通过4因子2水平正交试验设计,研究不同生根促进剂(A)、不同浓度(B)处理不同生长期的降香黄檀插穗(C)及不同插穗直径(D)对降香黄檀扦插生根率的影响差异;比较了8种不同配方的轻基质网袋容器(E)对降香黄檀扦插生根率、生根数和生根长的影响差异.结果表明:生根促进剂采用ABT-1#(A1)+浓度采用600mg/kg(B2)+插穗生长期12个月(C2)+插穗直径1.0～1.3cm(D1),即A1B2C2D1组合最好,扦插生根率最高,达到86.7%;8种不同配方的轻基质网袋容器扦插对比试验中,以泥炭∶木屑∶树皮∶红心土＝3∶3∶3∶1(E8)最佳,扦插生根率高且生根数多.“,”Through 4 factor 2 horizontal orthogonal test design,the research was conducted on different root growth promoters (A),different densities (B) different vegetal periods (C) and cuttings with different diameters (D) and the influence on cutting root growth (E).The result indicated that root growth promoter to use ABT-1# (A1) + the density to use 600mg/kg (B2) + cutting growth period with 12 months (C2) + cutting diameters with 1.0～1.3cm (D1),namely A1B2C2D1 combination is best.The high cutting growth rate is achieved,reaching 86.7%.The comparative test of the container cuttings with 8 different types of light media shows that the proportion of pent soil,sawdust,bark and red subsoie is 3∶3∶3∶1(E0) which proves to be the best.Cutting root growth rate is high with large numbers of roots.
