids is improved, absorption of water and nutrients is improved, and flowers bloom, when the temperature is reduced, the irrigation efficiency of the orchids is reduced, water can be saved, diseases and insect pests can be prevented, dormancy can be promoted, and the situation that roots are rotted due to accumulated water is avoided; the water level in the water tank is detected through the floating block, and then opening and closing of the two blocking blocks are adjusted, so that water exists in the water tank all the t
