Abstract: The study on how meteorological factors affect the appearance quality of lycium barbarum has important practical value.Based on observed meteorological data and sampling data of Lycium barbarum L.cv.Ningqi No.1（Ningqi No.1） from 2018 to 2020,we analyzed the correlation between the appearance quality factors such as size,shape and color of Ningqi No.1 and the main meteorological factors in Jinghe County.The results show that in Jinghe County,the sunshine is sufficient in summer,which is conducive to the increase of longitudinal diameter,transverse diameter and fresh weight of Ningqi No.1.Under irrigated conditions,the appearance quality of Ningqi No.1 was not significantly related to precipitation except for color.And compared with the origin of Ningqi No.1（Ningxia Hui Autonomous Region）,the average summer temperature in Jinghe County is higher,which causes the fruit to ripen faster,making Ningqi No.1 ripe before it reaches its proper longitudinal diameter,and it is the climatic reason for the roundness of Ningqi No.1 fruit shape in Jinghe County.
