新疆精河宁杞1号的外观品质与气象条件关系研究

为摸清气象要素对精河种植的枸杞外观品质的影响，利用2018—2020年精河县气象资料和宁杞1号枸杞品种取样测定数据，研究了宁杞1号的大小、形状、色泽等外观品质要素与主要气象因子的相关关系。结果表明：精河地区夏季日照充足，有利于枸杞的纵径、横径和粒重的增加；在灌溉条件下精河枸杞外观品质中除色泽以外均与降水量关系不明显；与原产地相比，精河县夏季气温偏高，果实成熟加快，达不到宁杞1号品种应有的长度就已经成熟，这是精河地区宁杞1号果形偏圆的主要气候原因。此外，枸杞果实在采摘期和晾晒期不喜降水、寡照天气的特性与原产地宁夏类似，但精河地区此类气象问题要少。

Study on the correlation between appearance quality and meteorological factors of Ningqi No.1 in Jinghe County, Xinjiang

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 the 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, it is the climatic reason for the roundness of Ningqi No. 1 fruit shape in Jinghe County. In addition, the characteristics of NingQi No.1 preferring small amount of precipitation and longer sunshine weather during the picking and drying periods are similar to the origin, but there are few such meteorological problems in Jinghe County.
