1、施肥种类与次数。观叶类花木在春、秋生长期只需施1-2次以氮肥为主的肥料(隔半月一次)。观赏花、果的花木在长枝叶阶段施1-2次以氮肥为主的肥料。从花芽分化到开花前宜施以磷肥为主的肥料。月季、茉莉、米兰等一年中开几次花的要酌情多施几次以磷肥为主的肥料(氮、磷肥料浓度要掌握好)。茶花、杜鹃等一年只开一次花的,花期忌施肥,以免花朵早谢。

2、施肥浓度。不同花卉对肥料浓度的适应各异。茉莉、月季、石榴等生长能力较强的花卉可浓些;兰花、茶花等吸肥较弱,为防止肥害,可采取薄肥勤施的方法,即3份肥7份水;大盆花木施肥可浓些;小盆栽小花则可淡些。

3、施肥方法。先松土后施肥,将颗粒肥料埋入盆土时避免与根系接触,或将颗粒融化后兑水浇灌,施肥后的次晨再浇一次水,有利于花木根系吸收。

4、花卉缺肥的症状。花卉缺肥时,叶片自下而上发黄(基部叶片老化除外),叶片边缘往下挂(施药浓度过大时叶片也发黄,但叶片边缘往上卷),可将腐熟鸡粪、豆饼加10倍清水稀释后施用。

5、花木缺水的症状。有些花木缺水时叶片也会发黄,如茶花、杜鹃等,可用1%硫酸亚铁2-3次,或用0.5千克食醋加水130-170升喷洒叶面,每隔10天喷一次,连续喷3-4次,可使叶片由黄变绿。

6、休眠期停肥。冬季室内花木进入休眠状态的,应停止施肥(早春开花的例外),君子兰、四季海棠等夏季进入休眠也停止施肥。此外,刚移栽的花木暂时不能施肥,待新根长出后再施肥。特别注意,未经腐熟的肥料不能施用,盆花换盆时要将基肥埋入盆土,避免与根系接触。

7、家庭自制化肥。居民家庭养花,肥源可自己配制,将无病的菜叶、瓜果皮、鱼骨、蛋壳、鱼内脏、霉变黄豆或淘米水等废弃物置于小缸内,加入一定量的水,用塑料薄膜封口扎紧(淘米水可灌入可乐瓶内),待充分发酵后舀取发酵汁兑水后使用,施用后可能有些气味,应通风。为适应家庭养花,花卉市场备有各种系列的化肥,如促花肥、叶片肥、全元素片肥(或颗粒状)、液体有机肥等,无气味且使用方便,养花爱好者可按需选购应用。

盆花施肥,应该根据不同花卉需肥的习性和不同生长与发育阶段的需要,温度、光照和季节变化,以及盆土的原有肥力和质地,做到适时、适量。

(1)施基肥基肥很重要,基肥充足可少施追肥。充分发酵后制成的有机肥适于作盆花的基肥。用法是将肥一至三成掺在培养土中,保持湿润,使肥与土充分融合,经过冬季或高温季节2~3个月后使用。可根据不同成分,分别作不同花卉的上盆、倒盆或换盆用土。蹄角类和禽毛作基肥,可在花卉上盆时直接放在盆底。豆饼等油粕肥和骨粉作基肥与粪肥用法相同,掺入培养土中用量为3%~5%。当年不换盆的花木,也可在花木休眠时,沿盆边开环形沟,施放一些发酵后的有机肥,然后盖上新的培养土,也可代替施基肥。无机肥如磷肥可用过磷酸钙和磷矿粉0.5%,氮肥可用硫酸铵0.2%、尿素0.1%,钾肥可用硫酸钾和氯化钾0.1%,两周前掺入培养土中作基肥。

(2)施追肥在花木生长季节中,施以稀薄液肥,以补基肥之不足叫施追肥。凡经发酵后的小便、豆饼水、鱼肠水、淘米水等1份原液,配以10~20倍水,或用尿素或磷酸二氢钾配成0.1%~0.2%的水溶液,每周施1~2次,立秋后每半月施1次。施追肥要掌握:营养生长期多施氮、钾肥,花芽形成期多施磷肥,施肥前一天要松土,施肥后的翌晨要浇水;开春后施,秋分后不施;雨前、晴天可施,雨后不施;气候干旱时施,梅雨季节不施;盆土干时施,盆土湿时不施,气候适宜生长旺盛多施,气候炎热生长停滞时不施,新栽、徒长、休眠时也不施;薄肥勤施,浓肥勿施;喜肥的菊花、茉莉,由淡到浓可多施,耐瘠薄的五针松等松柏类,宁淡勿要多施;花前花后施,盛花期不施;早晚可施,中午不施;壮苗可多施,弱苗要少施;不可过饥,不可过饱;不腐熟、不稀释不施。

(3)根外追肥用化肥溶液喷雾于叶片上下,以补根系施肥之不足叫根外追肥。由于肥分吸收增多,植株生长健壮,枝多叶绿,花繁艳丽,抗病力也增强,但不能代替土壤施肥。只能用易溶于水的尿素、硫酸铵、氯化钾、过磷酸钙、磷酸二氢钾等无机肥,在气温低、湿度大的天气,早晚进行。气温高容易干,吸收不了。深度以0.1%~0.2%为适宜,太淡肥效低,过浓难吸收。

回答(3):

尿素,复合肥,磷钾肥都可以.要少量多次.

回答(4):

每年三月底,将花搬到室外,松土,然后进行第一次施肥,如果20公分的花盆,可施15粒左右复合肥!30公分左右的花盆可施入25粒左右的复合肥!如果是10公分左右的花盆可施用5至8粒复合肥!施肥时可在离花根5厘米左右,挖几个深约三厘米的左右的小坑,将复合肥均匀埋入,浇透水即可!尿素肥料尽量少用或不用!
