摘　　要：通过2因素苗圃地试验设计方法,运用4种植物生长激素及4种不同浓度刺激插条来研究楚光冬青扦插生根效果;采用3种不同长度插条、3种不同基部径粗插条及3种不同扦插基质的正交试验设计L^(9)(3^(4))方案研究了楚光冬青扦插生根效果。结果表明:选用680×10^(-6)的吲哚丁酸(IBA)生根效果最好,生根率达到84.0%;选用长度16cm且基部径粗4mm的插条,扦插到砖红壤与珍珠岩等比混合的轻基质中时扦插效果最佳,生根率高达86.7%,单株生根数高达21.6条,单株平均生根长达9.8cm。The paper studied the rooting effect of IlexchuguangiiM.M.Lin cuttings using a 2-factor nursery ex-perimental design method,with four plant growth hormones and four different concentrations of high and low lev-els of stimulation for cuttings;at the same time,three different lengths of cuttings,three different basal diameter cuttings,and three different cutting substrates were used to study the rooting effect of Ilexchuguangii M.M.Lin cuttings using orthogonal experimental design L^(9)(3^(4))scheme.The experimental results show that using 680ppm indole-3-butyric acid(IBA)has the best rooting effect,with a rooting rate of 84.0%;when using a 16cm long cut-tings with a base diameter of 6mm and a mixture of red soil and perlite in an equal proportion,the cutting effect is the best,with a rooting rate of 86.7%and a single plant rooting of 21.6.The average root length of a single plant is 9.8cm.
