Abstract:

This paper described the effects of light quality control on the growth and development, nutrient metabolism and photosynthesis regulation mechanism of main Leguminous and Gramineous forage (Medicago, Trifolium, Lolium, Festuca, Avena, Miscanthus and Zea), and pointed out that light quality was closely related to important indicators such as organ development, metabolite accumulation and photosynthetic physiological parameters of forage. Then, according to the application frontier of light supplementation technology on horticultural crops, fruits and vegetables, the development and focus of light regulation technology on forage were discussed. It is suggested that the light source selection and the agronomic traits of forage should be precisely linked, and the synergistic effect of multiple environmental factors should be fully exploited in combination with information science technology to maximize the use of light.

Key words: forage, light quality regulation, photosynthesis, Leguminosae, Gramineae
