生石花繁殖方法
生石花繁殖方法,生石花多用种子繁殖。花谢后不要剪去残花,让其结实。秋末冬初种子成熟。即可播种,但温度不能低于18℃。若温度达不到,可于次年5月份播种。生石花种子细小,基质排水性要好,盆底放一层粗沙,上面再铺消毒面沙。播种时用拇指和食指捏一点,撒在盆面,再捏些面沙薄薄盖一层。
用浸盆法给水,盖上玻璃或透明薄膜保湿,让其充分见光,一般30天左右可出苗。出苗后去掉玻璃、薄膜,放室内阳光处,注意通风,仍用浸盆法给水。当苗株快挤满盆面时,用小竹片挖取植株移栽,盆内也应放湿润面沙。先不浇水,放阴处,1周左右再用浸盆法给水。
秋后再移栽1次,以后随着植株逐渐长大,多次分苗另栽,一般3~4年后畏日可开花。开花后的成年植株,春季能从缝中长出一对新叶,可更鞒植株;爱季可从缝中长出2~3株幼株,待老叶干枯后,可分栽另种。
