摘　　要：用3种基质淡水盆栽1 a龄红树植物桐花树(Aegiceras corniculatum)1年,分别以人工海水(8 g/kg)为对照,研究不同基质的淡水盆栽对桐花树生理生态的影响.结果表明:淡水盆栽对桐花树的生理生态虽有显著影响,但仍能正常生长,这可能是因为桐花树具有较强的光合作用和根系活力等生理特性,基质配比为m(塘泥)∶m(麦糠)=1∶0和m(塘泥)∶m(麦糠)=2∶1较适合盆栽桐花树.Using artificial sea water（8 g/kg） as a control,three kinds of substrates was used to pot-cultivate 1-year-old mangrove of Aegiceras corniculatum for one year in fresh water condition to investigate the effect of cultivation under fresh water condition on the eco-physiological characteristics of Aegiceras corniculatum in different substrates.Results of this study indicate that,though there is a significant effect on eco-physiological characteristics when cultivated in different substrates,Aegiceras corniculatum can grow normally under fresh water condition,as the 1-year-old Aegiceras corniculatum showed physiological characteristics of strong photosynthesis and root activities.The substrates of pond scum bran =1∶0 and pond scum bran=2∶1 were suitable for the plant cultivation under fresh water condition.
