Abstract：【ObjectivelAiming toaddressisuessuchas highabnormal yams rate，lowmechanization，and insufficient standardizationinthe traditionalcultivation modelof‘Shaxian glutinousyam'.Toexplore the shallow trough cultivation technologysuitablefor‘Shaxian glutinousyam’and to provide theoreticalfoundations and technicalsupportforachieving high-qualityand eficient productionofthisvariety.【Method】Basedonthe specifications and cultivation techniquesof shallwtroughs forplanting‘Shaxianglutinousyam’，evaluatedtheyieldandqualityindicatorsofyam，conducteda screning experimentonkeycultivation technology parameters forshallow troughs.Inaddition，theefectivenessof the optimal parameter combination was demonstrated and tested.【Result】Through single factor screening experiments with diferentparameters，theoptimal parametercombination forshallow trough cultivation technologyof‘Shaxian glutinous yam’was determined tobe：shalow trough diameter widthof14cm，depth of4cm，length of8Ocm，inclination angleof （204 25∘ ，soil cover thickness of 10cm ，yam planting depth of 10 cm，and planting density of 16OO plants per 667 m². Demonstrativeyieldtestsshowedthatcomparedtoconventionalcultivation，theaplicationof thistechnquesignificantly reduced the abnormal yams rate（to 10.6% ），increased the high-qualityyamsrate（to 76.4% ），andboosted theyield（with a yeild of 2165.3kgper667m2⋅ .【Conclusion】The application of shallow trough cultivation technology effectively lowers abnormal yams rate and enhances quality and yield for'Shaxian glutinous yam'.
