PROBLEM TO BE SOLVED: To provide a method capable of retaining freshness in a growing state without deterioration and remarkably extending freshness of vegetables, Chinese medicine and plants such as flowers in a growing state.SOLUTION: A method for raising plants includes: by means of a plant raising device which includes a raising space 2 and a liquid fertilizer tank 3a formed in a plant raising box body 1, a cultivation bed 4 arranged in the liquid fertilizer tank 3a, a medium 5 allowing to implant seeds and seedlings of plants (A) stored in many medium holes, a carbon dioxide gas supplying device 6, a temperature setting device 7, an artificial lighting device 8 radiating artificial light, and a control means 9; irradiating plants with artificial light of a light wavelength of 350-500 nm and a light wavelength of 600-750 nm at a luminous intensity that is stronger than that of another light wavelength with the artificial lighting device 8; setting a luminous intensity ratio on artificial light of a light wavelength of 350-500 nm and a light wavelength of 600-750 nm; raising the plants by making the whole luminous intensity variable in a state of retaining a luminous intensity ratio; and after raising, preserving the plants by weakening a luminous intensity in a state of retaining the luminous intensity ratio. |
