Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of Primulina cultivation, and particularly relates to a plant type regulation method of Primulina. BACKGROUND

[0002] Primulina is an extremely rich genus in species diversity among Gesneriaceae plants, with more than 200 species. It has the characteristics of dwarf compact plant shape, large and beautiful flowers, strange and interesting leaves, unique and significant shade tolerance and drought tolerance, and easy propagation. In recent years, it has been deeply appreciated and favored by the majority of the people.

[0003] Primulina plants can be developed as ornamental potted plants, and their ornamental nature is different depending on plant type, flower size and number, and presence or absence of leaf mottling. Most species in Primulina have compact and beautiful plant types, such as Primulina baiyushou, Primulina liuijiangensis, Primulina purpurea, Primulina liboensis, Primulina acutifolia and Primulina yongfui, which can be placed indoors and on balconies for flower and leaf viewing; such as Primulina chingii and Primulina petiolata, which have small and delicate plant types and are suitable for use in miniature bonsai; and such as Primulina textori, Primulina spinodentata, Primulina striata and Primulina spinosa, which have obvious leaf succulence and beautiful plant types after years of cultivation, and are excellent materials for making bonsai.

[0004] Primulina plants are usually cultivated under facility conditions. Under facility conditions, the needs of plants for light and temperature can be met, and the plants can obtain good growth under artificial water and fertilizer management. However, good growth environment and sufficient nutrient supply can also lead to rapid plant growth and large plant type. Since the leaves of Gesneriaceae plants are fragile, large plant type is prone to mechanical damage during transportation, which not only affects the ornamental nature but also greatly reduces the commodity value. In addition, large plant type also reduces the use value of some species (such as those used in miniature bonsai). Therefore, the cultivation of Primulina plants should be controlled to make the plants dwarf and compact, which is not only beneficial to the circulation and transportation of the plants as commodities, but also beneficial to the improvement of their ornamental nature and use value. However, in existing research, there is little research on the cultivation control of Primulina plants, especially on the regulation of plant shaping. SUMMARY

[0005] The present application aims to provide a plant type regulation method of Primulina, to solve the problems in the prior art in the background.
