In order to prosper the flower market in our district and meet the requirements of urban greening and landscaping, the author introduced and cultivated the Compositae flowers: Zinnia, Xiaolihua, Calendula officinalis, and Snowy millet, and observed and recorded the data. After a year of greenhouse cultivation experiments, the results showed that: (1) Introduction or cultivation of Asteraceae flowers in the greenhouse can be pre-flowering, especially the flowering of the flowering Xiaoli significantly ahead of about 30 days. (2) The early flowering stage of Ziziphus chinensis was also obvious, but the number of single flowering decreased and the ability of twigs to shoot became weaker. (3) The Calendula officinalis plants grew well in the cultivation and the plants were robust, but the early flowering effect was not obvious. (4) Snowdrops grow vigorously for the first time in our district.
