<br>栽培碗莲我们应先了解它的习性,它喜阳光,栽后每天至少要有6小时的直射,浇水适中,选择种子应该选择色泽新鲜,具有一个完整无损的顶芽。<br>养莲首先得浸泡莲子。莲子外壳非常坚硬,浸种前必须破壳,否则不易发芽。莲子的一头稍尖,另一头稍凹,要把稍凹的那一端夹破,<br>把浸种盘放到窗台前有阳光处催芽,水深以浸泡住种子,每天早晚各换水一次。<br>温度在30度的条件下,一般浸种催芽3天即可萌发,胚芽从破口处伸出,待根系形成便可入泥。<br>选一个无底孔容器,盆内加半盆塘泥,不要施肥。移栽时将小荷苗的细根按入泥中,以种子全部入泥为度,使叶片自由舒展于水面。<br>这样就将碗莲种植了,静待花开吧。<br>
