摘　　要：为了筛选对大花高代具有矮化效应的叶面肥,采用多效唑、比久、通丰、试验1号和试验2号5种叶面肥对不同播期的两组大花高代苗进行喷施,研究不同叶面肥处理对大花高代苗生长状况的影响。结果表明,多效唑、比久均能促使大花高代节间缩短、植株矮化,但以叶面喷施多效唑的效果最为明显,而通丰、试验1号和试验2号对大花高代没有矮化效应。该研究结果可直接用于大花高代的矮化栽培。The research aimed to screen leaf fertilizers that had dwarfting effects on Godetia grandiflora lindl.2 groups of G.grandiflora seedlings with different sowing dates were sprayed with 5 kinds of leaf fertilizers such as paclobutrazol,daminozide,Tongfeng,Shiyan 1 and Shiyan 2.The effects of different leaf fertilizers on the growth of G.grandiflora seedlings were investigated.Both paclobutrazol and daminozide could shorten the internodes and dwarf the plant of G.grandiflora,with the effects of leaf spraying with paclobutrazol being the most significant.But Tongfeng,Shiyan 1and Shiyan 2 all had no dwarfting effects on G.grandiflora.The results of the research could be directly used in dwarfing cultivation of G.grandiflora.
