Based on the continuous 37 year (1984-2020) phenological observation data of winter wheat at the National Agricultural Meteorological Observation Station in Tongren City, Guizhou Province, and combined with the meteorological observation data of the corresponding period, the changes and response relationships of the phenological periods of winter wheat and agricultural climate factors were systematically analyzed using kernel density estimation, climate trend analysis, correlation analysis, and multiple linear regression model. The results showed that the phenological periods of winter wheat in Tongren City from 1984 to 2020 generally showed a phased delay trend, among which the tillering period had the largest delay ［10.9 d· (10 a)^-1］. The duration of key growth stages was characterized by an extension at early stage ［vegetative growth period extended by 5.6 d· (10 a)^-1］, a shortening in the middle stage［vegetative and reproductive growth concurrent period shortened by -10.8 d· (10 a)^-1］, and relative stability at late stag ［reproductive growth period changed by 0.2 d· (10 a)^-1］. During the growth period of winter wheat, the agricultural climate elements generally showed an increase in temperature, a decrease in sunshine, and an increase in the fluctuation of water and heat conditions. Correlation analysis indicated that accumulated temperature and ground temperature were significantly positively correlated with the phenological period day numbers of sowing, emergence and three-leaf stage (P<0.001), while relative humidity and sunshine duration were significantly negatively correlated with the phenological periods of heading, flowering and milk-ripen stage (P<0.05 or P<0.01), yet the maturity period had no significant correlation with each climate factor. The results of multiple regression analysis showed that the phenological periods of winter wheat were most sensitive to accumulated temperature and ground temperature, followed by daily temperature range, precipitation and relative humidity, and less sensitive to sunshine duration. This study revealed the response characteristics of the phenological periods of winter wheat in the northeastern part of Guizhou Province to climate change, which can provide agricultural meteorological basis for the breeding and cultivation management of winter wheat varieties in the region.

基于贵州省铜仁市国家农业气象观测站连续37年（1984-2020年）冬小麦物候期观测资料，结合同期气象观测数据，采用核密度估计、气候趋势分析、相关性分析和多元线性回归模型，系统分析铜仁市冬小麦物候期及农业气候因子的变化特征及其响应关系。结果表明，1984-2020年铜仁市冬小麦物候期总体呈阶段性推迟趋势，其中分蘖期推迟幅度最大［10.9 d·（10 a）^-1］。关键生育阶段持续时间表现为前期延长［营养生长期延长5.6 d·（10 a）^-1］、中期缩短［营养与生殖生长并进期缩短-10.8 d·（10 a）^-1］，后期基本稳定（生殖生长期为0.2 d·（10 a）^-1）。冬小麦生育期间农业气候要素总体表现为气温升高、日照减少及水热条件波动增强。相关分析显示，≥10 ℃积温和地面温度与播种、出苗及三叶期物候期日序数呈显著正相关（P<0.001），而相对湿度和日照时数与孕穗、开花及乳熟期日序数呈显著负相关（P<0.05或P<0.01），成熟期与各气候因子相关不显著。多元回归分析表明，冬小麦物候期对≥10 ℃积温和地面温度的敏感性最强，其次为气温日较差、降水量和相对湿度，对日照时数的敏感性相对较弱。本研究揭示了黔东北地区冬小麦物候期对气候变化的响应特征，可为区域冬小麦品种选育和栽培管理提供农业气象依据。
