Compared with potted chrysanthemums, cut chrysanthemums are mainly used for sacrifices and funerals, and will replace burning paper in the future, which is one of the symbols of civilized sacrifices. The consumption of Chinese chrysanthemum will increase significantly. At present, domestically produced chrysanthemums are mainly sold to South Korea and Japan.
The international chrysanthemum cutting industry with a 15-year long history, has the characteristics of mature industry, huge scale, huge potential and complete technical system. There are various kinds of cut chrysanthemums. The ultimate goal is to establish technical specifications for supplementary lighting covering the world's major varieties of chrysanthemums; to establish technical standards for supplementary lighting for chrysanthemums suitable for different latitudes, varieties, and technical models.
The purpose of supplementing light for chrysanthemums is to inhibit flower bud differentiation and maintain vegetative growth so that the chrysanthemum does not bloom, and the annual production is realized.
The difficulty of supplementing light for chrysanthemum is to make sure high reliability under the premise of low cost. High reliability includes: reliable inhibition of flower bud differentiation, low failure rate and long lifespan of supplemental lighting fixtures (Like LED grow lights).

Challenge |
Measured by PAR, the lighting efficiency of LED is high, but it is not high enough for the application of supplementing light for chrysanthemum. |
The illuminance at the lowest point is greater than 1umol/m2s, and the installation height is 1.6 meters within 3*3 square meters. |
The effective light intensity required for cut chrysanthemums should not exceed 1umol/m2s within the wavelength of 660~730nm. |
The ambient temperature is 40°C for 100 hours, and the light decay is less than 1%. |
Replacement for incandescent lamps and energy-saving lamps |
