北方地区瓜叶菊多作一年生花卉栽培,秋季温室内播种,春季开花,夏季采种。其中,冬季管理是否适宜,是开花繁茂与否的关键。以下从几方面说明冬季的管理方法: 1.温度瓜叶菊生长适温为10～13℃左右,不耐高温,超过15℃,容易徒长,幼苗期生长适温7～8℃,在此温度下可防止幼苗徒长,适合幼苗的“蹲苗”。但是温度低于0℃时,易受冻害,在花蕾待放时,如果要促使花期提前,应提高温度至12～15℃;如果要延缓花期,可以维持7～8℃左右的室温。 2.光照通常要置于阳光充足、透气良好的地 Cultivated annual flowers of cineraria in northern China are mostly planted in the greenhouse in autumn, blooming in spring and collecting seeds in summer. Among them, the winter management is appropriate, is the key to flourishing or not. The following aspects of winter management methods from the following aspects: 1. Temperature The growth of cineraria appropriate temperature is about 10 ~ 13 ℃, high temperature, more than 15 ℃, easy to grow, seedling growth temperature 7 ~ 8 ℃, at this temperature Prevent seedlings tricky, suitable for seedlings “Dunmiao.” However, when the temperature is below 0 ℃, it is susceptible to frost damage. If flower buds are ready to be put on, the temperature should be raised to 12-15 ° C if the flowering period is to be advanced; and the room temperature should be maintained at about 7-8 ° C if the flowering period is to be postponed. 2.
