南方荚蒾扦插繁殖试验

摘要

Viburnum fordiae Hance branches for the cuttings in different cutting substrates (Woodland yellow sub-soil∶river sand =3∶2,Woodland yellow subsoil∶slag soil = 3∶2,garden soil),different parts of the branches (base,middle,and top),different concentrations of ABT1 rooting agent (100mg/kg,200mg/kg,300mg/kg,)cut-ting propagation experiment,the results show:that the substratum in Woodland yellow subsoil∶river sand =3∶2 has the highest cutting survival rate,by 79.7%;Cuttings to spike the highest survival rate in central branches,by 79.8%;ABT1 rooting agent concentration to 200mg/kg the most appropriate,cutting survival rate of by 79.7%.%试验采用南方荚蒾枝条为插穗进行不同扦插基质(林地黄心土∶河沙=3∶2、林地黄心土∶炉渣土=3∶2、园土)、枝条不同部位(基段、中段、稍段)、ABT1生根剂不同浓度(100mg/kg、200 mg/kg、300 mg/kg)的扦插繁殖试验，结果表明：扦插基质以林地黄心土∶河沙=3∶2的扦插成活率最高，达79.7%；插穗以枝条中部的穗条成活率最高，达79.8%；ABT1生根剂浓度以200 mg/kg最适宜，扦插成活率达79.7%。
