GREENHOUSE CULTIVATION SYSTEM

PROBLEM TO BE SOLVED: To provide a greenhouse cultivation system capable of effectively using energy, and enabling low-cost high-quality cultivation of abundant yield. SOLUTION: This greenhouse cultivation system has a gas turbine 1, an electric generator 2 having the gas turbine 1 as a power source, and an exhaust heat recovery device 3 recovering heat from exhaust gas from the gas turbine 1. The cultivation system comprises arranging a denitration device 5 which lowers the nitrogen oxide concentration of exhaust gas from the gas turbine 1 to a value allowing not to damage crop raising in greenhouse cultivation, between the gas turbine 1 and the exhaust heat recovery device 3, supplying exhaust gas containing nitrogen oxide of concentration lowered not to damage crop raising, to the exhaust heat recovery device 3, and supplying heat and carbon dioxide from the exhaust heat recovery device 3 to a greenhouse for performing crop raising followed by supplying electric power from the electric generator 2 to the greenhouse 4.
