Abstract：Toinvestigatetheoptimalapplicationstrategyofmicrobialagentsindrip-irigatedmuskmeloncultivation，the thick-skinned muskmeloncultivar Golden Years wasusedas test material tosystematicallevaluate thedose eectsof different microbial agent application rates（O，400，600， 800g per 667m2 Oon plant growth，rootarchitecture，and yield formation. The results showed that the 800g⋅667m⋅2 treatment（A3） significantly optimized the agronomic traits.At the seedlingandelongationstages，thestemthicknes，mainstemlength，leafnumber，andleafarea weresignificantlyincreased by 14.89% ， 14.29% 12.96% ， 17.91% ，and by 15.63% ， 34.39% ， 25.00% 9.11% ，respectively， compared to the control.

However， no significant difference was observed between the and A3 treatment.In conclusion，the "Junlin Tianxia"microbial agent， applied at 600-800g⋅667m-2 ，optimized root architecture and synergisticallyimproved yield， with 800g⋅667m-2 recommended as the optimal rate for balancing benefitsand stability.
