往年我插重瓣木槿,总是按照一般花木的扦插期,在5～9月进行,但多年未能成活。自从询问了《中国花卉盆景》,并在1999年9期26页《你问我答》栏目中得到解答后,我就改变了扦插时间。按照解答中的提示,我于今年清明木槿正在发芽时,剪取上年生枝条作插穗。因数量较多,我把它分成三组进行试验:第一组扎成小把,下端墩齐,头朝下埋入30厘米深的湿土中,覆土超出插条8厘米,按平压实,盖上塑料薄膜,保温保湿;第二组将剩下的直接插在盛有粗砂的浅苗盆中,盖上塑膜罩,置于温室的高床边,以保土温;第三组插于下半部盛看旧盆土(要排水好)、上半部铺盖粗砂的瓦盆内,盆径20厘米,每盆3
In previous years, I plugged the petals of hibiscus, always in accordance with the cutting of flowers and trees in general, from May to September, but failed to survive for many years.

Because of the larger number, I divided it into three groups to test: the first group tied into a small handle, the lower end of the mound, head buried in 30 cm deep wet soil, covering 8 cm beyond the cuttings, according to the compaction , Covered with plastic film, heat and moisture; the second group will be directly inserted in the sand filled shallow pots, covered with plastic cover, placed in the greenhouse of the high bed to protect the soil temperature; the third Group inserted in the lower half of Sheng old peat soil (to drain well), the upper half covered with grit pots, pot diameter 20 cm, each pot 3
