摘　　要：以地石榴为试验材料,采用腐殖土、河沙、(腐殖土+河沙)[(V(腐殖土)∶V(河沙)=1∶1]3种基质进行扦插试验,筛选出地石榴生扦插繁殖的最优扦插基质.结果表明,在腐殖土基质中,地石榴的生根率最高,达到90%,且根长、生根数量和平均叶片数等指标均显著高于其他两种基质;3种类型基质的扦插效果为腐殖土>(腐殖土+河沙)>河沙.此外考虑到成本等因素,因此确定腐殖土是地石榴扦插较为适宜的基质.Taking Ficustikoua as the test material,based on three types of substrate i. e. humus soil,river sand,humus soil and river sand 1∶ 1 mixed media [（ V（ humus soil） ∶ V（ river sand） = 1∶ 1],the cutting propagation experiment was carried out for filtering the best substrate. The results showed that the rooting rate was highest reaching 90% in the humus soil and the indexes of root length,root number and average blade number were significantly higher than those of the other two substrates. The effect of the three substrates was successively humus soil 〉 humus soil and river sand 〉river sand. After taking the costs into account,the humus soil was regarded as the best substrate.
