虎刺梅生性特别,生长慢,每年只长10厘米左右,但寿命长,盆栽能活30年以上。花期长,如光照温度得宜,可全年开放。
虎刺梅枝条不易分枝,会长得很长,开花少,姿态凌乱,影响观赏,故每年必须及时修剪,使多发新枝,多开花,一般枝条在剪口后,可生出两个新枝。
虎刺梅根系发达,生长旺盛,可作嫁接仙人指、蟹爪兰的砧木,但属浅根系,横走很远,根毛却不多。
虎刺梅性喜温暖,不耐寒,白昼22℃左右,夜间15℃左右生长最好,在温室保持15℃至20℃,可终年开花不绝,如下降至10℃则落叶转入半休眠状态,至次春吐露新叶,继续开花。
虎刺梅喜光,花前阳光越充足,花越鲜艳夺目,经久不谢,光照不足,则花色暗淡,长期置阴处,则不开花。另须注意保持空气流通。
虎刺梅可用培养土垫蹄角片作底肥,生长期每隔半月施肥一次,立秋后停止施肥,忌用带油脂的肥料,防根腐烂。
虎刺梅耐旱,春秋两季浇水要见干见湿。夏季可每天浇水一次,雨季防渍水,冬季不干不浇水,盆内不宜长期湿润;花期也要控制水分,水大易引起落花烂根。
春末夏初,5月至7月间,扦插虎刺梅最易成活,选粗壮枝条,长约10厘米至15厘米左右,擦干切口处流出的白浆,涂以草木灰,在阴凉处晾干2日至3日,使伤口处干燥后再插入素沙之中,浇透水,以后少浇,待盆土稍干时再浇,约经过50天至60天即能生根
虎刺梅
一、形态特征:
虎刺梅是大戟科藤蔓状多刺植物,
原产于马达加斯加,是受欢迎的室内植物,茎稍攀缘性,分枝,可长达2米余。茎上有灰色粗刺,叶卵形,老叶脱落。花小,成对著生成小簇,各花簇又聚成二歧聚伞花序。外侧有两枚淡红色苞片,花小。苞片有黄色,也有深红色。亦称基督刺、虎刺、麒麟花、老虎簕。
二、生长习性:
喜温暖、湿润和阳光充足的环境。稍耐阴,耐高温,较耐旱,不耐寒。以疏松、排水良好的腐叶土为最好。若冬季温度较低时,有短期休眠现象。
三、叶子发黄的原因:
虎刺梅是常见的室内植物,虎刺梅不宜放在室内养护,因为它具有致癌的危害,但还是有一些花友喜欢将其养在室内,虎刺梅虽然枝条带刺、有毒,但开花很好看,这也是花友们放在室内养的原因,但一定要谨慎养殖。在养殖过程中,有的花友会遇到虎刺梅叶子发黄的情况,遇到此类现象先不要着急,先找到虎刺梅叶子发黄的原因。下面列举了一些常见的原因,可以可以对照参考。
1、秋末,虎刺梅在进入盛花期的同时,也即将进入冬季休眠期,所以有叶子发黄的情况是正常的,即使叶子掉光了,春天也会重新萌发新叶。
2、在冬季气温低于10度以下的地区,虎刺梅的老叶会脱落,仅剩留顶部嫩叶;气温更低时,叶片会全部干枯、脱落。
因为冬季是虎刺梅的花期,所以为了植株多开花,应当保持盆土略微湿润,不过,这样也会加速叶片的枯黄、脱落。在花期,应当增加虎刺梅的阳光直射量。
3、如果你更看重植株的叶片保存,那么,建议你冬季要将植株摆放在室内温度高于15度的地方,少浇水,让盆土尽量干燥;不要施肥。这样,植株在休眠的状态中,生长放缓,叶片也会相对稳定。只不过,这样做,会影响开花的质量。
4、其实,虎刺梅很皮实,你可以顺应它的自然生长规律,在秋冬季节,让它自然黄叶、落叶,尽量多开花。到了明年春暖时节,它会更加枝繁叶茂的。
5、人为的浇水过多,如果温度光照都合适,花友可以看看是不是近期浇水量很多,导致了积水。
