| 摘 要： | 利用前期从甘草等植物根际分离筛选的5株优良根际促生菌株RS1、RS5、RP1、Jm170和Jm92制成促生菌接种剂,在培养基条件下测定接种剂对甘草幼苗株高、地上生物量、地下生物量、根表面积、根体积、根平均直径和根长影响,通过主成分分析方法,筛选优良菌株。结果表明,5种促生菌剂对甘草生长均有不同程度的促进作用,促生效果综合排序:Jm92Jm170RS1RS5RP1。与对照相比,促生菌接种剂Jm92对甘草幼苗株高、地上生物量、地下生物量、根表面积及根体积增加达极显著水平(P0.01),分别增加32.8%、51.5%、202.3%、168.1%和180.3%,其次为Jm170,其以上指标分别增加27.1%、27.4%、164.0%、177.0%和121.2%。Jm92、Jm170、RS1在研制甘草根际专用肥中具有较大潜力。

| Abstract: | Five plant growth promoting rhizobacteria （PGPR）strains （RS1,RS5,RP1,Jm170,Jm92）isola-ted and screened from the rhizosphere of Radix glycyrrhizae were used to produce single inoculants and then its effect on the growth of R.glycyrrhizae was studies.The result indicated that the inoculants could increase the plant height,biomass,mean diameter and length of main root and the order of promotion effect of 5 strains was Jm 92＆gt;Jm170＆gt;RS1＆gt;RS5＆gt;RP1.Jm92 had a significant effect on plant height,aboveground biomass,root dry weight,root surface area,root volume and root length,which were enhanced by 32.8%,5 1.5%,202.3 %, 1 68.1% and 180.3% respectively compared to the control （P ＆lt; 0.01 ）.And which was followed by Jm170 （27.1%,27.4%,1 64.0%,177.0% and 121.2% respectively）.The inoculants （Jm92,Jm170,RS1）showed good promoting effects on the growth of R.glycyrrhizae and could be used as biofertilizer for the further study. |
