红花酢浆草的繁殖方法
红花酢浆草的繁殖方法,大花酢浆草是酢浆草科多年生草本植物,喜阳光充足、排水良好疏松肥沃的砂质壤土。大花酢浆草原产南非。同属常见的有另一种红花酢浆草,具有肉质半透明根,花呈淡玫瑰紫红色,直径约4厘米,原产南非,不耐寒。这两种酢浆草有一个共同的特性,其花和叶对光有敏感性——喜光,有光的白昼和晴天开放,晚上和阴雨天闭合。
酢浆草类的繁殖以分株为主,其鳞状根茎繁殖力很强,很容易萌发幼苗。春秋两季结合换盆移植分栽根茎,将休眠的鳞状根茎取出横向埋人土中,每盆3~4个。栽好后将盆放于阴处缓苗几天,即可成活。冬季在温室越冬。酢浆草果实成熟时容易开裂使种子散落,因此要掌握采种的时机。当果实由青转黄时及时采收,在室内摊开晾于纸上,取出种子。春秋盆播,保持土壤湿润。当温度为25℃左右时,7~10天发芽。春播苗当年开花,秋播者第二年开花。
栽培酢浆草盆土内要加入堆肥。鳞状根茎不能栽得过深,栽后浇透水,放在荫处,保持盆土湿润。生长期液肥2~3次。5~6月时红花酢浆草休眠,剪除残花枯叶,将盆倒置在通风隐蔽处。
红花酢浆草用于地被,多用种子繁殖,于3~4月播种,在25~30℃条件下7~10天发芽,当年秋季开花。小面积种植可在早春采根茎分株,按10~15厘米株距栽培,夏季即开花。红花酢浆草原产南美巴西,喜半阴与湿润环境,适宜沙质土壤栽培,温带地区可在露地越冬。因其生长迅速,繁殖力强,在生长期间宜保持土壤湿润,施2~3次全元素复合肥,以促进开花繁茂,花团锦簇。开花时期及时剪去残花,拔去杂草,减少养分消耗,增强观赏效果,以上就是关于红花酢浆草的繁殖方法的介绍。
