旱伞草四季均可繁殖,但以高温强光的夏季水插最好,不仅成活快,而且苗壮。温度低时则苗细弱。在30℃以上的强光条件下,6～7天可生根发芽,十多天后即可移栽。选粗壮的枝条做插条,最好是开过花的老熟枝条。在距枝顶端10～15厘米处剪断茎杆,剪下叶尖,留3～4厘米长的叶基,形成直径6～8厘米的圆盘,倒插于水中。叶片部分淹没在水面下,置于直射日光下。3～4天把水换去一部分,亦可不换(不换时易生绿苔,但无妨害)。为防止插条浮起,可在叶片上放些小卵石来固定。成活后,将茎杆全部 Umbrella grass four seasons can reproduce, but the best summer light water to heat the best, not only fast-growing, but also strong. The seedling is weak when the temperature is low. In the light conditions above 30 ℃, 6 to 7 days to germinate, transplanting more than ten days later. Choose thick branches to make cuttings, it is best to spend the old ripe branches. Cut the stem at 10-15 cm from the top of the shoot, cut the tip of the leaves and leave a leaf base of 3-4 cm in length to form a disk with a diameter of 6-8 cm and pour it into water. Part of the leaves submerged in the water, placed in direct sunlight. 3 to 4 days for the water to go some, can not change (do not change green moss easily, but without prejudice). In order to prevent floats, put some pebbles on the leaves to fix. After surviving, all the stalks
