Plant planting method

The invention discloses a plant planting method. The plant planting method comprises the following steps: arranging a thin film above a plant canopy surface in any growth stage, and forming through holes in the surface of the thin film. The thin film enables visible light of a single dominant color to be formed below the thin film after sunlight irradiates the thin film, and the through holes enable the irradiation spectrum of the sunlight penetrating through the through holes below the thin film to be unchanged. According to the plant planting method, through the single-color film with the holes, the light quality of the irradiated plant surface is changed, and meanwhile, it is also ensured that the plant can receive ultraviolet irradiation, so that healthy growth is ensured. In field cultivation, the method is simple, convenient and controllable, can widely simulate different light quality and spectrum conditions, and is a reusable cultivation method. The method is more targeted, can better adapt to differe
