不同基质对花叶常春藤扦插生根的影响

摘要

[ Objective]The research aimed to study the effects of several matrices on cutting rootage of Hedera nepalensis var. sinensis. [ Method]5 different kinds of cutting matrix formulation were designed to breed H. nepalensis var. sinensis root cuttings. Test formulation was measured at different matrix bulk density, moisture content and ventilation conditions,and the root length,root thickness,root weight, the content of chlorophyll and root activity and other data were determined too. [ Result ] The results showed that perlite + vermiculite + peat ( 1:1:1 ) was the optimal medium of H. nepalensis var. sinensis cutting propagation. [Conclusion]This research could provide scientific references for the cottage and reproduce study of H. nepalensis var. sinensis.%[目的]研究不同基质培养对花叶常春藤扦插生根的影响效应.[方法]设计5种不同的扦插基质配方时花叶常春藤进行扦插生根培养,测量不同基质配方下的容重、含水量和通气状况,以及插穗的根长、根粗、根重、叶绿体色素的含量、根系活力等数据.[结果]珍珠岩+蛭石+泥炭(1:1:1)的扦插基质对花叶常春藤的生根效应最好.[结论]该研究可为花叶常春藤的扦插繁殖研究提供一定理论参考.
