| 摘 要： | 以丛枝菌根真菌（Arbuscular Mycorrhizal Fungi,AMF）单一菌剂Glomus versiforme(AM-1)和混合菌剂Glomus spp.(AM-2)分别对番茄进行菌根化育苗试验，分析不同基质和接种时期对菌根形成率的影响。结果表明，以果园土与蛭石体积比为3∶1的混合物为基质，菌根形成率最高；播种期和一叶期接种对菌根化效果的影响不显著，二叶期接种的菌根形成率显著降低。温室盆栽条件下，菌根化程度高的番茄苗具有较好的延缓青枯病发生的能力，但后期病情仍会加重。

| Abstract: | In pot experiments,tomato seedlings were inoculated with arbuscular mycorrhizal fungi Glomus versiforme(AM-1)and Glomus spp.(AM-2).The effects to mycorrhizal root percentage which under different substrate conditions or at different inoculation time were analyzed,respectively.The results indicated that the highest percent of micorrhizal root could be obtained by substrate of vermiculite and soil mixture at the ratio of 1∶3 in volume.No significant difference of mycorrhizal root percent was observed between inoculating at seeding stage and at one leaf stage,but a significant decrease of mycorrhizal root percentage was present when inoculating at two leaf stage.In pot experiment under greenhouse conditions,tomato seedlings with higher percentage of mycorrhizal root could delay the occurrence of tomato bacterial wilt(Ralstonia solanacearum).but at the later stage,the state of illness would become aggravate. |
