Dragon fruit has a good market prospect for its good taste and high nutritional value. At the same time, since its planting conditions are easy to meet, dragon fruit is widely planted in many regions of China. However, the problem of insufficient sunlight in spring and winter still leads to an insufficient supply of dragon fruit production. To improve the quality as well as the annual supply cycle of dragon fruit fresh fruit, and improve the economic benefits of dragon fruit cultivation, fruit growers generally use artificial light supplementation technology to regulate the flowering cycle of dragon fruit to prolong the production period. This paper reviews the impact of different light qualities, light intensities, and photoperiod on the production and quality of dragon fruit, and summarizes the shortcomings of the existing supplementation technology. The feasibility of the combination of photovoltaic, energy storage, and dragon fruit light supplementation technology is also comprehensively analyzed, and the outlook is put forward, aiming to provide a direction for the further development of dragon fruit light supplementation technology.
