PROBLEM TO BE SOLVED: To provide a method for cultivating plants even under the conditions in a plastic greenhouse wherein the near ultraviolet rays are cut off but the pollination action of insects, particularly of bees can be supported. SOLUTION: In a plastic greenhouse for agriculture, transparent covering material that substantially interrupts more than 70% of the light of 370 nm wavelength and substantially interrupts the light of 350 nm wavelength or less is used to prepare a plastic greenhouse from which near ultraviolet rays are interrupted. In this partially light-interrupted plastic greenhouse, light emitters that radiate the ultraviolet rays of 330 to 390 nm wave length are allowed to radiated, while the insects, for example, bees work for pollination.
