在湘北地区,3龄以上地栽的桔梗和矮大丽,6月上旬至7月上旬为盛花期。到7月下旬,桔梗果实开始成熟。不再开花;矮大丽虽仍可断断续续开花2～3个月,但因夏花繁茂,耗损甚巨,故茎叶均呈老化状态,秋花不可能开好(春播苗秋花甚佳)。若在盆菊定植期间,即7月20日这一天,将桔梗和矮大丽的茎杆齐土面砍掉,剃成光头,然后在其周围摆满盆菊,并将三者实行同一个等级的常规管理,则2～3个月后菊花开放时,桔梗和矮大丽均可二度开花,且比夏花开得更
In the northern part of Hubei Province, Platycodon grandiflorum and dwarf larvae planted above the third instar are flowering from early June to early July.

If during the period of colonization of potted chrysanthemum, that is, on July 20 this day, the stems of Campanulaceae and Dwarili will be cut off and shaved, and then the pots of chrysanthemum shall be planted around them and the same shall be practiced Level of routine management, then 2 to 3 months after the opening of chrysanthemum, Campanulaceae and dwarf can bloom for the second time, and more than the summer flowers more
