摘　　要：以1a生草本花卉桂圆菊为试验材料,采用盆栽试验方法,研究不同比例蚯蚓粪和沙壤土作为混合栽培基质对桂圆菊的株高、冠幅、花序数、花序直径和开花时间等特性的影响。结果表明:以蚯蚓粪和沙壤土作为混合栽培基质栽培桂圆菊,可以促进桂圆菊的生长发育,明显增加株高、花序数,增大冠幅、花序直径,提早开花时间等;混合栽培基质中蚯蚓粪和沙壤土比例为1:1时,对桂圆菊的栽培效果最好。Taking a herbaceous Spilanthes oleracea as experiment material,using the potted experiment,taking different proportion of vermicompost and sandy loam as a mixed-culture substrate,the effect of its on plant height,crown,inflorescence number,inflorescence diameter,and flowering time characteristics of Spilantheso leracea were studied.The results showed that vermicompost and sandy loam as a mixed-substrate cultivation of Spilanthes oleracea,Spilanthes oleraceacan promote the growth and development,a marked increase in plant height,inflorescence number,increased crown,inflorescence diameter,early flowering time.Mixed culture medium of vermicompost and sandy loam in the ratio of 1：1,the right Spilanthes oleraceacultivation was the best results.
