PROBLEM TO BE SOLVED: To provide a plant cultivation system capable of efficiently reducing room temperature in a plant cultivation facility by using cold energy generated by decomposing carbon dioxide hydrate, increasing carbon dioxide concentration in the plant cultivation facility, and promoting photosynthesis of plants.SOLUTION: CO2 hydrate is decomposed into CO2 and water by using a CO2 hydrate decomposition device 4, the decomposed CO2 is supplied into a facility H, so that CO2 concentration in the facility H can be increased, and photosynthesis of plants can be promoted. Further, cold energy generated by decomposing CO2 hydrate is heat-exchanged with air in the facility H through a heat exchanger 5. Therefore, room temperature in the facility H can be efficiently reduced. |
