雏菊的繁殖方法介绍

#雏菊 是菊科植物的一种,一般在春季开花,现在有很多花友都会将其盆栽,但雏菊的寿命并不长,所以可以通过分株、扦插等方法繁殖。小编就为你介绍一下在雏菊繁殖过程中需要注意的问题。

一、种子繁殖
南方多在秋季8-9月份播种,也可春播,但往往夏季生长不良。北方多在春季播种,也可秋播,但在冬季花苗需移入温室进行栽培管理。由于雏菊的种子比较小,通常采取撒播的方式。但播种苗往往不能保持母株的特征。播种前施足腐熟的有机肥为基肥,并深翻细耙,做成平畦。用细沙混匀种子撒播,上覆盖细土厚0.5厘米左右,播种后覆盖遮阳网并浇透水。播后保持温度在28℃左右,在早春阴冷多雨时覆盖塑料薄膜,以保持土壤湿度和温度。浇水宜细喷,以防土壤表层板结。约10天后小苗出土,揭去遮阳网或塑料薄膜,在幼苗具2~3片时即可移栽到大田。菊花菜可直播,在我国南方2月即可播种,在北方寒冷地区于4月上旬方可播种,每亩用种量约0.2千克。

二、分株繁殖



由于实生苗变异较大,对于一些优良品种可采用分株法繁殖,但生长势不如实生苗,且结实差。在3月中下旬可将老茬菊花菜挖出,露出根颈部,将已有根系的侧芽连同老根切下,移植到大田中。分株繁殖在萌发新梢时进行较适宜。

三、扦插繁殖

在整个生长季节均可进行扦插繁殖,以4~6月扦插的成活率最高。苗床最好用新土混入经堆沤腐熟的有机肥。剪取具3~5个节位、长8~10厘米的枝条,摘除基部叶片,入土深度为插条长的1/3~1/2。扦插后保持功床湿润,忌涝渍,高温季节需遮阴,而在温度较低时可搭塑料薄膜拱棚保温保湿。一般15天后可移植到大田。
