Effects of Arbuscular Mycorrhizal Fungi and Mycorrhizal Helper Bacteria Interaction on Tomato Growth

以番茄(Solanum lycopersicum L.)为试材,通过盆栽试验,设置接种AMF、接种MHB、双接种AMF和MHB处理,并以不接种处理为对照,研究不同接种方式对番茄生长及营养吸收的影响,明确AMF和MHB互作对番茄生长的影响,以期为菌根化技术及番茄的可持续发展提供参考依据。结果表明:与对照相比,单一接种AMF(Fm)处理、单一接种MHB(Ba)处理以及同时接种AMF和MHB(FB)处理的番茄幼苗植株地上部、地下部及全株鲜干质量均得到提高。与对照相比,接种AMF、MHB以及混合接种AMF和MHB,均提高了植株氮、磷、钾浓度和营养含量以及土壤速效钾、有效磷、硝态氨、铵态氮含量。其中,同时接种AMF和MHB(FB)处理,对番茄生长、植株养分及土壤状况等指标的促进作用最大,单一接种AMF(Fm)处理的促进效用次之,单一接种MHB(Ba)处理的促进作用相对较小。综上,接种AMF和MHB均在促进番茄生长方面发挥重要作用,双接种AMF与MHB对番茄生长的促进作用最大。

Taking tomato(Solanum lycopersicum L.)as the test material,a pot experiment was performed,AMF inoculation,MHB inoculation,double inoculation AMF and MHB was set up,and no inoculation treatment as the control.The effects of different inoculation methods on the growth and nutrient uptake of tomato were studied,the influence of AMF and MHB interaction on tomato growth were clarified,in order to provide reference for mycorrhizal technology and sustainable development of tomato.The results showed that compared with the control,the aboveground,underground and whole fresh dry weight of tomato seedlings with single AMF(Fm),single injection MHB(Ba)treatment and simultaneous injection of AMF and MHB(FB)treatment were increased.Compared with the control,inoculation with AMF,MHB separately and mixed inoculation with AMF and MHB increased the nitrogen,phosphorus and potassium concentrations and nutrient contents of plants,as well as soil available potassium,available phosphorus,nitrate ammonia and ammonium nitrogen.Among them,simultaneous inoculation with AMF and MHB(FB)treatment had the greatest promotion effect on tomato growth,plant nutrients and soil conditions,while single inoculation with AMF(Fm)treatment had the second most promotional effect,and single inoculation with MHB(Ba)treatment had relatively small promoting effect.In summary,both AMF and MHB inoculation played an important role in promoting tomato growth,and double inoculation of AMF and MHB had the greatest effect on tomato growth.
