Description

Luminous environment for promoting succulent plant coloring

Technical Field

The invention relates to the technical field of ornamental plant indoor cultivation, in particular to a luminous environment for promoting succulent plant coloring.

Background

Succulent plant is a plant with at least one of the three nutritive organs of root, stem and leaf being thick and succulent and having the function of storing a large amount of water. With the improvement of living standard of people, people have higher and higher pursuit of beauty, the family demand of planting bonsai vegetables or various succulent plants indoors is increased, and the succulent market is developed. The high-quality succulent plants are compact in plant type, bright in leaf color, high in ornamental value and wide in market demand. However, when succulent plants are planted indoors, due to insufficient illumination or poor spectrum, excessive growth and poor coloring often occur, and the ornamental value and economic value of succulent plants are greatly reduced.

The color of fleshy meat depends on its anthocyanin biosynthesis function and is determined by both plant genes and the external environment. The light is one of the main environmental factors influencing the growth and development of plants, is not only an energy source for photosynthesis of the plants, but also serves as a signal for regulating photomorphogenesis and secondary metabolite accumulation of the plants. The light quality and the light intensity can influence the synthesis of the anthocyanin to a certain extent, wherein the light quality plays a more key role.
