Plant factory UV artificial light control has high application value in achieving high-quality and high-yield facility gardening, but the application dose and irradiation time should be selected according to the crop type and application target to ensure application safety. For the selection of crop types, facilities vegetables, medicinal plants, flowers and fruit trees can all be applied; the main application targets are to control the growth of plants and improve the quality of agricultural products, such as increasing the content of antioxidants in vegetables and increasing secondary metabolism in medicinal plants Accumulation of substances, etc., accelerate the synthesis and accumulation of color-developing substances in flower leaves and petals.
From a safety perspective, based on the physiological needs and quality control goals of facility horticultural crops, reasonable intelligent light environment management measures should be formulated to avoid UV exposure to the human body, so that UV can play its role in quality control and improve the commodity of facility horticultural crops. Value and nutritional health function. For example, you can take supplemental photos at night and stop during the day.
Application and Strategy of UV Artificial Light Regulation in Plant Factory
Plant factory UV artificial light control has high application value in achieving high-quality and high-yield facility gardening, but the application dose and irradiation time should be selected according to the crop type and application target to ensure application safety.

In order to control the effect of ultraviolet light control, the dose of UV radiation must be well controlled. Short-term low-dose applications, intermittent repeated irradiation, and short-term pre-harvest irradiation can be used to reduce the dose. In terms of lamps, UV lamps are currently available on the market, but UV-LED light sources will be the preferred electric light sources for UV light regulation, which can be accurately positioned and illuminated.
