四季秋海棠怎么过冬?
四季秋海棠怎么过冬?四季秋海棠性喜温暖怕冻,20℃左右气温最适合它生长。深秋以后,气温逐渐降低,生长受到抑制,可于11月上、中旬人室,置窗前向阳处培育,室温在15℃以上时,仍继续生长,开花不绝。12月份入冬后,进入休眠状态,新枝绿叶不发,花朵也很稀少。
当室温低于5℃时,夜间应将盆移至离窗VI较远处,防止玻璃上寒气和窗缝中冷风侵袭而受冻,翌日再移至窗口有阳光处。当窗温降低至0℃时,可用透明塑料袋连盆罩住,在盆口处扎好以保暖。当袋内有较多水珠时,可另换新袋,借此换气和防止叶片腐烂。不能将盆置于厨房或取暖炉边,否则温度过高,叶片会受熏烤灼伤,影响休眠。
在室内越冬时,因气温低、蒸发少,浇水要慎重,盆内心土干了才能浇水,做到干透浇透,一般10天左右才浇水1次。休眠期中不能施肥,当植株叶面积尘多时,可在风和日丽的晴天,配合浇水冲洗叶面。3月份的晴天,气温升高,开窗通风,防止过堂风吹袭受冻。到4月初,夜间气温不低于10℃时,可移盆于阳台莳养,以上就是关于四季秋海棠怎么过冬的介绍。
