Abstract

The invention discloses an LED light source and a preparation method and an application thereof, and a method for regulating the flowering time of plants. The LED light source includes a blue light chip and mixed phosphor coating the blue light chip, and the mixed phosphor includes red phosphor and yellow-green phosphor. The emission spectrum of the LED light source includes blue light, green light, red light and far-red light, and the light energy ratio of the blue light to the green light to the red light to the far-red light is (5-15):(10-35):(50-70):(1-5). The flowering time of plants canbe regulated more precisely, and the market value of plants with flowers or fruits as the commodity value can be maximized.

Description

technical field [0001] The invention belongs to the field of plant lighting, and in particular relates to an LED light source, a preparation method and application thereof, and a method for regulating the flowering period of plants. Background technique [0002] In nature, the main factors affecting plant flowering are temperature and photoperiod. Flowering plants in nature are divided into long-day plants, short-day plants and neutral plants according to their different responses to photoperiod. According to the flowering mechanism of plants, the flowering period of plants can be regulated by regulating the photoperiod of plants. It can not only make the plants not bloom during the natural flowering period, but also make the plants bloom during the non-natural flowering period. For plants whose commodity value is flowers and fruits, it is possible to increase the value of products through staggered listing. [0003] At present, the means to regulate the flowering period ...
