菊花一般在十月中旬开花,但通过人工控制,一年四季都能开花。菊花是短日照植物,光照时间长短对花芽的形成起主导作用。缩短光照时间可促进花芽形成,提早开花,延长光照时问可抑制花芽形成,推迟开花。如果你要在春节赏菊,可在八月中旬扦插,育苗一个月后上盆,天冷后先移进低温温室,到十二月中旬移到栽培温室,春节即可开花。如果你要“五一”看花,可在十一月底,将开过花的秋菊残株剪除地上部份,换盆后放18℃条件下培养,使新芽苗壮生长,到
Chrysanthemums generally bloom in mid-October, but can be flowered throughout the year by manual control.

After it is cold, it will be moved to a low-temperature greenhouse and moved to a cultivation greenhouse in mid-December. If you want “May Day ” to see flowers, at the end of November, the flowering Qiuju stubble cut off parts of the ground, after the change pots placed 18 ℃ under the conditions of the growth of new shoots sprout, to
