摘　　要：应用Meta分析(Meta analysis)方法定量研究了接种丛枝菌根(Arbuscular Mycorrhizae,AM)真菌对车轴草属(Trifolium)植物生物量和营养吸收的影响。通过Web of Science数据库检索,共收集得到30篇原始文献,提取得到525个独立样本值。结果表明,接种AM真菌能够显著增加车轴草属植物的总生物量、地上生物量和地下生物量,促进其对氮、磷的吸收。不同的AM真菌种类以及车轴草种类均对接种效果有影响,其中珠状巨孢囊霉(Gigaspora margarita)对车轴草属植物的生物量的促进效应最大;埃及车轴草(T.alexandrinum)地上、地下生物量对接种AM真菌的响应最强。胁迫处理能显著降低AM真菌对地上、地下生物量的接种效应。随培养时间延长,AM真菌能够显著增加氮、钾、锌吸收的接种效应。Meta analysis was performed to quantify the effect of AM fungi inoculation on plant biomass and nutrient uptake of Trifolium plant. In this research,525 independent observations were extracted from 30 published scientific papers through database search of Web of Science. The results indicated that total biomass,shoot biomass and root biomass of Trifolium were significantly increased by AM fungi inoculum. Plant uptake of nitrogen and phosphorus was also promoted. Both AM fungi species and Trifolium species showed influence on the effect of inoculation. Gigaspora margarita inoculation showed the largest amount of biomass enhancement in Trifolium,while the shoot and root biomass of T. alexandrinum strongly responded to AM fungi inoculation. The stress treatment significantly reduced the effect size of plant shoot and root biomass. The effect size of plant N,K and Zn uptake was significantly positively correlated with incubation time.
