Description

Technical Field

[0001] The invention belongs to the technical field of Primulina cultivation, and particularly relates to a plant type regulation method for Primulina plants. Background Art

[0002] Primulina is a genus with extremely rich species diversity in the Gesneriaceae family, with more than 200 species. It has the characteristics of short and compact plant shape, large and beautiful flowers, strange and interesting leaves, unique and significant shade and drought tolerance, and easy reproduction. In recent years, it has been deeply appreciated and favored by the general public.

[0003] Plants of the genus Primulina can be developed into ornamental potted plants, and their ornamental value varies depending on the plant shape, flower size and number, and the presence or absence of leaf patterns. Most species of the genus Primulina have compact and beautiful plant shapes, such as Primulina baishouensis, Primulina liujiangensis, Primulina purpurogena, Primulina liboensis, Primulina apex, and Primulina yongfuensis, which can be placed indoors or on balconies for viewing flowers and leaves; Primulina zhongyueensis and Primulina stone butterfly-shaped, which have small plant shapes and obvious rosette shapes, can be used for miniature bonsai; and Primulina wencaiensis, Primulina thorny-toothed, Primulina stripe-leafed, and Primulina thorny-wart, which have obvious fleshy leaves and have beautiful plant shapes after years of cultivation, are excellent materials for making bonsai.

[0004] Primulina plants are usually cultivated under facility conditions. Under facility conditions, the plant's needs for light and temperature can be met, and with proper artificial water and fertilizer management, the plant can achieve good growth. However, a good growth environment and sufficient nutrient supply can also cause the plant to grow too fast and become too large. Because the leaves of Gesneriaceae plants are brittle, the plants are prone to mechanical damage during transportation if they are too large, which not only affects their ornamental value but also greatly reduces their commercial value. In addition, the excessive size of the plant will reduce its use value for some species (such as those used in miniature bonsai). Therefore, the control and maintenance of Primulina plants to make the plants dwarfed and compact not only facilitates their circulation and transportation as commodities, but also helps to improve their ornamental value and use value. However, in existing research, there is very little research on the control and maintenance of Primulina plants, especially on the regulation of its plant shaping. Summary of the invention

[0005] The object of the present invention is to provide a method for regulating the plant type of Primulina plants, so as to solve the problems existing in the prior art in the background technology.
