凤仙花的栽培方法
凤仙花的栽培方法,凤仙花又名金凤花,花朵如飞凤,夏日盛开,生机勃勃,是爱好者喜爱的花卉。凤仙花属于凤仙花科,原产印度,为一年生草本。喜热不耐寒冷,对土壤适应性强,地不择干湿,移不择时间,且病虫害少,在向阳排水良好的疏松土壤中种植更是叶茂花繁。种子一旦成熟,即开裂弹出,所以又叫它“急性籽”。
凤仙花用种子播种繁殖,于春季3~4月播于露地用床,或直播于花坛,亦可在屋前房后栽植。种于发芽整齐,幼苗生长迅速,出苗后若幼苗过密,可陆续间苗。苗高在7~8厘米时,约在6月中旬就可定植,株距为30~40厘米,若植于盆内,可用盆径20厘米的泥盆,起掘后带泥垛上盆,培养土可用国土加10%砻糠灰混合即可,定植后每隔10~15天施稀薄液肥1次,以腐熟饼肥水或人粪尿均可,肥水比例为3:7,若喷1~2次0.2%二氢钾,则更是花繁叶茂。夏日温度高,土壤干燥,需及时浇水,早晨浇足,晚上若盆干旱再少许补给一下,过干或过湿易引起落叶而减低观赏价值。
种子成熟期,应选植株强健、花色艳丽的留种。要坚持选优,否则易退化。蒴果成熟后容易开裂,故在果皮发白时,用手指轻压,若已能开裂,当即收下种子。
凤仙花怕积水、久湿和通风不良,以上就是关于凤仙花的栽培方法的介绍。
