仙客来花期应该注意哪些问题?
仙客来花期应该注意哪些问题,仙客来进入盛花期,开花使水分大量蒸腾,盆土很容易失去水分,所以,在花期时仙客来严禁缺水。如果此时缺水,会使仙客来进入休眠状态,使花蕾的发育中断之后停止开花。仙客来若缺水会出现花茎倒伏、叶片脱水萎蔫,部分叶片甚至枯黄。家庭养花经常会出现此种现象。
冬季,由于提供了暖气,室温升高,蒸腾加剧,很容易造成由于浇水过多而使仙客来花梗和叶柄徒长软弱,而且易造成细菌性球根腐烂病;但如果浇水过少,则会造成叶片生长缓慢,使之发育不良。冬季,室内外温差较秋季更大,浇水宜在上午10~12时之间进行。因为冬天光照时间短、天气寒冷,仙客来每天要保证至少要3小时的光照,并且1周之内最少1次转动盆的方向,使仙客来植株受光均匀,以免仙客来由于具有趋光性,使株形长偏,影响观赏价值。
10月上、中旬移入室内充足阳光处培养,白天温度保持在18~20℃之问。为使仙客来花蕾繁茂,在现蕾期间给以充足的阳光,并增施2~3次磷液肥。现蕾后不可浇大水,以保持盆土湿润为宜,室内空气湿度不宜过高,湿度保持70%以上为佳。
过湿和高温引起花梗细长、花小色浅。经常转动花盆,以免植株长偏,对发叶过密的植株可适当稀疏,使营养集中,以利开花。仙客来的花连续不断地出现,开花后施肥不能中断,肥料宜施磷钾或复合肥,到盛花期停止追肥。开花后室内湿度不可过大,晴天中午要开窗通风,以免造成花朵枯萎及花梗腐烂,以上就是关于仙客来花期应该注意哪些问题的介绍。
