该试验采用随机区组试验设计方法,将组合的促生菌接种到桉树苗木,通过苗期及造林试验,筛选出一批促生效果较优的组合菌株.结果分析表明:桉树接种组合促生菌,其促生效果达显著性水平.林龄7月龄及21月龄时,各接种处理组相对于对照处理组树高增长分别达16.35％～ 40.55％和4.47％～ 11.07％;地径增长分别达13.05％ ～24.99％和5.03％ ～ 18.50％.组合促生菌株相对于单一 菌株表现出较好的接种促生效果,且采自桉树林地的菌株接种促生效果要优于采自非桉树(罗汉松)林地的菌株.%The combination of PGPR was inoculated into Eucalyptus for seedling and afforestation test with randomized block design, a number of combination strains which have good growth-promoting effect had been screened out. The test results showed that Eucalyptus inoculated with combination of PGPR showed a significantly growth-promoting effect. The tree height of inoculation group was respectively 16. 35% -40. 55% and 4.47% -11.07% higher than the control group at the seventh and 21st month, while the basal diameter was respectively 13.05% -24.99% and 5.03% -18.50% higher than the control group. The compound PGPR, in comparison with single PGPR, showed better growth-promoting effect, and the growth-promoting effect of strains collected from Eucalyputs forest was better than that collected from non-Eucalyputs (Podocarpus macro-phyllus) woodland.
