昙花原生于美洲热带及印度,喜欢温暖阴湿的热带雨林环境,属于附生植物,生长适温为24～30℃。有些人认为昙花冬天休眠,这是一种误解,昙花在冬天是没有休眠期的。我栽培昙花多年,发现昙花在11月至次年5月是营养生长期;进入6月后,温度升高,进入生殖生长期,从6月～10月开花不断,几乎每月都有。有的花蕾生成时间较晚,在11月上旬还能开放(入室后)。10月上旬入室后,进入新一轮的营养生长期,直到来年5月。这是我6年来的实践得出的结论。我的昙花每年5月中旬出室,此时气温较稳定,对昙花苗株生长不会有影响。置于北向阳台上,一直管理到10月初。湿度不足时增
Epiphyllum native to tropical America and India, like the warm and humid tropical rain forest environment, belonging to epiphytes, growth temperature of 24 ~ 30 ℃. Some people think that Epiphyllum dormancy in winter, this is a misunderstanding, Epiphyllum in the winter there is no dormant period. I cultivate Epiphyllum for many years and found that Epiphyllum in November to next May is the vegetative growth period; into June, the temperature rises into the reproductive growth period, flowering from June to October, almost every month. Some flower buds are late, open in early November (after entering the room). After entering the room in early October, it enters a new round of vegetative growth period until May next year. This is my 6 years of practice concluded. My epiphyllum leaves the room every May in mid-year, when the temperature is more stable, it will not affect the growth of the blight. Placed on the north balcony, has been managed until early October. Increase when humidity is low
