PROBLEM TO BE SOLVED: To solve such a problem that existing literature does not show a specific and practical greenhouse structure, in which what route and means (devices such as blowers and piping) are used and how the devices such as blowers and piping are arranged, to efficiently and appropriately supply air containing carbon dioxide supplied from a factory to a greenhouse and diffuse it thereinto.SOLUTION: A system supplies air containing carbon dioxide or the like to a greenhouse and diffuses it thereinto. In the greenhouse equipped with main pipes having connection parts for connecting a supply pipe for receiving air containing carbon dioxide from a factory, branch pipes are connected to the main pipes, the branch pipes are arranged to extend in the direction of spaces between plants planted in the greenhouse, and discharge pipes hang from the branch pipes. In the greenhouse, blowers are arranged to circulate air containing carbon dioxide. The blowers arranged therein can diffuse air containing carbon dioxide from the discharge pipes into the greenhouse and circulate it to the spaces between plants. |
