| Abstract: Grapes, as one of the important fruits in China, have become a characteristic pillar of rural revitalization due to their rich nutritional value and extensive market demand, which play an important role in promoting agricultural efficiency and increasing farmers' income. With the development of rain-sheltered cultivation technology and dormancy-breaking technology, it has gradually developed into a characteristic advantageous location in the southern region from an unsuitable area for grapes. Compared with open field cultivation, protected cultivation can avoid the influence of a bad environment, reduce the occurrence of diseases and insect pests, improve yield and quality, and promote the early/late market of grapes by adjusting the production date, to improve planting efficiency. However, due to the greenhouse structure and cover shielding, resulting in reduced light in the facility, spectral composition changes. Light is an important factor affecting the growth and development of grape, low light environment not only reduces the photosynthesis of grape leaves but also leads to excessive plant growth, fruit quality decline and other problems, seriously restricting the sustainable development of the grape industry. In recent years, with the extensive application of supplementary lighting technology in protected horticulture production, there are more and more researches on artificial supplementary lighting technology of protected grapes. In this paper, the related research report on grape supplementary light technology at home and abroad is summarized. Firstly, the types, characteristics and application of common artificial supplementary light sources in the existing supplementary light technology are summarized. Among the artificial supplementary light sources such as thermal radiation light sources, gas discharge light sources and electroluminescent light sources. The light emitting diode (LED) of electroluminescent light source has the advantages of less heat generation, energy saving and high efficiency, stronger wavelength adjustability, accurate spectrum control and long service life. Secondly, the effects of different light quality, light intensity and photoperiod on grape growth and development were analyzed comprehensively, and the suitable light formula was obtained (light quality, light intensity, photoperiod) that can significantly promote photosynthesis of grape, and improve yield and fruit quality. Finally, the paper prospected from the aspects of light formula, plant physiological mechanism, the synergistic effect of multiple environmental factors, development of energy-saving supplemented light and intermittent light supplement technology of plants. It was considered that artificial supplemented light was an effective way to improve the light environment of protected grape production and solve the problems of weak light and insufficient light time. Meanwhile, the light formula should be combined with plant variety and cultivation environment optimization to comprehensively improve the production efficiency of protected grapes. This paper summarized the types and characteristics of supplementary light sources, the effects of supplementary light technology on grape growth and development, and the development trend of supplementary light technology, in order to provide a reference for the research of grape protected cultivation. |
