不同基质对3种柳树扦插繁殖的影响

Effects of Different Substrates on Cutting Propagation of Three Willow Trees

研究不同基质对白柳、金丝柳和乌柳3种柳扦插繁殖的影响。结果表明:不同扦插基质对白柳、金丝柳和乌柳插穗的存活率、新生枝条长度、平均根长、生根数和生物量都有显著性影响。3种柳树插穗在混合土基质下的存活率均达到95%以上,在沙土基质下存活率最低,但沙土对3种柳树插穗生根平均根长促进作用最为明显,3种柳树插穗在沙土基质下的生根情况相比较于其它两种基质更为优良,最高生根数可以达到15.2条。本试验通过研究不同基质下3种柳树的扦插繁殖情况,从而寻找3种柳树的较优的基质配置,为西藏白柳、金丝柳和乌柳的繁殖培育和产业化培育发展提供支撑。

To study the effects of different substrate treatments on the cutting propagation of white willows,golden willows,and black willows.This study used white willows,golden willows,and black willows as experimental materials,and conducted cutting propagation experiments using three substrates:field soil,sandy soil,and mixed soil.The results showed that different cutting media had significant effects on the length,survival rate,rooting number,average root length,and biomass of new branches of willow cuttings.Among them,the survival rates of the three willow cuttings reached over 95%in the mixed soil matrix,with the lowest survival rate in the sandy soil matrix;The rooting number of three willow cuttings in sandy soil is superior to the other two substrates,reaching a maximum of 15.2.By studying the cutting propagation of three kinds of willows under different substrates,the optimal cutting propagation substrates of three kinds of willows were selected,providing technical support for the propagation,cultivation and industrialization of XizangSalix alba L.Salix alba.and Salix cheilophila.
