分别对丹桂带腋叶片扦插育苗进行了14种育苗基质、4种龄期带腋叶片、8种处理插穗药液、4种插穗入土深度的单因素试验，分别得出最佳单因素为生红壤土＋20％河沙作苗床、半年生以内的带腋叶片为插穗、用25 mg/kg高锰酸钾浸5 min＋100 mg/kg（ ABT1＋IAA）浸20 min处理插穗、带腋叶片入土1/3。组合各最佳单因素进行育苗，插穗生根率100％，插穗成苗率98．10％。应用该技术累计育成丹桂苗458．20万株，在新余市营造示范林1907 hm2，向社会提供了大批绿化所需的丹桂树，经济与社会效益显著。
分彆對丹桂帶腋葉片扢插育苗進行瞭14種育苗基質、4種齡期帶腋葉片、8種處理插穗藥液、4種插穗入土深度的單因素試驗，分彆得齣最佳單因素為生紅壤土＋20％河沙作苗床、半年生以內的帶腋葉片為插穗、用25 mg/kg高錳痠鉀浸5 min＋100 mg/kg（ ABT1＋IAA）浸20 min處理插穗、帶腋葉片入土1/3。組閤各最佳單因素進行育苗，插穗生根率100％，插穗成苗率98．10％。應用該技術纍計育成丹桂苗458．20萬株，在新餘市營造示範林1907 hm2，嚮社會提供瞭大批綠化所需的丹桂樹，經濟與社會效益顯著。

We have carried out single -factor experiment for the cutting breeding of orange osmanthus with axillary leaves , and this experiment designed 14 kinds of substrates for breeding , 4 different ages of axillary leaves , 8 kinds of liquid for treating the cut-tings, 4 depths of cutting in soil.The best single factors were obtained as follows:raw red soil plus 20%river sand as seedbed;ax-illary leaves at the age of less than half year as cuttings;soaking the cuttings into 25 mg/kg potassium permanganate for 5 min and then into 100 mg/kg ( ABT1+IAA) for 20 min; burying the 1/3 of axillary leaves into the soil .Then we conducted the cutting breeding of orange osmanthus under the combined conditions of all best single factors , the rooting rate of the cuttings was 100%, and their grownup seedling rate reached 98.10%.Through the application of this technology , 4582000 orange osmanthus seedlings have been bred , 1907 hm2 demonstrative forest has been constructed in Xinyu city , and significant economic and social benefits have been acquired .
