Abstract： In order to study the comprehensive climate adaptability of each development stage of potato growth in Jianchuan County，meteorological observationdata from the Jianchuan National Meteorological Station （1991-202O）and growth -period observation data from the Jianchuan Agricultural Technology Station （2011 -2020）were used.The climate suitability method wasused to analyze the meteorological factor suitability duringthe key growth stages.Theresults show that precipitation is the key factor affcting potato growth in Jianchuan.Water demand is low during the early and late stages of growth but high during the tuber expansion stage. However，precipitation is limited from the bud stage to the seedling stage and from the tuber expansion stage to maturity，which affcts growth and yield formation.During the bud stage and tuber expansion stage，temperature and sunshine conditions are unfavorable for potato growth，while the remaining growth stages are suitable.
