摘要：通过盆栽试验研究了植物促生菌(PGPB)对红树植物木榄幼苗的接种效应,供试菌为6种解磷菌(即B．amy, Vib,B．atr,Xan,B．Lic,P．M．)和5种固氮菌(即Au4,Phy,24S,JA4,cd),结果表明:(1)分别接种6种解磷菌株6个月后木榄幼苗的生长均得到了不同程度的促进,与对照相比,木榄苗高增加21．57％-9．54％,生物量增加27．49％ -20．32％,叶片的氮含量增加33．33％-1．35％,叶片的磷含量增加24．42％-2．04％;经差异显著性检验,B．amy 和Vib 2个菌种对木榄幼苗的促生效应比其它解磷菌株更明显;(2)分别接种5种固氮菌株6个月后木榄幼苗的生长均得到了促进,与对照相比,木榄幼苗的均高增加24．07％-10．22％,生物量增加32．36％-19．71％,叶片的氮含量增加23．39％-4．05％,叶片的磷含量增加32．79％-4．99％;差异显著性检验表明:Au4和Phy 2个菌种对木榄幼苗的促生效果比其它固氮菌更显著。
A pot experiment was conducted to investigate the growth-promoting effects of inoculation with plant growth-promoting bacteria on Bruguiera gymnorrhiza seedlings, including six phosphate solubilizing bacterial strains （ i. e. B. amy, Vib,B. atr,Xan,B. Lie,P. M. ） and five nitrogen-fixing bacterial strains （i. e. Au4,Phy,24S,JA4,cd）. Results showed that ： （ 1 ） After inoculated with the PSB for six months, the growth of the B. gymnorrhiza seedlings was accelerated significantly. The average height of B. gymnorrhiza seedlings was increased by 21.57% - 9.54% compared to those of controls, and the biomass was accordingly increased by 27.49% - 20.32%. The total N and P contents of inoculated seedling leaves were 33.33% - 1.35% and 24.42% - 2.04% respectively higher than those of controls ; （2） The test of significance of difference also indicated that the growth-promoting effects of B. amy and Vib were significantly higher than those of other PSBs ; （3） Six months after the inoculation of nitrogen-fixing bacterial strains, the average height of B. gymnorrhiza seedlings were increased by 24.07% - 10.22% , and the biomass was accordingly increased by 32.36% - 19.71%. The total N and P contents of inoculated seedling leaves were 23.39% - 4.05 % and 32.79 % - 4.99% respectively higher than those of controls; （4） The test of significance of difference also indicated that the growth-promoting effects of Au4 and Phy were significantly higher than those of other nitrogen-fixing bacterial strains.
