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。菊花是短期日照植物,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;延长光照时间可抑制花芽形成,推迟开花。如果你要在春节赏菊,可在8月中旬扦插,育苗一个月后上盆,天冷后先移进低温室,到12月中旬移到栽培温室,春节即可成花;如果你要在“五·一”看花,可在11月底将开过花的秋菊植株剪除地上部分,换盆后放置在18℃条件下培养,使新芽
Chrysanthemums generally bloom in mid-October, but can be flowered throughout the year by manual control. Chrysanthemum is a short-term sunshine plants, light the length of time on the formation of flower buds play a leading role. Shorten the light time can promote the formation of flower buds, early flowering; extend the light time can inhibit flower bud formation, delayed flowering. If you want to pay tribute to the spring festival, cuttings can be cut in the middle of August, one month after the nursery is put on the pot, and then moved to a cold room after it is cold and moved to a cultivated greenhouse in mid-December to form a flower in Spring Festival; “May 1” to see the flowers, flowers can be opened at the end of November Chrysanthemum cut off parts of the ground, after changing the pot placed at 18 ℃ under the conditions of training so that the sprouts
