Abstract：UsingthepotatovarietyJizhangshu12asthetestmaterial，arandomizedblockdesignwasadoptedtoinvestigate the effects of three mulching methods [ridging with black plastic film（F），ridging with liquid film（Y） ，and ridging withoutmulch（L）]underdrip irrigation（W）andnon-irigated（D）conditionsonsoil moisture，temperature，potato growth，and yield.The yield increasing potential ofpotato under dripirigationconditions was analyzed，andthe optimal planting methodforpotato was determined.Theresultsshowed thatunder different planting methods，bothdripiigation and mulchingadvanced thephenological stagesof potato.Compared with tonon-irigatedconditions，dirpirigatin advancedthematurityperiod by6-9days.Compared withtraditional open fieldcultivation，black plastic filmand liquid film mulching promoted seedling emergence by 15 days and 2 days，respectively，and advanced maturity by 2-7 days. Comparedwithopenfieldcultivation，mulchinghadsignificant warmingandmoisture-retainingefects，andblackplastic filmhad the bestefect.Plantheight，stemdiameter，leafarea index，SPAD，tuber numberperplant，and yieldof potato wereall significantlypositivelycorelated.The planting method significantlyinfluenced potato growth.Compared with theDtreatment，the Wtreatmentsignificantly increased theaverage numberoflarge tubers，yield，and marketable tuber rateby 109.74% 138.47% ，and 145.95% ，respectively.Compared with theL treatment，theFandY treatments increased yield by 42.65% 67.28% and 11.34%-14.83% ，respectively.In conclusion，under drip irrigation，both black plastic film and liqud filmmulchinghadwarming，drought resistance，and moisture conservation，which could promote potatoseedling emergence and maturation.Among them，the combination of drip irigation with black plastic film mulching（WF） showedthe best performancein promoting plant growthandyield，making itasuitablecultivationmodelfor promotion in dry farming areas.
