摘　　要：为筛选适合大叶女贞容器苗生长的基质与容器,研究了7种基质配方与2种育苗容器对大叶女贞容器苗叶片生理特性的影响。结果表明:基质配方P2(泥炭∶蛭石=1∶1)与P5(泥炭∶蛭石∶珍珠岩=1∶1∶1)处理大叶女贞叶片叶绿素含量、相对电导率、净光合速率、过氧化物酶(POD)活性及过氧化氢酶(CAT)活性均优于其他基质配方,可作为大叶女贞容器育苗的优良基质配方;对2种育苗容器而言,无纺布容器苗在叶绿素含量和净光合速率2个方面明显高于塑料袋容器,其他指标差异不明显,基于无纺布容器苗根系发达、移栽成活率高且无纺布可自动降解等优点,确定无纺布容器是适合大叶女贞容器育苗的理想容器类型。In order to screen media and containers for Ligustrum lucidum container seedlings,the physiological characteristics of container seedlings leaves were investigated to estimate the effects of seven media and two containers on L.lucidum,with a traditional medium served as the control. The results showed that the chlorophyll content,relative electrical conductivity,photosynthetic rate,POD activity and CAT activity of the container seedlings in media No.2 （peat∶vermiculite=1∶1）and No.5（peat∶vermiculite∶perlite=1∶1∶1）were significantly superior to the others,and the media No.2 and 5 were better as the container nursery of L.lucidum.The chlorophyll content and net photosynthetic rate of the non-woven container seedlings were significantly higher than the plastic container ones,and there was no significant difference in the other physiological characteristics.Non-woven container seedlings had developed root system and high transplanting survival rate,and non-woven was a kind of degradable material.Therefore non-woven container was ideal for L.lucidum container seedlings.
