荷花花期如何改变
荷花花期如何改变,荷花的花期为6~9月,花色有红、粉、白、复色等,花型有单瓣、半重瓣及重瓣之分。同一品种的荷花,栽植迟早不同,从栽种到开花的时间亦有差异。荷花生长发育的适温为22~30℃,但温度高从栽种到开花需时短,温度低需时长。如佛座莲若于3月28日栽植,6月3日开花,需时66天;而5月31日栽植,则7月15日开花,只需45天。光照强,生长快,开花早;短光照则生长慢,开花迟。
根据花期迟早和外界因素的关系,可以采取相应的措施,使花期提早或推迟。具体方法有两种:
(1)二次翻缸加温寿星桃、娇容三变等品种,新藕成熟早,于7月中旬前后栽植新藕,可望“十一”赏花;晚花品种,9月初新藕一成,如栽于台适的温室,荷花可连续生长,于冬季开花。
(2)推迟栽种时间将种藕假植,经常疏摘种藕上的立叶和花蕾,抑制生长。至7月下旬再行栽植,也可在国庆节赏花,以上就是关于荷花花期如何改变的介绍。
