Abstract：Toexploretheefectsofdiferentrowratiosinmaize/autumpotatointercroppingonthegrowthofautumnpotatonthe central double cropping system zone.this experiment set up seven row ratios：T1（maize/potato =1/1 ），T2（maize/potato 1/2），T3 （maize/poato/），4（epat/）zeota/2）（pota/3dzeota/4）.l calcharacteristicsandyieldofpotatoandedaphicconditionunderdiferentrowratioswereanalyzedandcompared.Theresults showed that 712 increased the yield compared toother treatments;Theplant heightof potatodecreased withthedecreaseoftherowratio.Therewasnosignificantdiferenceinsoilmoisturecontentamongthetreatments;ThedailysoiltmperatureinTwasreduced （204 8.9% and the daily temperature reduced 46.7% compared to ′17 .
