12种常用耐盐植物的嫩枝扦插比较研究

Study of softwood cuttings cuttings of 12 kinds salt-toerant plants

以银条等12种绿化树种1a生嫩枝为试材,在8月中下旬进行嫩枝扦插,并调查其成活率、生根数量、根长,对比分析不同树种嫩枝扦插成活情况。结果表明:12种树种平均成活率达到69.57%,其中,鞑靼忍冬(Lonicera tatarica L.)、水蜡(Ligustrum obtusifolium Sieb)、连翘(Forsythia suspensa)的成活率最高,达到了90%以上,适合此时期嫩枝扦插;银条(Stachys sieboldii)、沙枣(Elaeagnus angustifolia)、杜梨(Pyrus betulaefolia)的成活率较低,为30%左右;成活率高低与植物平均根长有一定的相关性,与生根数量关系不明显。

Twelve greening plant species （for example purple leaf barberry） was used as test materials, and their cuttings were carried out in the softwood cuttings in late August to investigate the survival rate the number of rooting and root length. The results showed;the survival rate of lonicera tatarica L. Ligustrum obttuifolium Sieb and Forsythia suspensa reached more than 90%, which were suitable softwoof cuttings for this perriod;the survival rate of Stachys sieboldii Elaeagnus angustifolia and Pyrus betulaefolia reached about 30%. The survival rate had a certain correlation with the average length of mot,but was not associated with quantitative of root.
