摘　　要：在企黑墨兰的花芽形成期即10月中下旬施用100 mg/L赤霉素(GA3)+50-100 mg/L6-苄氨基嘌呤(6-BA)具有更好的促进墨兰花葶生长,比对照提早10 d开花,花朵直径增大,花葶挺直美观;11月上旬喷放100 mg/L赤霉素(GA3)+50 mg/L 6-苄氨基嘌呤(6-BA),12月中旬对喷施激素处理后抽生的墨兰花葶喷施50 mg/L赤霉素(GA3)+50 mg/L吲哚乙酸(IAA)或50mg/L吲哚丁酸(IBA),均可促进提早7 d开花,12月中旬对自然抽生的花葶喷施50 mg/L赤霉素(GA3)+50 mg/L吲哚乙酸(IAA或吲哚丁酸(IBA),可促进墨兰提早5 d开花,而喷施50 mg/L赤霉素(GA3)50 mg/L赤霉素(GA3)+50 mg/L萘乙酸(NAA)后,花径生长不紧实、弯曲,小花花瓣有粘连现象。In mid to late October（flower-bud formation period）,spraying of 100 mg/L gibberellic acid（GA3） ＋ 50-100mg/L 6-benzylaminopurine（6-BA） on Cymbidium cinense could promote the scape growth,flowering 10 d earlier than the control,the flower diameter increase and the scape straight and beautiful; in early November,spraying of 100 mg/L gibberellic acid（GA3） ＋ 50 mg/L 6-benzylaminopurine（6-BA）,then in mid December,spraying of 50 mg/L gibberellin（GA3） ＋ 50 mg/L indole acetic acid（IAA） or 50 mg/L indole butyric acid（IBA）,on the scape which grew after hormone treatment could promote flowering 7 d earlier,but on the scape which grew naturally could promote flowering 5 d earlier; after spraying of 50mg/L gibberellic acid（GA3） ＋ 50mg/L naphthalene acetic acid（NAA）,the flower diameter was loose and curved,the flower was small and the petals were adhesive.
