红木硬枝扦插试验研究

Study on the technology of hardwood cutting for Loropetalum chinense var.rubrum

用浓度５０ｍｇ／ｌ、１００ｍｇ／ｌ、１５０ｍｇ／ｌ的ＡＢＴ生根粉１号对红木三、四年生枝条进行浸泡处理，将处理好的枝条分别插于黄心土和珍珠岩基质中，６０ｄ后检查成活率，结果表明：以１００ｍｇ／ｌ的ＡＢＴ生根粉１号处理，插于黄心土基质中的红木枝条成活率最高，达５４７％；以１５０ｍｇ／ｌ的ＡＢＴ生根粉１号处理，插于珍珠岩基质中的红木枝条成活率最低，为２９４％；所有处理与对均有显著差异。

Cuttings from 3 or 4- year- old branches,treated with ABT solution of 50 mg/l,100mg/l and 150mg/l respectively,were planted in loess and perlite.After 60 days of planting,the survival rate of cuttings treated with 100mg/l and planted in loess was the highest(about 54.7%),While cuttings treated with 150mg/l ATP and planted in perlite had the lowest survival rate (29.4%).There were great differences between the treated and untreated cuttings.
