China is the first major tobacco producing country in the world, and the tobacco industry plays an important role in national economy; the optimum temperature of tobacco in the growing period of China is 25-28 ℃, and the sunshine duration is required to be more than 600 hours. At present, tobacco planting is seriously influenced by external environment, the tobacco plants are thin and small due to low illumination intensity, insufficient illumination time and frequent frost in a seedling growing period and a growing period, the stress resistance is poor, and the yield and the quality of tobacco leaves are greatly influenced. In the special seedling raising period, insufficient illumination causes slow seedling development, the seedling raising period is prolonged, the cost is increased, and the quality of tobacco seedlings seriously affects the yield and the quality of tobacco. At present, most of artificial light supplement in the seedling raising period adopts a traditional three-primary-color fluorescent lamp, the spectrum of the fluorescent lamp is designed according to the selectivity of human eyes to light, the product design meets a luminosity system evaluation system, the fluorescent lamp is not suitable for plants, part of bands in the spectrum are not required for plant growth, the light energy is greatly wasted, the operation cost is increased, and meanwhile, the fluorescent lamp has the defects of high energy consumption, short service life, easiness in breakage and the like. Therefore, many scientific researchers or manufacturing enterprises carry out a large amount of researches on the aspect of tobacco planting supplementary lighting, and certain achievements are achieved. For example, menglin and the like adopt a water culture mode, and utilize red and blue monochromatic light to improve the seedling light environment so as to improve the quality of tobacco seedling (literature: menglin, songhun Jing, wang Chengdan, xuyimin); zhouzhi and the like utilize an LED light source with the wave peak between 630 and 660nm to carry out tobacco seedling culture light supplement, and can promote the yield and the quality of tobacco to a certain extent (literature: zhouzhi, shushujie, liuqing lingling, yang Jianqu, liuying, euro bright, huanghao and Gong Ting); CN105532210A discloses a tobacco seedling growing method based on a luminous environment; CN102150540A discloses a tobacco plug seedling method combining artificial light and natural light; CN105165437A discloses a method for promoting tobacco seedling growing by using LED plant growing light source. However, since the growth of plants is a combination of different light qualities, the light qualities used by the above researchers are relatively single and incomplete. For practical applications, problems still remain: 1. specific spectral energy distribution is not provided for seedling culture or growth period, and production cannot be guided; 2. the cultivation scheme of the whole growth process from sowing to harvesting of the tobacco in the completely artificial light environment is not provided.
