家里的花在长叶子的时候可以施含氮较高的花肥,比如:尿素、小便、复合肥。因氮能促进叶片的生长。在开花期间可以施含磷、钾较高的复合肥或叶面喷施0.2%的磷酸二氢钾水溶液有利开花,结果。施肥时要按使用量进行,挖穴埋施或喷施。

花卉施肥较复杂,一般掌握的原则是:施肥量宜少量多次;无机化肥不能撒施或接触茎基部;有机肥要经堆沤腐熟再使用;夏日高温高湿天气植株生长旺盛时宜多施;冬季低温光照弱植株生长缓慢时宜少施;大雨过后或植株叶色黄绿暗淡缺肥时要及时补施等等,不同情况的施肥法如下:
1、 花卉基肥——大面积地栽花卉或营养育苗床多采用经腐熟过的有机肥。基肥施用量1500—3000斤/亩,若改用饼肥、骨粉、牲畜干粪等则用量为100—200斤/亩,或同时渗施生物肥20—40斤/亩,整地时均匀翻入土中,数日后便可种植。营养苗床多采用吸附性强的介质如泥炭等,植苗前加入适量的营养元素,让其充分吸附后再种植,也可同时加入0.001—1ppm的锰、铁、锌、硼、铜、钼微量元素。
2、 盆栽花卉追肥——盆栽花卉因盆内介质容量有限需要随时补充多种营养。对已返青出新叶的苗株,即应开始追肥,追肥量视盆的大小,每盆每次施复合肥40—60粒(进口复合肥);对已生长健壮的苗株,每盆每次施100—120粒外,每月施2次,另配合喷淋配方液肥5—8次;如遇大雨过后还应补施追肥一次。追肥应施在盆的周边,尽量远离茎基部,尤其不能让肥粒落入有轮生叶(如龙血树类、凤梨类等)的中心。如需要催花可加喷0.2%的磷酸二氢钾,加速花芽发育健壮,一般3—5天喷一次。

不同种类的盆栽花卉的追肥法:
① 球根、肉质类花卉追肥——因球根和肉质茎可储存养份,且根系较少,其追肥量可按正常量减半。由于它们对氮、钾、钙要求较高,使用配方液肥时常以硝酸钾、硝酸钙为主配合用。
② 须根类花卉追肥——此类花要求栽种在疏松的介质中,如西洋杜鹃、观赏凤梨等。追肥要求少量多次,追肥量为正常量的1/5—1/4,即每盆每次施复合肥15—30粒便可。
③ 大叶类型阴生观叶花卉追肥——此花生长迅速,根系发达,需肥量多,如天南星科的万年青等。追肥量除按正常量每月2次,每次施复合肥100—120粒,另加喷配方液肥5—8次。
④ 盆景追肥——盆景施肥的特点是数量要少,肥效要长。一般用缓效有机肥如骨粉、饼肥等为主体,配入缓慢释放的脲甲醛、磷矿粉等和少量速效肥配制而成。如无现成的盆景专用肥,可用市售花肥辘入橄榄油或塑膜包裹液处理后,就能达到持续、长效,将肥料浅埋于盆边基质下便可。大面积生产的盆景可采用配方液肥喷淋法,每3—5天喷淋一次,相间喷水洗盐一次便可。
在盆土不能维持花卉正常生长时,会出现叶片发黄、枝条细弱、花稀果小等状况,这样就需要施肥。但施肥须根据花卉品种、习性、施肥目的、所缺元素来决定肥料的种类、份量、次数、和施肥方法。
家庭栽花,可分庭植(即露地栽植)和盆栽两种,施肥也应有所区别。庭植虽与田野有别,但是地温高,范围大,吸水、吸肥方便,所以施肥、浇水次数可以少些,肥料稍浓些一时也不造成肥害。而盆栽则不同,由于环境得局限性,一方面不能缺肥以防缺素症;另一方面又要防止肥量过大,对植株产生肥害,影响植株正常生长。
植物习性也有喜肥耐瘠之分,如柑橘、南天竹、石榴、令箭荷花等喜肥植物应较多施肥;而杜鹃、黑松、无针松等耐瘠植物应施薄肥。杜鹃由于根须细,吸肥力弱,肥多反而受害,肥少则影响开花。
施肥,首先要懂得肥料得种类及其功用。花卉的基本养分,是氮、磷、钾三要素:
1、氮肥:能促使枝叶繁茂,提高着花率。常见的氮肥有人粪尿、硫酸铵等。
2、磷肥:能使花色鲜艳,结实饱满。常见的磷肥有米糠、鱼鳞、骨粉、鸡粪、过磷酸钙等。
3、钾肥:能使根系长得健壮,增强花卉对病虫害和寒、热的抵抗力,还能增加花卉的香味。常见的钾肥有稻草灰、草木灰、硫酸钾等 。
