报春花的种植方法
报春花的种植方法,报春花要求中性与微酸性的肥沃砂质壤土,喜冷凉湿润的气候环境。生长开花适温10~15℃。肥料宜加硫酸亚铁和充分腐熟的含有氮磷钾的肥水,生长期每10~15天追肥1次。
报春花在夏季高温期呈半休眠状态,要少浇水,放在凉爽、通风良好的地方。否则,叶片容易黄化。越冬在0℃以上的室内进行,5℃以上时,抽葶开花。开花后应及时剪除残梗,有利于再次抽葶开花。
报春花通常用播种方法进行繁殖。从播种到开花约需230天左右。为了提前开花,种子成熟后及时播种。播种土用过筛的、富含腐殖质的砂质壤土为佳。播种后,用细土覆上1~2毫米,以不见种子为度。浸透盆土后,覆盖塑料薄膜或玻璃,在15~21℃的气温条件下,保持湿润,约10天出苗,15天出齐,然后去掉覆盖物,放在有光照和通风良好处。2~3片叶时分植,5~6叶片时上盆,以上就是关于报春花的种植方法的介绍。
